Massachusetts based wireless power transfer specialist Witricity is working with General Motors to test an advanced wireless charging system prototype for electric vehicles. If successful, the technology could transform the utility and commercial acceptance of electric vehicles, and accelerate their uptake, particularly in cities.

Witricity and GM are working together to test WiTricity's Drive 11 park and charge system. The prototype testing focuses on wireless charging systems at 7.7 and 11 kW charge rates, capable of charging both battery electric vehicles (BEVs) and extended range electric vehicles (EREVs), and is intended to comply with standards proposed by SAE International’s J2954 Committee.

To improve understanding of real world performance and the challenges integrating this technology into vehicles, GM is testing WiTricity’s prototype wireless charging system, which allows a driver to simply pull into his or her garage and automatically receive power from a source below the vehicle. The system design works across all plug-in electric vehicle platforms and can be deployed as a “floor pad” in a consumer’s garage, as well as installed under pavement to provide wireless charging in public and commercial parking lots.

"Wireless charging is a technology that our customers have told us they are interested in,” said Pamela Fletcher, GM Executive Chief Engineer – Electrified Vehicles. "By testing the WiTricity prototype system, we can ensure that wireless charging systems will comply with proposed industry standards, which benefits the entire industry and consumers.”

"The electric vehicle has been recognised as central to the future of mobility, and GM has been a leader, making EVs accessible to the broader market. The convenience of wireless charging will help accelerate adoption even further," said Alex Gruzen, CEO, WiTricity. "Our team is proud to work with GM on this project. Wireless charging for EVs, based on industry standards, is inevitable as we move toward a future of self-driving and autonomous vehicles, and this project brings us one step closer to realising our vision of a world powered wirelessly."

WiTricity says it is working with major automakers and Tier 1 suppliers to bring the next generation of wireless EV charging to a commercial reality. 

Licensing agreements have been announced with Toyota, Delphi, TDK, IHI and BRUSA. WiTricity is also collaborating directly with leading car makers to drive global standards for wireless charging systems. Standards initiatives the company is involved in include the SAE International, International Electrotechnical Commission (IEC), International Organisation for Standardisation (ISO), STILLE and China Automotive Technology & Research Centre (CATARC).
