The working principle of active equalization is to transfer energy instead of excess power loss. When a certain voltage difference occurs in the battery, the BMS starts the equalization control, and the high-voltage battery transfers energy to the low-voltage battery to increase the voltage of the low-voltage battery cell.Compared with passive equalization, active equalization has the advantages of high energy use efficiency and low heat generation during equalization.

The main function of this battery management system is to protect the cells of lithium batteries and maintain the safety and stability of the battery during charging and discharging. It plays an important role in the performance of the entire battery circuit system.
