Test and Research on Electric Vehicles Wireless Power Transfer System

Abstract

In order to meet requirements of testing wireless power transfer system for EVs, a test bench was developed to conduct practical performance test. And it was used to test one wireless power transfer system for EVs application. The charging characteristic, output voltage-load current characteristic, the relation between charging efficiency and load & power factor, the relation between efficiency and position of two coils were tested and analyzed basing on collected data, which will be basic preparation for conducting normal test on performance of wireless power transfer system for EVs in near future.
