Bidirectional Contactless Charging System using Li-ion battery model

Abstract

In this paper, the performance of Bidirectional Contactless Charging System (BCCS) have been assessed by an electric circuit based battery model suitable for Electric Vehicles applications. The time, C-rate and SOC dependent electric circuit parameters of charge /discharge model are calculated using a polynomial equation. The charging system along with battery model is tested by simulation for a 2kW BCCS system and is able to transfer power in both the direction. The simulation results show that, the charging scheme could effectively maintain the longetivity of EV's and can supply power during Vehicle to Grid (V2G) operations.
