The United States government is set to endorse Tesla's North American Charging Standard (NACS) as the federal EV charging standard.

Federal agencies will soon issue updated guidance to incorporate NACS into federally funded EV charging projects, known as the J3400 standard.

This update will clarify the use of NACS within the National Electric Vehicle Infrastructure (NEVI) program, which currently mandates CCS ports for federally funded chargers.

Kristin White, Acting Federal Highway Administrator, confirmed this significant shift during the Alliance for Automotive Innovation conference.

SAE International has finalized the NACS design under the designation J3400, establishing it as an open standard that is not exclusive to Tesla.

This transition to NACS will operate within existing regulations, thereby avoiding the need for new rulemaking.

The evolution of NACS from a proprietary Tesla design to a federal standard illustrates the collaboration between industry stakeholders and regulatory bodies.

This standardization has received widespread support from automakers and charger manufacturers.

The endorsement of NACS aims to unify the nation's EV charging infrastructure, enhancing compatibility, efficiency, and accessibility for electric vehicle users.

To provide further information, a webinar and FAQs about these changes will be released on December 17, 2024.
