REVIEW ON EFFICIENT WIRELESS POWER TRANSFER TECHNOLOGIES FOR ELECTRIC VEHICLE CHARGING APPLICATIONS

Furthermore, this study proposes a smart grid-based wireless EV charging framework that integrates conventional utility power supply (MSEB) with renewable energy sources such as solar and wind energy. The proposed system utilizes an ESP32 microcontroller for intelligent monitoring and control, while DC voltage sensors continuously measure real-time voltage levels from multiple energy sources. Based on source availability and voltage conditions, relay-based switching enables optimal energy management and efficient power delivery to the wireless transmitter coil. The receiver coil acts as the charging load, demonstrating contactless energy transfer for EV charging applications. The integration of GSM communication and display modules enhances system reliability by providing real-time notifications, operational status updates, and fault alerts to users. The smart grid architecture improves energy utilization, reduces dependency on conventional power sources, and supports sustainable transportation infrastructure. The combination of renewable energy integration, IoT-enabled monitoring, wireless charging technology, and intelligent source management offers a practical solution for future smart EV charging stations. Future research can focus on improving wireless power transfer efficiency, implementing artificial intelligence-based energy management algorithms, vehicle-to-grid (V2G) integration, and developing adaptive charging strategies to further enhance the performance and scalability of smart wireless EV charging systems. Such advancements will play a crucial role in achieving energy-efficient, environmentally friendly, and intelligent transportation ecosystems.
