Nissan Leaf charging problem in colder climates
Nissan does not have a thermal system handling the cold in their cars. Not even on the 2019 models. This is problematic in areas of cold weather when charging them. Charing cold batteries reduces the SEI layer.
Tesla on the other hand has a thermal system, heating pump, glycol between the batteries, warming the batteries when too cold for charging them (making it doable). (Source video below).
About the SEI layer
"The cell’s solid electrolyte interface (SEI) layer formation is a necessary part of the initialization process of the battery during the first charging cycles. The SEI layer protects the electrolyte material from further depletion and protects the charged anode from corrosion (the anode material reacts with the electrolyte material) [36]." - https://www.mdpi.com/1996-1073/12/5/946/pdf

They also dont have any cooling for their batteries, so the batteries get hot when fast-charging..
This is the same for Li-Ion as for LiFeP04.
