Wireless Solar Electric Vehicle Charging System

Abstract

As the global demand for electric vehicles (EVs) continues to rise, the infrastructure supporting these vehicles must evolve to meet the growing need for efficient, user-friendly, and sustainable charging solutions. Traditional wired charging systems present several challenges, including cable wear and tear, manual connection inconvenience, and vulnerability to environmental hazards. To address these issues, a solar wireless EV charging system is proposed, integrating wireless charging technology with renewable energy sources to provide an innovative and eco-friendly charging solution. The system utilizes solar panels to capture and store energy, ensuring an environmentally friendly power supply independent of the grid. A key feature of this system is its use of inductive wireless charging, which eliminates physical connectors, thereby reducing maintenance costs and minimizing exposure risks. RFID technology is incorporated to provide secure user authentication and payment processing, enabling an automated and frictionless user experience. Ultrasonic sensors are employed to detect the presence of vehicles at the charging station, triggering system readiness without handling vehicle alignment. An automated gate control mechanism powered by servo motors ensures that only authorized vehicles gain access to the charging station. Real-time charging progress is displayed on an LCD interface, allowing users to monitor their charging status conveniently. A buzzer provides distinct auditory feedback a single beep upon authorized RFID scanning, three quick beeps for unauthorized access attempts, and a long beep to indicate charging commencement or completion. Additionally, a smart relay controls the power flow. By integrating these advanced features, the proposed system enhances the EV charging experience, making it more efficient, secure, and user-friendly. Furthermore, this solution contributes to global sustainability goals by utilizing clean, renewable solar energy and reducing dependence on conventional power grids.
