The demand for efficient and environmentally friendly battery charging solutions has been heightened by the quick advancements in the automotive sector, which have sped up the acceptance of electric vehicles (EVs). Electric vehicle charging on the conventional grid results in non-renewable energy use and peak load stress. This study presents a grid-independent method of charging electric vehicle (EV) batteries that is based on photovoltaic (PV) arrays and may be used off-board. To ensure that electric vehicle batteries can be charged regardless of fluctuations in solar irradiation, it is advised to have a backup battery bank and PV array. To prevent the PV output voltage from fluctuating, a Single-Ended Primary Inductor Converter is used. The Perturb and Observe (P&O) algorithm used in the ATmega328 microcontroller guarantees the most efficient energy extraction from PV arrays in a wide range of environmental circumstances using Maximum Power Point Tracking (MPPT). You may regulate the charging and draining of the EV battery and backup battery using a bidirectional DC-DC converter. During times of maximum sunlight, the PV array charges the primary and secondary batteries of the electric car. In cloudy or low-light conditions, the electric vehicle may still be powered by the backup battery. The complete system, including power electronic converters, sensors, gate drivers, and the ATmega328 controller, is modeled and simulated using Proteus Design Suite. Unlike conventional MATLAB/Simulink-based system-level simulations, Proteus enables real-time hardware-oriented validation with embedded C code execution, PWM signal generation, ADC-based sensing, and LCD interfacing. Experimental validation through laboratory prototype testing confirms stable voltage regulation, efficient MPPT performance, smooth bidirectional power flow control, and reliable EV battery charging. With better energy management and increased dependability, the suggested system proves to be an efficient, affordable, and scalable answer for autonomous solar-powered electric vehicle charging applications.
