In response to the global demand for clean and efficient transportation infrastructure, our project introduces an innovative solar-powered wireless charging station for electric vehicles (EVs). This smart system integrates inductive charging, renewable energy utilization, and secure access control through RFID and keypad authentication, eliminating the need for physical connectors and reducing dependence on the electrical grid.

Designed for both Vehicle-to-Grid (V2G) and Vehicle-to-Load (V2L) applications, the system not only charges EVs wirelessly but also enables them to supply power back to the grid or to external devices. It ensures optimized energy management through an Arduino-based control unit and offers real-time status updates via an IoT interface.

This multi-port charging solution enhances accessibility, supports simultaneous charging, and promotes eco-friendly energy distribution, making it ideal for smart cities, residential areas, and off-grid rural applications. Our prototype demonstrates 90% power transfer efficiency and 98% authentication accuracy, ensuring reliability, scalability, and security.

We believe our project stands out for its sustainable impact, technical innovation, and potential to accelerate the green energy transition in electric mobility.
