The increasing adoption of electric vehicles (EVs) demands efficient, flexible, and sustainable charging solutions to overcome limitations such as long charging times and range anxiety. This project presents the design and implementation of a Solar Wireless Dynamic Electric Vehicle Charging System, which enables contactless power transfer to an electric vehicle using renewable energy sources. The system integrates solar power and conventional grid supply to charge a battery through appropriate charging circuits, ensuring uninterrupted operation under varying environmental conditions. An Arduino-based control unit regulates the charging process and controls a MOSFET switching board that drives multiple wireless power transmitting coils. These coils are arranged to support dynamic charging, allowing power transfer while the vehicle is in motion. On the receiver side, a wireless receiving coil captures the transmitted energy, which is then converted into usable DC power using a rectifier circuit. A voltmeter is incorporated to monitor the received battery voltage in real time. The proposed system demonstrates a cost-effective, efficient, and environmentally friendly approach to EV charging. By eliminating physical connectors and enabling dynamic charging, the system reduces charging downtime, enhances user convenience, and promotes the use of renewable energy for sustainable transportation. This project highlights the potential of wireless power transfer technology as a promising solution for future smart transportation infrastructure.
