Description

Can avoid the sequential charging control system for electric vehicles of electric net overload

Technical field

The utility model relates to a kind of electric automobile roadside charging controller system.

Background technology

According to car industry " 12 " planning, the coming five years, Chinese Automobile Industry will be advocated the energy-saving automobile that development comprises new-energy automobile energetically.Pure electric automobile is subject to unprecedented attention.But the convenient charging problem of electric automobile is a bottleneck of puzzlement Development of Electric Vehicles always.

At present exist some problems in the use of electric automobile, concentrate (trickle charge or fill soon) charging in the roadside such as: electric automobile, cause electric net overload easily and collapse; Traditional charging device (charging station and charging column) car owner be difficult to search, and vehicle inconvenience is stopped and used; Fast charge mode shortens battery life, etc.These problems have seriously restricted popularizing and promoting of electric automobile.

The utility model content

For addressing the above problem, the purpose of this utility model is to provide a kind of sequential charging control system for electric vehicles of avoiding electric net overload.

The technical scheme that the invention for solving the technical problem adopts is:

Electric charging controlling box is connected with a plurality of railing type power supply stakes, each railing type power supply stake can be charged for an electric automobile, electric charging controlling box can be controlled the power supply state of railing type power supply stake, electric charging controlling box and the electric automobile wired or wireless communication that needs charging, and by internet and Charge Management center to center communications, the charging process of electric automobile is controlled and managed, because railing type power supply stake is to power by the section transformer of locality, therefore when charging vehicle arrives certain quantity, can increase local power load, thereby affect local electric power facility and resident's electricity consumption, restricting the development of roadside autonomous driving vehicle charging system.

For sort this problem out, power load management system is set, detect in real time section transformer electric load, and communicate by letter with electric charging controlling box and to adjust the charging control mode of electric charging controlling box, the quantity of control Vehicular charging is avoided electric net overload.

Management of power load module is in charge of the charging quantity of electric automobile, by current transformer the current conditions of section transformer is sampled, and will adopt data transmission to detect to the electric load detection module, management of power load module is known the electric load state of local section transformer by the electric load detection module.

Electric charging controlling box and the electric automobile wired or wireless communication that needs charging, obtain automobile number to be charged, report the data of vehicle to be charged to management of power load module by the power communication interface, management of power load module sends charging permission quota number according to the load condition of section transformer to electric charging controlling box, electric charging controlling box carries out Charge Management according to the quota number to each power supply stake, the quantity of control charging vehicle.

Further, when the vehicle number of application charging was counted greater than quota, electric charging controlling box divided into groups to take turns the current control charging according to quota quantities to required charging vehicle, allowed the automobile grouping of required charging take turns current charge.Allow the automobile grouping of required charging take turns current charge, can not only reduce the load of section transformer, and can avoid occurring the situation that certain automobile can not charge always, applicability and the practicality of its allocation scheme are better.

With reference to Fig. 6-shown in Figure 9, concrete Charge Management control procedure of the present utility model is as follows: electric charging controlling box communicates with the vehicle that needs charging, be the tabulation of vehicle resume charging service, obtain the vehicle number M of application charging, communicate by letter with power load management system and to obtain the section transformer and distribute to the quota of electric charging controlling box and count N, if the vehicle number M of application charging counts N less than quota, then each vehicle enters charged state.

If the vehicle number M of application charging counts N greater than quota, then allow vehicle report the remaining electricity of battery, charging control is got rid of vehicle according to electricity more than the battery of vehicle, need the vehicle of artificial contact power supply then directly enter charged state if the communication module of vehicle breaks down, stop charging after Vehicular charging is full of and send out to the car owner reckoning up the bill.

If the battery allowance of vehicle to be charged is less than 30%, then this vehicle directly enters charged state, stops charging after Vehicular charging is full of and send out to the car owner reckoning up the bill.

At this moment the quota number of system spare is N ', electric charging controlling box is divided into three groups of wheel current charges that carry out every 1 hour with remaining vehicle, i.e. wherein first group of relatively regularly charging in a hour, second group continually at two state transformations of charging/wait, the 3rd group is in the state of always waiting for, more than three groups of vehicles every 1 hour by turns once, realize the wheel current charge.

Electric charging controlling box is according to the continuous variation of system's quota number, the load of section transformer can constantly change, allow simultaneously the quota of Vehicular charging also in continuous variation, when the charging quota changes, remaining quota is counted N ' and is changed, wherein to be set to reduce amplitude range be 5 to the remaining quota preset range of counting N ', the increasing degree scope is 10, if remaining quota is counted the minimizing amplitude of N ' above 5, then with the allocation of quota number of instant quota number as reality, if counting the increasing degree of N ', remaining quota surpasses 10, then with the allocation of quota number of instant quota number as reality.If remaining quota is counted N ' not in default scope, then start just value-based algorithm, confirm that namely the quota number ofinitial time 1 hour charging period is that actual allocated is counted K, the actual allocated number is no longer followed the tracks of the variation of the quota number in this period, keeps the relatively stable of actual allocated number.

If electric charging controlling box breaks down with communicating by letter of power load management system, then start the minimum value algorithm, soon the minimum value of the quota number of the 1 hour period of the same period in the historical data table is as the actual allocated number.

Electric charging controlling box determines that the actual allocated of vehicle counts K, if the vehicle that withdraws from charging is arranged temporarily, then charging vehicle is settled accounts and blotter temporarily.

If in charging process, have vehicle to send to withdraw from the charging application, then to the charge lump sum of the electricity charge of this vehicle, send out to the car owner by note and to reckon up the bill.

After this group Vehicular charging isreach 1 hour, to the historical data ((minimum value of the amplitude of variation of quota number, quota number, actual allocated number, quota number in 1 hour, etc.) carry out record, and be kept at the historical data table), then three groups of vehicles are rotated translative mode, the interim clearing and the blotter that carry out the electricity charge for the charging vehicle that withdraws from temporarily simultaneously.

The above is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
