There's two main challenges for EVs in cold weather that cause extra use of energy vs warm weather; warming up the battery pack and warming up the cabin. ICE vehicles also run less efficiently when the engine is cold, so this part is roughly analogous even if there is more extra energy required to heat the battery pack. The main difference is that once the engine is warm, ICE vehicles can then heat the cabin "for free" using waste heat because an ICE is so incredibly inefficient. This waste heat is useless when it is warm but a nice bonus when it is cold. EVs must expressly spend energy to create warmth for the cabin. But this is also why most EV owners know to schedule your vehicle to warm up while it is still plugged in before you depart. One advantage is that you can do this in a closed garage with an EV and not worry about fumes. Cold weather reduces range on all vehicles, it's just more noticeable on EVs due to having less excess range and the aforementioned heating concerns. But I drove a 2014 Leaf for 8 years here in Michigan, without issue. That's a low range vehicle in a very cold climate. It's totally fine.
