The Society of Automotive Engineers (SAE) recently announced that it will work to further standardize the North American Charging Standard (NACS) electric vehicle connector. The announcement follows the news that GM will adopt the NACS for new GM EVs starting in 2025. The NACS was originally developed by Tesla.
“Standardizing the NACS connector will provide certainty, expanded choice, reliability and convenience to manufacturers and suppliers and, most of all, increase access to charging for consumers,” said president of Sustainable Mobility Solutions, Frank Menchaca. Sustainable Mobility Solutions serves as an innovation arm of SAE affiliate Fullsight.
The SAE stated that standardization will be developed on an expedited timeframe, and that the process is required to establish a consensus-based approach “for maintaining NACS and validating its ability to meet performance and interoperability criteria.” The arrangement is considered one of several key initiatives needed to strengthen North American electric vehicle charging infrastructure.
SAE also indicated that it is cooperating with the U.S.’s network of National Laboratories and contributing to charger reliability design for the national ChargeX consortium, which also has commitments to participate in place from OEMs like GM, Ford, Stellantis, and BMW of North America, plus charging companies like Electrify America, Chargepoint, and EVgo.
Earlier this month, GM announced it would adopt the NACS starting in 2025, with GM CEO Mary Barra highlighting the need for collaboration in pursuit of an all-electric future and mass EV adoption. The announcement also included the news that GM EV owners would have access to more than 12,000 Tesla Supercharger stations throughout North America starting in early 2024. GM’s announcements followed similar announcements from Ford, which said that Ford EV customers would also be granted access to the Supercharger network, and that future Ford EVs would also gain an NACS port.
