Circular Coil Design Selected for EV Charging Test Station by Leading International Automotive Standards Body

Watertown, Mass. – January 26, 2017 WiTricity, the industry pioneer in wireless power transfer over distance, today announced that the SAE International’s J2954™ Taskforce has selected a circular coil topology for its official test station against which EV wireless charging systems will be tested for interoperability and standards compliance.  Products developed by carmakers, Tier 1 suppliers and charging infrastructure suppliers will be measured against 3.7 kW and 7.7 kW test stations.

The agreement on key technical and procedural elements of the standard was reached at a meeting of the SAE J2954™ Task Force members held in Ingolstadt, Germany in mid-January. The goal of the task force is to develop a standard that ensures interoperability between the wide range of electrified vehicles being developed by carmakers worldwide and the wireless charging stations that will be widely deployed to streamline the charging of the next generation of EVs and PHEVs.

Vehicle electrification is a priority for automakers, and providing drivers with the most convenient charging experience is critical to reaching mass adoption. Wireless charging has emerged as a preferred solution for electric vehicles and for the autonomous electric vehicles that are expected to be in the market in the coming years. The SAE J2954™ Task Force is developing the standards for wireless charging that enables automakers and their suppliers, as well those companies planning to build and operate wireless charging stations for public usage, to offer seamless interoperability on a global basis.

WiTricity’s DRIVE series of EV reference designs include 3.7 kW, 7.7 kW and 11 kW, scaling to 22 kW and higher, and is based on the company’s patented magnetic resonance technology. These designs deliver superior end-to-end efficiency of 91%-94% and combine WiTricity’s innovative TMN™ technology with its circular coil design.

“Our team has pioneered the technology for wireless charging systems that not only deliver the power levels and high efficiency needed for today’s vehicles, but also are very interoperable. Our automaker customers want to know that their cars will work with charging stations around the world, and a global standard makes that possible,” said Alex Gruzen, CEO, WiTricity. “With this progress toward standardization, carmakers and charging system providers can now accelerate their vehicle production programs with confidence.”

WiTricity is working with major automakers and Tier 1 suppliers including Toyota, Delphi, TDK, IHI and BRUSA to bring the next-generation of wireless EV charging to a commercial reality. The company has also announced it is working with General Motors (GM) and Nissan in testing the DRIVE system. For more information on the SAE J2954™ standard visit: [].
