New energy automobile power battery temperature regulation control device and method

Abstract

The invention relates to a new energy automobile power battery temperature regulation control device and method. The control device is located in the battery management system and is composed of a data acquisition module, a state judgment module, a temperature adjustment module, a fault processing module and an information interaction module. The system can effectively collect power battery information, judge the state of the power battery, adjust the temperature of the power battery, process the fault working condition of the whole vehicle, and transmit and interact the whole vehicle information to a big data platform and a user mobile terminal, thereby realizing remote operation of new energy vehicle power battery temperature adjustment control, and improving the performance of the power battery. And the power output requirement of a user on the whole vehicle under high-low temperature conditions is met. According to the method, the temperature of the power battery is effectively adjusted and controlled under the high-low temperature environment or the harsh working condition of the whole vehicle, it is guaranteed that the power battery works at the proper temperature, stable driving of the whole vehicle is facilitated, the safety and stability of a new energy system are improved, new energy vehicles are assisted to compete in the market, and the market competitiveness is improved. And the national green development strategy is effectively promoted.
