A battery self-heating device, comprising: a bridge arm converter, an energy storage element, an inductor and a controller. The controller is configured to control, in a preset state, the connection and disconnection of the bridge arm converter, such that a first power battery and a second power battery are respectively charged/discharged by means of the inductor, and each form a freewheeling circuit by means of the energy storage element, so as to realize the continuous heating of the first power battery and the second power battery.
