Delphi Showcases Innovative Wireless EV Charging

Delphi Automotive has equipped an electric vehicle with its Delphi Wireless Charging System, a highly efficient wireless energy transfer system featuring technology developed by WiTricity Corporation. Delphi will display the test vehicle at this year's SAE World Congress this week.

A wireless charging system eliminates the need for a charging cord. Drivers can simply park their electric vehicle over a wireless energy source situated on the garage floor or embedded in a paved parking spot. Other wireless charging systems under development make use of traditional inductive charging, the same technology used in electric toothbrushes, which is based on principles first proposed in the mid-nineteenth century. These systems only work over a limited distance range, require precise accurate parking alignment and can be very large and heavy, making them impractical for widespread use on electric vehicles.
