All Aboard! Stellantis Last Major Automaker to Adopt Tesla Charging Standard

Just shy of one year after Tesla first announced that it would open its Supercharger network of DC fast chargers to electric vehicles from other automakers, the last major automaker in the U.S. has committed to incorporating Tesla’s charging port into its EVs. Stellantis — the parent company of Alfa Romeo, Chrysler, Dodge, Fiat, Jeep, Maserati and Ram — will begin building EVs with the Tesla charging port in 2025.

Tesla calls its charging port — and the compatible plug — the North American Charging Standard, or NACS. The technically and regulatorily minded know it as SAE J3400, its official designation by SAE International. Regardless of what you call it, the NACS port and plug are much smaller and lighter than the alternative, the SAE J1772 Combined Charging System, which is what most other EVs sold in the U.S. use.

Skipping the Wait

But as Level 2 charging infrastructure continues to advance to meet the local needs of EV buyers, DC fast charging remains the largest hurdle to long-distance EV travel. (Level 2 chargers add a rate of about 20 miles of range per hour — depending on the vehicle — while DC fast charging can be 10 times as fast or more.) Stellantis is among the six automakers who signed a joint agreement in 2023 to develop a fast-charging network, now named Ionna, with the goal of installing as many as 30,000 chargers in major metropolitan areas and the major travel arteries, connecting them by 2030.

Stellantis’ announcement, however, means that buyers of the upcoming Dodge Charger, Jeep Wagoneer S and the automaker’s other future EVs will have access to a vast network of DC fast chargers at launch. With approximately 24,000 individual plugs in the U.S., Superchargers make up more than half of the existing DC charge points in the country. Dodge and Jeep have yet to reveal full information on their EVs, but with their 800-volt electrical architecture, DC fast-charge times from 10%-80% are likely to be around 30 minutes.

With Stellantis set to begin production of the Charger and Wagoneer S for the 2025 model year but the NACS implementation not taking effect until the 2026 model year, the company will make adapters available for early buyers of its EVs that allow them to connect the NACS plug to their CCS charge port.
