This paper describes the development of a hybrid charging station that integrates solar photovoltaic (PV) energy with the utility grid to ensure dependable power delivery for electric vehicle (EV) charging. This system’s central component is a Buck-Boost DC-DC converter, which controls the output voltage by switching between buck and boost modes according to the load demand and solar energy availability. The performance of each subsystem, such as the PV source, converter topology, switching control, and charging interface, is tested using a MATLAB/Simulink model. The buck-boost converter successfully maintains a steady DC output in spite of variations in solar irradiance and changing load conditions, according to simulation results. This system automatically draws additional energy from the grid to ensure continuous operation when the solar power is insufficient to meet the demand. In addition to increasing the use of renewable energy sources and improving energy reliability, the hybrid configuration offers a flexible and effective solution appropriate for contemporary EV charging infrastructure.
