ABSTRACT

Wireless power transfer is a popular charging method for future EVs. However, it is difficult for alignment because receive coil is usually placed at the bottom of vehicles and it is hard to get its exact location when charging. Therefore, to make receive coil visible and convenient for alignment, wheely coil has been proposed that can be embedded in the wheel hub. Half scale model has been analyzed in this paper. Experiment results show that it can achieve transfer efficiency of 85.13% when transfer distance is 50 mm.
