Tesla Opened the Connector on November 11, 2022. The Page Says System. Ford and GM Say Standard.

A connector design, a company agreement to use it, and a standards document are three different publications. Tesla’s November 11, 2022 post opens a design. It does not, by itself, make that design an SAE standard. The marketing page’s “by 2025” is a sentence still sitting on the site in October 2026. It is not a census of which cars shipped with which inlet.

The company is Tesla. Storage hardware is a different product: Megapack.

What’s confirmed

November 11, 2022: the post that opens the design

Tesla’s post, read October 20, 2026, is bylined “The Tesla Team, November 11, 2022.” The URL ends in opening-north-american-charging-standard. The heading on the page is “Opening the North American Charging System.”

The body says the Tesla charging connector has more than a decade of use and 20 billion EV charging miles, offers AC charging and up to 1 MW DC charging, has no moving parts, and is half the size and twice as powerful as Combined Charging System connectors. It says Tesla is “opening our EV connector design to the world” and invites charging-network operators and vehicle manufacturers to put “the Tesla charging connector and charge port, now called the North American Charging System (NACS),” on their equipment and vehicles.

It says NACS vehicles outnumber CCS two-to-one, and that Tesla’s Supercharging network has 60 percent more NACS posts than all the CCS-equipped networks combined. It says network operators already have plans to incorporate NACS, and that Tesla looks forward to future vehicles charging at its North American Supercharging and Destination Charging networks. It says the design is “a purely electrical and mechanical interface agnostic to use case and communication protocol,” and that Tesla is “actively working with relevant standards bodies to codify Tesla’s charging connector as a public standard.”

An update on the same page, printed as of September 30, 2024, says that because NACS is now recognized in an SAE recommended practice under SAE J3400, Tesla has removed the technical specifications and CAD from the website, and that the files are available within the SAE J3400 recommended practice. The foot of the page also says “Updated October 2025.” It does not say what changed in October 2025.

Label: Tesla’s post, including the later update printed on it. “Most proven,” “half the size,” “twice as powerful,” “two-to-one,” and “60% more” are the company’s comparisons on that page. This desk did not open a table that counts posts or vehicles. “Up to 1 MW” is the post’s capability sentence. The September 30, 2024 sentence is Tesla’s statement that an SAE recommended practice exists. The SAE document itself was not the file downloaded. The URL’s word is “standard.” The heading’s word is “system.” This page does not treat those as a single official name.

What tesla.com/NACS says now

tesla.com/NACS, fetched October 20, 2026, shows three stall figures: 36,500+ “Stalls for Teslas,” 25,000+ “Stalls for NACS,” and 2,400+ “Stalls for Other EVs.” The page does not date those counts.

It says Superchargers make up three out of four fast chargers and “have set the standard for EV charging in North America.” It says “this standard, known as the North American Charging System (NACS), has been adopted by all large automakers, with manufacturers and charge point operators transitioning to the NACS by 2025.” It lists supported names: Ford, Rivian, General Motors (GM), Volvo, Polestar, Nissan, Lucid, Mercedes-Benz, Hyundai, Genesis, Kia, Honda, Acura, JLR, Audi, Porsche, Toyota, Volkswagen (VW), Subaru, BMW, and Stellantis.

It says the network “continues to open to more automakers,” that drivers will gradually use adapters “provided by their automakers,” and that “soon, all new EVs will come with NACS charge ports built in.” It says that since 2012 Tesla has been building the charging experience, “achieving a 99.95% uptime,” and that Superchargers “were always intended to be made available to other EV drivers.”

Label: The current marketing page. “All large automakers” and “by 2025” are sentences on that page in October 2026. A sentence that says the transition is “by 2025” is not, on its own, a report that every listed company finished in 2025. The stall counts are unlabeled as to the day they were counted. The supported list is the page’s list of names. It is not a set of dates.

May 25, 2023: Ford’s release

The live Ford media URL returned 403 on October 20, 2026. The release was read from the Internet Archive capture of that URL dated December 26, 2023 (20231226195610). The captured page is the Ford Media Center release “Ford EV Customers To Gain Access to 12,000 Tesla Superchargers; Company to Add North American Charging Standard Port in Future EVs,” datelined Dearborn, Mich., May 25, 2023.

The release says Ford reached an agreement with “Tesla Motors” that will provide Ford electric-vehicle customers access to more than 12,000 Tesla Superchargers across the U.S. and Canada, “doubling the number of fast-chargers available to Ford EV customers starting Spring 2024.” It says a Tesla-developed adapter will give F-150 Lightning, Mustang Mach-E, and E-Transit vehicles with a CCS port access to Tesla’s V3 Superchargers. It says Ford will equip future EVs with the NACS charge port, “removing the need for an adapter for direct access to Tesla Superchargers, starting in 2025.”

Jim Farley, Ford president and CEO, is quoted on “12,000+ Tesla Superchargers plus 10,000+ fast-chargers already in the BlueOval Charge Network.” Rebecca Tinucci, “Tesla’s senior director of charging infrastructure,” is quoted welcoming “Ford owners, and other electric vehicles who adopt NACS.” The release says the BlueOval Charge Network has over 84,000 chargers, including access to over 10,000 public DC fast chargers.

Label: Ford’s May 25, 2023 release, as preserved in that archive capture. “North American Charging Standard” is Ford’s phrase. Spring 2024 and 2025 are the release’s schedule. They are not a later count of adapters delivered. “Tesla Motors” is the name in the release. “Doubling” is Ford’s comparison.

June 8, 2023: GM’s release

General Motors’ release, datelined Detroit, June 8, 2023, says GM announced a collaboration with Tesla to integrate the North American Charging Standard connector into its EVs beginning in 2025, and to expand access to 12,000 Tesla Superchargers, “and growing,” throughout North America. It says GM customers will be able to access those Superchargers beginning in early 2024. It says the network will be open to GM drivers starting in 2024 and will initially require an adapter. It says that beginning in 2025 the first GM EVs will be built with a NACS inlet.

Mary Barra, GM chair and CEO, says the collaboration “could help move the industry toward a single North American charging standard.” Rebecca Tinucci, here “Tesla’s Senior Director of Charging Infrastructure,” says Tesla is excited to work with GM “via the North American Charging Standard.” The release says the agreement builds on more than 134,000 chargers available to GM drivers through Ultium Charge 360. The release includes a forward-looking-statements caution. “Beginning in 2025” and “could” are the release’s words.

Label: GM’s release. Ford’s 12,000 and GM’s 12,000 are each company’s figure for Supercharger access in its own announcement. This page does not add them. Ford says “Spring 2024.” GM says “early 2024” and also “starting in 2024.” Those are the two releases. They are not a single date.

What the Joint Office prints about SAE J3400 and NEVI

The Joint Office of Energy and Transportation page on the SAE J3400 connector, fetched October 20, 2026, says that in December 2023 SAE International published the Technical Information Report for J3400, “an EV charging connector standard based on the North American Charging Standard (NACS) connector.” It says that in May 2023 the Federal Highway Administration published requirements that allow J3400/NACS adapters on all federally funded direct-current fast chargers “as long as there is also a CCS1 connector.” It says that in August 2024 the SAE EV Coupler Task Force voted to establish the J3400 standard as a Recommended Practice.

The same page, lower down, still says “SAE J3400: The SAE standard currently in development for the NACS connector,” and a timeline box says the recommended-practice document was “expected by September 2024.” Another section says that in June 2023 SAE announced a J3400 task force, and that the task force published the Technical Information Report in December 2023. On NEVI, the page cites 23 CFR 680. It says each DC fast-charging port must be capable of charging any CCS1-compliant vehicle and must have a permanently attached CCS1 connector, and that the final rule allows other “nonproprietary” connectors so long as each port can charge a CCS1-compliant vehicle. Its takeaway: federally funded chargers can include a J3400 connector if there is also a CCS1 connector that meets the rule.

A Joint Office news post dated September 12, 2024, SAE Task Force Votes to Establish J3400 Standard as Recommended Practice, says the task force “recently” voted to establish J3400 as a Recommended Practice, and that completion of the standardization process “is expected soon.” That post calls Tesla’s connector the “North American Connector Standard (NACS).” It does not print the word August.

Label: The Joint Office, on pages that do not all use the same tense. December 2023 is that office’s date for the Technical Information Report. August 2024 is the charging-connector page’s date for the vote. The September 12, 2024 post says “recently” and “expected soon.” Tesla’s blog update, dated on the blog as September 30, 2024, says the connector is recognized in an SAE recommended practice. This page does not collapse those into one publication day. SAE’s own press-room URL for a December 2023 announcement returned a shell without the release text. The SAE Mobilus page for J3400/2_202504 returned a cookie wall, not the standard. This page does not cite an SAE issue date it did not read on an SAE page.

The May 2023 FHWA sentence and the 23 CFR 680 description are the Joint Office page’s. The Federal Register rule was not the document opened. “Nonproprietary” is the page’s word for the connectors the rule allows in addition to CCS1. A permission to add a connector is not a requirement that every federally funded charger have one.

Claims and open questions

“Twice as powerful,” “two-to-one,” and “60% more” remain the November 11, 2022 post’s comparisons. The current NACS page’s stall counts are undated. “Adopted by all large automakers” is that page’s sentence.

Ford’s and GM’s 2025 inlet dates were plans in the 2023 releases. This page does not audit which 2026 model years have which port. The supported-automaker list on tesla.com/NACS is longer than Ford and GM. The other names on that list were not each matched to a release this desk opened.

The Joint Office page’s “currently in development” line and its “expected by September 2024” line were still on the page when it was fetched. They are not erased by the August 2024 sentence higher up, and they are not reconciled here.

On the map

Tesla is the company. The October 21, 2026 financial report is not out on the Q3 page. Energy storage is Megapack. The companies map is the section.
