Abstract

Autonomous driving technology has made significant progress in recent decades. For fully autonomous driving of an electric vehicle, the recharging process should be possible without a manually fixed connection. Wireless charging technology is a promising solution for electric vehicle recharging automation. The wireless transformer/coupler is the key component in electric vehicle wireless charging. The maximum power transfer capability and efficiency are limited by the coupler. To reach the required power level, efficiency and electromagnetic exposure to surrounding area, the coupler should be analyzed. In this paper, a coupler with assistive coils is presented and analyzed. The assistive coils perform as reactive shielding coils as well as flux concentrating coils. Finite element simulation and circuit simulation results are shown.
