Application and Development Prospect of Wireless Charging for Electric Vehicles

Abstract

Wireless charging technology for electric vehicles (WCT) is a new non-contact charging technology applied to new energy electric vehicles. Compared with traditional contact wire charging, WCT has the advantages of high safety factor, less weather factor, more intelligent charging and convenient configuration. Firstly, this paper discusses the background of wireless charging technology for electric vehicles, the development history of wireless charging and the research status at home and abroad. Then, it summarizes the basic composition, principle, category and performance characteristics of electric vehicle wireless charging, describes the main application status and development prospects of wireless charging technology in electric vehicle, and finally analyses the 3-60 kW high-power wireless charging case of ZTEV electric vehicle which has been applied in many places in China and Qualcomm case, put forward the future prospects of wireless charging technology for automobiles.
