This paper introduces a prototype for charging an EV wirelessly through renewable energy sources while also monitoring the battery status and show this information on the Internet through an online website and mobile application. In this way, this prototype focuses on improvising the EV charging experience for the user, while also enhancing safety and efficiency. The system utilizes energy generated by the Solar PV module while also being able to use energy from the battery and main grid if needed. This prototype uses DC power for demonstration purposes. The Output power of the sources is reduced from a 12V DC supply to a stable 5V DC with the help of a Buck converter. This energy is sent to the transmitter coils for wireless power transfer (WPT). After the receiver coil receives this power, it is sent to the battery for charging while the IoT circuit, consisting of microcontroller, sensors and transmitter, monitors the battery parameters while also uploading this data to the internet for the user to monitor.
