EMC and EMF safety issues in wireless charging system for an electric vehicle (EV)
A numerical investigation is carried out to assess the EMC and EMF safety compliance of a wireless power transfer (WPT) system used to recharge the battery of an electric vehicle (EV). The assessment is numerically performed considering a WPT system working at the frequency of 85 kHz with output power of 7.7 kW. The prediction of the electromagnetic field is carried out by using a finite element method (FEM) code to model the WPT coils and the chassis of the car.
