Wireless electric cars about to hit the road

Imagine charging your electric car as easily as you charge your electric toothbrush.

Or, your car charging itself as it drives down the road.

Those scenarios are not as far-fetched as you may think. Indeed, a group of tech gurus who gathered last month in San Diego discussed how a wireless electric vehicle is about to become a reality.

“This is definitely coming,”

said Jesse Schneider, chairman of the wireless task force for the Society of Automotive Engineers, or SAE, an international group working to develop common standards to make sure the sector’s competing technologies work together.

Car buyers are familiar with plug-in hybrids and all-electric vehicles, but companies such as Qualcomm seek to jump-start the transition from internal combustion to zero-emission cars with “inductive” charging.

Instead of charging a vehicle with a plug or cable, the driver using a wireless system aligns the car over a charging pad and an electromagnetic field does the rest.

“Customers wait for the green light and then walk away, knowing when they come back they will be more fully charged or fully charged, depending on how long they were away,”

said Schneider.

“You can actually just park over the wireless charging system and everything is done automatically after that.”

The technology has been talked about for years but, starting with the hybrid version of the 2018 Mercedes-Benz S550e, wireless vehicle charging technology will make its debut. The German automaker reached an agreement with Qualcomm to use the San Diego-based company’s Halo technology as a feature on the luxury car.

New standardised wireless chargers mean cross-brand and network compatibility

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.”

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.”

Formula E Gets Wirelessly Charged Up

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.
