A practical static simulator for dynamic wireless charging of electric vehicle using receiver open circuit voltage equivalent

This paper presents a novel electric vehicle (EV) dynamic wireless charging (DWC) research platform solution. Conventional solution tends to build a low speed, space-occupying, power-derating system, which does not accurately reflect the dynamic process of on-board wireless charger at high travelling speed. Considering the receiver-side open circuit voltage equivalent, the proposed solution simulates the motion-induced fluctuation of receiver's parameters by controlling the transmitter-side electrical parameter. In this way, a static magnetic coupler is preferred rather than a set of bulky motional one for a DWC experimental bench. Based on this idea, full power and speed scale DWC prototype can be easily realized in laboratory before the final roadway test.
