Shindengen Licenses WiTricity Technology for EV Wireless Charging

September 27, 2017 by Paul Shepard

WiTricity today announced an intellectual property licensing agreement with Shindengen, a Tier 1 supplier to global carmakers and motorcycle manufacturers. Under the terms of the agreement, Shindengen will license WiTricity's patented technology to develop and commercialize high-performance wireless charging systems.

These systems will enable next generation electric vehicles (EVs) and hybrid electric vehicles (HEVs) to charge effortlessly by simply parking over a wireless charging pad. Shindengen will utilize WiTricity's DRIVE 11 reference design to accelerate its development of Shindengen products for both the vehicle and for the charging pad.

The DRIVE 11 system can fully charge a long-range EV overnight (identical charge time as conventional wired chargers) and can re-charge a hybrid vehicle in an hour or less.

Carmakers around the world have identified wireless charging as a key differentiator in the marketplace because of the convenience it offers to vehicle owners. Shindengen's wireless charging system, utilizing WiTricity's patented technology, will transfer power to a vehicle safely and at high efficiency, eliminating the need for plug-in charging cables required by first generation electrified vehicles.

WiTricity is working with a number of international standards organizations, such as SAE J2954, to develop standards for wireless charging systems with the goal of ensuring interoperability of wireless charging systems for EVs and HEVs on a global basis.
