Research On Advanced Control System Of Electric Vehicle Charging

A418 to the development of electric vehicle charging system and the characteristic which are high reliability and high intelligentiaize of charging, we put forward a method that high frequency and variable current to meet the requirement of high-power and high frequency. In the project, full bridge circuit in the rectifying process provides a theoretical method to achieve a more efficient frequency conversion and energy utilization. Based on full bridge circuit, the phase shifted soft switching control method provides the control strategy for the high quality power supply of charging system. This system reduced the charging time and improved the efficiency of charging.

I. Introduction

Electric vehicle charging equipment mainly include three kinds, that is charging pile, charging station and electrical changing station. These charging equipment corresponding to normal charge, fast charge and mechanical charge. Occident mainly use charging pile at present[1]. With a view to the complex condition of China, the electric power supply of electric vehicle mainly depend on charging pile and charging station will also support it in the future and the charging pile, the charging station and the electrical changing station will make up the electric vehicle charging system^[2]. In this paper we put forward a method that high frequency and variable current to improve the efficiency of electric vehicle charging.
