N2 - Due to various advantages, wireless charging as well as wired charging for electrical vehicles (EV) will co-exist for some time to come. A hybrid system that provides either wired or wireless charging mode is proposed in the paper. The hybrid system shares the workplaces and the power devices to save costs significantly. The cost of DC power module accounts for a large proportion of the total cost of the wired or wireless charging system and is directly related to its rated power. To reduce the rated power requirement of the DC module of the hybrid charging system, an optimized parameter design method regarding the coupling inductance of the wireless charging is presented for the hybrid system. Under the optimized coupling inductance, the minimum rated DC power requirement is achieved while meeting the battery charging profile of both the wired and wireless charging application. An EV hybrid charging system prototype is designed, built, and tested. Experiments showed that the proposed hybrid charging system has good adaptability for either charging method. Moreover, the proposed parameter design procedure can minimize the rated power requirement of the DC power module.
