The US Department of Energy’s Oak Ridge National Laboratory (ORNL) has licensed its high-power wireless charging technology for electric vehicles to HEVO. The system provides the world’s highest power levels in the smallest package and could one day enable electric vehicles to be charged as they are driven at highway speeds. ORNL has licensed its high-powered wireless vehicle charging technology to HEVO, including the lab’s unique, compact polyphase electromagnetic coils that provide the highest surface power density available. Credit: Carlos Jones/ORNL, US Dept. of Energy. The license covers ORNL’s unique polyphase electromagnetic coil that delivers the highest surface power density available, 1.5 megawatts (1,500 kilowatts) per square meter—eight to 10 times higher than currently available technology. This surface power density supports higher power levels in a thinner, lighter coil, resolving the issue of adding range-sapping weight to electric vehicles. The license also includes ORNL’s Oak Ridge Converter, which eliminates […]
