Description

Charging method, computer device and storage medium

Technical Field

The invention relates to the field of intelligent charging, in particular to a charging method, computer equipment and a storage medium which are regulated and controlled according to the real-time power load condition of a community.

Background

With the continuous improvement of the scientific and technological level and the living standard of people, more and more people start to buy the car to promote the convenience of life, improve the quality of life. However, as the capacity of the current automobiles is continuously increased, the emission of automobile exhaust has great influence on the ecological environment. In order to improve the increasingly worsened ecological environment, the electric automobile operates, the electric automobile provides energy to drive the vehicle to run through electric power, automobile exhaust cannot be generated in the running process, and the electric automobile has great effects of reducing the automobile exhaust and improving the environmental pollution. But the battery is limited by the development bottleneck of the battery technology of the electric automobile, the endurance mileage of the electric automobile is generally low at present, and the long-time long-distance use of people cannot be met, so that more electric automobile owners can charge the electric automobile in residential communities to meet the use requirements.

However, the charging demand of the car owners in the community is gradually strong, and the problem that the electricity consumption of community residents has a safety upper limit at the same time is that the normal electricity consumption of the residents is influenced and even an electricity consumption safety accident is caused if the new energy automobile is charged in the peak electricity consumption period. The current charging regulation and control mode is that when the total current of electricity consumption of the community exceeds a safe current threshold, the charging regulation and control is generally realized by regulating and reducing the charging current of partial or all charging equipment one by one or in batches. However, the charging regulation and control time is long due to the adoption of the mode of regulating and reducing the charging current of the charging equipment one by one, and the requirement can be met only by charging regulation and control for many times; by adopting a batch regulating charging mode, when the charging current required to be regulated and reduced is uniformly distributed to the charging equipment with larger charging current, the charging equipment with larger charging current is likely to be directly shut down; when the charging current required to be regulated and reduced is uniformly distributed to all the charging devices, the charging current of the charging device with smaller charging current is more regulated and reduced or even shut down, and certain influence is brought to the charging efficiency of all the charging devices of the whole system, so that the regulation and control precision of the regulation and control mode is poorer, the regulation and control mode needs to be charged for multiple times to achieve a better effect, and the load of the charging device cannot be quickly and effectively regulated and controlled within a safety range at one time when the load of a community is higher, so that potential safety hazards exist and normal electricity utilization of community residents is influenced. Therefore, how to quickly and accurately regulate and control the charging current of the charging device to meet the requirement of the safety current threshold when the total community current exceeds the safety threshold becomes an important topic for the construction of the intelligent community charging facility.

Referring to fig. 1, a charging method according to a preferred embodiment of the present invention includes the following steps:

step S210: the method comprises the steps of obtaining a real-time electric load, wherein the real-time electric load comprises residential electricity consumption current and charging current of charging equipment.

In the embodiment, in the community, in order to facilitate charging of residents, the charging equipment is arranged near the community parking space so that users can conveniently use the charging equipment for charging after parking vehicles into the parking space. Furthermore, the charging devices are all connected into the charging method to receive the regulation and control instruction of the charging method to regulate and control charging.

Further, after the charging device is connected to the charging method, before performing charging regulation, a real-time power load of a community needs to be acquired and applied, where the real-time power load includes a residential electricity consumption current and a charging current of the charging device, and specifically, in this embodiment, the real-time power load is a sum of the residential electricity consumption current and the charging current of the charging device.

Further, since the power consumption current of the residential electric line and the charging current of the charging device are in a changing state along with the power consumption of the residents and the charging of the vehicle, the acquired real-time power load is also in a changing state, and accidents such as tripping and the like may be caused as the power consumption current of the residents or the charging current of the charging device is increased and exceeds the upper limit of the circuit line of the community. For example: the acquired residential electricity current is 1000A, the charging current of the charging device is 500A, and then the real-time power load is 1500A after 1000A + 500.

Step S220: and comparing the real-time electric load with a safe current threshold value to obtain a comparison result.

Further, after the real-time power load is obtained, the real-time power load and a pre-stored safe current threshold value need to be compared, and a comparison result is obtained. Further, the comparison result includes that the real-time electrical load is not less than the safe current threshold, or that the real-time electrical load is less than the safe current threshold.

It can be understood that because there is rated current in the community power line, exceed when too big in order to prevent community power consumption electric current rated current sets up factor of safety, according to rated current with factor of safety reachs safe current threshold value will charge when real-time electric load exceeds safe current threshold value and regulate and control in order to prevent the real-time electric load of community reaches or surpasses thereby circumstances such as tripping operation outage of causing of rated current. Further, in this embodiment, the safe current threshold is a product of the rated current of the community power grid and a safety factor. For example: the rated current of the community power grid is 2000A, the safety factor is 0.9, and then the safety current threshold value is 2000A x 0.9 ═ 1800A.

Further, since the safe current threshold is smaller than the rated current, if the real-time power load of the community is smaller than the safe current threshold, it indicates that the total load of the current community is low, and at this time, the charging current of the charging device can be increased to improve the charging efficiency; if the real-time power load of the community is greater than the safe current threshold, the total load of the current community is high, and charging regulation and control are required to be performed in time to reduce the charging current of the charging equipment, so that the electricity consumption of residents is preferentially guaranteed on the premise that the charging current does not exceed the safe current threshold. It is therefore desirable to compare the real-time electrical load and the safe current threshold to determine how to make charging regulations to maintain proper operation of the community grid.

Step S230: and calculating a total regulation and control current and at least one adjustable current of the charging equipment according to the comparison result, screening the charging equipment to be regulated and controlled according to the total regulation and control current and the at least one adjustable current, and obtaining a current regulation and control target value of the charging equipment to be regulated and controlled, wherein the current regulation and control target value comprises at least one of a first preset value, a second preset value, a third preset value and 0.

Further, the total regulated current is a total current that the charging device connected to the power grid needs to be regulated down when the real-time power load is not less than the safety current threshold, or a total current that the charging device connected to the power grid needs to be regulated up when the real-time power load is less than the safety current threshold.

Further, in order to keep the community power load stable, the charging current of the charging device needs to be adjusted down or increased according to the real-time power load condition of the community power grid, and therefore the total adjusting current needs to be calculated according to the comparison result. Further, in this embodiment, the total regulated current includes a total regulated down current or a total regulated up current. The total regulating current is the sum of charging currents required to be regulated and reduced by all charging equipment in the power grid when the real-time power load is greater than the safe current threshold; and the total regulating current is the sum of charging currents required to be regulated and increased by all charging equipment in the power grid when the real-time power load is smaller than the safe current threshold. For example: when the real-time power load is 20A higher than the safe current threshold, the total regulating current is a total regulating and reducing current, and the total regulating and reducing current is 20A; and when the real-time power load is 10A lower than the safe current, the total regulating current is a total regulating current, and the total regulating current is 10A.

Further, in order to determine how to perform charging regulation and control, an adjustable current of the charging device needs to be further calculated, where the adjustable current is a sum of charging currents required to be regulated and reduced by all the charging devices in the power grid, and the charging current is regulated and reduced to at least one of the second preset value, the third preset value, and 0, or the charging current is regulated and increased to at least one of the third preset value, the second preset value, and the first preset value, and is a sum of charging currents required to be regulated and increased. It can be understood that, since the charging current of the charging device needs to be adjusted or controlled according to the real-time power load, the adjustable current includes an adjustable decreasing current and an adjustable increasing current, the adjustable decreasing current and the total adjusting current are correspondingly set as a basis for adjusting and decreasing the charging current of the charging device, and the adjustable decreasing current is a sum of charging currents that are required to be adjusted and decreased by all the charging devices in the power grid to decrease the charging current to at least one of the second preset value, the third preset value and 0; the adjustable boost current is the sum of the charging currents which are required to be boosted by all the charging equipment in the power grid to the third preset value, the second preset value and any one of the first preset values. Further, the adjustable boost current and the total boost current are correspondingly set to serve as a basis for boosting the charging current of the charging equipment. For example, currently, the power grid includes 1 charging device a, the charging current of the charging device a is 31A, in this embodiment, there are three current levels, which are 32A, 16A and 10A respectively, then the adjustable up current is 1A, and the adjustable down current is 15A, 21A or 31A.

Further, in order to ensure the safety of charging regulation, when charging current is regulated and reduced, it is required to ensure that the adjustable reduction current is not less than the total regulation and reduction current, that is, the sum of the charging currents regulated and reduced by all the charging devices is not less than the total regulation and reduction current, and when charging current is regulated and increased, it is required to ensure that the adjustable increase current is not greater than the total regulation and increase current, that is, the sum of the charging currents regulated and increased by all the charging devices is not greater than the total regulation and increase current, so as to ensure that the current of the regulated and controlled charging devices is not greater than the safety current threshold.

Further, when the received comparison result indicates that the real-time power load is not less than the safe current threshold, it indicates that the current community load is high, the charging current of the charging device needs to be reduced, and at this time, the total reduction current needs to be calculated, and meanwhile, the adjustable reduction current of the charging device needs to be calculated in order to determine how to perform charging regulation, so that the charging device to be regulated is screened according to the total reduction current and the adjustable reduction current, and the current regulation target value of the charging device to be regulated is obtained.

Further, when the received comparison result indicates that the real-time power load is smaller than the safe current threshold, it indicates that the current community load is low, the charging current of the charging device needs to be increased, at this time, the total increase current needs to be calculated, and meanwhile, the adjustable increase current of the charging device needs to be calculated in order to determine how to perform charging regulation, so that the charging device to be regulated is screened according to the total increase current and the adjustable increase current, and the current regulation target value of the charging device to be regulated is obtained.

Further, in this embodiment, the charging devices are further divided into at least one charging set according to the charging current of the charging device, and the charging device is selected from the charging set as a charging device to be regulated according to the total regulation current and the adjustable current, which can be understood as a charging device that needs to regulate the charging current or regulate the charging current. Further, in this embodiment, the charging set includes a first charging set, a second charging set and a third charging set, and the dividing further divides the charging device with the charging current not greater than the first preset value and greater than the second preset value into the first charging set, divides the charging device with the charging current not greater than the second preset value and greater than the third preset value into the second charging set, and divides the charging device with the charging current not greater than the third preset value into the third charging set. In this embodiment, the first preset value is 32A, the second preset value is 16A, and the third preset value is 10A. It can be understood that dividing the charging devices into different charging sets through charging current differences facilitates fast calculation of the level of the adjustable current and comparison of the adjustable current with the total regulation current, thereby fast screening out the charging devices to be regulated and calculating the current regulation target values of the charging devices to be regulated. For example: the power grid comprises a charging device a, a charging device b and a charging device c, wherein the charging current of the charging device a is 30A, the charging current of the charging device b is 28A, the charging current of the charging device c is 25A, and the charging device a, the charging device b and the charging device c are all divided into a first charging set as the three current values of 30A, 28A and 25A are all larger than 16A and smaller than 32A; the power grid comprises a charging device d, a charging device e and a charging device f, the charging current of the charging device d is 22A, the charging current of the charging device e is 20A, the charging current of the charging device c is 15A, the two current values of 22A and 20A are larger than 16A and smaller than 32A, so that the charging device d and the charging device e are classified into a first charging set, and the charging device f is classified into a second charging set because 15A is larger than 10A and smaller than 16A; the charging system comprises a charging device A, a charging device B, a charging device C, a charging device D and a charging device E, wherein the charging current of the charging device A is 20A, the charging current of the charging device B is 25A, the charging current of the charging device C is 15A, the charging current of the charging device D is 9A, the charging current of the charging device E is 8A, then the charging device A and the charging device B are classified into a first charging set, the charging device C is classified into a second charging set, and the charging device D and the charging device E are classified into a third charging set. In summary, since the current value of the charging device in the power grid is between 0 and 32A, when the charging sets are divided, the charging device in the power grid can be divided into at least one charging set.

Further, in this embodiment, when the charging device performs current regulation and reduction, the current regulation and control target value is a first preset value, a second preset value, a third preset value or 0, so that when the adjustable reduction current is calculated, the adjustable reduction current can be obtained according to a difference between the current and the first preset value, the second preset value, the third preset value or 0. Further, in this embodiment, when the charging devices of the first charging set, the second charging set, and the third charging set adjust the charging current, the charging devices adjust the charging current in order of the first charging set, the second charging set, and the third charging set. For example: when the charging current is adjusted to be reduced, the charging current of the charging equipment of the first charging set is preferentially adjusted to be reduced to the first preset value, then the charging current of the charging equipment of the second charging set is adjusted to be reduced to the second preset value, then the charging current of the charging equipment of the third charging set is adjusted to be reduced to 0, then the charging current of the charging equipment of the first charging set is adjusted to be reduced to the second preset value, and finally the charging current of the charging equipment of the first charging set is adjusted to be reduced to 0.

Further, in this embodiment, when the charging device performs current regulation, the current regulation target value is a first preset value, a second preset value, and a third preset value, so that when calculating the adjustable current, the adjustable current can be obtained according to the first preset value, the second preset value, the third preset value, and the current. Further, in this embodiment, when the charging devices of the first charging set, the second charging set, and the third charging set adjust the charging current, the charging devices adjust the charging current sequentially in the order of the third charging set, the second charging set, and the first charging set. For example: when the charging current is adjusted, the charging current of the charging equipment in the third charging set is preferentially adjusted to the third preset value, then the charging current of the charging equipment in the second charging set is adjusted to the second preset value, then the charging current of the charging equipment in the first charging set is adjusted to the first preset value, then the charging current of the charging equipment in the third charging set is adjusted to the second preset value, and finally the charging current of the charging equipment in the third charging set is adjusted to the first preset value.

Further, the charging current of the charging device in the first charging set may be reduced to the second preset value, the third preset value, or 0, the charging current of the charging device in the second charging set may be reduced to the second preset value or 0, and the charging current of the charging device in the third charging set may be reduced to 0, so in this embodiment, the adjustable reduction current includes a first adjustable reduction current, a second adjustable reduction current, a third adjustable reduction current, a fourth adjustable reduction current, a fifth adjustable reduction current, and a sixth adjustable reduction current, the first adjustable reduction current is a sum of the first reference drop current, the first reference drop current is a difference between the charging current of the charging device in the first charging set and the second preset value, the second adjustable reduction current is a sum of the second reference drop current, and the second reference drop current is a sum of the charging current of the charging device in the second charging set and the third preset value The third adjustable reduction current is equal to the charging current of the charging device in the third set, the fourth adjustable reduction current is equal to the sum of the fourth adjustable reduction current, the fourth adjustable reduction current is equal to the difference between the charging current of the charging device in the first charging set and the third preset value, the fifth adjustable reduction current is equal to the sum of the fifth adjustable reduction current, the fifth adjustable reduction current is equal to the charging current of the charging device in the second charging set, the sixth adjustable reduction current is equal to the sum of the sixth adjustable reduction current, and the sixth adjustable reduction current is equal to the charging current of the charging device in the first charging set.

Further, the charging current of the charging device in the first charging set may be adjusted to the first preset value, the charging current of the charging device in the second charging set may be adjusted to the second preset value or the first preset value, the charging current of the charging device in the third charging set may be adjusted to the third preset value, the second preset value or the first preset value, so that the adjustable current includes a first adjustable current, a second adjustable current, a third adjustable current, a fourth adjustable current, a fifth adjustable current and a sixth adjustable current, the first adjustable current is a sum of first quasi-adjusted currents, the first quasi-adjusted current is a difference between the third preset value and the charging current of the charging device in the third charging set, and the second adjustable current is a sum of second quasi-adjusted currents, the second quasi-tune-up current is a difference between the second preset value and a charging current of a charging device within the second charging set, the third adjustable boost current is a sum of third quasi-adjustable boost currents, the third quasi-adjustable boost currents being a difference between the first preset value and charging currents of charging devices within the first charging set, the fourth adjustable boost current is a sum of fourth quasi-adjustable boost currents, the fourth quasi-adjustable boost currents being a difference between the second preset value and charging currents of charging devices within the third charging set, the fifth adjustable ramp-up current is a sum of fifth quasi-adjusted ramp-up currents, the fifth quasi-adjusted ramp-up currents being a difference between the first preset value and charging currents of charging devices within the second charging set, the sixth adjustable boost current is the sum of sixth quasi-adjustable boost currents, and the sixth quasi-adjustable boost current is the difference between the first preset value and the charging current of the charging device in the third charging set.

Further, after the total regulation and reduction current and the adjustable reduction current are calculated, it is necessary to further screen the charging device to be regulated from the first charging set, the second charging set and the third charging set according to the total regulation and reduction current and the adjustable reduction current and determine a current regulation and control target value of the charging device to be regulated.

Further, when the first adjustable buck current is not less than the total adjustable buck current, screening part of the charging devices in the first charging set as the charging devices to be regulated, and obtaining that the current regulation target value of the charging devices to be regulated in the first charging set is the second preset value. It can be understood that if the first adjustable reduction current is not less than the total regulation current, it indicates that the regulation requirement can be met by partially reducing the charging devices in the first charging set to the second preset value, and therefore, part of the charging devices in the first charging set are screened as the charging devices to be regulated according to the sequence of charging access time. Further, the method is specifically configured to form a first turn-down sequence for the charging devices in the first charging set according to the sequence of charging access time, and screen a part of the charging devices from the first turn-down sequence as the charging devices to be regulated. Further, the method is specifically configured to sequentially accumulate the first reference drop currents of the charging devices in the first drop sequence to compare with the total drop current, and select the accumulated charging device corresponding to the first reference drop current as the charging device to be regulated when the sum of the first reference drop currents is not less than the total drop current. For example: the total regulating current is 20A, the charging devices in the first charging set are a charging device a, a charging device B and a charging device C, the charging access time of the charging device a is 8-point 1 min, the charging current is 24A, the charging access time of the charging device B is 8-point 30 min, the charging current is 31A, the charging access time of the charging device C is 9-point, the charging current is 27A, the first regulating sequence is the charging device a, the charging device B and the charging device C, the first adjustable reducing current is 8A +15A +11A ═ 34A, the first adjustable reducing current is greater than the total regulating current, the first regulating currents of the charging device a and the charging device B are accumulated to be 8A +15A ═ 23A, and are greater than the total regulating current 20A, the charging devices corresponding to 8A and 15A are selected from the first regulating sequence, namely, the charging equipment A and the charging equipment B are used as the charging equipment to be regulated and controlled; if the total regulating current is 33A, accumulating the first regulating current of the charging device a and the first regulating current of the charging device B to be 8A + 15A-23A, and if the total regulating current is smaller than 33A, continuing to accumulate the first regulating current of the charging device C to be 8A +15A + 11A-34A, and if the total regulating current is larger than 33A, selecting the third regulating current corresponding to the accumulated third regulating current, that is, the charging devices corresponding to 8A, 15A and 11A, from the first regulating sequence, that is, the charging device a, the charging device B and the charging device C, as the charging device to be regulated, and the current regulating value of the charging device to be regulated is 16A.

Further, the method is specifically configured to, when the first adjustable buck current is smaller than the total buck current and the sum of the first adjustable buck current and the second adjustable buck current is not smaller than the total buck current, screen all charging devices from the first charging set as the charging devices to be regulated, and obtain that the current regulation target value is the second preset value, and screen part of the charging devices from the second charging set as the charging devices to be regulated, and obtain that the current regulation target value is the third preset value. It can be understood that the first adjustable buck current is smaller than the total buck current, which indicates that the regulation of the charging current of the charging device in the first charging set to the second preset value still cannot meet the requirement of current regulation; further, if the sum of the first adjustable buck current and the second adjustable buck current is not less than the total buck current, it indicates that the charging current of the charging device in the first charging set is regulated to the second preset value, and then a selected part of the charging devices in the second charging set is regulated to the third preset value, which can meet the current regulation requirement, so that all the charging devices in the first charging set and a part of the charging devices in the second charging set are selected as the charging devices to be regulated, the current regulation target value of the charging device to be regulated in the first charging set is set to the second preset value, and the current regulation target value of the charging device to be regulated in the second charging set is set to the third preset value, which can meet the current regulation requirement.

Further, the method is specifically configured to form a second turn-down sequence for the charging devices in the second charging set according to the sequence of charging access time, and screen a part of the charging devices from the second turn-down sequence as the charging devices to be regulated. Further, the method is specifically configured to sequentially accumulate the second reference drop currents of the charging devices in the second drop sequence to compare with a difference between the total drop current and the first adjustable drop current, and select the charging device corresponding to the accumulated second reference drop current as the to-be-regulated charging device when the sum of the second reference drop currents is not less than the difference between the total drop current and the first adjustable drop current. For example: the total regulating current is 35A, the charging devices in the first charging set are charging device a, charging device B and charging device C, the first adjustable reducing current is 30A, the charging devices in the second charging set are charging device D, charging device E and charging device F, the charging access time of charging device D is 8-point 1 min, the charging current is 11A, the charging access time of charging device E is 8-point 30 min, the charging current is 13A, the charging access time of charging device F is 9-point, the charging current is 15A, the second adjustable reducing current is 1A +3A +5A ═ 9A, 30A +9A ═ 39A > 35A, that is, the sum of the first adjustable reducing current and the second adjustable reducing current is not less than the total regulating current, the second regulating sequence is charging device D, charging device E and charging device F, accumulating the second reference drop currents of the charging device D and the charging device E to 1A + 3A-4A, and accumulating the difference between the total drop current and the first adjustable drop current to 35A-30A-5A, where 4A is less than 5A, so as to further accumulate the second reference drop current of the charging device F to 1A +3A + 5A-9A, where 9A is greater than 5A, and further select the accumulated second reference drop current from the second drop sequence, that is, the charging devices corresponding to 1A, 3A, and 5A, that is, the charging device D, the charging device E, and the charging device F, as the charging device to be regulated, and the current regulation value of the charging device to be regulated is 10A.

Further, when the sum of the first adjustable reduction current and the second adjustable reduction current is smaller than the total reduction current and the sum of the first adjustable reduction current, the second adjustable reduction current and the third adjustable reduction current is not smaller than the total reduction current, all charging devices are screened from the first charging set as the charging devices to be regulated, the current regulation target value is obtained as the second preset value, all charging devices are screened from the second charging set as the charging devices to be regulated, the current regulation target value is obtained as the third preset value, part of the charging devices are screened from the third charging set as the charging devices to be regulated, and the current regulation target value is obtained as 0. It can be understood that the sum of the first adjustable buck current and the second adjustable buck current is smaller than the total buck current, which indicates that the current regulation and control requirements cannot be met by regulating the currents of all the charging devices in the first chargeable set to the second preset value and regulating the currents of the charging devices in the second chargeable set to the third preset value; further, if the sum of the first adjustable buck current, the second adjustable buck current and the third adjustable buck current is not less than the total buck current, it indicates that part of the charging devices in the third charging set is screened as the quasi-charging device on the basis of reducing the currents of all the charging devices in the first chargeable set to the second preset value and reducing the currents of the charging devices in the second chargeable set to the third preset value, and the current regulation value of the quasi-charging device in the third charging set is set to 0, so that the current regulation requirement can be met.

Further, the method is specifically configured to form a third turn-down sequence for the charging devices in the third charging set according to the sequence of charging access time, and screen a part of the charging devices from the third turn-down sequence as the charging devices to be regulated. Further, the method is specifically configured to sequentially accumulate the third reference drop currents of the charging devices in the third drop sequence, compare the third reference drop currents with a difference value obtained by subtracting a sum of the first adjustable drop current and the second adjustable drop current from the total drop current, and select the charging device corresponding to the accumulated third reference drop current as the to-be-regulated charging device when the sum of the third reference drop currents is not less than the difference value obtained by subtracting a sum of the first adjustable drop current and the second adjustable drop current from the total drop current. For example: the total regulated current is 55A, the charging devices in the first charging set are charging device a, charging device B and charging device C, the first adjustable reduced current is 30A, the charging devices in the second charging set are charging device D, charging device E and charging device F, the second adjustable reduced current is 8A, the charging device G and charging device H of the charging device in the third charging set are charging device I, the charging access time of the charging device G is 8: 1, the charging current is 9A, the charging access time of the charging device H is 8: 30, the charging current is 6A, the charging access time of the charging device I is 9, the charging current is 4A, the third adjustable reduced current is 9A +6A +4A ═ 19A, 30A +8A +19A ═ 57A > 55A, that is, the first adjustable reduced current, The sum of the second adjustable buck current and the third adjustable buck current is not less than the total buck current, the third buck sequence is a charging device G, a charging device H, and a charging device I, the third buck current of the charging device G and the charging device H is accumulated to 9A +6A to 15A, the difference between the total buck current and the first adjustable buck current and the second adjustable buck current is 55A-30A-8A to 17A, 15A is less than 17A, so that the third buck current of the charging device I is further accumulated to 9A +6A +4A to 19A, and 19A is greater than 17A, and then charging devices corresponding to the accumulated third buck current, that is, 9A, 6A, and 4A, that is, the charging device G, the charging device H, and the charging device I are further selected from the third buck sequence as the charging device to be regulated, and the current regulation value of the charging equipment to be regulated is 0.

It can be understood that if the sum of the first adjustable buck current, the second adjustable buck current and the third adjustable buck current is less than the total buck current, it indicates that the charging currents of all charging devices in the first charging set are regulated to be reduced to the second preset value, the charging currents of all charging devices in the second charging set are regulated to be reduced to be the third preset value, and the charging currents of all charging devices in the third charging set are regulated to be reduced to 0, which still cannot meet the requirement of current regulation; further, if the sum of the fourth adjustable reduction current, the second adjustable reduction current, and the third adjustable reduction current is not less than the total reduction current, it indicates that the charging currents of some charging devices in the first charging set are reduced to the third preset value, the charging currents of another part of charging devices are reduced to the second preset value, the charging currents of all charging devices in the second charging set are reduced to the third preset value, and the charging currents of all charging devices in the third charging set are reduced to 0, so that the current regulation and control requirements can be met.

Further, a first current difference value of the charging device in the first regulating sequence is calculated, the first current difference value is equal to a difference value between the second preset value and the third preset value, the first current difference value is sequentially accumulated to be compared with a difference value obtained by subtracting a sum of the first adjustable reducing current, the second adjustable reducing current and the third adjustable reducing current from the total regulating current, when the sum of the first current difference value is not less than the sum of the total regulating current minus the first adjustable reducing current, the second adjustable reducing current and the third adjustable reducing current, a current regulation value of the charging device corresponding to the accumulated first current difference value is obtained as the third preset value, and current regulation values of other charging devices in the first charging set are obtained as the second preset value. For example: the total regulating current is 68A, the charging devices in the first charging set are a charging device a, a charging device B and a charging device C, the charging access time of the charging device a is 8-point 1 min, the charging current is 24A, the charging access time of the charging device B is 8-point 30 min, the charging current is 31A, the charging access time of the charging device C is 9-point, and the charging current is 27A, then the first regulating sequence is the charging device a, the charging device B and the charging device C, the first regulating current is 24A-16A +31A-16A +27A-16A ═ 34A, the charging devices in the second charging set are a charging device D, a charging device E and a charging device F, the second regulating current is 8A, and the charging device G and the charging device H in the third charging set, the third adjustable buck current is 19A, 34A +8A +19A is less than 68A, that is, the sum of the first adjustable buck current, the second adjustable buck current, and the third adjustable buck current is less than the total adjustable buck current, and the fourth adjustable buck current is 24A-10A +31A-10A +27A +10A — 52A, and 52A +8A +19A is 79A > 68A, that is, the sum of the second adjustable buck current, the third adjustable buck current, and the fourth adjustable buck current is greater than the total adjustable buck current. At this time, it is obtained that the first current difference value of the charging device in the first turn-down sequence is 16A-10A ═ 6A, the difference value between the total turn-down current and the first adjustable turn-down current, the second adjustable turn-down current, and the third adjustable turn-down current is 68A-30A-8A-19A ═ 11A, and 6A +6A ═ 12A > 11A, so that the current regulation value of the charging device corresponding to the accumulated first current difference value in the first turn-down sequence, that is, the charging device a and the charging device B, is further obtained as the third preset value, and the current regulation value of the other charging devices in the first charge set, that is, the charging device C, is obtained as the second preset value.

Further, when the sum of the fourth adjustable buck current, the second adjustable buck current and the third adjustable buck current is smaller than the total buck current and the sum of the fifth adjustable buck current, the fourth adjustable buck current and the third adjustable buck current is not smaller than the total buck current, all charging devices are screened from the first charging set as the charging devices to be regulated, and a current regulation target value of the charging devices in the first charging set is obtained as the third preset value, and all charging devices are screened from the second charging set as the charging devices to be regulated, and a current regulation target value of a part of the charging devices in the second charging set is obtained as the third preset value, and a current regulation target value of another part of the charging devices is 0, and all charging devices are screened from the third charging set as the charging devices to be regulated, and the current regulation target value is 0. It can be understood that if the sum of the fourth adjustable buck current, the second adjustable buck current and the third adjustable buck current is less than the total buck current, it indicates that the charging currents of all charging devices in the first charging set are regulated to be reduced to the third preset value, the charging currents of all charging devices in the second charging set are regulated to be reduced to be the third preset value, and the charging currents of all charging devices in the third charging set are regulated to be reduced to 0, which is not a requirement of current regulation; further, the charging currents of all the charging devices in the first charging set are adjusted to be reduced to the third preset value, the charging currents of part of the charging devices in the second charging set are adjusted to be reduced to 0, the charging currents of the other part of the charging devices are adjusted to be reduced to the third preset value, and the charging currents of all the charging devices in the third charging set are adjusted to be reduced to 0, namely the current regulation requirement is met.

Further, a second current difference value of the charging device in the second regulating sequence is calculated, the second current difference value is equal to the third preset value, the first current difference value is sequentially accumulated to be compared with a difference value obtained by subtracting the sum of the second adjustable reducing current and the third adjustable reducing current from the total regulating current, and when the sum of the second current difference value is not less than the difference value obtained by subtracting the sum of the second adjustable reducing current and the third adjustable reducing current from the total regulating current, the current regulation value of the charging device corresponding to the second current difference value is 0, and the current regulation values of other charging devices in the second charging set are the third preset value. For example: the total regulating current is 90A, the charging devices in the first charging set are a charging device a, a charging device B and a charging device C, the fourth regulating current is 48A, the charging devices in the second charging set are a charging device D, a charging device E and a charging device F, the charging access time of the charging device D is 9: 1 min, the charging current is 11A, the charging access time of the charging device E is 9: 30 min, the charging current is 13A, the charging access time of the charging device F is 10: 15A, the second regulating sequence is the charging device D, the charging device E and the charging device F, the second regulating current is 11A-10A +13A-10A +15A-10A ═ 9A, and the charging device G and the charging device H of the charging device in the third charging set, charging device I, where the third adjustable buck current is 19A, where 48A +9A +19A is 76A < 90A, that is, the sum of the fourth adjustable buck current, the second adjustable buck current, and the third adjustable buck current is less than the total adjustable buck current, and the fifth adjustable buck current is 11A +13A + 15A: 39A, and 48A +39A +19A is 106A > 90A, that is, the sum of the fifth adjustable buck current, the fourth adjustable buck current, and the third adjustable buck current is greater than the total adjustable buck current. At this time, the second current difference value of the charging device in the second turn-down sequence is calculated to be 10A-0 ═ 10A, the difference value of the total turn-down current and the second adjustable turn-down current, the third adjustable turn-down current, and the fourth adjustable turn-down current is calculated to be 90A-48A-8A-19A ═ 15A, and 10A +10A ═ 20A > 15A, so that the current regulation value of the charging device corresponding to the accumulated second current difference value in the second turn-down sequence, that is, the charging device D and the charging device E, is further obtained to be 0, and the current regulation value of the other charging devices in the second charging set, that is, the charging device F, is obtained to be the third preset value.

Further, when the sum of the fifth adjustable buck current, the fourth adjustable buck current and the third adjustable buck current is less than the total buck current and the sum of the sixth adjustable buck current, the fifth adjustable buck current and the third adjustable buck current is not less than the total buck current, screening all charging devices from the first charging set as the charging devices to be regulated, and obtaining that the current regulation target values of the charging devices in the first charging set are the third preset value, and the current regulation target values of the other part of the charging devices are 0, and screening all charging devices from the second charging set as the charging devices to be regulated, and obtaining that the current regulation target value is 0, screening all charging devices from the third charging set as the charging devices to be regulated, and obtaining that the current regulation target value is 0. It can be understood that if the sum of the fifth adjustable buck current, the fourth adjustable buck current and the third adjustable buck current is less than the total buck current, it indicates that the charging currents of all charging devices in the first charging set are regulated to be reduced to the second preset value, the charging currents of all charging devices in the second charging set are regulated to be reduced to 0, and the charging currents of all charging devices in the third charging set are regulated to be reduced to 0, which is still not a requirement for current regulation; further, the charging current of a part of the charging devices in the first charging set is reduced to 0, the charging current of another part of the charging devices is reduced to the third preset value, the charging current of all the charging devices in the second charging set is reduced to 0, and the charging current of all the charging devices in the third charging set is reduced to 0, which is a demand for current regulation.

Further, a third current difference value of the charging device in the third regulating-decreasing sequence is calculated, the third current difference value is equal to the third preset value, the third current difference value is sequentially accumulated to be compared with a difference value obtained by subtracting a sum of the third adjustable decreasing current, the fourth adjustable decreasing current and the fifth adjustable decreasing current from the total regulating-decreasing current, when the sum of the third current difference value is not less than a difference value obtained by subtracting a sum of the fifth adjustable decreasing current, the fourth adjustable decreasing current and the third adjustable decreasing current from the total regulating-decreasing current, a current regulation value of the charging device corresponding to the third current difference value is obtained to be 0, and current regulation values of other charging devices in the first charging set are obtained to be the third preset value. For example: the total regulating current is 110A, the charging devices in the first charging set are a charging device a, a charging device B and a charging device C, the charging access time of the charging device a is 8-point 1 min, the charging current is 24A, the charging access time of the charging device B is 8-point 30 min, the charging current is 31A, the charging access time of the charging device C is 9-point, and the charging current is 23A, then the first regulating sequence is the charging device a, the charging device B and the charging device C, the fourth regulating current is 24A-10A +31A-10A +23A-10A ═ 48A, the charging devices in the second charging set are a charging device D, a charging device E and a charging device F, the fifth regulating current is 41A, and the charging device G and the charging device H in the third charging set, charging device I, where the third adjustable buck current is 19A, 48A +41A +19A is 108A < 110A, that is, the sum of the fifth adjustable buck current, the fourth adjustable buck current, and the third adjustable buck current is less than the total adjustable buck current, and the sixth adjustable buck current is 24A +31A +23A is 78A, and 78A +41A +19A is 138A > 110A, that is, the sum of the sixth adjustable buck current, the fifth adjustable buck current, and the third adjustable buck current is greater than the total adjustable buck current. At this time, a third current difference value of the charging device in the third turn-down sequence is calculated to be 10A-0-10A, a difference value of the total turn-down current and the third adjustable turn-down current, the fourth adjustable turn-down current, and the fifth adjustable turn-down current is calculated to be 110A-19A-48A-41A-2A, and 10A > 2A, so that a current regulation value of the charging device corresponding to the accumulated third current difference value in the first turn-down sequence, that is, the charging device a, is further obtained to be 0, and current regulation values of other charging devices in the first charging set, that is, the charging device B and the charging device C, are obtained to be the third preset value.

Further, after the total regulated current and the adjustable regulated current are calculated, it is necessary to further screen a charging device to be regulated from the first charging set, the second charging set, and the third charging set according to the total regulated current and the adjustable regulated current, and determine a current regulation target value of the charging device to be regulated.

Further, when the first adjustable boost current is not less than the total boost current, screening a part of charging devices in the third charging set as the charging devices to be regulated, and obtaining that a current regulation target value of the charging devices to be regulated in the third charging set is the third preset value. It can be understood that the first adjustable boost current is not less than the total boost current, which indicates that the requirement of charging regulation and control can be met after the charging current is adjusted and boosted only from the charging devices screened from the third charging set, so that the charging device with the charging current of 0 in the third charging set is preferentially selected as the charging device to be regulated and controlled. It can be understood that, due to the charging regulation, the charging current of part of the charging devices is regulated to be reduced to 0 to meet the requirement of the charging regulation, so when the charging current is regulated, the charging device with the charging current of 0 is preferentially regulated to meet the charging requirement of the user. Further, after the charging devices with the charging and charging current of 0 are screened, screening part of the charging devices from the first charging set as the charging devices to be regulated according to the sequence of charging access time, and obtaining that the current regulation and control target value of the charging devices to be regulated and controlled is the third preset value.

And further, the method is specifically used for forming a first lifting sequence according to the sequence of charging access time, and screening part of charging equipment in the first lifting sequence as the charging equipment to be regulated. Further, the method is specifically configured to sequentially accumulate the first quasi lift currents of the charging devices in the first lift sequence to compare with the total lift current, and select, when the sum of the first quasi lift currents is greater than the total lift current, the charging device corresponding to the other accumulated first quasi lift currents except the last first quasi lift current as the charging device to be regulated. For example: the total regulated current is 8A, the charging devices in the third charging set are a charging device a, a charging device B and a charging device C, the charging access time of the charging device a is 8-point and 1-minute, the charging current is 2A, the charging access time of the charging device B is 8-point and 30-minute, the charging current is 9A, the charging access time of the charging device C is 9-point, and the charging current is 5A, then the first regulated sequence is the charging device a, the charging device B and the charging device C, the first adjustable regulated current is 10A-2A +10A-9A + 10A-5A-14A, the first adjustable regulated current is greater than the total regulated current, the first regulated current of the charging device a and the first quasi regulated current of the charging device B are summed to be 8A + 1A-9A, and is greater than the total regulated current 8A, the accumulated first reference regulated currents are 8A and 1A, the last first reference regulated current is 1A, the other accumulated first reference regulated currents except the last first reference regulated current are 8A, the charging device corresponding to 8A is the charging device A, and the charging device A is selected as the charging device to be regulated.

Further, if the total boost current is smaller than the first quasi-boost current of any charging device in the third charging set, in this case, boosting the charging current of any charging device in the third charging set to the third preset value will cause the real-time power load to exceed the safety current threshold, so that the charging device is not selected from the third charging set as the charging device to be regulated.

Further, when the first adjustable boost current is smaller than the total adjustable boost current and the sum of the first adjustable boost current and the second adjustable boost current is not smaller than the total adjustable boost current, all charging devices are screened from the third charging set as the charging devices to be regulated, the current regulation target value of the charging devices to be regulated in the third charging set is obtained as the third preset value, part of the charging devices are screened from the second charging set as the charging devices to be regulated, and the current regulation target value of the charging devices to be regulated in the second charging set is obtained as the second preset value. It can be understood that the first adjustable boost current is smaller than the total boost current, which indicates that when the charging currents of all the charging devices in the third charging set are all boosted to the third preset value, surplus current still exists, and therefore, it is necessary to continuously screen a part of the charging devices as charging devices to be regulated to perform charging regulation; further, when the sum of the first adjustable boost current and the second adjustable boost current is not less than the total boost current, it indicates that the requirement of charging regulation and control can be met by screening part of the charging devices from the second charging set, so a second boost sequence is further formed according to the sequence of charging access time, and part of the charging devices are screened from the second boost sequence as the charging devices to be regulated and controlled.

Further, the method is specifically configured to sequentially accumulate the second quasi lift currents of the charging devices in the second lift sequence to compare with a difference between the total lift current and the first adjustable lift current, and select, when the sum of the second quasi lift currents is greater than the difference between the total lift current and the first adjustable lift current, the charging device corresponding to the other accumulated second quasi lift currents except for the last second quasi lift current as the charging device to be regulated. For example: the total regulated current is 17A, the charging devices in the third charging set are a charging device a, a charging device B and a charging device C, the first adjustable current is 10A, the charging devices in the second charging set are a charging device D, a charging device E and a charging device F, the charging access time of the charging device D is 8-point 1 min, the charging current is 11A, the charging access time of the charging device E is 8-point 30 min, the charging current is 13A, the charging access time of the charging device F is 9-point, the charging current is 15A, the second adjustable current is 16A-11A +16A-13A +16A-15A 9A, 10A +9A is 19A > 17A, that is, the sum of the first adjustable current and the second adjustable current is not less than the total regulated current, and the second regulated sequence is that the charging device D, the charging device B and the charging device C are in the third charging set, and the second charging set is a charging device D, a and a charging device C, a and a charging device C, Charging equipment E and charging equipment F, accumulating second accurate regulated currents of the charging equipment D and the charging equipment E into 5A + 3A-8A, wherein the difference value between the total regulated current and the first adjustable regulated current is 17A-10A-7A, 8A is larger than 7A, the second accurate regulated currents are larger than the total regulated current, the accumulated second accurate regulated currents are 5A and 3A, the last second accurate regulated current is 3A, other accumulated second accurate regulated currents except the last second accurate regulated current are removed to be 5A, the charging equipment corresponding to 5A is charging equipment D, and the charging equipment D is selected to be used as the charging equipment to be regulated.

Further, if the difference between the total adjusted current and the first adjustable current is smaller than the second adjusted current of any charging device in the second charging set, in this case, adjusting the charging current of any charging device in the second charging set to the second preset value will cause the real-time power load to exceed the safe current threshold, so that the charging device is not selected from the second charging set as the charging device to be adjusted.

Further, the method is specifically configured to, when the sum of the first adjustable boost current and the second adjustable boost current is smaller than the total boost current and the sum of the first adjustable boost current, the second adjustable boost current, and the third adjustable boost current is not smaller than the total boost current, screen all charging devices from the third charging set as the charging devices to be regulated, obtain that a current regulation target value of the charging devices to be regulated in the third charging set is the third preset value, screen all charging devices from the second charging set as the charging devices to be regulated, obtain that a current regulation target value of the charging devices to be regulated in the second charging set is the second preset value, and screen a part of the charging devices from the first charging set as the charging devices to be regulated, and obtaining that the current regulation target value of the charging equipment to be regulated in the first charging set is the first preset value. It can be understood that the sum of the first adjustable boost current and the second adjustable boost current is smaller than the total boost current, which indicates that when the charging currents of all the charging devices in the third charging set are all boosted to the third preset value, and when the charging currents of all the charging devices in the second charging set are all boosted to the second preset value, surplus currents still exist, so that part of the charging devices needs to be screened continuously as the charging devices to be regulated to perform charging regulation; further, when the sum of the first adjustable boost current, the second adjustable boost current and the third adjustable boost current is not less than the total boost current, it indicates that the requirement of charging regulation and control can be met by further screening part of the charging devices from the first charging set to perform charging regulation and control, so that a third boost sequence is further formed according to the sequence of charging access time, and part of the charging devices is screened from the third boost sequence to be used as the charging devices to be regulated and controlled.

Further, the method is specifically configured to sequentially accumulate the third quasi lift currents of the charging devices in the third lift sequence to be compared with a difference obtained by subtracting a sum of the first adjustable lift current and the second adjustable lift current from the total lift current, and select, as the charging device to be regulated, the charging device corresponding to the accumulated third quasi lift currents except for the last third quasi lift current when the sum of the third quasi lift currents is greater than the difference obtained by subtracting the sum of the first adjustable lift current and the second adjustable lift current from the total lift current. For example: the total regulated current is 26A, the charging devices in the third charging set are a charging device a, a charging device B and a charging device C, the first adjustable regulated current is 10A, the charging devices in the second charging set are a charging device D, a charging device E and a charging device F, the second adjustable current is 9A, the charging devices in the first charging set are a charging device G, a charging device H and a charging device I, the charging access time of the charging device G is 8 points and 1 minute, the charging current is 30A, the charging access time of the charging device H is 8 points and 30 minutes, the charging current is 27A, the charging access time of the charging device I is 9 points, and the charging current is 25A, then the third adjustable current is 32A-30A +32A-27A + 32A-25A-14A, 10A +9A + 14A-33A > 26A, i.e. the sum of the first adjustable ramp-up current, the second adjustable ramp-up current and the third adjustable ramp-up current is not less than the total ramp-up current, the third boost sequence is charging equipment G, charging equipment H and charging equipment I, the third quasi-boost currents of the charging equipment G and the charging equipment H are accumulated to be 2A + 6A-8A, the difference between the total regulated current and the first and second adjustable regulated currents is 26A-10A-9A-7A, 8A > 7A, greater than the total regulated current, the accumulated third regulated currents are 2A and 6A, the last third regulated current is 6A, the other accumulated third trimming rising current except the last third trimming rising current is 2A, and if the charging equipment corresponding to the 2A is the charging equipment G, selecting the charging equipment G as the charging equipment to be regulated.
