Abstract
The disclosure provides a battery heating system and a control method thereof. The system includes a first switch, a second switch, a switch component, a motor, and a main controller. The first switch, the second switch, the switch component and the main controller are integrated in a same housing. The main controller is to determine, based on a state parameter of the battery pack, that the battery pack needs to be heated, and to send a battery heating request to a vehicle controller, so as to enable the vehicle controller to send a battery heating instruction to the main controller according to the battery heating request in a case where a vehicle is in a static state and the motor is not operating; and to control, based on the battery heating instruction, the first switch, the second switch and the switch component so as to heat the battery pack.
