Solar powered wireless car charging station

As the new era of the automobile, the industry is rapidly transforming from an IC engine vehicle to an electric vehicle. The demand for an electric vehicle is increasing, these lead to an increase in charging station as well. In this work, a wireless charging system is used to charge the vehicle wirelessly via inductive coupling. It is just simply need to park the car on the charging spot. The transmission of electrical energy from source to load from a distance without any conducting wire or cables is called Wireless Power Transmission. The concept of wireless power transfer was the greatest invention by Nikola Tesla. This system doesn’t require any human interaction. Wireless power transmission might be one of the technologies that are one step towards the future. This work can open up new possibilities of wireless charging that can use in our daily lives. It explores the potential of wireless vehicle charging, a key technology for the evolving electric vehicle industry. By eliminating the need for cables, the system offers a convenient and efficient charging solution. Inductive coupling transfers electrical energy from a ground pad to a receiver coil in the vehicle, requiring only parking the vehicle on the designated spot. The design comprises primary and secondary circuits and a control unit. The primary circuit generates a high-frequency magnetic field, while the secondary circuit converts it back to usable DC voltage. An Arduino microcontroller monitors and displays the charging status. Performance analysis ensures the system's functionality and paves the way for further development in practical applications.
