The power units (11A-11C) are electrically connected to form a power unit string. Each power unit (11A-11C) includes a battery module (B) and a first switch device (SW1) connected in serial. One end of the first diode (D1) is connected to one of the power units (11A-11C), and the other end thereof is connected to a first common node to form a discharge path. The first polarity switch unit (13) is electrically connected to the first common node and the power unit string, and outputs a first operating voltage (V1). The control unit (12) is electrically connected to the first switch device (SW1) and the first polarity switch unit (13) to turn on/off the first switch device (SW1) and control the output polarity of the first polarity switch unit (13).",
