    Abstract: An energy conversion device is provided, including a motor coil (11), a bridge arm converter (12), and a bidirectional bridge arm (13). The bridge arm converter (12) is separately connected to the motor coil (11) and the bidirectional bridge arm (13). The motor coil (11), the bridge arm converter (12), and the bidirectional bridge arm (13) are all connected to an external charging port (10). Both the bridge arm converter (12) and the bidirectional bridge arm (13) are connected to an external battery 200. The motor coil (11), the bridge arm converter (12), and the external charging port (10) form a DC charging circuit for charging the external battery 200. The motor coil (11), the bridge arm converter (12), the bidirectional bridge arm (13), and the external charging port (10) form an AC charging circuit for charging the external battery (200). The motor coil (11), the bridge arm converter (12), and the external battery (200) form a motor drive circuit.

    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. By improving the electrical connection structure of the battery equalization system, the present application extends the battery equalization time, improves the battery equalization effect, and resolves the technical problem of low equalization efficiency of the battery equalization system in the related art.
