However, Alberta cold will certainly reduce the range of EVs. And as one who spent 45 years as a Maine forester including 10 in the Allagash-St. John region, I doubt that making EVs that can haul off-road loads (up to 100 tons) at -30F is sensible, as the Diesel used by those rigs is a drop in the overall fossil-fuel bucket.Aha! My experiences in Wisconsin say that used to be a big cause of cars getting rusty. Nowadays cars seem more protected from rust due to salt water, but there are still plenty of rusty cars around here.
Don't know if the road salt hurts an EV battery, though. Anyone?
(Ironically, the huge machines used in open-pit mining use Diesel to generate electricity for the motors at each wheel or track sprocket.)
