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.

Tesla CEO Elon Musk said the company will remove “safety monitors” from the passenger seats of Tesla’s Robotaxi vehicles in “about three weeks,” which would mean we’d see completely driverless Teslas in the Austin area potentially by the end of the year – if that timeline sticks.
Tesla has been working on a system that would allow vehicles to drive themselves, which has been in “beta” release for over a decade now. It calls this system “Full Self-Driving,” despite the fact that the system does not currently drive itself.
That has not stopped Musk from consistently promising more and more of the system, despite its stagnating capabilities. Over the course of the last decade, Musk has consistently promised driverless vehicles within the coming year, with deadlines consistently passing by without achieving that goal.
One of those promises has been the creation of a driverless taxi network, which Tesla used to call “Tesla Network” and is now calling “Robotaxi.” The idea originally came with the promise that owners could use their cars to make money by running them as taxis, but that hasn’t panned out.
Tesla did roll out its own version of a taxi network, though, in Austin, in June of this year. While it’s done a few cool things, the cars each have a “safety monitor” in the passenger seat who can take control at any time, which means the cars aren’t truly “driverless” since there is an operator, they’ve just been moved to the passenger seat.
In the time since Robotaxi’s rollout, it’s made quite a few mistakes and had a high crash rate. But Tesla also delivered one fully unoccupied vehicle from the factory to a local buyer, which was a cool (and, as yet, still unique) stunt.
Throughout the year, Musk has claimed loudly that the system would improve rapidly, stating that by the end of the year Robotaxis would be available to half of the US population (they are not) and that Tesla’s fleet would grow by more than 10x by the end of the year (it has not).
But now we have another bold prediction from Musk, stating that the safety monitors will be out of a job by the end of the year.
During a videoconference at a hackathon event for xAI, one of Musk’s other companies (which he is trying to get Tesla shareholders to bail out), Musk was asked a question about the barriers to unsupervised full self-driving. Musk answered:
Unsupervised is pretty much solved at this point. There will be Tesla Robotaxis operating in Austin with no one in them, not even anyone in the passenger seat, in about three weeks. I think it’s pretty much a solved problem, we’re just going through validation right now.
The “three weeks” timeline is familiar to longtime Tesla followers. Over the years, Musk has often promised fixes or software updates in “two weeks,” and they often take longer than that.
Three weeks is a lot closer than the “next year” promise that we’ve heard so many times for full autonomy, but given its proximity to the oft-inaccurate two-week timeline, we’re not sure these vehicles will actually be ready in time for New Year’s Eve celebrations.
Nevertheless, it’s a closer timeline than Musk has usually given, so there may be truly driverless Teslas operating sometime soon™.
Also, reading the statement more closely, it sounds like they won’t necessarily remove safety operators from every vehicle, but some vehicles. This could be similar to the singular driverless vehicle delivery that Tesla did – a PR stunt, rather than a full rollout. We’ll have to wait and see.
Tesla’s main competitor in the robotaxi space is Waymo, which has been operating truly driverless vehicles for several years now. The company has also been operating autonomous, driverless vehicles in Austin since March of this year.
Musk went on to talk about future improvements to Tesla’s software and hardware in his answer.
The company is currently on hardware previously deemed HW4, though to cash in on the AI stock market bubble, it now refers to that system as AI4. He said that AI5 will be 10-40 times better than HW4 and go into volume production in 2027, with AI6 coming soon after.
Musk’s mention of future hardware improvements neglects one important aspect of these improvements, which is that for every hardware improvement Tesla puts into its fleet, the more vehicles it will have to upgrade later.
Tesla long promised that its vehicles had all the hardware for self-driving, which means it’s going to have to upgrade a lot of cars – and there are court cases around the world seeking to force the company to do so. Together, these lawsuits and other potential challenges could mean billions of dollars in liabilities for the company.
Musk then closed his statements by claiming that “our” goal is to “to understand the meaning of life and… propagate consciousness out to the stars,” which is not Tesla’s goal. Tesla’s actual goal is to accelerate the transition to sustainable energy. He may have been referring to xAI’s goal, but given the answer was about Tesla, perhaps he was confused (or perhaps he doesn’t care about Tesla anymore, and isn’t a good CEO for the company as a result…)

VW’s retro-tastic minivan hasn’t been the sales success the company might have wanted, and a lot of that has to do with the van’s sky high price tag. Now, VW is asking: will a $10,000 discount be enough to create some buzz for the ID.Buzz?
Volkswagen is offering $7,500 in Retail Customer Bonus cash this month – up from the $2,500 the company offered its Black Friday customers – that, along with an additional $2,500 unadvertised dealer cash incentive that CarsDirect is reporting absolutely, definitely exists, adds up to a stout $10,000 total discount on the all-electric VW ID.Buzz … and that’s before you start haggling with your dealer over the MSRP.
It’s a lot
As much as I like the the Volkswagen ID.Buzz, its starting MSRP around $61,545 (incl. destination) puts it at nearly twice what you’d probably expect a minivan to cost if the last time you shopped for one was at a Dodge store. Still, that hefty price tag is some $20,000 higher than the baseline Toyota Sienna hybrid or Honda Odyssey.
That 50% higher price is a lot to swallow even if you do buy into the nostalgia. Still, the ID.Buzz is capable enough, and with ~230 miles of range and 282 hp on offer from its battery/electric motor combo – plus Supercharger access – it’s at least able to keep up with the minivan competition.
So, while that $10,000 discount isn’t going to turn the ID.Buzz into the second coming of the affordable, family-hauling Caravan, it does bring VW’s electric people-mover a little closer to earth. In fact, with a $50K price tag, it’s right in line with the average transaction price of a new vehicles. So, if nothing else, that reduced price could finally gives electric minivan buyers something to buzz about (I tried so hard to work that in, you guys).
If you’ve been shopping for a family-hauler and dig the retro vibe over something like the (excellent) Kia EV9, click through the link below and set up a test drive at your local VW dealer.

Peterbilt has jumped into the MD truck ring with the launch three new medium-duty electric trucks that deliver zero-emissions power, ultra-fast 350 kW charging, and proven, versatile platforms for delivery, utility service, and vocational upfitting.
The new Peterbilt 536EV, 537EV, and 548EV medium-duty trucks slot into the same versatile medium-duty segments the company’s fleets already know, but swap diesel power for latest PACCAR ePowertrain, with up to 605 hp and 1,850 lb-ft of torque available at 0 rpm. That big motor draws power from a variety of LFP battery packs and be fitted with ePTO options rated for either 25 kW (two-battery option) or 150 kW (three-battery option), making them suitable for that can be sized for daily delivery routes, urban utility work, and municipal fleets looking to cut both emissions and maintenance costs.
What’s more, the new Peterbilt’s flexible architecture allows for integration with existing PACCAR suspension bits to make 4×2 and 6×4 configurations, and any wheelbase of 163 inches or longer, and up to 82,000 lbs. gross combined weight ratings possible.
“[The new trucks are] optimized for the demands of the medium duty segment, the next generation of Peterbilt electric vehicles deliver excellent efficiency, rapid charging and versatile configurations elevating customer productivity across a wide range of applications,” said Erik Johnson, Peterbilt assistant general manager, Sales & Marketing.
In addition to all those goodies, the PACCAR EV tech continues to be top-notch, with the previously-mentioned 350 kW charging, regenerative braking, and industry-leading ergonomics.
Peterbilt’s new MDEVs ship with a blue accented crown and grille for a distinctive exterior look, as well as EV-exclusive panels on the side of the hood. The interior design features laser-etched trim panels on the EV-exclusive Magneto Gray interior, just in case the driver in the quiet, smooth, and stink-free cabin forgets they’re in an electric truck.
Electrek’s Take
Ignore the headlines. The death of the commercial EV market simply hasn’t happened, and won’t happen any time soon.
If you believe the engineers and analysts at MAN Trucks and Orange EV (and, you should), an EV like this can pay for itself in reduced fuel and maintenance costs even without incentives, then you should already know what I’m about to say: the future of trucking is 100% electric.
