A 20-kilowatt wireless charging system demonstrated at the U.S. Department of Energy’s Oak Ridge National Laboratory has achieved 90 percent efficiency and at three times the rate of the plug-in systems commonly used for electric vehicles today.
This ability can help accelerate the adoption and convenience of electric vehicles. Industry partners from Toyota, Cisco Systems, Evatran, and Clemson University International Center for Automotive Research contributed to the technology development demonstrated today at ORNL.
“We have made tremendous progress from the lab proof-of-concept experiments a few years ago,” said Madhu Chinthavali, ORNL Power Electronics Team lead. “We have set a path forward that started with solid engineering, design, scale-up, and integration into several Toyota vehicles. We now have a technology that is moving closer to being ready for the market.” [Read more…]
