According to the abstract released by the Intellectual Property India: "A solar-assisted electric vehicle (EV) charging framework incorporating a Maximum Power Point Tracking (MPPT) enabled DC-DC boost converter using the Perturb and Observe (P&O) control algorithm is disclosed. The invention relates to renewable-energy-based EV charging systems designed to ensure efficient power extraction from pbotovoltaic (PV) arrays and stable battery charging under varying environmental conditions. Conventional EV charging stations primarily rely on grid-supplied electricity or employ fixed-duty or constant-voltage control strategies that fail to adapt to fluctuations in solar irradiance and temperature, resulting in reduced energy utilization and unstable charging performance. The proposed system integrates PV modules, a DC-DC boost converter, an embedded MPPT controller implementing the P&O algorithm, and an EV battery management interface. The controller continuously senses PV voltage and current, calculates instantaneous power, and compares present and previous operating points to determine optimal duty-cycle adjustments of the boost converter. This adaptive control mechanism drives the PV array to operate near its maximum power point in real time, thereby maximizing solar energy harvesting and ensuring smooth and efficient energy transfer to the EV battery. Simulation and functional evaluation demonstrate tracking accuracy of approximately 99%, charging efficiency exceeding 90%, improved state of charge, and stable output voltage within the required charging range. Compared with conventional fixed-duty PWM charging systems, the invention offers faster convergence to optimal operating conditions, higher renewable energy utilization, and enhanced battery life through regulated charging. The framework is suitable for standalone, hybrid, and off-grid EV charging stations, particularly in rural or distributed energy environments."
