Today, is it not 400/230 V, at least in Europe?
The world wide standard is 440/220V, depending on whether it is single or double phase connection.
Car chargers go on the 240 volt connection in the USA too 
The mains supply to my rural property is 11kVA and the transformer feeds 3 phase 400V to the shed and the shed switchboard feeds single phase 220 to the two houses.
It is a pretty common setup for farm properties, dairy sheds use large refrigeration plants to cool the milk quickly.
One reason for the large savings in Norway is that 98% of the power generation in Norway are by renewable sources (hydro and wind).
The 2% non-renewable is at Svalbard (coal) and offshore installations (natural gas)
PS> Another factor is low power costs of home charging and that the fast charging facilities are widely available,
The fact that ALL car brands has same connection and ALL charging standards are common also help.
(Even Tesla is forced to comply)
The US equivalent:
NZ has 85% renewable but the Greens donât like geothermal or hydropower and fossil fuel exploration has been shut down. Scaling up now depends on solar and wind. Our largest supplier of solar power to residential applications has just gone into receivership.
So far the most practical vehicle is the plug in hybrid. The BYD Sealion 6 SUV made in China does 90 kilometres under pure electric and 1200 kilometres with a full tank of gas. If the power goes out your still mobile and it can supply 240 volts 10 amps to an appliance. It averages 1.1 litres per 100 kilometres over long distance.

Looks impressive:
But does it tow a boat or camper?
The AWD version 1300kg for a braked trailer 750kg for unbraked so a pretty small boat or camper.
Not bad. Unfortunately if you stray from the rural area where I live the car parks donât have enough space for you to open the doors of An F150. Ford are building a Ranger (a compact Ute) that is a plugin hybrid built in South Africa. 3500kg tow rating,70 km electric and it can provide 240 volt externally.
EVâs will clean up city pollution but if you live in high rise how to charge?
double phase??
Most of the world is 220-240 single and that goes with 380-415 3 phase 50 hz
The 440 -220 ( split phase ) 60hz is weird power from one country and some ships.
OK, I stand corrected. Obviously more used to ships/rigs. Iâm not an Electrician.
From this it is obviously a lot more complicated than that âone country and some shipsâ being different from the rest:
PS> When I was travelling a lot I carried a travellerâs multi-plug adapters
for various outlet types. (Still have one):
As well as a converter from 110/120V to 220/240V, v.v.:
Didnât need to worry about Hz, nor about higher voltage, since I only carried my phone and laptop.

Switch mode power supplies can convert anything to anything
Semantics issue here.
In North America standard residential power is 240 volts SINGLE PHASE. The transformer out in the yard or on the pole has a center tap, so you get three wires with the center one called the neutral. Hot to hot is 240 volts, hot to neutral is 120 volts. A house will have a lot of 120 volt outlets and a few 240 volt outlets for heavy demand things like a stove or dryer.
Many people, electricians sometimes included, call the legs PHASES when they are not really, it can be confusing. The accurate term is SPLIT PHASE.
Industrial power is 3-phase at various voltages, big motors and loads are three-phase.

There was 120 volt DC power in New York for some theaters that needed it for much longer than I ever thought, it is gone now I think.
Info for power geeks:
The last of the Consolidated Edison (the New York city electrical utility) DC power lines was severed and replaced in 2007 â over a century after alternating current became the prevailing electrical technology. Moreover, there are still a number of DC power systems in place in New York â the NYC Subwayâs third-rail power supply chief among them.
Con-Ed didnât begin the project to finally deprecate all DC consumer power transmission until 1998, and it took nine years to finally convert all the DC lines to AC. In many cases, those DC customers still have DC lighting and power inside their homes and shops, but Con-Ed converts the AC line-power to DC with an on-premise rectifier.

single phase 240 in USA???
Yes, pretty much every house has it. It would take forever and a day to charge a car off a 120 volt outlet!

so you have one wire with 240v to ground in itâŚI dont think so
You 220v devices like stove dryer welder etc have 4 pin plugs as split phase has 2 x 110v wires phased 180 degrees apart.
Do you live in the USA?

If you had single phase 240 you could plug EU devices in right!!
But you dont you have 110v single phase
