Abstract

This project presents a Solar Wireless Electric Vehicle (EV) Charging System that integrates solar energy with inductive wireless power transfer (WPT) to achieve a sustainable and eco-friendly charging approach. The proposed system utilizes a 12V solar panel as the primary renewable energy source, which charges a 3.7V lithium-ion battery through a transistor-based control circuit. This stored solar energy then powers the primary coil, generating an alternating magnetic field that enables contactless energy transfer to the secondary coil mounted in the EV. The received power is rectified and utilized to charge the onboard battery, with an LED indicator providing visual confirmation of active charging. The system eliminates the need for physical connectors, reducing mechanical wear and improving user convenience, especially in outdoor or adverse weather conditions. Through experimental testing, the setup demonstrated efficient short-range energy transfer, though challenges such as coil misalignment, distance sensitivity, and conversion losses were observed. These factors slightly affected overall system efficiency but can be mitigated through improved coil design and alignment mechanisms. Overall, the proposed design illustrates the feasibility of off-grid, solar-assisted wireless EV charging as a step toward green mobility and sustainable transportation infrastructure. It emphasizes the potential for expanding renewable-powered wireless systems in future smart cities and electric mobility ecosystems, promoting a cleaner and more energy-independent future.
