Abstract:
The present application discloses a battery equalization system, a vehicle, a battery equalization method, and a storage medium. The battery equalization system includes: a collection circuit; an equalization circuit; a controller; a charging branch circuit, connected to a charging device and a battery pack; and a first power supply branch circuit, connected to the charging device and the battery equalization system, and configured to supply power to the battery equalization system. When a state-of-charge of the battery pack is full and a cell in the battery pack needs enabling of equalization, the controller controls the charging branch circuit to disconnect, and controls the first power supply branch circuit to keep connected, so that an equalization module performs equalization processing on the cell that needs enabling of equalization.
