Please don't generalize "Europe" when you aren't sure. (Also goes for the GP.)

I have three-phase power in an 80m² apartment, as that's standard in Denmark.

I never saw three-phase power in a house or flat in Britain, but part of the terrible plumbing is 7-9kW electric showers. (Cheaper to install than a shower connected to hot water, landlord doesn't care about the price to run it.)

Now now kids, play nicely. ;-)

I think the underlying question we should really be asking here is not willy-waving over whether you have a three-phase supply or not, but rather how large your main fuse is (there's a euphemism for you !).

I'm not familiar with Denmark, but I suspect even your fancy 80m² apartment with its three-phase supply will still only have a (relatively) tiny main fuse.

TL;DR you're still not going to have a supercharger at home any time soon.


40A on each phase, so 120A total — at least as I understand it [1]. I think that's plenty to charge a car, but good luck parking on the 4th floor. The oven and hob use all three phases. I think tumble driers used to, but they're now so efficient in the EU it's no longer worthwhile.

Several ordinary 3-phase sockets have been installed by parking spaces in the basement, and are rented by residents with EVs.

Yep, and even if you have 3 phases and a large main fuse, the issue remains when you sum all the power needed on a same street in a city.

And I apologize if I seemed to improperly generalize.


I hope I am wrong on that, but this is exactly one of the two largely unaddressed problems for a complete change to an EV fleet in countries like Germany. 1) Do you have enough power delivery available, especially with the push to electric heat-pump based heating. That seems to be a serious problem, I heard from some people that they are not allowed to connect their heat-pumps, even in newly constructed areas! Solvable, with political will, but I don't see the will. 2) Where will people charge who park on the streets. It seems there are technical solutions (electrified curbstones), but again, political will to change much infrastructure is required.

true, but a three phase CCS will do 22kw. the EU has the advantage that 240v needs half the current to get the same power as the US


Homes in most of the US get 3-phase 240v (120 0 -120) at the panel and it's split into 120v for most of the outlets. Some outlets are 240v (oven, dryer).

So it's straightforward to get a 240V charger installed.


Three phase in Europe (and most of the world) means 220V @ 0°, 220V @ 120°, 220V @ 240°, 0V (neutral).

There is 220V between any phase and neutral, and 400V between any pair of phases. I'm not am electrical engineer, but I think the car charger would be using 400V in this case.

If you're ever in a datacentre or factory in Europe (including the UK), you will probably see fist-sized red plugs and sockets to provide about 60A at 220/400V.


No. US homes get split-phase power which is two phases (not three) 180 degrees apart.

3-phase power is three phases 120 degrees apart, and it's extremely rare in single-family homes in the US.
