交直流一体电动汽车充电站模拟试验平台设计

Design of Simulation Test Platform for AC and DC Electric Vehicle Charging Station

基于对现有电动汽车充电站拓扑结构以及慢充、快充、电池快速更换三种电能补给方式的分析,设计了一种交流与直流母线供电系统共存,兼顾三种电能补给方式的电动汽车充换电站试验平台,包括谐波治理、直流母线供电、交流母线供电、锂离子蓄电池等部分。平台可以对交、直流供电系统的电能利用效率进行比较,并且能够作为一个储能系统展开相关研究。

Based on analysis of the topology of existing electric vehicle charging stations and three kinds of power supply modes, namely slow charge, fast charge and battery quick change, this paper designs a test platform for electric car purging power station with AC and DC bus power supply system and three kinds of power supply modes. The platform includes harmonic management, DC bus power supply, communication bus power supply, lithium ion battery and so on. The platform not only can compare the electrical energy efficiency of AC power supply system to that of DC power supply system, but also can be used as an energy storage system for further research.
