WORKING PRINCIPLE

The IoT Based Solar Wireless Charging System for Electric Vehicles operates using a transmitter side and a receiver (vehicle) side. On the transmitter side, the solar panel converts sunlight into electrical energy, which is stored in a battery. A buck converter regulates the voltage to the required level for stable operation. An IR sensor detects the presence of the vehicle on the charging pad and activates a relay, which switches ON the transmitter circuit. The transmitter generates high-frequency power and energizes the transmitter coil, creating an alternating magnetic field.

On the receiver side, the receiver coil mounted on the vehicle captures this magnetic field through inductive coupling and converts it into electrical energy. A buck converter regulates the voltage to the required level for stable operation. A temperature sensor monitors battery temperature, while the NodeMCU processes system data and enables IoT monitoring. Charging status and parameters are displayed on an LCD. The motor driver controls the gear motors, enabling wheel movement during vehicle operation.
