- s5300 5y agoI’m pulling this out of really old knowledge I’ve not looked over in years so may be incorrect… While you are right about “not well”, the other option can often be “not at all” The batteries used in most EV’s should always work to some degree, with regards to temperatures experienced on Earth - the batteries & other systems in most ICE can be completely crippled/not work at all under certain temps faced on Earth Now, you can specifically go out of your way to ruggedize all systems in your ICE so it works to a much better degree than the EV, but the average person is definitely not doing that.
- kube-system 5y agoThe saving grace with ICE is that they are so inefficient that they literally are mostly heat generators that also produce some mechanical force as a significant byproduct. They might not like starting in the cold, but once they're started, they're fine.
- beerandt 5y agoThere's similar efficiency losses for EVs, but (besides battery efficiency or thermal penalties) they're just further upstream.
- crooked-v 5y agoA heat pump system (such as in a Tesla Model Y or a Kia Niro) is significantly more efficient than a plain electric heater, though I haven't seen any hard numbers for cars with that equipment in winter weather.
- dont__panic 5y agoDoesn't Tesla recommend that users use the heat as little as possible, and use the seat warmers instead, to conserve battery? Or has that changed in more recent models?
