Design and Development of Wireless Electric Vehicle Charging System with Foreign Object...

Objective: To engineer and demonstrate a safe, efficient wireless EV charging prototype incorporating real-time foreign object detection for urban public and residential settings.

India faces rapid EV adoption challenges in urban areas, where convenient charging access and user safety are critical. Conventional plug-in chargers present risks of cable wear, vandalism, and accidental contact, and wireless charging is emerging as a modern solution for public and residential spaces.

This project proposes an engineering solution by designing and fabricating a wireless EV charging system based on resonant inductive coupling, integrated with foreign object detection using sensor arrays and embedded control. The system prevents energy transfer in the presence of metallic or living objects, addressing safety concerns and efficiency losses.

Key deliverables include a working prototype featuring a transmitter pad, receiver coil (EV-side), object detection sensors (capacitive/IR/metal), a microcontroller-based safety logic, and a monitoring interface. Students will demonstrate live charging, detection response, performance metrics (power transfer efficiency, detection accuracy), and compliance with IEC 61980 and IS 17017 standards.

The project impacts urban infrastructure scalability for EVs, reducing hazards, and aligning with Smart City initiatives. The modular solution can be adapted for public parking, residential complexes, and commercial fleets, facilitating safer, user-friendly EV charging across India.
