Germany’s major car manufacturers support HomePlug Powerline Alliance GP Specification for plug-in charging network interface

The top five German car manufacturers—Audi, BMW, Daimler, Porsche and Volkswagen—working together as the Coordination Office Charging Interface, have chosen to support the Home Plug Alliance’s IEEE 1901 Profile Green PHY (GP) as the technology for the charging network interface of plug-in electric vehicles. HomePlug GP is a low-power, cost-optimized powerline networking specification targeting Smart Grid applications such as HVAC, smart meters, home appliances and plug-in electric hybrid vehicles.

Additionally, HomePlug has invited the participation of these auto manufacturers in developing the HomePlug Green PHY certification program. The HomePlug Powerline Alliance serves as a compliance and certification body for IEEE 1901 (broadband over powerline—BPL—networks) and manages the largest compliance and interoperability certification program for powerline networking products.

New modulation techniques offer the possibility to use the power lines for high speed communications. The IEEE 1901 standard for broadband over powerline networks covers both medium access control and physical layer specifications.

For electric vehicles to be widely accepted, they must integrate into existing and emerging charging infrastructures, connected to the smart grid. For charging electric vehicles, the communication interface is established via the charging connector, and the HomePlug Green PHY provides a common communications standard to support all modes of AC and DC charging.

—Dr. Heiko Doerr, Manager of Coordination Office Charging Interface

Utility companies and manufacturers are looking to adopt communications and networking technologies, such as HomePlug GP, to help consumers and businesses monitor and reduce their energy consumption. HomePlug GP is a key component of the HomePlug technology portfolio, along with HomePlug AV broadband powerline technology and the upcoming HomePlug AV2 specification. HomePlug AV is the baseline technology for the IEEE 1901 powerline standard; HomePlug GP is derived entirely from HomePlug AV. Therefore, HomePlug GP is completely interoperable with HomePlug AV and IEEE 1901. They are designed to make it easier for multiple chip suppliers and manufacturers to deliver products to support IP networking.

The announcement comes on the heels of recent research reports from In-Stat, Infonetics and Pike Research pointing to the continued leadership of the HomePlug technology standard around the world. Pike Research analyst Bob Gohn commented, “The adoption of standards is a key driver to widespread smart appliance adoption, and our research indicates that HomePlug Green PHY is likely to be the power line standard that gives manufacturers the confidence to rollout products in increasingly greater numbers.

With HomePlug technology, the electrical wires in the home can now distribute broadband Internet, HD video, digital music and smart energy applications. The HomePlug Powerline Alliance, Inc. (www.homeplug.org) is an industry-led initiative with 65 member companies that creates specifications, marketing and certification programs to accelerate worldwide adoption of powerline networking with HomePlug technology.

Sponsor members include Broadcom Corporation; Cisco; Duke Energy; GE Energy, an affiliate of General Electric Co.; Qualcomm Atheros; Renesas Electronics Corporation; SPiDCOM Technologies; and STMicroelectronics.




That's fine.
As long as there are no subscription fees, middlemen, or other sources of revenue that are skimmed off the top of my electrical bill when I am plugging my own car into my own home outlet. None - ever.
A pretty little power network attachment is no reason to believe that the Utility is providing me with any additional service or item with which they can make money.


This is another smokescreen piece of marketing from the German OEMS to try to distract everyone from how far behind they are relative to the OEMs that are making real plug in cars today. They are several years behind the leading companies after having not taken electrification seriously until about last year. "vee have de diesel, vhy do we need de hybrid?" was the word from the teutonic intelligensia from 2000 to 2010.

Where are the herr doctors now? "vee have picked a specification framework for a shaky physical communication connection totally unnecessary in a gps enabled wirelessly connected world."


These are private companies. If there are subscription fees, middlemen, or other sources of revenue that are added to the top of your electrical bill when U R plugging your car into your own home outlet it will be because your government was lobied into allowing it.

Fear immoral government - not immoral industry.
Industry must compete; (except for GM, GE, Microsoft although their “effective monopoly” is a matter of opinion).
Don't like what OEMs offer, don't buy it.

Indeed German OEMS are late embracing EVs, BUT, there is nothing ahead to be behind.

What are EV/BEV/hbrid sales these days? 5%?
Toyota enjoyed the admiration of the fiscally challenged for swimming upstream for 10+ years, while others drove along the shore (in their SUVs and turbo-diesels).

Where would we be today if GM had continued the EV1, Honda the Insight-I, Toyota the eRav and Toyota NOT made the Prius – right where we are.
No difference.
Lift-off awaits a better battery.

GM was maybe not too soon back in, but only because EVs remain the darlings of the dreamers and will soon shift from fun value to real value – so GM aims to capture the “image”.
