摘要：

Short cruise range is one of the major limitations of electric vehicles. To address this problem，dynamic wireless power transfer has been proposed. However, the eddy current loss in foreign matter is one of the greatest disadvantages of dynamic wireless power transfer. Eddy current loss decreases efficiency of wireless power transfer and increases temperature of the foreign matter, which causes burning of of the combustible materials around the foreign matter in the worst case. Herein we propose a wireless power transfer system named in-wheel coil wherein the magnetic flus in concentrated in the tires and wheels. In addition, we propose suitable materials for the tires and the wheels of the system, to reduce the eddy current loss, are proposed using actual measurement data. © 2021 The Institute of Electrical Engineers of Japan.
