Study of wireless charging lane for electric vehicles

In this paper, an inductive wireless charging lane for electric vehicles is presented. The lane proposed here consists of multiple spiral coils, which are laid down on a track. The specific parameters for the layout of the proposed lane are determined through simulation by the finite element analysis (FEA) software Maxwell. A small prototype of the wireless charging lane is constructed and experimental results show that, a modified, scaled-down model vehicle, with receiver coils attached to the bottom, can move smoothly along the lane without any external power excitation.
