Abstract : As the new era of automobile industry is rapidly transforming from an IC engine vehicle to an electric vehicle, the demand for an electric vehicle is increasing. This leads to an increase in charging stations as well. In this project, a wireless charging system is used to charge the vehicle wirelessly via inductive coupling. We just need to park the car on the charging spot. The transmission of electrical energy from source to load from a distance without any 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 is one step forward towards the future. This project can open up new possibilities of wireless charging that can be used in our daily lives.
Wireless power transfer (WPT) using magnetic resonance is the technology that could set human free from the annoying wires. In fact, the WPT adopts the same basic theory which has already been developed for at least 30 years with the term inductive power transfer. WPT technology has been developing rapidly in recent years. At milli watts to kilowatts power level, the power transfer distance increases from several millimeters to several hundred millimeters with a load efficiency above 90%. The advances make the WPT very attractive to electric vehicle (EV) charging applications in both static and dynamic charging scenarios.
The integration of IoT further elevates the capabilities of wireless charging systems. With IoT, the charging process becomes smarter and more connected. Real-time data can be collected and analysed, allowing for more efficient management of charging stations. IoT enables features such as remote monitoring, predictive maintenance, and dynamic load balancing. The seamless incorporation of WPT and IoT in EV charging addresses challenges related to charging time, range, and cost. This convergence renders traditional battery technology less critical in the mass market adoption of EVs. The project envisions researchers leveraging these state-of-the-art achievements to drive further advancements in WPT and foster the broader expansion of electric vehicles.
