The transmitter is compact, at just over 14 inches in diameter, and utilizes an innovation ORNL created in 2022 called the “polyphase electromagnetic coupling coil” with rotating magnetic fields.

Wireless charging is conceptually simple. Two coils form an ad hoc transformer with the primary in the charger and the secondary in the charging device. However, if you’ve ever had a wireless ...

Indiana researchers are testing out a highway that can wirelessly charge electric vehicles. They say their technology is so powerful that it can even charge an electric semitruck. Transmitter ...

These charging panels include the primary coils that can send up to 200 kilowatts of power − roughly the electricity it takes to power 100 homes − to the vehicle's motor.

The study on wireless power transfer highlights ferrite integration in coil designs, which improves EV charging efficiency and supports sustainable transportation.
