SAE International publishes SAE J3400/2 Standard
SAE International has published a new standard, SAE J3400/2—Connectors and Inlets for the North American Charging System (NACS) for Electric Vehicles. Developed by SAE’s Hybrid-EV Committee, the new standard defines the physical architectural and mechanical specifications of the EV connector and inlet. SAE J3400/2 standardizes the physical architecture of EV connectors and inlets using 2D mechanical drawings and 3D modeling. This gives OEM and charging equipment engineers the specifications needed to develop interoperable hardware.
“The publication of SAE J3400/2 as an SAE International standard represents our confidence in the maturity of the 1,000-volt-capable NACS coupler for reliable and safe bidirectional power transfer,” said Dr. Rodney McGee, Chairman of the SAE J3400 NACS Task Force. “During our open-to-the-public meetings, our group will continue to lead the development of industry-led vehicle standards.”
“By standardizing these mechanical details, J3400/2 allows manufacturers to design and deploy EV charging infrastructure more rapidly,” said Christian Thiele, Sr. Director, Global Ground Vehicle Standards, SAE International. “The broader J3400 standard also ensures system-level consistency, covering communications, AC/DC power delivery, cybersecurity and vehicle-to-everything (V2X) capabilities.”
