Oak Ridge National Laboratory (ORNL) researchers wirelessly charged a light-duty passenger EV at 100 kW with 96% efficiency – a new milestone.
Scientists at the US Department of Energy-funded ORNL wirelessly charged the EV using polyphase electromagnetic coupling coils with rotating magnetic fields.
ORNL’s patented system transferred power to a Hyundai Kona EV across a five-inch air gap using electromagnetic fields, a process similar to the wireless charging of small consumer devices.
