Development Of A Sustainable EV Fast Charging Infrastructure Using A Hybrid Solar-Battery System

Abstract—The growing adoption of electric vehicles (EVs) has significantly increased the demand for electricity, leading to greater reliance on the conventional power grid. This increased dependency poses challenges for sustainable EV charging, especially when the grid is powered by non-renewable energy sources. To address this, a grid-integrated solar-based EV charging system is proposed in this work. The system utilizes photovoltaic (PV) panels as the primary energy source, supported by backup battery unit to ensure continuous charging availability during periods of solar irradiance. Moreover, the system is interfaced with the utility grid to enable bidirectional power exchange, thereby improving system reliability and operational adaptability. An advanced Maximum.Power.Point Tracking.(MPPT) technique.is.utilized to ensure optimal energy harvesting from the photovoltaic (PV) array under dynamically changing irradiance and temperature conditions. The integration of renewable energy, backup battery, and grid connectively ensure efficient, reliable, and environmentally friendly charging, while reducing the overall dependency on the grid.
