Tesla Supercharger fast-charging system for electric cars
German automakers and their U.S. counterparts are working on closely related (although not identical) fast-charging standards that build on the J-1772 coupler. The U.S. version of that standard is known as the "SAE Combo" connector, but the first cars to use it--let alone any fast-charging stations for it--will not hit the market until 2013 or 2014.
While this standards war is consuming the electric auto industry, the average car buyer has more pressing concerns.
How fast? How far? How much?
The answer to those questions isn’t found in the charger plug.
“Unless the industry zips up and starts getting serious about making electric vehicles, all the chargers in the world won’t give drivers a happy ending,” Sexton concludes.
