Re: Ubiquitous AC destination charging is the way to enable EVs.
That's right in the grand scheme of the whole grid. The problem is that you're shifting 10GW of load from industrial sites with plentiful transmission capacity to thousands of residential sites with transformers and distribution system designed with 2kW-per-household calculations.
In my housing estate we have a substation and I am told that each phase has a 400A fuse.
At 32A single phase draw, it would only take about 13 cars charging to overload that fuse. For the 3 phases let's say the whole housing state of 100+ houses would only manage 40 cars charging simultaneously. Some of these 100+ houses will more than likely have more than one car.
I am glad that I managed to get my EVSEs and batteries installed early, as the DNO is going to start looking very closely at capacity calculations. Between charging cars, batteries and heating water with off-peak energy I am already hitting the 100A limit on my supply for 5 hours every night (in the winter. Summer is a different story)
There will definitely need to be some sort of upgrade done closer to "the edge" of the electrical network once home energy supply for mobility, heating and cooking becomes exclusively (or nearly exclusively) electric.
