The North American Charging System (NACS), standardized as SAE J3400, is an electric vehicle (EV) charging connector standard maintained by SAE International.[1] Developed by Tesla, Inc., it has been used by all North American market Tesla vehicles since 2021 and was opened for use by other manufacturers in November 2022. It is backwards compatible with the proprietary Tesla connectors made before 2021.

Between May 2023 and February 2024, almost all other vehicle manufacturers have announced that their electric vehicles in North America will be equipped with the NACS charge port, starting in 2025. Several electric vehicle charging network operators and equipment manufacturers have also announced plans to add NACS connectors.
