ORNL demos 20 kW bi-directional wireless charging on UPS PHEV truck; 11" air gap, >92% efficiency

Green Car Congress

Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) in late February demonstrated a 20-kilowatt bi-directional wireless charging system installed on a UPS medium-duty, plug-in hybrid electric delivery truck. The technology takes energy from the grid and converts it to direct current (DC) voltage.
