Utah State University Unveils Wirelessly Charged Electric Bus
Utah State University presented a first-of-its-kind electric bus that is charged through wireless charging technology in a demonstration Nov. 15. The Aggie Bus rolled onto the streets carrying passengers just 16 months after USU demonstrated the first high-power, high-efficiency wireless power transfer system capable of transferring enough energy to quickly charge an electric vehicle. In July 2011, the USU Research Foundation demonstrated 90 percent electrical transfer efficiency of five kilowatts over an air gap of 10 inches. The demonstration validated that electric vehicles can efficiently be charged with wireless technology.
