电动汽车充电站电气系统设计

Design of Electrical Systems for Electric Vehicle Charging Station

电动汽车充电基础设施建设是电动汽车产业快速发展的重要前提和有力保障。以某户外电动汽车充电站为例,研究并分析了该充电站电气系统设计的要点,主要包括充电站的使用功能及设置、负荷等级确定与负荷计算、箱式变压器高低压配电系统、充电站内配电与照明系统、防雷与接地系统、安防监控系统等部分,以期为设计与运维人员提供参考。

The construction of electric vehicle charging infrastructure is an important prerequisite and strong guarantee for the rapid development of electric vehicle industry.Based on an outdoor electric vehicle charging station,the electrical design program is analyzed in this paper,which includes operation functions and settings,load level determination and calculation,high voltage and low voltage distribution in box-type transformers,internal power distribution and lighting systems,lightning protection and grounding systems,as well as security monitoring system.This paper aims to provide some references for relevant designers and maintainers.
