There have been some laboratory experiments and theoretical work done to validate aspects of the plasma magnet propulsion concept. The Plasma Magnet is a wind drag device invented almost twenty years ...

Printed circuit board (PCB) coils have been proposed prior for implementation as inductive wireless charging coils to minimize size and cost. Utilization of PCBs can allow for a reduced cost, improved ...

ORNL first achieved 20 kW in wireless charging during a demonstration on a sports utility vehicle in 2016, the release says. It first achieved 120 kW using coil technology in 2018.

The ORNL-invented system that transferred power to the Porsche uses lightweight polyphase electromagnetic coupling coils with a diameter just over 19 inches that allow for higher power density in the ...

Using a novel polyphase wireless charging system that was seamlessly integrated into the EV’s underbody, researchers managed to transfer a peak power of 270 kW to the German sports sedan–the ...

By 2018, they reached 120 kW in lab tests with conventional coils. The recent 100- and 270-kW tests are the first applications of ORNL’s polyphase system on electric vehicles.

The team at Oak Ridge used lightweight polyphase electromagnetic coupling coils, featuring a relatively compact diameter of 19 inches.

The ORNL-invented system that transferred power to the Porsche uses lightweight polyphase electromagnetic coupling coils with a diameter just over 19 inches that allow for higher power density in the ...

The system uses a pair of polyphase electromagnetic coupling coils about 50 cm (19″) wide to transfer the power over a gap of approximately 13 cm (5″).
