Dynamic Wireless Charging of Electric Vehicles: Supercapacitor Integration at the Service of Energy Management Optimization

The wide deployment of electric vehicles (EVs) is mainly linked to the extensive development of charging infrastructures. Dynamic wireless power transfer (DWPT) seems to be a viable solution that deals with EV's major challenges such as autonomy. In-motion charging would improve sustainable mobility by reducing storage system weight. However, large power rates are required for such applications since energy transfer must occur quickly and must match the power requirements of various vehicles. The vehicle design, road infrastructure, and electrical network are all affected by this tendency. Power-fow smoothing is essential to eliminate pulsations generated by vehicle motion as well as power peaks caused by the WPT as part of the electrifed road system, which have an impact on the total electrical load. In this paper, we present an optimal energy management scheme for the supercapacitor integration in order to meet the WPT demand and reduce the pulsation caused by EV's demand.
