Anyone with a cell phone, laptop or just about any other electronic device knows that battery chargers seldom work among different models – even when they are from the same brand.The SAE J1772™ Task Force is working to ensure that a similar scenario doesn't play out for electric cars.
The Society of Automotive Engineers and General Motors are trying to gain a consensus on a standard-sized plug for electric vehicles. The ubiquitous plug would enable a common plug for all OEMs to use for the future electric infrastructure. The standard plug would make an expansive infrastructure easier to tackle while saving EV owners the headache of worrying about different kinds of expensive adapters.

Beyond a standard plug, SAE J1772 is working to define physical, electrical and performance requirements so they can be manufactured for public use. The SAE will also find answers for basic questions about battery electrochemistry, size and life cycle.

GM's role in the standardization process has a lot to do with the Chevrolet Volt and future Volt variants. Since GM will likely have the first mass-market vehicle with electric-only propulsion, a plug standard ought to save The General time and money.
