SAE International’s anticipated new revised technical standard for the combo coupler for plug-in hybrid electric vehicle (PHEV) and electric vehicles (EV) has been approved and published.
Developed in a consensus environment by more than 190 global experts representing automotive, charging equipment, utilities industries and national labs, “J1772: SAE Electric Vehicle and Plug in Hybrid Electric Vehicle Conductive Charge Couple” enables charging time 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. 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
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.
