Wireless Power Transmission by Resonant Power Converters for Charging of EVs

Abstract

Wireless Power Transmission is gaining traction as a versatile, safe, convenient and self-contained charging option for electric vehicles and plug-in hybrids. The separation between the transmitter coil and the vehicle mounted receiver coil contributes to WPT's safety. Wireless charging may also be used in extreme weather without being impacted by snow or rain, and without the use of bulky cables or heavy-duty plugs. Wireless power transmission is flexible and convenient not just because wires or connectors are not required, but also because charging becomes completely self-contained. As advances in this domain continues, it's not impossible to imagine a vehicle capable of sensing magnetic field or a parking assist capable of positioning itself over a primary pad for optimal alignment and autonomous charging. By incorporating WPT into EVs, the challenges of charging time, range, and cost may be easily overcome. In the broad market adoption of electric vehicles, battery technology is no longer significant. It is believed that the cutting-edge results would inspire academics to continue developing WPT and expanding EV.
