Slashdot: will EV’s crash the grid?

Not only can EV’s be programmed to charge at night when the demand on the grid goes right down, but they don’t appear to demand all that much energy in the first place.

“Last week’s heat wave prompted another eruption of that perennial question: Won’t electric cars that recharge from grid power overload the nation’s electricity system? The short answer is no. A comprehensive and wide-ranging two-volume study from 2007, Environmental Assessment of Plug-In Hybrid Vehicles, looked at the impact of plug-in vehicles on the US electrical grid. It also analyzed the ‘wells-to-wheels’ carbon emissions of plug-ins versus gasoline cars. The load of one plug-in recharging (about 2 kilowatts) is roughly the same as that of four or five plasma television sets. Plasma TVs hardly brought worries about grid crashes.”

The US Department of Energy found that it would not take a single new power station to run every car in the USA as long as they charged at night.
