Abstract: This project introduces a solar-based wireless charging system for electric vehicles (EVs), designed to provide a contactless, automated, and sustainable energy transfer method using inductive coupling technology.The primary objective is to eliminate the need for physical connectors, reduce human intervention, and enable environmentally friendly EV charging using renewable energy sources.The system harnesses solar energy via a 12V, 10W polycrystalline solar panel, which charges a Li-Ion battery through a solar charge controller.The stored energy is then used to power a high-frequency wireless transmitter coil.When an EV is detected at the station using an IR sensor, the system automatically activates a servo motor that aligns the transmitter coil to maintain an optimal 10mm distance from the vehicle's receiver coil, ensuring maximum energy transfer efficiency.The receiver side of the EV includes a coil that captures the magnetic field, a rectifier to convert the received AC into DC, a 7805 voltage regulator, and a charging module for safe battery management.The energy is then stored in the EV's onboard battery and used to drive a DC motor, simulating EV movement.A voltage sensor continuously monitors the battery, and the status is displayed on a 16x2 I2C LCD screen, indicating states such as "Full", "Half", or "Not Charging".This system not only demonstrates wireless power transmission but also integrates automation, IoT-based monitoring potential, and renewable energy for a fully self-sustaining setup.Its compact and modular design makes it ideal for small-scale applications like autonomous delivery robots or prototype electric cars and opens the door to future scalability for full-size EVs.By eliminating wear-prone connectors and supporting real-time battery monitoring, the project addresses key challenges in modern EV charging.Furthermore, the implementation of smart alignment using servo motors, and the potential to extend the system with IoT platforms like Firebase/Blynk, makes it a next-generation charging model.
