The battery status data includes data such as charging evaluation values, battery effective capacity rate, health, charging speed, charging efficiency, and charging times of multiple fixed energy storage batteries. After obtaining the charging evaluation values ​​of the multiple fixed energy storage batteries, the multiple charging evaluation values ​​are compared to determine the evaluation rankings of the multiple charging evaluation values.

The fixed energy storage batteries corresponding to the charging evaluation values ​​greater than the compliance evaluation values ​​are marked as compliance fixed batteries, thereby determining a plurality of compliance fixed batteries, and then counting the arranged charging numbers of the plurality of compliance fixed batteries, and superimposing the active charging numbers and the arranged charging numbers to calculate the feasible charging numbers.

[0147] The arranged energy storage charging module 104 is used to arrange energy storage charging for the plurality of fixed energy storage batteries according to the charging arrangement sequence when the active charging quantity is less than the preset standard charging quantity and the feasible charging quantity is greater than the standard charging quantity.

[0148] In an embodiment of the present invention, the arranged energy storage charging module 104 compares the active charging number and the feasible charging number with a preset standard charging number. When the active charging number is less than the standard charging number and the feasible charging number is greater than the standard charging number, an arranged charging signal is generated. At this time, according to the charging arrangement order, multiple arranged charging batteries are updated in real time from multiple qualified fixed batteries, and then arranged energy storage charging is performed on the multiple arranged charging batteries according to the arranged charging signal, thereby realizing a combination with the battery charging of the actively charged electric vehicle, expanding the management range of the energy storage battery, and improving the balancing technical effect of the battery management.

[0150] In an embodiment of the present invention, the passive active charging module 105 compares the active charging number and the feasible charging number with the preset standard charging number. When both the active charging number and the feasible charging number are less than the standard charging number, an arrangement charging signal and a broadcast charging signal are generated. According to the arrangement charging signal, energy storage charging is arranged to multiple fixed batteries that meet the standards. At the same time, according to the broadcast charging signal, positioning feedback data of multiple cooperative electric vehicles are obtained. By analyzing the multiple positioning feedback data, the multiple positioning feedback data are compared with the preset standard broadcast range, and the cooperative electric vehicles whose positioning feedback data are within the standard broadcast range are marked as target electric vehicles, thereby determining multiple target electric vehicles, and then generating active charging information. The active charging information is broadcast to multiple target electric vehicles, promoting multiple target electric vehicles to enter the target energy storage power station for vehicle battery charging. Further combined with the battery charging of electric vehicles, more reasonable and effective energy storage battery management is carried out, breaking the limited and closed scope of battery management, and further improving the balancing technical effect of battery management.
