The present disclosure provides a battery heating system and a control method thereof. The present disclosure relates to the field of battery power. The battery heating system includes a main positive switch (K1), a main negative switch (K2), an inverter (P2), a motor (P3), and a battery management unit. The inverter (P2) includes a first phase bridge arm, a second phase bridge arm and a third phase bridge arm connected in parallel. A motor controller (P20) in the inverter (P2) is configured to output a drive signal to a target upper-bridge-arm switch unit and a target lower-bridge-arm switch unit, so as to control a switch unit of an upper bridge arm of any one of three phase bridge arms and a switch unit of a lower bridge arm of at least one of the bridge arms except the bridge arm where the target upper-bridge-arm switch unit is located to be periodically turned on and off. The battery management unit (P4) is configured to collect state parameters of the battery pack (P1). When the state parameters of the battery pack (P1) meet preset heating conditions, a control signal is sent to the motor controller (P20) to control the motor controller (P20) to output the drive signal.
