Abstract

The dynamic charging for electric vehicles (EVs), compared with stationary charging, has become an essential research direction for release users from long parking time. In this paper, the coupling theories of coils are analyzed in aspects of shapes, misalignment. The considerations of coils and ferrites when designing the dynamic wireless charging system for EVs are indicated by simulation results. A wireless charging platform based on inductive coupled power transmission is presented, and the analyses are proved in hardware. The power efficiency of the proposed system is up to 82.29% after improvement.
