A Review on Dynamic Wireless Charging Systems

The increasing diffusion of Electric Vehicles (EVs) is driving academic and institutional research towards exploring different possible ways of charging vehicles in a fast, reliable and safe way. For this reason, Wireless Power Transfer (WPT) systems have recently been receiving a lot of attention in the academic literature. In particular, the Dynamic Wireless Charging (DWC) system is subject of the research of many teams because it gives to the vehicles the possibility to increase their driving range and decrease their battery size, which are the main problems of the EVs. This work reviews the two main structure used for the exchange of the power, the lumped and the stretched track. Furthermore, the main drawbacks and advantages of these two solutions are highlighted and a feasible application of them is discussed.
