SAE International will standardize the Tesla-developed North American Charging Standard (NACS) connector. This will ensure that any supplier or manufacturer will be able to use, manufacture, or deploy the NACS connector on electric vehicles (EVs) and at charging stations across North America.

Ford Motor Company, General Motors, Rivian, Volvo Cars (earlier post) and a number of EV charging companies recently announced plans to adopt the NACS connector through adaptors or future product offerings.

The standardization process is the next step to establish a consensus-based approach for maintaining NACS and validating its ability to meet performance and interoperability criteria. The Joint Office of Energy and Transportation was instrumental in fostering the SAE-Tesla partnership and expediting plans to standardize NACS—an important step in building an interoperable national charging network that will work for all EV drivers.

The new SAE NACS connector standard will be developed on an expedited timeframe and is one of several key initiatives to strengthen the North American EV charging infrastructure. This includes SAE-ITC’s Public Key Infrastructure (PKI) for cyber-secure charging. In close cooperation with National Labs, SAE also is contributing to reliability design for the national ChargeX consortium.
