Abstract: Solar-Powered Smart Charging Station with Wireless power transfer (wpt) for EV and monitoring it by IoT presents a hassle-free EV charging solution by combining solar power with wireless charging technology. The system gets maximized by utilizing solar energy and the grid supply as a backup to provide continuous operation. Wireless charging does away with physical connectors by delivering energy through inductive coupling between coils. It includes RFID- enabled secure payment and access, enabling users to program charging by desired units. It has an LCD front panel that reports real-time data such as output voltage and payment status. Integrated sensors for fault detection and regulated DC-to-DC converters ensure safety through stable energy supply. Automatic switching of sources adds to the reliability. The system brings together energy efficiency, sustainability, and convenience of use, furthering the development of smart and green EV infrastructure.

Index Terms: Solar energy, wireless power transfer, electric vehicles, smart charging, RFID authentication, inductive coupling, IoT, DC-DC converters, fault detection, automated switching.
