Pure electric vehicle remote power battery heating system and control method thereof

Abstract

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.

Description

technical field [0001] The invention relates to a remote power battery heating system of a pure electric vehicle and a control method thereof, and is particularly suitable for improving the controllability and safety of remote heating. Background technique [0002] Electric vehicles have zero pollution and will not cause damage to the environment in which human beings live. They have also brought about huge changes to the entire energy structure, and they have also received strong support at the national level. As the popularity of electric vehicles becomes wider and wider, users have higher requirements for the requirements and performance of electric vehicles. As the core component of electric vehicles, the power battery has improved its performance with the development of technology. Due to the constraints of current technology and core materials, the low-temperature performance of the power battery has not made a major breakthrough. Especially in the low temperature con...
