Stellantis announced this week that it will adopt the North American Charging System (NACS) in select all-electric vehicles in North America, Japan, and South Korea.

Additionally, it is expected for Stellantis to gain Supercharger access across the Tesla Supercharging network for all its EVs (currently more than 28,000 stalls across the impacted five countries — the United States, Canada, Mexico, Japan, and South Korea).

The group has multiple brands, including Jeep, Chrysler, Dodge, Ram, Alfa Romeo, and Fiat.

Stellantis NACS Adoption

Stellantis originally announced in February 2024 that the switch to the NACS (SAE J3400) charging standard would begin in North America in 2025. However, as we are now in November 2025, it seems that the use of NACS charging ports instead of CCS1 will begin in 2026. Stellantis’ electrification plans appear notably delayed and scaled back in general.

Additionally, Stellantis announced the international expansion of SAE J3400 use in Japan and South Korea. That’s a smart move, as Tesla already operates NACS charging infrastructure in both markets. At the same time, it makes little to no sense to develop special versions of its EVs with a CCS1 charging port just for South Korea and with a CHAdeMO charging port, just for Japan.

In other global markets, Stellantis is expected to stick with the CCS2 charging port.

Stellantis Supercharging Access

Gaining native access to the Tesla Supercharging network is the primary reason behind the switch to the NACS (SAE J3400). According to Stellantis, its EVs will gain access to over 28,000 Tesla Supercharging stalls in North America, Japan, and South Korea.

The manufacturer says that its compatible EVs will be able to charge at thousands of Tesla Supercharging locations in North America starting in early 2026. In Japan and South Korea, access is expected in 2027.

Stellantis’ existing EVs (like the Jeep Wagoneer S and Dodge Charger Daytona), equipped with the CCS1 charging port, will require a NACS-to-CCS1 adapter to access Superchargers. The upcoming 2026 Jeep Recon will most likely have a NACS charging inlet (it will need a CCS1-to-NACS adapter to access CCS1 chargers).

Update (December 1, 2025): We hoped for NACS, but the 2026 Jeep Recon is equipped with a CCS1 charging port.

Details about adapters and access will be shared later.

“Tesla Supercharger network availability will start in 2026 with existing North American BEVs, such as Jeep Wagoneer S and Dodge Charger Daytona, followed by the 2026 Jeep Recon and other future products.”

Overall, it’s good to see that Stellantis moves forward despite some delays. With access to the Tesla Supercharging network, DC fast-charging options significantly increase, as Tesla operates more than half of all public DC charging stalls in the US.

Stellantis also participates in other electrification efforts, including being a founding member of Ionna, a new, rapidly growing nationwide charging network in North America.
