  • Method, system and device for active balance control of battery pack
    Patent number: 11316212
    Abstract: A method, system and device for active balance control of a battery pack are disclosed. The method includes: calculating a reference balance current ratio of a battery cell to a battery pack in each batch; calculating an actual balance current ratio of the battery cell to the battery pack at each moment in any batch; allowing the actual balance current ratio to track the reference balance current ratio of the corresponding batch in real time by executing a preset tracking algorithm; and performing balance control on the battery pack according to a tracking result. The system includes a first calculation module, a second calculation module, a tracking module, and a balance control module. The device includes a memory and a processor.
