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.”
Next generation Mercedes S-Class plug-in hybrid flagship to get clever new charging system, while diesel PHEV will join it
The facelifted Mercedes-Benz S-Class plug-in hybrid will feature high tech wireless charging, according to Jochen Strenkert, Mercedes’ man responsible for hybrid powertrains.
Speaking to Auto Express before the Geneva Motor Show, Strenkert revealed that Mercedes is working in collaboration with arch rival BMW to develop the new tech, sharing the high cost of the new system.
We’ll see the new S-Class plug-in hybrid in summer 2017, while the car will feature Mercedes’ latest third generation hybrid powertrain, boasting a bigger battery pack.
“We already have a working prototype,” Strenkert revealed, adding that “battery capacity is predicted to double every five years, so the next S-Class plug-in will also have an increased range.”
Here you can see how wireless electric car charging works and the benefits of wireless charging. When this new technology is rolled out to the masses it will change everything with regards to the way people feel about having to charge an electric car.
Four plug-in BMWs will be support vehicles (safety, medical, etc.) for the all-electric Formula E racing series. These 4 vehicles have now been fitted (or will be soon) with Qualcomm Halo wireless charging technology.
Per Formula E:
All four BMWs have been specifically modified to meet FIA requirements, with one of the BMW i3 models featuring an inductive charging system from Qualcomm Incorporated, with the remaining three vehicles set to be adapted at a later stage. The technology has been developed by San Diego-based Qualcomm Incorporated, one of the official Founding and Technology Partners of the series and a global leader in 3G, 4G and next-generation wireless technologies. The Qualcomm Halo™ technology uses resonant magnetic induction to transfer energy between a ground-based pad and a charging pad fitted to the underside of the vehicle. The cars can then simply park over the base pad for charging to start automatically.
