With the development of electric vehicles (EVs), the performance of the chargers has a great influence on the feeling of EVs users. This paper proposes a method based on the combination weighting method and the TOPSIS (technique for order preference by similarity to an ideal solution) method in order to evaluate the operating performance of EV chargers scientifically and reasonably. Firstly, the static and dynamic indicators of the charger performance evaluation are established. Static indicators include the output performance, safety performance, electromagnetic compatibility and other performance of EV chargers. The dynamic indicators are defined as the influence of the chargers on the power quality of the grid. Then, the combined weights are formed with the subjective and objective weights based on Game theory and all the weights are normalized. Finally, the TOPSIS method is used to score the closeness of the operating state of the charger. Three chargers chosen from Tianjin market are used as case study and the evaluation results correspond with the sales. So the proposed method can evaluate the chargers in a comprehensive way and provide a reliable suggestion for the charger consumers.
