My '22 Leaf SV+ owner's manual (who reads those?!?) says to keep a Leaf plugged in if gets below around 0F outside or so. Mine is the 62 kWH battery, and instructions for the 40 kWH batteries are similar.
Bottom line: Below 0F, plug it in so it can warm itself.
I'm simplifying a little what the algorithms actually do in response to very cold temperatures. Saying "Just plug the thing in if you see or expect Below 0F temperatures outside" ..., is a good rule of thumb. Arctic Blast this week for a lot of the country!
One interesting difference (anybody know why?) is that the 40 kWH battery does not need to be plugged in while below zero, if SOC is at least 15%, while the 62kWH battery will not operate it's battery warmer at all unless it's plugged in, regardless of battery SOC.
Anybody know the technical reasons here? What happens to a battery that hits a bit below zero and freezes? Surely this has happened a lot in the 11 years Leafs (Leaves?) have been running around.
