Abstract : Electric Vehicle Charging Stations (EVCS) with Solar Photovoltaic (PV) integration require efficient power management to ensure grid stability and battery longevity. This study proposes a hybrid energy storage system (HESS) utilizing Superconducting Magnetic Energy Storage (SMES) and Battery Energy Storage System (BESS) to mitigate transient power fluctuations and optimize energy distribution. The proposed current control strategy is validated through MATLAB/Simulink simulations under Variable Load Constant Generation (VLCG) and Constant Load Variable Generation (CLVG) scenarios. The results indicate that SMES integration reduces the peak battery current by 52.63 % and 32.72 % following the connections of EV-1 and EV-2, respectively, thereby enhancing battery lifespan. Additionally, real-time validation using the dSPACE DS1202 platform confirms that the proposed system effectively stabilizes grid voltage and optimizes power flow under varying load and power generation conditions. The findings demonstrate the efficacy of the HESS in reducing peak transient currents and improving the overall reliability of solar PV-supported EVCS.
