SAE wants to certify NACS by end of year, and fix plug & charge too
SAE has voted unanimously to form a task force to expedite its NACS standardization process, and thinks that this process could finish by the end of the year – much earlier than we expected. We spoke with the chair of the task force for some insight on what the process might look like.
Tesla released specifications of its charging connector in November 2022. It called it the “North American Charging Standard,” which was somewhat of an absurd name at the time, given that Tesla was the only company using it.
However, Tesla’s argument was that most of the cars and most of the DC charging stations in America already used Tesla’s connector, so it should be considered a de facto standard anyway.
For a few months not many people took this seriously, until Ford shook up the industry by announcing it would adopt the NACS plug on upcoming vehicles. Soon after, GM made the same move, and now basically everyone else has.
So now that we have what looks like a standard, the professional engineering organization which develops industry standards has taken up the flag of creating a real, independent standard that is no longer in the hands of Tesla.
This is an important move because many governments and companies would understandably have an issue with a single company having control over a standard that, at this point, it seems like everyone is planning to use.
NACS standard could come this year, named “J3400”
We talked to Rodney McGee, Ph.D., of the University of Delaware, who is chairing SAE’s NACS task force.
The most important thing he told us is that the SAE Task Force aims to publish its work by the end of this year, only around six months after the start of the standards process. This is significantly faster than we thought it would take to complete the process.
McGee said that SAE is the only standards-setting organization that would be able to publish NACS this quickly, because the timelines for meetings and consensus in the ISO and IEC, two other standards organizations, are much longer due to the complex document processes used by these international organizations.
Another reason for this quicker timeline is because the NACS connector already exists on millions of vehicles, and makes up the majority of the installed base in the US. Since their stations are listed to UL standards and have been proven in the real world, many questions are already answered.
The standard will likely take the official name “J3400,” similar to the name of the current J1772 plug used in SAE CCS chargers. Though it could colloquially be known as J3400, NACS, or even “the Tesla plug,” depending on which name the EV-owning public seizes on.
But McGee told us that this his interest in NACS isn’t just on the DC side of charging, where most of the public’s imagination has focused, but on AC charging where the vast majority of actual charge sessions occur. It turns out that NACS is superior to J1772 for AC charging in one significant way – it can use an input voltage of up to 277 volts, whereas J1772 uses 208-240V.
This not only enables faster AC charging due to higher voltages, but more importantly makes for easier setup on commercial electricity supplies, which is often supplied as 480-volt three-phase power, of which a 277-volt single-phase circuit can be used for charging. This could make public AC charging – in parking garages for apartment buildings or workplaces, for example – cheaper and easier to install since commercial customers won’t need to install their own transformers.
McGee said that Tesla has been very helpful with the process in the last two weeks since SAE proposed making NACS a real standard, and is leaving the future of NACS up to a consensus-based standards process.
This has helped to allay some concerns across the industry, especially in Europe, which was skeptical that NACS could be a protectionist move. Europe has mandated non-proprietary charging connectors before and recently wasn’t happy about EV protectionism in the US Inflation Reduction Act, so this recent groundswell of support for a standard controlled by one American company was met with some skepticism. Having a standards-setting organization in control of the future of NACS makes it much more palatable (and might have led to Mercedes’ announcement to adopt it last week).
Why Plug & Charge is broken and how to fix it
Plug & Charge, a colloquial name for the ISO 15118 standard which allows simple “plug in & walk away” operation of public charging stations, has had a long and difficult implementation process. For years charging station providers have promised it’s just around the corner, but it seems to never materialize.
This is part of why Tesla leads in charging experience satisfaction, because plugging into a Supercharger is a simple process that takes seconds, whereas other chargers might require a subscription, a payment app, swiping a credit card, or at the very least waiting the better part of a minute for authentication to occur before charging initiates.
Besides these user experience issues, McGee pointed out one of the lesser-discussed reasons the standard has been hard to implement in the US, and how the SAE has been working on that problem since before NACS, and sees NACS as a opportunity to further its effort.
Plug & Charge requires a Public Key Infrastructure on the back-end to authenticate vehicles and payments. Public keys are a cryptographic mechanism that allow for secure authentication – one example is website certificates, so your computer can know that it is looking at a legitimate website.
In Europe, this PKI is provided by a company called Hubject, which verifies charging sessions on European public chargers.
But in the US, nobody has coalesced around a single company or organization to provide these certificate services yet. McGee said this is a major obstacle to Plug & Charge in the ISO 15118 standard, first published in 2014, since it is a technical standard did not initially prescribe solutions that were practical for the market.
SAE participants see the wider efforts around the NACS process as an opportunity to solve this problem going forward. Since the industry is shifting to NACS, this disruption could serve as the right time to solve this problem. It is engaging with industry (through SAE-ITC) to create a PKI for NACS which will hopefully solve this problem going forward.
Electrek’s Take
We were surprised to hear that NACS could be certified as a standard by the end of this year.
In the past, standards have taken much longer to develop – in fact, that’s why we even have the Tesla plug in the first place.
When Tesla was building the Model S, there wasn’t a standard that could do both AC and fast DC charging in the same plug. The rest of the industry – and the SAE – was slowly working out the CCS standard, but Tesla couldn’t wait any longer and went its own way, building the Tesla plug and later revealing the Supercharger network.
Now, more than a decade later, that Tesla connector looks likely to become the main charging standard in North America.
So the idea that this could be approved by the end of the year definitely raised our eyebrows, given the history of charging standards implementation and sometimes-long timelines involved.
And we’ve had a lot of questions about Plug & Charge and how long it has taken to implement in the past, so the conversation with McGee was enlightening on that front. It’s good to hear that a solution might finally be around the corner.
But this is a bit of a double-edged sword – while the NACS disruption gives an opportunity to solve the Plug & Charge problem for NACS, increased focus on the new charging standard might mean that nobody bothers to fix it for CCS, as it rapidly becomes considered a “legacy standard” the likes of CHAdeMO.

Volkswagen is putting its Tesla Robotaxi rival through its paces in Wolfsburg, Germany, where the self-driving Gen.Urban research vehicle is now driving autonomously in real urban traffic – without a steering wheel or pedals!
VW’s Gen.Urban research project sets out to explore how passengers experience riding in a self-driving vehicle on real roads, among real drivers, and without a traditional steering wheel or pedals, and what those requirements might mean for future vehicle concepts.
Some of the key questions VW is asking include:
- How do people spend their time in a self-driving vehicle?
- Which digital features best support work, entertainment, or relaxation?
- How should interaction between the vehicle and passengers be designed, particularly for older people or children?
- Most importantly: Do people feel comfortable?
“The technology for autonomous driving is making rapid progress,” explains Dr. Nikolai Ardey, Head of Volkswagen Group Innovation. “With our Gen.Urban research vehicle, we want to understand exactly how passengers experience autonomous driving. Because: The key to a positive customer experience is to build trust – through meaningful interaction, a relaxed atmosphere, and intelligent assistance systems that respond precisely to the needs of passengers. Ultimately, technology should fit people, not the other way around. We will benefit from these insights across the entire Group in the long term.”
Not QUITE fully autonomous
It’s important to note here that, while Volkswagen designed the Gen.Urban without a steering wheel or pedals, the vehicles participating in these test have a trained safety driver monitoring the vehicle from the passenger seat, ready to step in to control the vehicle using a specially developed control panel with a joystick – which means we’re still a long way from the 2022 Volkswagen Gen.Travel concept (above).
Even so, Volkswagen’s autonomous driving efforts have been in public testing phases since at least 2023, when the company unveiled a fleet of ten specially modified VW.Buzz AD electric vans. Tests with those vans have gone well enough, at least, to lead Volkswagen to announce plans for large-scale production.
The current test phase is limited to Volkswagen Group employees as riders, and is planned for a period of several weeks. If results are satisfactory, VW could expand its rider base by the end of Q1.

Ask anyone who owned or owns one, and they’ll tell you that Honda Element was ahead of its time, delivering a flexible interior, car-like ride, and SUV-levels of visibility – and, if Honda really wanted to, they could roll out an all-new, all-electric Element riding on an Ultium-style electric skateboard tomorrow.
Honda’s first Element made its debut way back in 2003, when it was still a bit strange to think of companies like Cadillac, Volkswagen, and Porsche selling anything as big and clunky as an SUV. It earned plenty of fans, however, and for all the same reasons, they’ll love an electric Element even more.
Consider the following:
Car-like handling
The original Element rolled around on a lot of bits originally developed for the Honda Civic – widely regarded as a fun-to-drive, great-handling little car. That car-based chassis earned it some mockery among automotive journalists who, more than two decades ago, still widely believed that an SUV had to have some off-road chops to it.
Today, we’re a more enlightened bunch. In 2025, an SUV needs to be practical above all else, emphasizing the “Utility” aspect. With a low-slung, low-cg, and low-intrusion electric skateboard underneath its boxy body (more on that in a minute), a modern Element would be than more than capable of delivering a “car-like” ride with plenty of sporty acceleration, as well.
Flexible interior
Remember that comment about the low-intrusion nature of the Ultium EV chassis? Without a transmission tunnel to get in the way, Honda was able to offer a massive, flat floor that made the Element ideal for moving, camping, beach days, tailgating, antiquing, and (not to put too fine a point on it) drive-in movies – which we still had those in Florida until at least 2010.
In an EV, all that flat-floor goodness is still there, with the added benefit of being able to offer a flat floor without a transmission tunnel ruining the bedroom cargo bay.
Add a bit of extra width inherited from the Prologue, toss in a friendly ASIMO interface to keep the investment class happy, and offer a full range of inflatable tents, dog beds, and other overlanding, pet, or surf-friendly accessories, and Honda could watch the money roll in. At the very least, if Honda had built a modern Element instead of the Prologue on GM’s skateboard, they might have an easier time moving them in post-rebate America, I think. What do you guys think?
You guys are smart, so I’m sure you’ll be able to find all the problems with this particular take – and I can’t wait to hear them! Should it be FWD only? A plug-in hybrid? Ship with a tent? Scroll on down to the comments and let me know what you think it would take to make a battery-powered Honda Element revival make sense to you.

File this under “wishful thinking” if you want, but a fresh trademark filing for the Buick Electra name could mean that the storied nameplate is set for a return to US shores.
GM Authority reports that Buick parent company General Motors has renewed its trademark for the Buick Electra name in the US in a filing from 09DEC2025 with the United States Patent and Trademark Office (USPTO), and received an assigned serial number 99538079. The application carries a Goods and Services of, “Motor land vehicles, namely, automobiles.”
Electra a nameplate that holds a long history with the near-luxe Buick brand and has generally been believed to be one that’s especially relevant to Buick’s electrification strategy in the US. That’s a notion that seems especially true when you consider the following two facts:
- the Buick Electra nameplate is already featured on a number of hugely successful GM products being sold in the ultra-competitive Chinese market
- 2027 is the fortieth anniversary of the Buick Grand National, and GM’s marketers are way too smart to let that moment slide
It’s worth noting, of course, that this most recent renewal for the Buick Electra trademark is a long, long way from a confirmation of a new all-electric Buick for the US market and even further from a confirmation that we’re getting the hot, sexy Electra GM sells in China. If anything, it’s likely just a matter of course legal thing that GM needs to protect its IP in China while, at the same time, preventing some kind of disastrous Sierra Mist scenario from playing out at home (which– yeah, I get that it’s not true, but you got the idea).
That said, I want to believe.
Electrek’s Take
I’m a huge fan of GM, GM’s EVs, and the way Mary Barra has managed the General over the past several years. I also think a big, sexy sedan is sorely missing from GM’s lineup, and the fast, flashy electric sedan formula might play better at the Buick store than at the Cadillac brand.
Combine that with an overwhelming desire to see a new-age Buick Grand National parked in my garage next Christmas and you can see that I’m not to be trusted. So, what say you? Head on down to the comments and let us know what you think of an American Electra revival just in time for the 2027 model year.
