The invention discloses a pure electric vehicle remote power battery heating system and a control method thereof. A remote control terminal is wirelessly connected with a remote monitoring service platform through a telecom operator network, and the remote monitoring service platform is wirelessly connected with the remote vehicle-mounted monitoring terminal through a telecom operator network. Theremote vehicle-mounted monitoring terminal, the vehicle control unit, the power battery system, the high-voltage distribution box and the DC-DC controller are all in signal connection with the CAN bus. Positive and negative electrodes of the power battery system are connected with positive and negative electrodes of a main distribution interface of the high-voltage distribution box through high-voltage cables; the positive electrode and the negative electrode of an auxiliary power distribution interface of the high-voltage power distribution box are connected with the positive electrode and the negative electrode of a vehicle-mounted 12V storage battery through theDC-DC controller. The power battery system comprises a battery management system, a heating film and a control system of the heating film. According to the design, the safety of circuit design is high, multiple protection is achieved, thermal runaway is avoided, the control strategy is reasonable, and the monitoring safety is high.
