Sustainable charging framework: Solar wireless EV charging enhanced with MPPT control

The rapid growth of electric vehicle (EV) adoption demands efficient, reliable, and sustainable charging solutions. Traditional plug-in charging methods pose limitations such as cable wear, electrical hazards, and user inconveniences. This study introduces an innovative solar-powered wireless charging system designed to deliver consistent power while reducing dependence on non-renewable energy sources. The system integrates Maximum Power Point Tracking (MPPT) using the Perturb and Observe (P&O) method to maximize energy extraction from solar photovoltaic (PV) arrays. It employs a Series-Series (SS) compensated topology to enhance power transfer efficiency and minimize energy losses. The proposed model operates in three modes: solar-only, grid-only, and hybrid solar-grid, ensuring uninterrupted charging under varying environmental conditions. Simulation results in MATLAB Simulink demonstrate the system’s capability to deliver a stable 240 V and 32 A output, matching the charging specifications of a Tesla Model 3 battery pack rated at 54 kWh. Under ideal sunlight conditions (irradiance = 1000 W/m², temperature = 25°C), the PV array generates 88.97 kW, fully meeting the system’s power demand. When solar irradiance drops to 250 W/m², power generation decreases to 21.61 kW, triggering seamless switching to grid power without interrupting charging operations. The results confirm that the designed system achieves high efficiency, process flexibility, and continuous functionality. This makes it a viable solution for green, wireless EV charging infrastructure, supporting sustainable transportation and reducing dependency on fossil fuels. A hybrid EV wireless charging system combining solar PV and grid power with seamless switching. Utilizes MPPT control and SS topology for optimal efficiency and minimal loss and delivers a constant 240 V/32 A output, supporting sustainable transportation.
