Abstract

The global automotive industry is witnessing a significant paradigm shift from Internal Combustion Engine (ICE) vehicles to Electric Vehicles (EVs) as a primary strategy to mitigate climate change and reduce dependency on fossil fuels. However, the mass adoption of EVs is currently impeded by the lack of convenient, efficient, and sustainable charging infrastructure. Traditional plug-in charging stations suffer from mechanical wear and tear, safety hazards related to exposed connectors, and a reliance on the non-renewable power grid. This research paper proposes the design and development of a Solar-Powered Wireless EV Charging Station integrated with a smart IoT-based Automated Booking System. The proposed system leverages the principle of Inductive Power Transfer (IPT) to charge vehicles wirelessly, thereby eliminating the need for physical cables and connectors. The system is completely off-grid, powered by a high-efficiency Solar Photovoltaic (PV) array coupled with a battery backup and a Buck converter for voltage regulation. The core control logic is executed by an ESP32 microcontroller, which facilitates real-time communication between the charging station and the user via the MQTT protocol. A custom-built web interface allows users to check availability, book charging slots, and monitor the charging status remotely. The station also incorporates IR sensors for precise vehicle detection, ensuring that power transfer is activated only when a valid vehicle is aligned with the transmitter coil. This project demonstrates a scalable, eco-friendly, and user-centric solution for future smart city transportation networks.

Conclusion

This paper successfully demonstrates the design and implementation of a Solar-Powered Wireless EV Charging Station integrated with a smart IoT ecosystem. The project addresses key challenges in the current EV infrastructure by eliminating physical connectors and integrating renewable energy. ●The Wireless Power Transfer mechanism achieved a stable voltage transmission over an air gap of up to 20mm, proving the viability of inductive coupling for consumer convenience. ●The IoT Booking System effectively managed user slots, reducing the uncertainty of station availability and demonstrating a scalable model for smart city applications. ●The integration of Solar Energy makes the station self-reliant and eco-friendly, aligning with global sustainability goals. In conclusion, this prototype serves as a foundational model for future “Green Corridors” where electric vehicles can charge seamlessly and sustainably.
