Range has been shown to be a major issue at low temperatures. That's because not only do batteries function less effectively, the battery also has to keep the vehicle warm. A battery is a chemical reaction, and all chemical reactions become slower as the temperature decreases. No problem for an ICE, it is using the waste heat of the engine.
Conversely, an ICE operates more efficiently in cold weather. Cooler air is more dense, and hence has more oxygen. Ever noticed many international flights are at night, when it is cooler?
An ICE can operate quite happily at -50C. I doubt an EV would have any useful range at that temperature.
