and the charging selection module is used for determining the battery module to be charged based on the SOC value of each battery module in the same battery pack and sending a charging instruction to the switch matrix.
It can be understood that, in the system of the embodiment of the present invention, the core logic is that the central controller obtains the state of each battery module in each battery pack, and then sends the information to the control charging selection module, the charging selection module is responsible for controlling the switch matrix of each corresponding battery pack, and the switch matrix is responsible for conducting the charging loop of the battery module in the battery pack; on the other hand, the central controller also participates in controlling the direct current output of the plurality of direct current pulse sources, so that the direct current output is variable.
It is understood that the number of the battery packs in the embodiment of the present invention has at least two sets, because in the embodiment of the present invention, the dc pulse source and the switch matrix have a one-to-one correspondence relationship with the battery packs, respectively; when the number of the battery packs is more than 1, the switch matrix is favorable for realizing complex logic control, so that the charging loop of each battery module in the battery pack is controlled. And based on the control of a plurality of direct current pulse sources, the current output with different sizes can be realized, and various output current requirements are met.

It can be understood that, in the embodiment of the present invention, the charging selection module determines the battery module to be charged by using an equalization control algorithm, and fig. 3 shows a specific flow of the equalization control algorithm in an implementation manner of the embodiment of the present invention, where the specific flow includes:
