I recently did the math on this in another thread comparing BEVs to ICE on range. It details the absolute worst case for driving range that I could find with zero gas or charging infrastructure in between. The BEV can actually do it better (in that it gets you closer to the goal under the most stressed conditions) with no further advancements in battery tech.

With only one charging point halfway on this trip, many BEVs would make it fine. Two charging points at a third of the distance each would open up the list very nicely. It looks like there are already high voltage lines near this very route (guessing a little from a map of Canadian lines), so the infrastructure is already most of the way there.

Speaking more generally, outside of this worst case scenario, all we need is more charging infrastructure. A 250-400mi EV would otherwise work fine for the majority of people with little to no new battery tech required. We should take advancements we can get, anyway, but it's not a hard requirement anymore for the average driver.

Original post of mine copied below:

Let’s take the absolute worst case I could find for North America: in Quebec between Matagami and Radisson there is a 620km (390mi) distance between gas stations. This exceeds the range of many ICE cars, but let’s continue. It gets real cold up there, and there’s a few days out of the year where it’s well below 0F. To account for the cold, let’s increase that distance by 40% to get to about 550mi.

There is one EV on the market right now with a 516mi range, the Lucid Air. So it can’t quite make it under the absolute worst case conditions that, even up there, will only happen for portions of the year. Many ICE cars would also fail to make it.

This problem is completely overblown. The 1,994 combined population of those two Canadian towns will have to wait. Literally everyone else in North America will be fine if we just get our charging infrastructure better.

Oh, and ICE cars lose gas mileage in cold weather as well. 15% lower at only 20F. So ICE cars that could barely make that trip under warmer conditions probably couldn’t under the extreme cold of this exceptional situation.
