EVs: North American Charging Standard

[Dr Mordrid]

The only two car makers remaining to sign on are are Volkswagen and Stellantis

Also,

BP and LG have signed on to buy white label and produce Superchargers, respectively.

Nissan has joined the NASC adoptees. VW and Hyundai are still evaluating, and some others may wait until the SAE finishes their publication which is on an accelerated schedule.

[Dr Mordrid]

Now three states are requiring nacs in order to get charger subsidies; Washington, texas, and now Kentucky. More on the way. With state's chiming in and SAE involved it seems to be a done deal.

Volkswagens Electrify America subsidiary will be including NACS in their Network. It remains to be seen if North American Volkswagen vehicles will use the socket.

It is quite a long section of highway

We have no long sections of highway. I would not be surprised if or highways have the highest density of highway ramps and exits. But yes, if license plate recognition works well now at reasonable cost then that could work I think.

I wonder what this will mean for private imports... In Poland you sometimes - more often than in Belgium - see imported US cars (recognizable as either the models are not sold here, or the indicators are different even if the colour was changed). I'm not talking about manufacturer imports for the other market, but just private ones.
Europe is going full CCS, US apparently are going NACS. I know there are conversion possibilities, but still... I wonder if manufacturers don't see some added benefits in isolating the markets that way.

SAE International Announces Standard for NACS Connector, Charging PKI and Infrastructure Reliability

2023-06-27

Key Initiatives Contribute to Interoperable, Secure and Reliable EV Charging

WARRENDALE, Pa. (June 27, 2023)*– SAE International today announced it will standardize the Tesla-developed North American Charging Standard (NACS) connector. This will ensure that any supplier or manufacturer will be able to use, manufacture, or deploy the NACS connector on electric vehicles (EVs) and at charging stations across North America. Ford Motor Company, General Motors, Rivian, and a number of EV charging companies recently announced plans to adopt the NACS connector through adaptors or future product offerings.

The standardization process is the next step to establish a consensus-based approach for maintaining NACS and validating its ability to meet performance and interoperability criteria. The Joint Office of Energy and Transportation was instrumental in fostering the SAE-Tesla partnership and expediting plans to standardize NACS—an important step in building an interoperable national charging network that will work for all EV drivers.

“Standardizing the NACS connector will provide certainty, expanded choice, reliability and convenience to manufacturers and suppliers and, most of all, increase access to charging for consumers,” said Frank Menchaca, President, Sustainable Mobility Solutions, an innovation arm of SAE’s parent company, Fullsight, which focuses on initiatives that lead to net zero transportation throughout mobility sectors.

The new SAE NACS connector standard will be developed on an expedited timeframe and is one of several key initiatives to strengthen the North American EV charging infrastructure. This includes SAE-ITC’s Public Key Infrastructure (PKI) for cyber-secure charging. In close cooperation with National Labs, SAE also is contributing to reliability design for the national ChargeX consortium.

“Taken together,” said David L. Schutt, CEO, SAE International, “these efforts will contribute substantially to SAE’s commitment to secure, clean and connected transportation, accessible to everyone. We’re delighted to do our part in aligning the excellent efforts of industry with those of government entities like the Joint Office to advance sustainable mobility on a national level.”

License tracking could present problems here.

Back in the 2012 case US v Jones the US Supreme Court unanimously held tracking someone with GPS without a warrant was unconstitutional, a violation of the 4th Amendment provision against unreasonable search and seizure. There are numerous cases at the state level now trying to apply that ruling to other means of tracking by the government. Detroit Police tried to install a license tracking system and it caused a real s**tstorm.

It is also strongly regulated here - we have high personal data protection laws in EU (GDPR). With the roadside cameras, they are not tracking cars with gps, the systems cannot be linked and can only be used for the intended purpose of billing. It has been in use for quite some time and so far no scandals regarding abuse of the data have surfaced... (it may be a matter of time)
It fits in with trajectory speed control checking, where they check your average speed over some section and that average speed cannot exceed the speed limit.

Old system here was vignette sticker like in Austria and other nearby countries. They demolished toll booths which increased throughput since there is no more slowdown.

New system is licence plate recognition. You pay for 10 days, a month or a year from picked date, your licence plate gets entered. You can do it online or at the gas station. There are licence plate recognition stations and patrols.

This is of course different than when you turn on location sharing via Google, Apple or whoever, because you're giving consent and it's not the government.

Of course it also means the real time GPS tracking done on shows like CSI, Criminal Minds, Law & order etc. since Jones was bullhockey. They would need a warrant, and to get that they would have to present probable cause (evidence that a crime was being or had been committed by the suspect). No sticking a GPS tracker on somebody's bumper like a wad of gum in a fishing expedition.

How does that work exactly? It seems like a hassle to me to have to transact at a fuel station every time you want to use a toll section but it may be simpler. License plate recognition seems nice. We considered that in the 90s and then the tech was deemed not be there. Also, how would this work for, say, foreign travelers? You can recognize the plate but how do you enforce recourse?

It is quite a long section of highway, plus you can go to any Orlen fuel station in Poland (it does not have to be on the highway, you can even buy it several days in advance and cancel if you did not use it). I'm not sure if it is already operational, but there should be an online system as well.
Other toll-roads (or sections) have toll-booths, but usually they also have an e-toll gate that works on license plate recognition (with online payment or subscriptions). My ING app also works for some toll-roads, in which case the GPS is used to verify and matched with license plate recognition.

Foreigners should also pay, but I don't know to what extent fines are sent abroad.

New systems don't require toll booths. On section of the S8 in Poland has tolling via license plate recognition. You buy a ticket at a fuel station for a time window and a section you want to drive (or have driven), and just drive on the highway. No need for toll booths, so space is not an issue.
The free alternative here exists, but it is literally hours of detour on local roads - so not really a reasonable alternative.

OT: We returned, had a great time in the US (California and Colorado). So that V70 which is considered a sizeable car here? It is tiny compared to what I drove in the US. Everything is tiny here in fact

Plugging the EV into a "normal" US wall plug would be 120v, which would take days to charge. 240v is for heavier equipment like clothes dryers, an electric hot water heater, or an electric range. Now we are adding EVs to that list.

Faster charging, such as via a 240v->NACS adapter cable, would mean another 240v circuit in the garage connected to the primary meter. The time of use* data on the primary meter showing 15-45 kWh at 2200-0600 would be a dead giveaway that the car was being charged on the wrong meter. From here excrement flows downhill.

* our smart meters include time of use so they can bill a surcharge during the peak use period of 1500-1900 Monday-Friday

Do you have meters that show down to that timescale? Because if it is aggregated to e.g. a month or even a 3 month billing cycle, a higher use is an indicator but not enough to detect it.

Still, quite different systems with in the EU, where we all are only on 240v...

So toll booths, that is the issue. Where toll roads and booths make sense, there really isn't the space with us. Also, I *think* one always has toll-free alternatives like, e.g., in France? They're a nuisance to drive but there are certainly people that chose these to avoid toll. We have no way of providing a free alternative, again due to space. I think our freeways are high-up on the list by density of run-off/run-on ramps for instance.
