Honestly we don’t need that charging speed right now at least in the US. We need more L2 chargers where people leave their cars idle where charge time is irrelevant. To satisfying the “but sometimes people” what would be vastly improve the EV road tripping experience isn’t changing speed but quality and quality. No one should pull up to a DC charger and have to wait in line because two of the four chargers are off line and the other two are providing derated power.
I doubt these will go anywhere near houses or even shops, they’re more for highway travel. I maintain that for the overwhelming majority of users in 230V countries a standard wall outlet is adequate.
In the UK, that means 13A × 230V ≈ 3kW. EVs typically do 4km per kWh, so every hour of charging gives you 4km × 3kWh = 12km. Most people’s cars are idle for over 22h a day, but let’s say they only charge overnight for 8 hours when electricity is cheap; that’s 8 × 12km = 96km range.
I’d guess that the UK, kind of line the rest of Europe, has a three phase system which usually allows up to 11 kW (16A x 230V x 3). Which is more than enough for charging at home.
The Dutch powergrid is straining at capacity, and being one of the most densely populated countries in the world, that’s takes a lot of time and money to fix.
