Abstract
This paper proposes a method to evaluate the health of electric vehicle charging equipment based on game theory combined weighting. Firstly, the evaluation indicator system of charging facility health degree is established from three aspects of electrical performance, protection device performance, and other performance. Secondly, the subjective weight of the indicator is determined by the Analytic Hierarchy Process (AHP) method, and the objective weight of the indicator is determined by the Coefficient of Variation method and the CRITIC method. On this basis, the combination weight is determined by using the idea of game theory. Finally, the combined membership function is selected to determine the membership degree of each indicator, and the evaluation of the health of charging equipment is completed by the fuzzy comprehensive evaluation model.
