Abstract:

As one of contactless electric power transfer technologies for electric-vehicle (EV) charging,
the Wireless Charging Technology (WCT) has the highlights of high safety, intelligent operation, flexible
configurations, etc. This paper reviewed the technical architecture, categories and features for EV WCT. The
state-of-art of several hot issues were summarized, including power electronic topologies, coupler structures,
power transfer levels, modeling approaches, biosafety, etc., and practical achievements of the relative
automotive enterprises and laboratories were also concluded. The future technical developing trends for this
technology include the innovation and optimization of power electronics topologies and control algorithms, the
biosafety and the utilization of new materials, etc., and the applicative trends cover the on-line wireless charging,
assistant driving, V2X((Vehicle-to-Grid, V2G), (Vehicle-to-Home, V2H), etc.) bidirectional power transfer, etc.
