SAE J2954 is a standard for wireless power transfer (WPT) for electric vehicles led by SAE International. It defines three classes of charging speed, WPT 1, 2 and 3, at a maximum of 3.7 kW, 7.7 kW and 11 kW, respectively. This makes it comparable to medium-speed wired charging standards like the common SAE J1772 system.
The technology was also being used for the McLaren Speedtail Hyper-GT by 2020. [20] [34] In May 2020, China published their national standard for EV wireless charging which incorporated WiTricity's technology, [35] [36] and WiTricity played a key role in establishing SAE International's J2954 standard for wireless power transfer.

Commercialization of the technology has not been successful, leading to controversy over the continued public funding of the technology in 2019. [6] The technology was selected as one of Time's 50 best inventions of 2010. [7] [8] KAIST and Electreon have been working on a standard for dynamic wireless charging in 2021 [9] and 2022.
Cybex International was founded in the late 1960s as "The Cybex Ergometer Company" in Ronkonkoma, New York. It was acquired by Lumex, which was traded publicly on the American Stock Exchange. At that time, it manufactured isokinetic rehabilitation equipment. In 1995, Lumex sold its medical supply business and changed its name to Cybex (AMEX ...
Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices.
