电动汽车充电机性能评价指标体系研究

Research on performance evaluation of electric vehicle chargers

电动汽车充电机的性能评价是维持充电机良好的工作状态的重要环节。通过对充电机电气性能、安全性能、经济性能、环境性能及电磁兼容性能进行分析,对其相应的指标进行筛选处理,建立了一种基于层次分析法和模糊综合评判法的集成的电动汽车充电机性能评价体系。利用该体系对充电机进行性能评价,并量化评价结果,为判别充电机的性能状态提供依据。实例分析表明,提出的方法简洁,易操作,可以有效地评估充电机的性能状态。

The performance evaluation of electric vehicle chargers is an important part for maintaining its good working state. By analyzing electrical and safety performance, economical and environmental performance, and electromagnet- ic compatibility performance of electric vehicle chargers, and dealing with theirs corresponding indexes, the perform- ance evaluation system of electric vehicle chargers was presented. The presented system was built based on a method, so - called the integration of analytic hierarchy process （AHP） and fuzzy comprehensive evaluation method. The per- formance of electric vehicle chargers can be evaluated by using the presented system. And the quantitative evaluation results can provide the basis for determining the performance status of electric vehicle chargers. The practical opera- tional results have shown that the proposed assessment model and method are simple and easy to operate, and they can effectively evaluate the performance status of electric vehicle chargers and quantify results.
