Uhm. That unit requires 380-440V 3 Phase. Nobody in North America has that available in their home. So I am going with no on anyone else doing this at home.
Most North American homes have max 48kw available for their whole home.

In the EU, almost all homes have 3-phase power by default!

Yes, I am aware. Strictly speaking about North America. Also, most homes in the EU can't support a 63A load on their main breaker since its typically 60A. I am sure at additional cost it can be upgraded, but it still falls in line with.. most homes would not be able to support this sort of charger.

That's likely a gross exaggeration.

No he is 100% correct. It's only Canada and the US that use the outdated standard of providing single/split phase power. Most other countries do not use split phase, but rather get their 230VAC from a single leg of their 3 phase circuit.

EU is not only Findland, Germany, France, etc. EU is also Estonia, Lithuania, Latvia, Bulgaria, Slovenia, Poland, Hungary - countries that carry a legacy of the Soviet regime, and typically aren't as economically agile. That was the basis of my comment.

I am pretty aware considering I was born in Poland. I can tell you with certainty that my grandparents apartment built by the Soviets in the 1940's most definitely has 3 phase power, and all the countries you listed also have 3 phase power including those that are not part of the EU, like Russia, Ukraine, Georgia, etc.

Most newer homes, yes. Most homes in Canada which are a few decades old have 100 amp service, and thus a maximum of 24 kW. That's lots if you're not heating electrically or running a commercial or industrial operation of some sort.

Regardless of the voltage and number of phases, it makes no sense to equip residences with several times as much power capacity as they could ever use, so charging an EV at 40 kW implies either monitoring whole-system current so that the charger can "throttle" down to avoid overload, or shutting off other load circuits while charging.

Since 2018 all new homes in Ontario (Which accounts for over 38% of the population of Canada) have to have a 200A panel.
Same holds true for several other provinces.

hopefully, people won't insist on being able to fast-charge at home between getting home from their commute and going out for the evening, while simultaneously cooking dinner and doing laundry. "Smart" metering systems are rare in most of Canada, but that's likely to change.

You are right.
I can't imagine it being a thing. As range increases the need to fast charge decreases as you typically are not depleting your entire pack every time you go somewhere.
First generation Leaf owners are essentially doing that very thing, and are depleting their packs on almost every significant outing.

I have a S and a 3 in Ontario that share a single 48A Tesla charger that could just as easily be installed in a home with a 100A panel and still run the stove but maybe not the dryer.

Right, but as range incrases (larger batteries) it takes longer to recharge at home. 120-200 kwh Rivian and Hummer EV owners are going to be surprised when the run the battery down to 10% and plug in at home and the ETA is 24+ hours.

Have they actually announced the size of the pack on the Hummer?

I have a 100kWh pack in my model s performance. @ 48A via the Tesla wall charger it takes me just under 8 hours to charge 80% (10% min to 90% max) This is the max it can charge from a AC charger.

so 16 hours for a 200kWh pack assuming the do not include a larger built in AC charger.

There's more than one Tesla onboard charger...literally. You could get master/slave OBC's in a Tesla to double up the 45A (to the battery) "19kW" charger to 38kW...

You can do a lot more than 48A from the wall...

Yes, there are more than one onboard chargers but never a AC 38kW unit.
The max AC onboard charger has been 22kW for the older model S/X and 16.5kW if attached to 3 Phase power for the newer S/X

While the rest are limited to 11kW and some as low as 8kW.

Anything higher than those numbers and you are not using the AC onboard charger and are running a DC fast charge.
