Norway may be farther north than where a lot of Canadians live but it’s not colder. Where I live (Southern Ontario), it gets quite a bit colder than Oslo, despite being one of the warmer areas in Canada apart from the coastal regions.
I've had my EV for 5 years in Minnesota where our weather is worse than you down south. Other than shorter ranges in the really cold days, no problems with the battery. It's been driven and actually parked outside as low as -25F (real temp not a windchill)
Parked for how long though? Overnight or during the day? My belief is that an EV will perform much better in cold climates if you have access to indoor parking overnight, such as a residential garage or underground parking at an apartment complex. If you have to park overnight fully exposed to the outdoors with deep freeze overnight temperatures it’s going to be awfully tough on the battery.
But people are saying these batteries have built in heaters, so that’s pretty cool. I wonder how much power they’d use in that worst case scenario outdoor overnight freeze? Especially if you don’t have access to charging overnight and need to charge during the day at work.
All day ever day when I was working in an office and when it was -27F out, my son didn't listen and when to his hotel without charging first. Even at close to zero, the car ran fine and he got to the charger. However, the battery was so cold soaked that it had to heat the battery for a long time before it could charge.
Actually heat is much harder on the battery than cold. Different manufacturers have their own battery management systems and they aren't equal.
