Fast-Charging “Combo” Coupler Standard Published by SAE
October 15th, 2012 by Zachary Shahan
A new technical standard for plug-in hybrid electric vehicle (PHEV) and electric vehicles (EV) has been approved and just published today by SAE International, “a global association of more than 133,000 engineers and related technical experts in the aerospace, automotive and commercial-vehicle industries.” The SAE International standard is a huge step forward for EV and PHEV charging.
“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‘ enable charging time to be reduced from as long as eight hours to as short as 20 minutes,” a news release on the new standard stated.
“The standard represents the future of charging technology and smart grid interaction, while addressing the needs of today. Such needs include reduced times at public charging stations, enabling consumers to travel greater distances in their PHEV’s and EV’s.”
There are a handful of big steps that we need to take in order to find ourselves in an EV-abundant world, and developing better, mass manufactured charging stations is arguably one of them. It’s exciting to see so many talented people working together to help move this side of things forward.
“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,” Gery Kissel, Engineering Specialist, Global Battery Systems, GM, and SAE J1772™ Task Force Chairman, said. “We now can offer users of this technology various charging options in one combined design.”
“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.”
Here’s a bit more from the news release:
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.
