Summary: | A battery heating device comprises a controller, a power battery, a target winding and a target bridge arm. The power battery comprises a first battery module and a second battery module. A first end of the target winding is connected to a negative electrode of the first battery module and a positive electrode of the second battery module, and a second end of the target winding is connected to the midpoint of the target bridge arm. A first end of the target bridge arm is connected to a positive electrode of the first battery module, and a second end of the target bridge arm is connected to a negative electrode of the second battery module. The controller is connected to the target bridge arm, and is configured to: control, in a parking heating mode, the target bridge arm to cause the first battery module and the second battery module to charge and discharge alternately, thereby heating the power battery.
