Abstract

In the experimental study of electric vehicle (EV) charging equipment performance testing, we found that when the EV charging equipment charged the power battery in a constant current mode, some charging devices output current contained a lot of current ripples. Thus, the index of voltage ripple coefficient had not been able to evaluate the charging performance of charging equipment accurately and comprehensively. In reaction to the phenomenon, this paper quantified the impact of the current ripples on the conversion efficiency, the security and the reliability of the charging equipment through theoretical analysis, simulation and experimental verification, and the results showed that the current ripples have important influence on chargers. Based on the research results, this paper suggested that bringing the technical index of current ripple coefficient into the technical specification of EV charging equipment.
