ABNewswire - Press Release Distribution Service: What Is NACS and Why It Matters

Electric vehicles are changing how we move and how we think about energy. As more drivers choose EVs, the need for a reliable ev charging solution becomes more urgent. Today, one of the biggest questions is whether the new NACS standard will shape the future of EV charging in North America. Car owners want faster charging, easier access, and a better experience at every NACS ev charging station. Manufacturers and every ev charger factory are working to solve these challenges by developing smarter and more unified systems.

The shift to NACS is not just a technical update—it's a major step toward making EV charging simpler for everyone. Instead of using different plugs and protocols, drivers may soon use a single connector across most brands. This could reduce confusion, lower costs, and speed up the expansion of charging networks. But there are still important questions: Will CCS disappear? How quickly will automakers make the switch? And how will charging infrastructure adapt?

In this article, we explain what NACS is, why it matters, and how it may impact EV owners, charging companies, and the entire ev charging station industry. Whether you are a driver, a business owner, or an ev charging solution provider, understanding this change is essential for the road ahead.

What Is NACS and Why It Matters

NACS means North American Charging Standard. It was first built by Tesla but is now becoming an industry-wide connector for electric vehicles. The reason it matters is simple: if most EVs use the same plug, charging becomes easier and faster—especially at every ev charging station across North America. Today, charging is often confusing because different connectors are used by different brands. With NACS, drivers may finally get a universal ev charging solution that works anywhere.

Why non-Tesla EVs need Tesla charging access

Tesla owns the largest fast-charging network in the United States. As of early 2025, over 89% of all NACS fast-charging ports are located at Tesla Supercharger sites (source: paren.app industry report, Q2 2025). That means non-Tesla vehicles cannot fully enjoy long-distance travel unless they can access Tesla stations. This is why automakers like Ford, GM, and Rivian are moving to build NACS-supported models and even partnering with every ev charger factory to speed up adapter production. For EV owners, access to Tesla infrastructure is often the difference between easy charging and range anxiety.

What is SAE J3400?

SAE J3400 is the official technical certification that turns NACS into an open standard. It ensures that the connector is safe, reliable, and compatible across different EV brands and charging equipment. J3400 also requires UL 2251 compliance, meaning every connector must meet strict safety rules before reaching any ev charging station. With this standard, charging equipment makers and ev charging solution providers can design products without worrying about proprietary limits.

How NACS changes the future of EV charging standards

NACS could lead to a single plug across most electric vehicles starting from 2025 onward, according to automaker announcements and industry forecasts. If successful, it may replace CCS and reduce manufacturing costs by 10–15% across ev charger factory production lines (source: transcript-iq.com industry analysis, 2024). More importantly, it could speed up the growth of charging infrastructure and create a unified ev charging solution for millions of future drivers. Instead of asking “Where can I charge?”, drivers may soon ask only one question: “How fast can I get there?”

Overview of NACS Charging Standard

The North American Charging Standard (NACS) is Tesla’s streamlined charging connector that supports both AC and DC charging in one plug. It was designed to be smaller, faster, and easier to use than existing standards — and today, it is becoming the new industry benchmark across the EV charging station and ev charging solution market.

Tesla's 2022 Release of the Connector Design

In 2022, Tesla officially opened its connector design to the industry, making it available for all manufacturers. Since then, over 20 billion miles of EV charging have been powered using this connector — proof of its reliability and real-world performance. NACS can support DC charging up to 1 MW, while remaining compact and easy to handle. (Source: Tesla, 2023) This release accelerated adoption and pushed NACS toward becoming the dominant standard in North America.

Existing Charging Standards (J1772 / CCS / CHAdeMO)

Before NACS, EVs mainly relied on J1772 for AC charging, CCS for fast DC charging, and CHAdeMO in earlier EV models. For example, J1772 supports up to 19.2 kW AC, while CCS adds extra pins to allow high-power DC charging. (Source: SAE Data 2024) However, the coexistence of multiple standards created confusion and slowed infrastructure growth for ev charger factory and EV manufacturers.

AC + DC Charging Capability of NACS

A major advantage of NACS is that it uses a single connector for both AC and DC modes, reducing hardware cost and making charging more user-friendly. Under SAE J3400 specifications, NACS can deliver up to ~80 A at ~277 V AC, and up to 500 A at 1,000 V DC, scalable to 1 MW in the future. (Source: Industry Reports 2024) This makes it compatible with both home chargers and public fast-charging stations.

Key Technology Difference — PLC vs CAN Bus

Unlike older Tesla connectors that relied on CAN bus, NACS now uses Power Line Communication (PLC). This allows smarter interactions between the vehicle and charging station — including plug-and-charge, software updates, and smart grid integration. PLC is also compatible with ISO 15118, making NACS a strong foundation for next-generation ev charging solutions and infrastructure development across North America.

Which Automakers Are Adopting NACS?

The shift to NACS (North American Charging Standard) is not limited to Tesla — many major automakers are now embracing this connector. With SAE’s standardization and broad infrastructure support, the industry is moving toward a more unified EV charging future.

Ford (2025 Transition)

Ford was one of the first big automakers to commit to NACS. The company plans to build all of its new EVs with the NACS plug starting in 2025, while offering adapters for earlier CCS-equipped models.

GM, Rivian and Early Adopters

General Motors is also on board: GM will switch its EVs to the NACS port by 2025 and make a CCS-to-NACS adapter available.

Rivian, similarly, has announced that its R1T and R1S models will use NACS by 2025, following adapter access in earlier years.

Full List of Major Brands Supporting NACS

Many additional automakers have confirmed they will adopt NACS (SAE J3400) in the coming years. These include Volvo / Polestar, Mercedes-Benz, Nissan / Infiniti, Honda / Acura, Hyundai / Kia, BMW / Mini / Rolls-Royce, Toyota / Lexus, Jaguar, Lucid, Fisker, and Stellantis brands.

SAE J3400 — NACS Becomes an Official Standard

NACS has been formalized as the SAE J3400 connector through a Technical Information Report published by SAE International.

This standardization makes NACS truly open: any EV maker or charging station operator can now build or use the same connector. The J3400 connector also requires UL 2251 certification, ensuring safety and interoperability across the industry.

Electrify America & Charging Infrastructure Support

Recognizing the shift, Electrify America has pledged to support NACS in its DC fast-charging network. According to its plans, EA will begin adding NACS connectors to both new and existing stations by 2025, while still maintaining CCS plugs.

This helps non-Tesla EV drivers access a broader, more flexible charging network using their NACS-equipped vehicles or adapters.

Joint-Venture Charging Network (30,000+ High-Power Stations)

A major infrastructure push is underway: IONNA, a joint venture formed by seven automakers (BMW, GM, Honda, Hyundai, Kia, Mercedes-Benz, and Stellantis), plans to build at least 30,000 high-power charging locations.

These chargers will support both CCS and SAE J3400 / NACS, enabling a truly multi-brand, future-proof ev charging solution network.

NACS and Tesla Magic Dock Explained

NACS and Tesla’s Magic Dock are key to unlocking Tesla’s Supercharger network for non‑Tesla EVs. While NACS provides the physical charging standard, the Magic Dock is a hardware adapter installed at certain Superchargers so that EVs using CCS (or other plugs) can connect. This setup bridges the gap between Tesla’s proprietary infrastructure and other EVs by offering a practical ev charging solution.

How Magic Dock Works

Magic Dock is a built-in adapter at some Supercharger stalls. When a non‑Tesla EV arrives, the Magic Dock sits on top of Tesla’s NACS connector, allowing the non‑Tesla vehicle to use the Tesla charging port. According to Tesla, this system is supported through their app and requires communication between car and charger before delivering power. Tesla has been retrofitting Supercharger sites to include Magic Dock units.

Charging Experience for Non‑Tesla EVs

For non-Tesla EVs, charging via Magic Dock is generally smooth but comes with conditions. The setup allows power delivery similar to native Tesla charging, potentially up to 250 kW, depending on the station. Car makers like Ford, Rivian, and GM are providing NACS or adapter‑based solutions so their drivers can take advantage of these Supercharger stalls. Many EV owners report the process is nearly seamless, but setup requires the Tesla app to start charging.

Limitations and Tesla App Usage

There are still some limitations. Not all Superchargers support Magic Dock — only a subset of stations have been retrofitted. Also, non‑Tesla EV drivers must use the Tesla app to begin and pay for their charge, even on Magic Dock stalls. Some users say the app interface is not always intuitive, and there can be idle or parking penalties if charging ends.

How to Locate Superchargers “Open to Other EVs”

To find Magic Dock–enabled Superchargers, EV drivers should use the Tesla app or Tesla’s online map and filter by “Superchargers Open to Other EVs.” According to collected data, over 40,000 Tesla Supercharger stalls are now open globally to non-Tesla EVs, with more than 20,000 of them in North America. This means it’s increasingly feasible for non‑Tesla EV drivers to plan long-distance trips using Tesla’s fast-charging network — especially at stations equipped with Magic Docks.

Using NACS with Adapters (Transition Phase)

During the transition to NACS, many non‑Tesla EVs still rely on adapters to connect to Tesla Superchargers. These adapters bridge the gap before manufacturers fully switch their vehicles and infrastructure over, offering a practical ev charging solution during the interim.

Why Adapters Are Needed Before 2025

Before 2025, many EVs are built with CCS ports and not yet native NACS. Adapters are necessary for non‑Tesla EVs to use Tesla’s Supercharger network. Ford, GM, Rivian, and other automakers have issued CCS-to-NACS adapters to ensure drivers can access high-speed charging.

Compatibility with Tesla V3/V4 Superchargers

These adapters are compatible with Tesla V3 and V4 Superchargers. They allow non-Tesla EVs to charge at speeds comparable to native Tesla vehicles, supporting both AC and DC modes under SAE J3400 standards.

Charging Power Specs (AC 80A / DC 500A)

Adapters enable AC charging at ~80 A and DC fast charging up to 500 A, with some capable of reaching 1 MW in future deployments. (evhype.com) This ensures high-speed access for long-distance travel.

Example Automakers & Adapter Strategies

Ford – Offered free adapters for early EVs, but faced delays and quality issues.

Rivian – Provides adapters but warns against unauthorized third-party versions; supply chain issues caused some delays.

GM – Adapter costs $225, purchased via the automaker’s app.

Lectron Vortex Plug – Third-party option priced at $199, rated for 500 A / 1,000 V, widely used but some early units recalled for latch issues.

These adapters ensure non‑Tesla EVs can access Tesla’s high-speed network during the NACS adoption phase, making long trips and public fast charging more practical.
