Wheel Insulation for Via- Wheel Power Transfer Structure

Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a wheel insulated via-wheel power transfer structure for electric vehicle on electrified roadway. The structure is composed of wheel insulation mechanism and drum collector mechanism. Wheel insulation mechanism is made of a two-piece wheel that has a rim and a disc. The rim is made from aluminum and the disc is made from glass fiber reinforced plastics. Drum collector mechanism has an electrode that is shape to go around a drum brake. Power received from the electrified road to the rim is transmitted to the in-vehicle circuit by drum collector mechanism using electric field coupling between the rim and an electrode. Wheel insulation mechanism insulates the rim and the metal body at high frequency by the disc, and mitigates power loss in the metal body. We implemented wheel insulation mechanism and drum collector mechanism into a small electric vehicle. The maximum effective transmission efficiency calculated from the measured S parameter of the via-wheel power transfer with the structure mounted reaches 92.8 %.
