WARRENDALE, PA - SAE International published its technical standard for plug-in hybrid electric vehicles (PHEVs) and electric vehicles (EVs). "J1772: SAE Electric Vehicle and Plug in Hybrid Electric Vehicle Conductive Charge Couple," which can reduce charging times from as long as eight hours to as short as 20 minutes, the organization stated.
"This new technical standard is a real game-changer," Andrew Smart, director of Industry Relations and Business Development for SAE International, said. "It reflects the advancements in technology within PHEV and EV engineering and we are pleased to represent the collaborative efforts within industry that made it possible."
The standard was developed in a consensus environment by more than 190 global experts representing automotive, charging equipment, utilities industries, and national labs. It represents the future of charging technology and smart grid interaction, while addressing today’s needs, such as reduced times at public charging stations to allow consumers to travel greater distances in their PHEVs and EVs.
"We now can offer users of this technology various charging options in one combined design," Gery Kissel, engineering specialist, Global Battery Systems, GM, and SAE J1772 Task Force Chairman, said.
The original version of J1772 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. The new revision incorporates DC charging where DC Level 1 and DC Level 2 charge levels, charge coupler, and electrical interfaces are defined. The standard was developed in cooperation with the European automotive experts who also adopted and endorsed a combo strategy in their approach.
