Advances of Wireless Charging Technology in Electric Vehicle

The technology of wireless power transfer(WPT) was widely researched and discussed, and it has a lot of applications, such as making wireless chargers for phones, MP3 and other portable devices. Nowadays, using WPT into electric vehicle(EV) charging becomes a hot topic. The research and applications of EV using WPT were introduced in this paper. First of all, the review of WPT research improvements and applications in EV at home and broad were given, then two main wireless power transmission technologies, inductively coupled wireless charge and magnetic resonant coupled wireless charge, were presented. The measurements of improving efficiency of EV charging were analyzed, and the effects of wireless charging on people's health and environment were also discussed; In the end, the key problems which should be solved in the future for EV wireless charging are proposed.
