Research on Comprehensive Evaluation Method of Optimized Charging

The characteristics of the power battery determine the performance of the electric vehicle, and the charging time of the power battery is much longer than the traditional fuel vehicle, which has become one of the key factors limiting the development of the electric vehicle. At present, the research focuses on improving the traditional Constant Current Constant Voltage charging method and pulse charging method by optimal charging of power batteries, and few studies have been done on the evaluation of charging methods. Therefore, this paper evaluates the performance of the proposed optimal charging method from three aspects: polarization voltage characteristics, charging efficiency and charging temperature rise. The verification results show that these three optimized charging methods have better performance than the traditional charging methods.
