SAE approves new fast-charging standard for EVs, plug-ins
October 15, 2012
SAE International said it has approved a new technical standard that will dramatically reduce charging times for plug-in hybrid electric vehicles and electric vehicles.
After several years of study, the global engineering group said the new charging standard, developed with the cooperation of more than 190 automakers, utilities and equipment builders, will allow charging times to be reduced from as long as eight hours to as short as 20 minutes.
"This new standard reflects the many hours that top industry experts from around the world worked to achieve the best charging solution -- a solution that helps vehicle electrification technology move forward," said Gery Kissel, an engineering specialist with General Motors' Global Battery Systems unit and head of SAE's charging task force. "We now can offer users of this technology various charging options in one combined design."
The original charging standard defined AC Level 1 and AC Level 2 charge levels and specified a conductive charge coupler and electrical interfaces for AC Level 1 and AC Level 2 charging. SAE says the revision incorporates DC charging where DC Level 1 and DC Level 2 charge levels, charge coupler and electrical interfaces are defined.
Next year, GM will introduce the Spark EV that will feature the fast-charging system.
