Wireless power transfer system achieves 270-kilowatt charge
Researchers at the Department of Energy’s Oak Ridge National Laboratory have successfully demonstrated the first 270-kW wireless power transfer to a light-duty electric vehicle. The demonstration used a Porsche Taycan and was conducted in collaboration with Volkswagen Group of America using the ORNL-developed polyphase wireless charging system.

Volkswagen Group officials visited ORNL to view the lab’s novel lightweight polyphase electromagnetic charging system, capable of transferring unprecedented power to electric vehicles. These demonstrations advance DOE’s extreme fast-charging goal to develop a system that delivers 250 to 300 kilowatts to electric vehicles and reduces charging time to 15 minutes or less.
