Abstract: An IoT- based solar wireless power transfer (WPT) system designed to enable efficient, cable-free charging for electric vehicles (EVs). It is an innovative solution that combines renewable energy with wireless charging technology. In this system, a solar panel captures sunlight and converts it into electrical energy, which is regulated using a charge controller and stored in a battery. The stored energy is then supplied to an Arduino Uno, which manages system operations and controls the wireless transmitter coil through a relay module. Power is transferred wirelessly via electromagnetic induction from the transmitter coil to the receiver coil mounted on the vehicle side. The received energy is stored in a battery and monitored using sensors, while an ESP32 module enables IoT-based data monitoring and control. The system also integrates street light automation using IR and LDR sensors for energy efficiency. Overall, this paper provides an eco-friendly, efficient, and smart charging solution for electric vehicles with reduced wiring and enhanced automation.
