Introduction
The text presents a solar- and IoT-based Wireless Power Transmission (WPT) system designed to enable dynamic charging of electric vehicles (EVs). Rapid growth in EV adoption has exposed limitations of conventional plug-in charging, such as long charging times, range anxiety, grid dependence, and the need for fixed stations. To address these challenges, the proposed system integrates wireless charging embedded in road infrastructure, renewable solar energy, and IoT-based monitoring and control.
Wireless power is transferred using inductive coupling between transmitter coils embedded in the roadway and receiver coils mounted on the vehicle, allowing contactless and in-motion charging. Solar photovoltaic panels serve as the primary energy source, improving sustainability and reducing carbon emissions, while IoT technology enables real-time monitoring, automation, data acquisition, and optimization of power flow. Intelligent coil switching using IR sensors and relays minimizes energy loss and improves system efficiency.
The literature survey highlights prior work on resonant inductive coupling, compensation networks, solar-powered wireless charging, and IoT-based energy management, identifying benefits such as improved efficiency and challenges such as alignment sensitivity, maintenance cost, protocol integration, and limited solar availability.
The problem statement emphasizes the need for a reliable, efficient, and eco-friendly alternative to static, grid-dependent charging systems. The proposed solution aims to provide continuous, efficient, and sustainable charging for EVs while enhancing user convenience and system intelligence.
Experimental achievements include successful wireless power transfer, IoT-based real-time monitoring using ESP8266 and cloud platforms, efficient coil switching, and prototype validation with charging efficiency above 75% under laboratory conditions.
Future scope includes improving scalability and performance through solid-state switching, MPPT integration, advanced compensation networks, energy storage solutions, secure IoT protocols, and compliance with industry safety standards. Overall, the system represents a futuristic, sustainable, and efficient EV charging infrastructure capable of significantly enhancing EV range, efficiency, and environmental performance.
Conclusion
