SAE’s NACS certification is ready, and it’ll fix every EV charging problem at once
SAE has followed through on its plan to finish its NACS certification by the end of the year, and the NACS standard is now ready to go. And the new standard promises to solve a lot of charging problems in one fell swoop.
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, since Tesla is a majority of the US EV market, 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.
This led SAE, the professional engineering organization which develops industry standards, to take 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.
How NACS will solve several EV charging problems at once
We had another chat with Rodney McGee, Ph.D., of the University of Delaware, who chaired SAE’s NACS task force, and told us that the new standard will soon be announced by the White House. He was understandably excited about the standard getting finished so quickly, and told us how NACS is going to solve a lot of problems with EV charging all at the same time.
In particular, it should make charging installation cheaper for commercial entities, leading to cheaper and easier charging for businesses (including, potentially, for large apartment buildings); make charging more interoperable between commercial and personal vehicles; and unlock new possibilities for street charging for electric vehicles.
The main reason for this is the standard is preserving NACS’ support for 277 volts, as opposed to the 208-240 voltage of J1772. This simple change unlocks a cascade of benefits that should smooth out several charging problems.
Why does this matter? 277V is one phase of a three-phase 480V supply, which is the form that most commercial utility connections come in (particularly those that support DC chargers). Which means that secondary step-down transformers are no longer necessary for AC chargers, making EV charging installations cheaper and more efficient.
When you make EV charging installations cheaper and easier for businesses, this means more chargers at workplaces, giving people who can’t charge at home another option. It means more opportunity charging at any other place you might happen to park, and more opportunity charging means more EVs plugged in at any given time which means more battery capacity available on the grid in a potential V2G future.
Saving businesses money is all well and good, but the most important point here is that by making commercial installations cheaper, this means that mixed-use apartment buildings can more easily install banks of EV chargers, without needing big transformer rooms to further step down voltages. And that means that more people will be opened up to the convenience of having a charger at the place where their car spends the most time.
The news is even good for people who don’t have a parking spot – city-dwellers who use street parking. The NACS standard includes a provision that would enable the installation of chargers in lampposts, something that we’ve seen trials of in London. There have been similar efforts in the US, but those are subpar because the J1772 standard requires a permanently-attached cable, which means that streetside cables get dropped, broken, laid around, and otherwise abused.
The new NACS standard instead uses a standardized receptacle – which is in fact the same one used in the EU and China – which can be plugged into with a ~$100-200 carry-along cable that EV drivers can keep in their car (and the receptacle does have a locking mechanism). Making each driver responsible for their own cable makes maintenance easier in public spaces where otherwise, nobody’s really willing to take ownership of ensuring cables don’t get abused.
NACS also allows AC and DC through the same connector, unlike J1772. CCS is similar to the J1772 plug, but with an additional two pins on the bottom, so the connectors aren’t identical. With NACS, the connectors are identical for both types of charging.
Another potential upside here involves medium and heavy duty vehicles, which could charge at up to 52kW AC from the same receptacle as a light duty vehicle can charge at 20kW, by using 3 phases or 1 phase respectively. 20kW can be a bit on the low side for some larger vehicles – school buses and the like – so allowing those vehicles to charge at up to 52kW from the same place light duty can charge at 20kW would be a big boon as well.
And finally, all of these boons add together to a world where it’s easier to install and maintain chargers, and easier for everyone to be using those chargers wherever they’re parked, which means more cars plugged in at any given time. And if everyone is plugged in all the time, that means more capacity available for a potential vehicle-to-grid future. If V2G ever takes off, we will want to have as many cars plugged in as possible, because more cars plugged in means more capacity available for the grid. And that means making AC infrastructure cheap, which is what 277V support and carry-along cables enable.
There is one potential problem on the horizon, though: California and the US federal government (through NEVI) have both put a lot of money into charging station deployment, and the original intent of that money was to install roadside DC chargers that are as compatible as possible. So now, will those rules fully embrace NACS and allow the money to be used to install the new standard, or will they require CCS-compatible deployments so as not to leave an installed base of vehicles behind, even though CCS is now, effectively, a dead standard? (one compromise option being discussed is to require CCS for DC chargers, but throw full weight behind NACS for AC chargers)
This decision point is also a little ironic, since NACS’ existence seems to have been spurred on by NEVI in the first place. When the government offered billions of dollars to companies that install chargers with the restriction that those chargers be useable with multiple vehicles, that’s what got Tesla to finally offer a “standard.” At the time, it wasn’t really a standard because only Tesla was using it, and it was somewhat of a last-ditch effort to save the Tesla connector. Then, when Ford decided to use NACS, that’s what started all the others dominos falling. Now, NACS is dominant, but it only happened because of NEVI in the first place – and NEVI now has the difficult decision over whether to embrace the (positive) situation it caused, even if it will give some of the installed base an effective “use-by” date as a shift to NACS will inevitably mean fewer CCS/J1772 chargers over time.
Electrek’s Take
We’re actually pretty amazed that this standardization process finished already. SAE intended to finish by the end of the year, but standards can take a long time and require a lot of cooperation from organizations with differing motivations.
Part of why this process could be finished so quickly is because we’re now further into the world’s electrification journey, and auto manufacturers, many of whom now have departments getting into the charging business, can see the benefit of making charger installations cheaper.
And while we may have been a little hyperbolic in the title, this really does fix one of the few real problems with electric cars right now. There are a lot of perceived problems with EVs which rely on misconceptions, but one that isn’t a misconception is that there are bigger hurdles to owning an EV for people who don’t have a garage.
With cheaper AC charger installation benefits allowing better charging options for workplace, garage and street parking, this all adds up to a win for environmental justice. It makes EV charging easier for renters, or for people who otherwise do not have access to their own garage/off-street parking where they can install a charger. And that means more EVs in lower-income communities, and cleaner air too.
This has been a problem for a long time, and some piecemeal solutions have been proposed and are in the works, but this standard should help make that problem more solvable.
Ironically, the one thing the standard doesn’t solve is the problem we pointed out in the headline of our previous article on this – Plug & Charge. That article laid out how authentication issues are holding Plug & Charge back from being as good as it could be in the US, and unfortunately the SAE NACS standard (which it calls J3400) won’t solve that. However, work is ongoing on a solution for that problem, in a separate proceeding, and it seems like the NACS changeover may be the impetus needed to get it solved once and for all.

Bojangles, the North Carolina-based chain known for its fried chicken and biscuits, is joining the growing list of fast food chains installing EV chargers in their parking lots.
The restaurant chain is working with Smart Big Box, Alyath EV, and Energy and Environmental Design Services to install turnkey EV charging stations at a “wide range” of its 800 restaurants, which are concentrated heavily in the southeast US. The rollout starts in late 2025, with most chargers expected to be available by sometime in 2026.
Each Bojangles location getting EV chargers will offer at least four ports. The stations will vary between Level 2 and DC fast chargers.
Bojangles CIO Richard Del Valle said, “Working with Alyath and Smart Big Box allows us to introduce a new convenience that aligns with evolving customer needs.”
It’s a smart move. The charging stations will let people plug in and power up, and they’re more likely to dine at Bojangles while they’re doing so. Plus, Bojangles will get a reputation for having charging stations, so EV drivers will be more inclined to head toward the restaurants as a reliable power source.
Cristiane Rosul, CEO of Alyath, said the partnership “not only benefits EV drivers but also positions Bojangles as a leader in the future of quick-service dining.”
Smart Big Box has contracted with Energy and Environmental Design Services as the exclusive installer and maintenance partner for all EV chargers.

Toyota’s electric SUV is now its cheapest vehicle to lease. After slashing lease prices again, the Toyota bZ4X is listed for lease at just $199 per month in some states. That’s even cheaper than a Corolla right now, even though it’s nearly double the price.
Toyota bZ4X is now cheaper to lease than a Corolla
The 2025 Toyota bZ4X already starts at $6,000 cheaper than the previous model year, but with a new promotion this month, it’s even more affordable.
Toyota is at it again, having cut lease prices once more this month following the Fourth of July holiday. The 2025 Toyota bZ4X XLE is now listed at just $199 per month for 36 months. With $3,999 due at signing, you’ll end up paying an effective cost of $310 per month.
The offer is $42 less than before the new promo, or about a 12% price cut. It’s hard enough to find any lease nowadays around $300, but for an electric SUV, it’s a pretty good deal.
According to online auto research firm CarsDirect, it’s even cheaper to lease a bZ4X now in some states than a Toyota Corolla. The 2025 Corolla LE Sedan is available for $229 for 36 months. With $2,999 due at signing, the effective monthly rate is $312, or $2 more than the bZ4X.
Although $2 might not seem like much in the grand scheme of things, it’s pretty significant, given that the bZ4X is $16,000 more expensive.
The 2025 Toyota bZ4X XLE has an MSRP of $38,465, compared to the Corolla LE Sedan, which starts at $22,325. That’s a $16,140 cost difference alone.
Toyota’s electric SUV is slightly longer than a RAV4 at 184.6″ in length, but it has a longer wheelbase, which opens up more interior space.
Toyota is also throwing in a free year of unlimited charging (at EV-go-operated public charging stations) for those who buy or lease a new 2025 bZ4X. You can also add a ChargePoint home charger to the cost.
Although the bZ4X is available for just $199 per month, the 2025 Hyundai IONIQ 5 is listed at $179 nationwide this month. With more range, style, and an NACS port for charging at Tesla Superchargers, the 2025 IONIQ 5 offer is hard to pass up right now.
| 2025 Toyota bZ4X trim | Starting Price (excluding $1,395 DPH fee) |
Price reduction (vs 2024MY) |
Range (mi) |
| XLE FWD | $37,070 | -$6,000 | 252 |
| XLE AWD | $39,150 | -$6,000 | 228 |
| Limited FWD | $41,800 | -$5,380 | 236 |
| Limited AWD | $43,880 | -$5,380 | 222 |
| Nightshade | $40,420 | N/A | 222 |
Like many carmakers, Toyota is currently offering significant incentives on electric vehicles, with the federal tax credit set to expire at the end of September. Accordingly, Toyota’s promotion ends on September 30. Although the bZ4X doesn’t qualify for the credit through purchase, Toyota is passing it on through leasing.
In some areas, like LA, Toyota is currently offering $12,000 off bZ4X leases. With the loss of the tax credit, the savings would drop to just $4,500, which would add over $100 a month to the lease price.
Looking to take advantage of the savings while they are still here? You can use our link to find deals on the 2025 Toyota bZ4X in your area today.

Transport Canada has finished its investigation into Tesla’s questionable filing of $43 million worth of EV incentives in a single day, finding that the claims did indeed represent cars sold before the deadline to file for incentives – still raising questions about disorganization within Tesla.
To recap, Canada suddenly sunsetted its electric vehicle incentives back in January, as the program ran out of money. It caught a lot of EV dealers by surprise, and there was a sudden rush to sell cars and to file for incentives, given that the end of the program was announced with just three days notice.
One of these dealerships that showed a rush was a single Tesla dealership in Quebec, which recorded 4,000 rebate requests in a single weekend, an impossible number at the relatively small location. Other Tesla locations also filed for suspiciously high numbers of incentive claims on the same weekend.
This raised alarm bells, and other Canadian auto dealers pointed it out to Transport Canada, with Huw WIlliams, head of the Canadian Auto Dealers Association (CADA) claiming that Tesla “gamed the system” to hog an illegitimate number of incentive claims out of the limited money left. The total amount was $43 million, which was more than half of the amount left in the Canadian government’s coffers.
Even accounting for Tesla delivery pushes, and for increased sales as the credit rapidly sunset, these numbers did not seem possible.
This – perhaps combined with Tesla’s unpopular position in Canada at the time given CEO Elon Musk’s participation in a US government which was attacking Canada’s sovereignty at the time – led to Transport Canada announcing an investigation into Tesla’s incentive claims (Canadian Transport Minister Chrystia Freeland even said at the time that future Canadian ZEV incentives should exclude Tesla until the US’ “illegitimate and illegal” tariffs were lifted).
Tesla responded to the investigation in a typically standoffish manner, claiming in a letter that it was “shocked” to hear about the investigation, threatening legal action if payments weren’t resumed, and blaming Transport Canada for causing Tesla’s negative public perception and exposing Tesla’s Canadian employees to harassment (the letter did not, however, mention anything about CEO Musk’s government activities, or his recent actions attempting to spread white supremacy around the globe, and how those are much more responsible for negative public perception of the company).
Well now, the result of that investigation is back, and Freeland said on Friday that Tesla’s claims “were determined to legitimately represent cars sold before January 12.”
Transport Canada also pledged to CADA that all cars delivered before January 12 will have their incentive claims fulfilled, regardless of the program’s budget. CADA estimates it’s owed around $11 million in past-due claims, and Williams still wonders how Tesla knew to file those claims so suddenly.
Electrek’s Take
Questions still remain about this incentive. As pointed out by the Canadian Press, it’s still not clear whether Tesla’s incentive claims were for cars sold on that weekend, or for cars sold prior to that weekend and delivered all in a lump.
Given the physical limitations of the locations involved, it’s likely the latter. Which raises a different kind of alarm bell: that of disorganization within Tesla, as I pointed out as my main concern over this situation in a previous article.
I just don’t see how Tesla Canada can justify leaving tens of millions of dollars on the table for potentially several months, when all it took was the filing of some pieces of paper for them to get it. That’s capital that Tesla could have used to do business, and letting it sit in someone else’s bank account doesn’t benefit Tesla at all.
Now, disorganization is nothing new for Tesla, but businesses usually don’t like leaving money laying around for no reason. And Tesla, with its focus on quarterly results and end-of-quarter pushes, surely would have enjoyed having that extra cash in December, the end of a fiscal quarter/year, rather than the beginning of January when they filed for these incentives.
So regardless of the now proven legitimacy of these claims, this aspect should be cause for some amount of concern. It’s a reflection of a longtime problem in Tesla, where things tend to fall through the cracks until there’s some sort of emergency, and then it’s all-hands-on-deck from whoever happens to be closest to the problem at the time. But this has been an issue within Tesla for so long that it’s hard to see it being fixed at this point – and certainly not under its longtime CEO who seems far more interested in using Tesla to bail out his private companies or turning Twitter into “MechaHitler” than on making actual good decisions for Tesla.
