The variable weights analysis method was used to evaluate the charging equipment performance. A comprehensive evaluation index system for EV charging equipment performance was established. And the method for indexes to get evaluated value and to be quantified uniformly was discussed, which was followed by principle and procedure of weight calculation by using variable weight analysis method. Finally, a software was designed to analyze and evaluate the test data, and the software was used to analyze the test data of two chargers, and then, the final result was obtained by using variable weight analysis method. The analysis results have shown that variable weight analysis method can be used efficiently to evaluate EV charging equipment performance, and the results highlight the role of the weak part, making the evaluation more reasonable. This method can not only be applied to the evaluation of EV charging equipment performance, but also to the comprehensive evaluation of other complex systems.
