Here's the benefit of a mild climate.
Great example of what can be done but we have people in his very same neighborhood that regularly get "Phoenix level degradation"
so there is MUCH more at play here than climate.
The overwhelming variable is battery temperature -- both average and high*time
Climate is #1 when discussing battery temperature, but usage plays a part, DCFC can be a big player, and ill-advised garaging is my favorite sleeper issue to harp on.
Anecdote:
LeafSpy reported 20F two days ago and last night was expected down to ~ 10F so I decided to drive the car yesterday to bring temp bars up to 4 to have some heat loss reserve and to be able to charge at 6 kW without concern about battery plating. Our 10 mile errand was not enough to move the temp reading from 3 bars, but another 10 miles did the trick. This morning the pack is 3 bars, OAT should reach mid-30s F in the afternoon, and tomorrow average OAT is around 32F so no worries.
The cold anecdote seems out of place in a thread about heat related degradation -- and it mostly is -- but I mention it here to say that every climate has bad LEAF days of one sort or another and owners who want to extend battery range have to mitigate those bad days.
