ORNL researchers demonstrate a groundbreaking 270-kW wireless EV charging system, in collaboration with Volkswagen on a Porsche Taycan.
Researchers at Oak Ridge National Laboratory have successfully demonstrated the first 270-kW wireless electric vehicle charging technology.for wireless EV charging with its demonstration of a 100 kW charger in March.
According to the team, current research is focused on developing wireless charging systems for light-duty cars that can achieve up to 11 kW of power and 92 percent efficiency. Industry standards currently cover power levels up to 20 kW. Researchers say this is achieved through rotating magnetic fields created by the coil phase windings, which enhance power delivery. The charging system was efficiently incorporated into the vehicle’s undercarriage.
“We’re also working with Volkswagen on developing a polyphase system for residential charging applications and collaborating on the development of a lightweight enclosure design that will improve mechanical, electrical, thermal, and magnetic performance,” said Omer Onar, ORNL’s leader of the Vehicle Power Electronics group and lead researcher on the Porsche demonstration.For the past decade, ORNL researchers have advanced wireless charging technology.
