It's even better than that. The by far most expensive part –connecting the power source – has already been done. All you need is build a charger. You don't need fuel deliveries so it's in fact a huge logistics simplification.
...with EV market share at small single digits.
It's easy to imagine from some tech-utopian perspective, but scaling that up isn't straight-forward, and we don't know how the business or subsidization should work, or how much infrastructure needs to be rebuilt. Remember, EVs are far heavier than equivalent ICEs.
I don't think any infrastructure will need to be rebuilt. EVs aren't that heavy. Certainly not as heavy as many vans.
One doesn't belong with the others and hasn't remote mountain stations let alone mountains as the name implies. Did you think of Finland?
As an exercise, try the Tesla Go anywhere tool ( https://www.tesla.com/trips ). Note that this is only using Tesla charging stations which are merely a small part of the whole network. But a very convenient part. You plug in for 25 minutes and do a bathroom or lunch break or go shopping or watch a short movie - typically possible since the stops are at convenient locations for that.
Remember that you never need to think about any of this. You tell the car where to go and it will plan all the required stops for you.
Having used an EV for some time now, I don't want to buy one that charges much faster. Once the charging is complete you quickly have to leave the charging spot, because there are fees. So you don't want to be stuck in a queue at the bathroom or shop.
In any case, new chargers have improved to 250 kW and 350 kW is coming, so charging times can be down to 10-15 minutes if the car supports it. And let's remember that most people only need this for long trips, such as going on vacation. I never charge on a public charger day to day. I have not charged anywhere except at home for many months now.
Source: did that with my family several times.
Also, people go on vacation more or less at the same time, so be prepared to be in a line before you can charge.
With people just having to sit inside, because if they leave they lose their spot in line.
