Some basic question
Ambient is irrelevant
AC Vs DC is irrelevant; the question you are rightly asking about is current (Amps). I've seen my Tesla refuse to charge the pack at all
when it is in the 20s F, but my pack is low Cobalt and as a result low temp intolerant.Tesla is able to heat up the pack before charging; I'm not sure about the LEAF. Does the LEAF BMS manage current in the cold ? I don't know, but if not then it is on you. It is my practice in the winter to charge only soon *after* a drive to avoid these possible issues.
I suggest you do NOT rely on what Nissan says is "OK." That is based on warranty considerations.
The presumed battery damage mechanism goes under the name of 'battery plating' or 'Li plating.'
