Wireless EV Charging Standard Agreed

The world’s major electric car makers and charging equipment providers have agreed on a standardised specification for wireless EV charging points, allowing companies to develop components going forward that will seamlessly work with each other anywhere.

Although not as exciting on the surface as say a new high-powered rapid charger, the standardisation of wireless car charging is of vital importance to the EV market in the future.

All of the main EV and PHEV manufacturers are planning on incorporating wireless charging into future models, while it is also a crucial element of autonomous EVs that can drive off and charge themselves when not in use.

The new SAE J2954 standard will charge at either 3.7 kW or 7.7 kW in Level 1 or Level 2 respectively. These use current commonly found charging rates, with a Level 3 set-up charging at 11 kW planned for later this year.

The agreements were made at a meeting at Audi HQ in Ingolstadt, Germany, chaired by Jesse Schneider who has worked on the project since 2010.

Mr Schneider said:

“Charging your vehicle should be as simple as parking it and walking away — and wireless charging with SAE J2954™ enables that freedom and convenience to do this automatically. Automakers believe that wireless charging can greatly help to make both electrified and autonomous vehicle mainstream, and they have been active supporters of our standardization efforts.

“Reaching a decision for a common J2954™ RP test station, equipped with circular topology, provides automakers with the technical direction for their wireless charging system design, development and production release plans to meet industry compatibility, interoperability and performance standards. It is a major step forward for the industry.”
