Problems solved by technology

The performance of charging piles can be evaluated through the big data analysis of PTZ. The performance of existing charging piles is often only evaluated through simple maintenance. However, my country has a vast territory, and the climate and environment vary greatly. Charging piles have a certain impact. Therefore, the existing charging pile performance evaluation methods cannot comprehensively and effectively evaluate the performance of charging piles, with large errors and low evaluation credibility.

Abstract

The invention discloses a charging pile performance evaluation method and device based on a cloud platform. The method comprises the steps of obtaining charging pile maintenance data through the cloud platform; calculating a maintenance rate under each index according to the maintenance data; establishing a grey cloud model, and calculating membership degrees of different levels of each index; calculating a weight matrix of each index based on an AHP analytic hierarchy process; obtaining a comprehensive clustering coefficient according to the membership degrees of different levels of each index and the weight matrix; calculating a relative index state value according to the comprehensive clustering coefficient; determining a comprehensive correction rate by using a TOPSIS method according to the relative index state value; performing charging pile performance evaluation based on the comprehensive correction rate; the method can effectively improve the credibility of evaluation.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a method and device for evaluating the performance of charging piles based on a cloud platform. Background technique [0002] As the output of electric vehicles increases year by year, the scale of charging piles is also increasing. As one of the infrastructures for electric vehicles, the safety and reliability of charging piles is particularly important. At present, charging piles mainly carry out data communication and transmission through wired networks, wireless networks, etc., and use cloud platforms for data storage and processing. Cloud platforms can not only meet the storage needs of huge data volumes, but also analyze data. For example, patent document CN113285989A discloses an intelligent management method and system for electric vehicle charging stations based on the Internet of Things, which collects charging equipment, charging field environment and behavior d...
