Hybrid Assessment Method for Health Status of Charging piles Based on AHP and Entropy Weighting

As the new energy vehicle industry continues to rapidly develop and supporting charging facilities continue to improve, the operation of a large number of decentralized and centralized charging stations has become increasingly prominent. In order to scientifically manage and comprehensively evaluate existing charging stations, this paper conducts a comprehensive analysis of the technical performance requirements and safety impact factors of electric vehicle charging stations. From the perspectives of electrical performance and safety performance, indicators are selected and determined, and a hierarchical structure of indicators is constructed for the comprehensive evaluation of the health status of electric vehicle charging stations. A comprehensive evaluation model of the health status of electric vehicle charging stations is then constructed based on the uncertain analytic hierarchy process and entropy weight method. Finally, the comprehensive evaluation model and algorithm for the health status of charging stations are validated and compared through specific examples, achieving efficient evaluation of the health status of charging piles.
