Various wireless power transmissions (WPT) are applied to charge an electric vehicle (EV). An inductive coupling WPT and resonance coupling WPT are often used. We proposed a WPT via microwave (microwave power transmission; MPT) for the wireless charging of the EV. We, Kyoto University, developed two types of the wireless charging of the EV with microwave. One is short distance system which has been developed from 2003. A microwave transmitter put on a road or a parking place and a microwave receiver put on a body of the EV. This is similar system to an inductive coupling WPT or a resonance coupling WPT. The other is mid distance system which has been developed from 2010. There is no coupling between a transmitter and a receiver. In this paper, we describe merits and demerits of both MPT systems.
