LONDON – Qualcomm Inc. (San Diego, Calif.) has announced it has agreed to apply its wireless electric vehicle charging (WEVC) technology to Renault vehicles as part of an upcoming trial.
Qualcomm calls its WEVC technology Halo and it is set to be used in a London trial. Renault SAS has joined the trial steering committee. The objectives of the trial are to evaluate the commercial viability of wireless EV charging and gain user feedback on the use of WEVC-enabled vehicles.
In addition, Delta Motorsport Ltd. (Towcester, England), an automotive and motorsport engineering consultancy, has agreed to integrate Halo into its Delta E-4 electric vehicles, for deployment in the London WEVC trial in the second half of 2012. Addison Lee, the UK's largest minicab company, and Chargemaster plc, the leading European operator of electric vehicle charging infrastructure, have also agreed to participate in the WEVC London trial.
The technology is based on inductive charging across the air gap between a transmitting pad in the road surface and a receiving pad on the underside of a vehicle. It typically works at frequencies below 300-kHz but the final details are not yet decided and subject to standards negotiation. It is not yet clear whether the technology uses simple inductive magnetic coupling or resonant inductive coupling. The technology is also said to be suitable for in-motion charging in circumstances where electric-roadways are set up.
For parked charging the ground pad remains switched off until a vehicle with a compatible pad is in proximity. The two pads include wireless communications which carry authentication, charging requirements and payment negotiations prior to charging beginning.
Qualcomm acquired the technology along with assets of HaloIPT Ltd. (London, England) in November 2011. HaloIPT's technology was based on 20 years of research into wireless power at the University of Auckland in New Zealand.
The objectives of the trial are to evaluate the commercial viability of the wireless charging of electric vehicles (EVs), to develop a further understanding of issues relating to the integration of WEVC technology into EVs, to build knowledge associated with the deployment of WEVC into a megacity, and to gain user feedback on the use of WEVC-enabled electric vehicles.
"The deployment of wireless inductive charging requires inter-operability between cars and ground systems within common European and, hopefully, worldwide standards," said Jacques Hebrard, vice president at Renault, in a statement from Qualcomm.
Hmm... wireless charging sounds pretty cool. But that is a lot more energy in the air than that of radio, Satellite, or cell phone signals, isn't it?
I am more interested in see the environmental and healthy study results of the impact of the wireless charging signal on human body. Cancers?
Reminescent of the Scaletrix race car game where toy cars were powered through copper brushes that sat in a metal track.
The plug-together race-track usually had two such tracks and shaped in a figure of 8 with single bridge to make the distance to travel the same for both cars.
Instead of wireless charging using the charging pads, if this technology can be extended to have conductive guide way on the road itself , using which one can directly drive the EV ( no need to charge) then that I could call a pulling factor to go for EVs. The on board batteries will be used only on the road patches where there is no such conductive guide way.
There is an argument that if it is less efficient in energy transmission that conducted charging it would be irresponsible to deploy it.
You would be trading convenience today for global warming tomorrow.
I am sure this technology will find some applications
Joshua Smith gave an excellent plenary on this topic at emerging technologies meeting in Vancouver last week, www.cmoset.com
But I am skeptical in applications of battery charging
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
