The Smart Wireless EV Charging System Using Resonant Inductive Coupling for Rural Areas is designed to provide an efficient, contactless, and user-friendly charging solution for electric vehicles, especially in remote locations where conventional charging infrastructure is limited. The system utilizes resonant inductive coupling to transfer power wirelessly from a transmitting coil to a receiving coil without physical connectors. On the transmitter side, an IR sensor is employed for vehicle detection. When a vehicle is detected, the sensor sends a signal to the Arduino Nano, which activates a relay to turn ON the wireless power transmitting coil. This ensures that power is supplied only when a vehicle is present, improving energy efficiency and safety. Additionally, the system integrates an ESP8266 Wi-Fi module to upload charging parameters such as charging time and billing details to the ThingSpeak cloud platform for real-time monitoring and data analysis. On the vehicle (receiver) side, the wireless power receiving coil captures the transmitted energy, which is then regulated using a TP4056 charging module to safely charge a 3.7V Li-ion battery. Switches are provided to control the vehicle’s DC motors, enabling basic operational control. A boost converter is used to step up the voltage, and the output is displayed on a seven-segment display to indicate the received voltage level, ensuring proper monitoring of the charging process. Overall, the proposed system offers a smart, automated, and cost-effective wireless EV charging solution with IoT-based monitoring, making it highly suitable for rural and semi-urban environments.
