In a first aspect, an embodiment of the present application provides a charging method, where the method is applied to a charging device, where the charging device may be deployed in the charging apparatus 101 in fig. 1. The following describes a data processing procedure provided in the embodiment of the present application.
Fig. 2 is a schematic flow chart of an alternative charging method, which is used for charging a rechargeable battery according to an embodiment of the present application.
It should be noted that, the embodiment of the present application does not limit a specific charging scenario, and may be configured according to actual requirements.
For example, the charging method provided by the embodiment of the application can be used for charging the rechargeable battery on the electric automobile, also can be used for charging the rechargeable battery on the electric motorcycle and other equipment, and of course, can also be used for charging the rechargeable battery on other equipment, which are not listed here.
Specifically, the charging method may include, but is not limited to, S201 to S203 shown in fig. 2.
S201, the charging equipment detects the battery temperature of the rechargeable battery in the current environment.
In a possible implementation, S201 may be implemented in such a way that the charging device directly detects the battery temperature of the rechargeable battery in the current environment through the temperature sensor.
In another possible embodiment, S201 may be implemented in such a manner that the charging device detects a relevant parameter (e.g., resistance value, etc.) of the thermosensitive element, and calculates the battery temperature of the rechargeable battery in the current environment from the relevant parameter of the thermosensitive element.
S202, the charging equipment judges whether the battery temperature is less than or equal to a first temperature threshold.
The first temperature threshold value is a critical value indicating whether or not the rechargeable battery can be charged according to a direct current (rated current).
The embodiment of the application does not limit the specific value of the first temperature threshold, and can be configured according to actual requirements.
S202 may be implemented in that the charging device determines whether the battery temperature of the rechargeable battery in the current environment is less than or equal to a first temperature threshold. Specifically, if the charging device determines that the battery temperature is less than or equal to the first temperature threshold, the charging device characterizes that the battery can be charged in a direct-current high-current mode, and if the charging device determines that the battery temperature is greater than the first temperature threshold, the charging device characterizes that the battery cannot be charged in a direct-current high-current mode.
And S203, in the case that the battery temperature is less than or equal to the first temperature threshold, the charging equipment adopts a pulse charging mode to pulse charge the rechargeable battery.
S203 may be implemented such that the charging device pulse-charges the rechargeable battery in a pulse charging mode in a case where the battery temperature is less than or equal to the first temperature threshold. In the pulse charging mode, the charging device performs high-frequency alternating-current pulse charging of the rechargeable battery.
The embodiment of the application does not limit specific charging frequency and charging current in the pulse charging mode, and can be configured according to actual requirements.
The data processing scheme provided by the embodiment of the application comprises the steps of detecting the battery temperature of the rechargeable battery in the current environment, judging whether the battery temperature is smaller than or equal to a first temperature threshold value, and carrying out pulse charging on the rechargeable battery by adopting a pulse charging mode under the condition that the battery temperature is smaller than or equal to the first temperature threshold value. According to the scheme, on one hand, after lithium intercalation occurs in the battery cell cathode under high-frequency alternating current pulse, lithium is instantaneously discharged and removed, and the bearable current amplitude is increased along with the increase of frequency, so that the service life of the battery in a pulse charging mode can be ensured, and on the other hand, the charging time of pulse charging is shorter, and the charging can be rapidly completed.
Next, a process of pulse charging the rechargeable battery in the pulse charging mode when the battery temperature is less than or equal to the first temperature threshold in S203 will be described.
Specifically, as shown in fig. 3, the charging process of the pair of rechargeable batteries may include, but is not limited to, S2031 and S2032 described below.

The embodiment of the application does not limit the specific mode of storing the reference charging parameters and the number of the reference charging parameters of the parameter information, and can be configured according to actual requirements.
For example, the parameter information may store the reference charging parameters in the form of a table or document.
The reference charging parameters refer to charging parameters which need to be configured when the rechargeable battery is subjected to pulse charging in a pulse charging mode.
The embodiment of the application does not limit the type of the specific charging parameters included in the reference charging parameters, and can be configured according to actual requirements.
In one possible embodiment, the reference charging parameters may include a charging rate, a charging time, and a rest time.
In another possible embodiment, the reference charging parameters may include a charging rate and a charging frequency.
S2031 may be implemented such that the charging apparatus searches for a reference charging parameter corresponding to a battery temperature of the rechargeable battery in the current environment among the plurality of sets of reference charging parameters included in the parameter information.
Example 1, parameter information may be as shown in table 1 below.
Table 1 parameter information example
| R | T1 (second) | T2 (second) |
| -20°C | 10 | 10 | 10 |
| -15°C | 8 | 5 | 10 |
| -10°C | 5 | 5 | 15 |
| ...... | ...... | ...... | ...... |
In table 1, R represents a charging rate, t1 represents a charging time, and t2 represents a rest time.
And S2032, the charging equipment carries out pulse charging on the rechargeable battery based on the reference charging parameters corresponding to the battery temperature.
S2032 may be implemented such that the charging apparatus configures a charging parameter in a pulse charging mode based on a reference charging parameter corresponding to the battery temperature, and then pulse charges the rechargeable battery in the pulse charging mode.
Next, reference charging parameters are explained.
The reference charging parameters may include, but are not limited to, specifically the following manner a or manner B.
The mode A and the reference charging parameters comprise a charging multiplying power, a charging time and a standing time.
The mode B and the reference charging parameters comprise a charging multiplying power and a charging frequency.
In mode a, the charging rate is used to define the magnitude of the charging current in the pulse charging mode.
For example, if r=5, it means a current in which the charging current is 5 times the battery capacity.
And the charging time is used for limiting the charging duration in one pulse charging period in the pulse charging mode.
And the standing time is used for limiting the standing time length in one pulse charging period in the pulse charging mode.
The standing time is a time when charging is not performed.
Next, a process in which the charging apparatus pulse-charges the rechargeable battery based on the reference charging parameter corresponding to the battery temperature in S2032 will be described.
Taking as an example that the reference charging parameters include a charging rate, a charging time, and a rest time, as shown in fig. 4, S2032 may include, but is not limited to, S20321 to S20323 described below.
S20321, the charging apparatus configures the charging current of the pulse charging with reference to the charging magnification.
Illustratively, S20321 may be implemented where the charging apparatus references a charging rate, configures a charging current of the pulse charging to be a product of the charging rate and a battery capacity size.
And S20322, the charging equipment configures the pulse charging period of the pulse charging.
The pulse charging period includes a charging time and a rest time.
The charging device configures a charging time length parameter of a pulse charging period of pulse charging as the charging time, configures a non-charging time length (also can be an interval time length) parameter of the pulse charging period of pulse charging as the standing time, and forms a pulse charging period with one standing.
And S20323, the charging equipment performs pulse charging on the rechargeable battery according to the charging current and the pulse charging period.
S20323 may be implemented such that the charging apparatus performs periodic (pulse charging period) pulse charging of the rechargeable battery with the charging current.
The charging method provided by the embodiment of the application can also comprise a parameter information acquisition process. In the following, a description will be given of a procedure of how to obtain a set of reference charging parameters in the parameter information, taking the first temperature as an example.
As shown in fig. 5, the process may include, but is not limited to, S501 to S504 described below.
S501, the charging device detects a first charging rate under a first pulse charging period under the condition that the rechargeable battery is at a first temperature.
The first pulse charging period includes a first charging time and a first rest time.
The first temperature is any temperature. The specific value of the first temperature is not limited in the embodiment of the application, and the configuration can be carried out according to actual requirements.
S501 may be implemented in that the charging device detects a maximum safe charging rate under a first pulse charging period as a first charging rate in a case where the rechargeable battery is at a first temperature.
S502, the charging equipment detects a second charging rate under a second pulse charging period under the condition that the rechargeable battery is at the first temperature.
The second pulse charging period includes a second charging time and a second rest time.
Wherein the second pulse charging period is different from the first pulse charging period. Specifically, the first rest time and the second rest time cannot be completely the same between the first charging time and the second charging time.
S502 may be implemented such that the charging device detects a maximum safe charging rate under the second pulse charging period as the second charging rate in a case where the rechargeable battery is at the first temperature.
S503, the charging device detects a third charging rate under a third pulse charging period when the rechargeable battery is at the first temperature.
The third pulse charging period includes a third charging time and a third rest time.
The third pulse charging period is different from the first pulse charging period and the second pulse charging period respectively. Specifically, the third standing time and the second standing time cannot be completely the same between the third charging time and the second charging time, and the third standing time and the first standing time cannot be completely the same between the third charging time and the first charging time.
S503 may be implemented such that the charging device detects a maximum safe charging rate under the third pulse charging period as the third charging rate in a case where the rechargeable battery is at the first temperature.
S504, if the first value corresponding to the first pulse period is greater than the first value corresponding to the second pulse period, and the first value corresponding to the first pulse period is also greater than the first value corresponding to the third pulse period, the charging device determines the charging parameter under the first pulse period as the reference charging parameter corresponding to the first temperature in the reference information.
The first value is the product of the charging multiplying power and the charging time ratio.
The charge time ratio is the ratio of the charge time to the pulse charge period. The pulse charging period is the sum of the charging time and the rest time.
S504 may be implemented in such a manner that if the first value corresponding to the first pulse period is the maximum value of the three first values (the first value corresponding to the first pulse period, the first value corresponding to the second pulse period, and the first value corresponding to the third pulse period), the charging device determines the charging parameter under the first pulse period as the reference charging parameter corresponding to the first temperature in the reference information.
It should be noted that, when determining the reference charging parameter corresponding to the first temperature, the reference charging parameter may be the maximum value in the first values corresponding to the three pulse periods, or may be the maximum value in the first values corresponding to more pulse periods.
As shown in fig. 6, the charging method provided by the embodiment of the present application may further include S204 described below.
And S204, under the condition that the battery temperature is greater than the first temperature threshold, the charging equipment adopts a direct current charging mode to carry out direct current charging on the rechargeable battery.
S204 may be implemented in such a manner that the charging device performs dc charging on the rechargeable battery in a dc charging mode in a case where the battery temperature in the current environment of the rechargeable battery is greater than the first temperature threshold. Under the direct current charging model, the charging device charges the rechargeable battery with direct current (rated current).
The charging method provided by the embodiment of the application further comprises the steps of detecting the battery temperature of the rechargeable battery in the current environment again after a first preset time, judging whether the battery temperature is smaller than or equal to a first temperature threshold value, carrying out pulse charging on the rechargeable battery by adopting a pulse charging mode when the battery temperature is smaller than or equal to the first temperature threshold value, and carrying out direct current charging on the rechargeable battery by adopting a direct current charging mode when the battery temperature is larger than the first temperature threshold value.
Wherein the first preset time is greater than or equal to one pulse charging period.
The embodiment of the application does not limit the specific value of the first preset time, and can be configured according to actual requirements.
The first preset time may be, for example, 10 seconds.
In this way, the battery temperature of the rechargeable battery can be periodically detected, and then a charging model suitable for the temperature is adjusted based on the battery temperature, thereby further improving the charging efficiency.
The charging method provided by the embodiment of the application is described below by taking an electric automobile as an example.
Because the battery is limited in performance under a low-temperature environment and cannot be charged and discharged with large current, the electric automobile has the problem of long charging time in winter.
The charging scheme of the related technology under the low-temperature environment is that the PTC thermosensitive element is heated by discharging small current of the battery, the cooling liquid is heated by the PTC element, the temperature of the cooling liquid is gradually increased, the battery is heated by the cooling liquid, and the high-current charging is started after the temperature of the battery reaches a higher temperature.
It can be seen that in the charging process, the temperature rise time of the battery is long, the charging waiting time is long, and the total charging time is long.
In the embodiment of the application, for the requirement that a user hopes to shorten the charging time, pulse high-current charging is adopted in a low-temperature environment, so that the aim of shortening the low-temperature charging time is fulfilled, the temperature of the battery is quickly raised to a proper working temperature, and normal high-current direct-current charging is realized.
The scheme of this embodiment will be specifically described below.
When the battery is charged by high-rate direct current, the battery cell cathode cannot quickly complete lithium intercalation, so that the cathode is hyperpolarized to separate out lithium, the capacity of the battery is attenuated, and the service life of the battery is reduced. However, under the high-frequency alternating current pulse, the lithium is removed by discharging instantly after the negative electrode of the battery cell is charged and intercalated. In this way, the magnitude of the current that the battery can withstand (which may also be referred to as the current rate or simply rate) increases with increasing frequency.
Fig. 7 illustrates the relationship between the magnitude of current and frequency that a battery can withstand at different temperatures.
It can be seen from fig. 7 that the current amplitude (multiplying power) that the battery can withstand increases with increasing frequency (from low to medium to high) in high, medium and low temperature environments, and that the change is more pronounced in low temperature environments.
Based on this, this embodiment of the present application proposes a method that can shorten charging in a low-temperature environment. A specific principle may include that Q represents the amount of electricity, I represents the current, and t represents the charging time, according to q=it. In one charging period S, R high-rate instantaneous charging is adopted in t1 time, and after standing for t2 time, the next charging period is entered, so that in one S period, the capacity value Q1 obtained by an instantaneous power-on mode (also can be a pulse charging mode) is larger than the electric quantity Q2 charged in a small-current charging mode in t1+t2 time.
Therefore, the instantaneous power-on mode charges more electricity in the battery in unit time, and compared with the conventional direct-current charging mode, the total time is reduced, and the waiting time of a user is shortened.
The pulse current only takes the charging current, a certain standing time is still needed in the battery core, the lithium ion is embedded, a proper ratio of charging to standing time is found, and the shortest charging time can be obtained by combining the charging multiplying power.
Specifically, the method can include, but is not limited to, the following steps one to three.
Step one, obtaining the ratio k (equivalent to the charging time ratio) of the charging and pulse period which can fully react in the battery cell under different temperatures and different frequencies through a battery cell calibration mode.
Wherein the value of k can be described by the following formula (1).
K=t1/(t1+t2) formula (1);
in the formula (1), t1 represents a charging time, and t2 represents a rest time.
As can be seen from equation (1), k values at different temperatures are obtained, i.e. corresponding t1 and t2 are obtained.
Firstly, measuring the safe pulse charging multiplying power R corresponding to different periods t1+t2 at a certain specific temperature, and taking the maximum value of R multiplied by t 1/(t1+t2) as the optimal parameter at the temperature point.
For example, the charging rate R for the safety pulse corresponding to different charging periods t1+t2 in a-20 ℃ environment can be shown in the following table 2.
Table 2-examples of charging rates corresponding to different charging periods in a 20 ℃ environment
Then, the optimum value of Rxt 1/(t1+t2) at a plurality of temperature points was measured, and a MAP table (corresponding to parameter information) was formed.
Table 3MAP table example
| R | t1 | t2 |
| -20°C | R-20 | t1-20 | t2-20 |
| -15°C | R-15 | t1-15 | t2-15 |
| -10°C | R-10 | t1-10 | t2-10 |
| ...... | ...... | ...... | ...... |
And step two, a pulse charging mode is added to the Battery charging, the data in the step one is formed into a MAP table, the MAP table is embedded into a Battery management system (Battery MANAGEMENT SYSTEM, BMS) software algorithm, and when the Battery temperature is lower than a temperature threshold value X, the pulse charging mode is set.
And thirdly, charging by adopting a special charging pile.
Compared with a conventional charging pile, the charging pile is additionally provided with a Pulse charging mode, and in the Pulse charging mode, charging is performed through a Pulse Current (PC). When the normal connection with battery charging is detected, temperature judgment is carried out through a controller area network (Controller Area Network, CAN) bus, and the charging mode is judged to be firstly entered.
As shown in fig. 8, the special charging pile 80 includes a Direct Current (DC) charging module 801, a Pulse Current (PC) charging module 802, a charging pile controller 803, and a battery 804 of the electric vehicle.
The inlets of the direct current charging module 801 and the pulse charging module 802 are connected with the mains supply, and the outlets are connected with the battery 804 of the electric automobile.
One end of the charging pile controller 803 is connected with the direct current charging module 801 and the pulse charging module 802, and the other end is connected with a battery 804 of the electric vehicle. The charging pile controller 803 is configured to perform temperature determination through the CAN bus, and control the dc charging module 801 or the pulse charging module 802 to charge the battery 804 of the electric vehicle based on the determination result.
Next, a charging process will be described. As shown in fig. 9, the process may include, but is not limited to, S901 to S905 described below.
And S901, the battery charging connection is normal.
S902, detecting whether the battery temperature is greater than a first temperature threshold.
If the battery temperature is greater than the first temperature threshold, S903 described below is performed, and if the battery temperature is not greater than the first temperature threshold, S904 described below is performed.
S903, charging by adopting a direct current charging mode.
S904, charging by adopting a pulse charging mode.
S905, obtaining the current optimal pulse charging coefficient by looking up a table, and outputting pulse current.
After the first preset time, S902 is re-executed.
In the low-temperature charging scene, when the battery temperature is lower than the temperature threshold value X, looking up a table can look up the maximum value of R multiplied by t 1/(t1+t2) under the current temperature condition, and taking the parameter corresponding to the maximum value as the optimal coefficient of the current pulse charging, so that the pulse charging is performed.
Under a certain low-temperature environment, the R multiplying power current amplitude is adopted, the unit charging time t=t1/(t1+t2), if R×t1/(t1+t2) >1, the charging quantity in the unit time is larger than the charging quantity in the conventional direct current T time, and the time consumption T' in the low-temperature charging stage is obviously shortened than the time consumption T in the conventional charging mode. Therefore, on one hand, more electric quantity of the battery can be charged, on the other hand, the heat generation is increased due to the increase of the current, the temperature is quickly increased to reach a proper working temperature, the direct current high-current charging can be realized, and the total charging time is shortened.
Fig. 10 illustrates a comparison of conventional dc charging and pulse charging.
In fig. 10, the dashed line represents the current value, R-C represents charging by pulse charging, T1 represents the charging time T2 represents the rest time, T 'represents the total charging time in the pulse charging mode, and the total time consumption T in the conventional dc charging mode is shown as T' being smaller than T, i.e., the time consumption of pulse charging is shorter than that of conventional dc charging.
