Abstract
In this paper a circular coil for electric vehicle (EV) static wireless charging is considered. In particular, the coil geometry has been optimized in order to maximize coupling coefficient, reduce losses and thus maximizing transmission efficiency. The procedure that has been used to optimize the ferrite thicknesses to prevent the material saturation is shown and the losses introduced from the aluminum shielding are estimated. In addition, the attention was focused on magnetic fields limits in surrounding environment and on the system cost. The results obtained from finite element method (FEM) simulation have been experimentally validated.Keywords
