Design of Battery Charging System for Electric Vehicle

Abstract

High power switch source converter technique that is applied to intelligent charger is presented in this paper to meet the requirement of fast and scathe less charging for the auto mobile storage batteries. As the need of charging, the total scheme of quick charging system for electric vehicle is given, and the selection of topology configuration of high power charger, the design of control circuit and protection circuit are introduced in detail Experimental results prove that the charging power can scathe lessly charge for power batteries in short time, which meet the requirement of rapid charging. The study in this paper provides reliable and effective charging equipment for novel automobile vehicle and shows good application prospect.

The power factor correction and segregation variable pressure of the way the modulation charging power supply has small volume, light weight, high reliability, high efficiency, the transformation of the power supply power grid little interference etc. Characteristics And the whole system but also increased the kinds of protect circuit measures, with the vehicle safety equipment general specification, which is of great practical application value.

Keywords: electric vehicle；BOOST converter；APFC；half bridge converter
