Renewable energy-based electric vehicle (EV), in order to guarantee a consistent and dependable power source, this study presents, a method for charge batteries which incorporates a solar energy system with a backup energy storage system (ESS). The PV system serves as the primary energy source, while excess energy generated during peak sunlight hours is stored in the ESS. During insufficient solar power conditions, such as bad weather or night time, the stored energy is utilized to maintain uninterrupted EV charging. The Proportional-Integral (PI) controller has been employed for regulating both the charging & discharging processes, ensuring stable voltage and current levels while preventing overcharging or deep Discharge from the storage system setup. The method enhances the use of energy, reduces dependence on the grid, and helps establish an environmentally friendly charging network for electric vehicles. Simulation and experimental results validate its effectiveness in maintaining a stable power supply under varying environmental conditions. MATLAB/Simulink software will be used to model a stand-alone, photovoltaic-powered electric vehicle battery charging system.
