Design and Modeling of V2G Inductive Charging System for Light-Duty Electric Vehicles

Vehicle-to-Grid (V2G) is an emerging technology resulting from the emergence of Electric Vehicles (EVs) and Renewable Energy Sources (RES). The energy stored in battery packs of EVs are a solution to the intermittency of RES. Therefore, design and control design of charging infrastructure for EVs are of high importance for the development of V2G. This paper presents a wireless charging infrastructure based on Inductive Power Transfer (IPT) for semi-fast charging of light-duty (LD) EVs. The Power Electronic Converters (PECs) and the applied control strategies are modelled by using MATLAB/Simulink. Simulation results show that G2V and V2G are feasible with the proposed charging system, with an overall efficiency of 92%.
