The Last Piece Falls Into Place
Stellantis, the multinational automaker behind Jeep, Dodge, Ram, Fiat, Maserati, and Chrysler, has officially gained access to Tesla's Supercharger network for its electric vehicles. With this addition, virtually every major electric vehicle sold in America can now use the Supercharger network — the largest DC fast charging infrastructure on the continent with over 20,000 stalls at thousands of locations.
Stellantis was the final major automaker to complete the transition to NACS — the North American Charging Standard originally developed by Tesla — making this milestone the effective end of a multi-year standardization process that has reshaped the EV charging landscape. Owners of qualifying Stellantis EVs will need a NACS adapter to connect at Supercharger stations until new models ship with native NACS ports.
How the Industry Got Here
Two years ago, the American EV charging ecosystem was fragmented across two incompatible connector standards: Tesla's proprietary NACS and the CCS used by virtually every other automaker. The fragmentation was a genuine barrier to EV adoption — prospective buyers had legitimate concerns about finding compatible fast chargers on long road trips.
The transformation began in May 2023 when Ford announced it would adopt NACS for future vehicles and allow existing Ford EV owners to use an adapter at Tesla Superchargers. General Motors followed weeks later, triggering a cascade of announcements from Rivian, Volvo, Polestar, Honda, Nissan, Mercedes-Benz, and eventually every major automaker. The Society of Automotive Engineers subsequently ratified NACS as an official standard, giving it the industry backing needed for widespread infrastructure investment.
What It Means for EV Drivers
For consumers, the practical benefit is straightforward: a dramatically expanded charging network accessible from any new or recent EV with the appropriate adapter or connector. Tesla's Supercharger network has consistently outperformed competing networks on reliability, speed, and density of coverage along major highways — advantages that were previously exclusive to Tesla owners.
Supercharger V3 stations charge at up to 250 kW, delivering several hundred miles of range in under 30 minutes for compatible vehicles. The newer V4 stations support up to 500 kW for peak performance. By comparison, many third-party fast charging networks have struggled with reliability, offline stations, and slower speeds at equivalent price points.
The Broader Charging Picture
The NACS adoption sweep doesn't mean EV charging infrastructure is fully solved. Network reliability remains inconsistent outside of Tesla's network, and charging density along rural corridors still lags behind gas station coverage. But the standardization of NACS removes one major obstacle: the connector compatibility problem that made long-distance EV travel a planning exercise in network geography.
With a single adapter, virtually any EV can now access the most reliable fast charging network in the country — a significant quality-of-life improvement for current owners and a meaningful reassurance for prospective buyers. The completion of the Stellantis transition also marks a quiet but significant defeat for the CCS standard — Tesla's early investment in charging infrastructure has ultimately driven the industry to adopt its connector as the continental standard.
