The disclosure provides a battery heating system and a control method thereof. The system includes a first switch (K1) connected to a positive electrode of the battery pack (E), a second switch (K2) connected to a negative electrode of the battery pack (E), a switch component (K3) connected between the first switch (K1) and the second switch (K2), a motor (M) connected to the switch component (K3), and a main controller (P); wherein: the first switch (K1), the second switch (K2), the switch component (K3) and the main controller (P) are integrated in a same housing; the main controller (P) is configured to determine, based on a state parameter of the battery pack (E), whether the battery pack (E) needs to be heated, and to send a battery heating request to a vehicle controller when it is determined that the battery pack (E) needs to be heated, so as to enable the vehicle controller to send a battery heating instruction to the main controller (P) according to the battery heating request in a case where it is determined that a vehicle is in a static state and the motor (M) is not operating; and the main controller (P) is configured to control, based on the battery heating instruction, the first switch (K1), the second switch (K2) and the switch component (K3) so as to heat the battery pack (E). Based on the embodiments of the disclosure, cost can be reduced and heating efficiency can be improved.
