The HomePlug Powerline Alliance announced today that German auto manufacturers Audi, BMW, Daimler, Porsche, and Volkswagen have agreed to support HomePlug's Green PHY standard for electric-vehicle charging technology.
HomePlug is a technology that turns electrical wiring into data cable, hence eliminating the need for a separate set of wires for networking. Currently the most popular application of the power-line technology is in HomePlug AV-based devices used for home power-line networking, such as the
According to the HomePlug Powerline Alliance, the power-line standard that the five German car manufacturers--"after intense case studies and tests"--are supporting is "support for Smart Grid. The HomePlug Powerline Alliance describes it as a "a low-power, highly reliable and cost-optimized power-line networking specification" that helps connect different "applications such as as appliances, smart meters, climate control, and plug-in electric hybrid vehicles" via the existing electric wiring.," which was finalized in June 2010 and enables faster networking speeds as well as
This means that in the future electric-car owners will be able to easily manage and monitor their cars' power consumption and charging on the same IP network as other devices in the home.
