That sounds a bit hyperbolic. Norway is a long country with multiple climate zones. Average temperature in March in Longyearbyen [1] is 3.4 F. Meanwhile, Embarrass, the coldest city in Minnesota according to Google, averages 8.3 F in January. Cold record in Norway is -60.5F, which is about the same as Minnesota's -60F.

According to folks living in Karasjok, the problem with EVs in extreme temperatures is the 12V starter battery capitulating once you dip below -40F. Petrol cars usually fail to start for the same reason.
