Abstract- This paper aims to develop wireless charging technologies and it is also intended to give a message that how useful the plug-less battery car charging is by creating a proof of concept for inductive charging. Also this paper is designed to charge a rechargeable battery wirelessly. Since charging of the battery is possible to be demonstrated. This paper is built upon using an electronic circuit which converts AC 230V 50Hz to AC 12V. The output is fed to a tuned coil forming as primary of an air core transformer. The secondary coil develops a voltage of HF 12volt. Thus the transfer of power is done by the primary (transmitter) to the secondary (receiver) that is separated with a considerable distance. Therefore the transfer could be seen as the primary transmits and the secondary receives the power to run load. Moreover this technique can be used in number of applications, like to charge a mobile phone, iPod, laptop battery. And also this kind of charging provides a far lower risk of electrical shock as it would be galvonically isolated. This concept is an Emerging Technology, and in future the distance of power transfer can be enhanced as the research across the world is still going on.
All aspects of this vehicle are governed by the law of conservation of energy. The system here proposed can be useful for electric vehicle (EV) battery charging systems. It consists mainly of two copper coils, placed one in front of the other on the same axis. The inductor coil can easily be placed under the road surface (in a parking), while the other (the receiver coil) in the lower side of the vehicle. By exploiting the coils resonance coupling effect, electric energy can be transferred from the inductor coil to the receiver in order to charge the batteries. Wireless power transfer (WPT) using magnetic resonance is the technology which could set human free from the annoying wires. The advances make the WPT very attractive to the electric vehicle (EV) charging applications in both stationary and dynamic charging scenarios.
