| 摘 要： | 为保障电动汽车充电机安全可靠运行,解决充电机性能故障难以识别的问题,论述了电动汽车充电机性能状态评估研究现状并提出一种充电机性能状态综合评估方法。首先分析现有电动汽车充电标准,构建了充电机性能评估指标体系。其次运用层次分析法和熵权法,确定指标的综合权重。然后利用模糊综合评判理论建立评价模型,实现对充电机性能状态的综合评估。最后以一台充电机为例进行性能评估分析。结果论证了所提出指标体系的有效性和评估方法的实用性,能够为制定充电设备的运行维护方案提供依据。

| Abstract: | In order to guarantee the safe and reliable operation of the electric vehicle charger,the status quo of the performance evaluation of the electric vehicle charger is reported and a comprehensive evaluation method of the performance status of the charger is proposed.Firstly,based on the analysis of the current charging standards of electric vehicles,the evaluation index system of the health status of charging equipment is constructed.Secondly,the Analytic Hierarchy Process(AHP)and the entropy method are combined to determine the comprehensive weight of the indicators.Then the fuzzy comprehensive evaluation is used to evaluate the health states of charging equipment.Finally,the above indicator system and evaluation method are used to evaluate a charger.The results show the validity of the proposed index system and the practicability of the evaluation method,which can provide a basis for the development of operation and maintenance plans for charging equipment. |
