What is V2G?

Electric-drive vehicles, whether powered by batteries, fuel cells, or gasoline hybrids, have within them the energy source and power electronics capable of producing the 60 Hz AC electricity that powers our homes and offices. When connections are added to allow this electricity to flow from cars to power lines, we call it "vehicle to grid" power, or V2G. Cars pack a lot of power. One typical electric-drive vehicle can put out over 10kW, the average draw of 10 houses. The key to realizing economic value from V2G is precise timing of its grid power production to fit within driving requirments while meeting the time-critical power "dispatch" of the electric distribution system.

News

On September 21, 2009, Delaware's Governor Jack A. Markell signed Senate Bill 153 (left photo), making it law (right). The bill, which is the first of its kind in the world, requires electric utilities to compensate owners of electric cars for electricity sent back to the grid at the same rate they pay for electricity to charge the battery. The event was held at AutoPort Inc. near the Port of Wilmington, where that same day, the first electric car built in Delaware, and the first car ever with complete V2G controls built-in from the factory, rolled off the line (see regional economy). For more information see SB 153 and the UDaily Press Release. EV World Insider described this law as “...the most progressive piece of electric vehicle-focused legislation to date.” The article is available here with permission from the editor.
