Wireless system can charge cars with up to 85 percent efficiency.
The Hyundai-Kia America Technical Center (HATCI) and Mojo Mobility have completed a three-year project to develop a fast-charging wireless power transfer system on a test fleet of Kia Soul EVs.
The system can transfer more than 10 kW to the vehicle, and was tested on five Soul EVs in real-world applications for durability, safety and performance.
An electromagnetic field is employed to transfer energy between two coils—a transmitter on the ground and a receiver on the bottom of the vehicle. The driver simply parks the car above the transmitter to begin charging and then energy is sent through an inductive coupling to an electrical device, which uses that energy to charge the electric vehicle’s battery.
“We’re thrilled with the success of the system and its efficiency,” said William Freels, HATCI President. “We set out to develop wireless charging that has real world applications and is easy to use for the consumer. Now, with this fleet of wireless Soul EVs, we can clearly see a future of unplugged electric vehicles.”
The company says they’re not planning to offer wireless charging system on production vehicles anytime soon, but it could be a possibility on some of their future electric vehicles.
