A battery self-heating device includes a battery self-heating circuit and a controller. The battery self-heating circuit includes a first battery group, a second battery group, a bridge arm, and a winding corresponding to the bridge arm. A negative electrode of the first battery group and a positive electrode of the second battery group are connected to each other, and are connected to an output end of the winding. An input end of the winding is connected to a midpoint of the bridge arm. A positive electrode of the first battery group is connected to a first bus end of the bridge arm. A negative electrode of the second battery group is connected to a second bus end of the bridge arm. The controller is configured to adjust the duty ratio of the bridge arm according to a target duty ratio range.
