The eddy current loss in the steel chassis of an electric vehicle (EV) is an underestimated problem facing the EV oriented wireless charging system (WCS) designers. In this paper, we have proposed three basic optimizing strategies to develop efficient WCSs with less eddy losses. Finite element simulations are conducted to compare and evaluate the effectiveness of these three methods. Moreover, a 3-kW EV oriented wireless charging prototype is developed, with a steel plate imitating the… Expand
