Wireless Charging of Electric Vehicles

Abstract Wireless power transfer (WPT) is one of the hottest topics being actively studied, and it is being widely commercialized. In particular, there has been a rapid expansion of WPT in mobile phone chargers, stationary charging electric vehicles (EVs), and dynamic charging EVs, also called road-powered EVs (RPEVs). It is expected that WPT industry will grow persistently in the coming decades. In this chapter, the concepts and practical applications of WPT to EVs are introduced. Inductive power transfer (IPT) for stationary and dynamic charging EVs is explained in detail. Design examples with experimental verifications are provided to help beginners of IPT to develop their own IPT products for EVs.
