The North American charging standard is now well on its way to reaching nationwide acceptance, as Stellantis finally embraces Tesla’s NACS charging connector. Stellantis has confirmed the upcoming switch to the proposed SAE J3400 connector charging connector (the Tesla-developed NACS plug) for its battery-electric vehicles in North America.

According to Stellantis, which has multiple brands like Jeep, Chrysler, Dodge, Ram, Alfa Romeo, and Fiat, we will start seeing the SAE J3400 in select models in 2025, in the 2026 model year versions of new all-electric cars.

The models fitted with a Combined Charging System (CCS1) charging port will be able to use SAE J3400 charging points via an upcoming adapter. Such a solution will be available during the transition period, the company explains.

Stellantis’ February announcement differs from the ones issued by other automotive groups because it does not mention Tesla or its Supercharging network. It appears that Stellantis intends to use the open industry standard once it is fully released without any direct agreements with Tesla.

Meanwhile, Stellantis (together with six other major global automakers) is developing its own public fast-charging network in North America, which was recently named Ionna. The first Ionna stations are to be installed later this year, with a plan to deploy at least 30,000 by 2030. Ionna chargers will be compatible with CCS1 and SAE J3400 (NACS) standards.

Ricardo Stamatti, Stellantis’s SVP of global energy & charging, said:

“Customers win when the industry aligns on open standards. We are happy to announce our backing and adoption of the SAE J3400 connector, a milestone for all customers on the path to open and seamless charging. Our Dare Forward 2030 strategic plan puts customers at the center of open interoperability and freedom of mobility for all. This future will be amplified by IONNA, our public charging joint venture with six other OEMs that will deliver industry-leading high-powered charging for all battery-electric vehicles regardless of brand.”

With Stellantis on board, nearly all major automotive groups and multiple smaller brands have signed up to adopt the Tesla-developed North American Charging Standard (NACS), which will soon be standardized as the SAE J3400. Because it is an industry-wide movement, within a decade or two, we should see a gradual fade of SAE J1772 and SAE J1772 Combo 1 (Combined Charging System / CCS1) charging solutions in North America. All AC and DC charging scenarios of light-duty electric vehicles and plug-in hybrids can be handled by the J3400.

Here are the OEMs that have previously confirmed the switch (in chronological order): Ford, General Motors, Rivian, Volvo, Polestar, Mercedes-Benz, Nissan, Fisker, Honda (with Acura), Jaguar, Hyundai, Kia, Genesis, BMW Group (BMW, MINI, and Rolls-Royce), Toyota (with Lexus), Subaru, Lucid, Volkswagen Group,and Mazda.
