Analysis of Typical Electric Vehicle Charging Energy Flow Technology in Extreme Environments

With the rapid development of pure electric vehicles, the importance of vehicle thermal management technology is increasing. Unlike traditional vehicles, due to the high thermal efficiency of the motor, it does not generate a large amount of heat when driving the vehicle normally like the engine. Therefore, the thermal management of pure electric vehicles is different from that of traditional fuel vehicles. In order to study the charging thermal management technology of an imported pure electric vehicle in the ultra-low and high temperature, this paper designs an experimental method based on energy flow testing analysis, explores the vehicle charging technology, and obtains the thermal management parameter threshold values of the vehicle at different temperatures through analysis, providing reference for the thermal management technology of domestic pure electric vehicles.
