Simulation study of a magnetic coupled resonant wireless energy transfer and storage system for electric vehicles under dynamic condition

In this paper, a systematic analysis of a magnetic coupled resonant wireless energy transfer and storage (MCR-WETS) system for electric vehicles (EVs) under dynamic condition is presented. A simplified circuit of the MCR-WETS system is proposed. The mathematical model of the mutual inductance between primary and secondary coils under dynamic and misalignment condition is obtained. An accurate dynamic battery model is adopted and a battery charging system with constant current and constant voltage charging approaches is explained. Therefore, the performance of the MCR-WETS system can be simulated. The simulation results show that the presented systematic analysis method is adequate to illustrate the detailed performance of the MCR-WETS system.
