An energy management framework for a PV-BESS supported grid-integrated LCC-S wireless EV charging system

This paper presents an intelligent energy management strategy (EMS) for a PV–BESS–Grid integrated dual electric vehicle (EV) charging system. To ensure optimal power sharing between PV, BESS, grid and EV loads, the proposed framework integrates an ANFIS-PI based maximum power point tracking (MPPT) controller, grid current regulation, and a rule-based EMS. To support efficient constant-current and constant-voltage charging, a dual-sided LCC-S compensated wireless power transfer topology is used. Under different solar irradiance, load demand, and battery SoC conditions, the EMS stabilizes DC-link voltage and ensures a continuous charging process. PV, BESS, and grid sources will provide redundant power paths and fault tolerance for the system. Moreover, the proposed EMS was tested and validated in wired and wireless EV charging mode under dynamic and unbalanced power conditions. The simulation results show that the DC-link voltage overshoot is 4.7%, undershoot is 2.0%, settling time is 13ms, wireless charging efficiency is 96.4%, and overall energy management efficiency is about 90%.
