Contrary to general belief, wireless power transfer (WPT) has been in use for a long time. The microwave oven uses the concept of wireless power transfer to heat food. Laser is another method which uses similar concept as wireless power transfer…

However, most of these methods are not designed for the transfer of electricity, especially for an Electric Vehicle (EV). So, there is a requirement to understand the methods to study the Wireless Power Transfer technology related to Electric Vehicle (EV) charging. In this context, wireless power transfer using Electromagnetic Resonance (or otherwise, inductive charging) which can transfer power over medium distance (range of millimeters to tens of centimeters) is the topic of discussion.
