We're located in San Diego a couple blocks from the water so climates are reasonably moderate and car is generally driven with a few miles of the coast where things are cooler. Car is rarely charged to 100% unless we are going to be driving it immed. LOTS of QC. It is my opinion that charging to 100% is more likely the culprit and not QC.
You need to pull the leaf spy stats, because all other info is insufficient in detail to make any kind of conclusion.
I'm also SoCal, and my leaf spy stats are in my signature. I haven't lost any bars either, but the leaf spy stats tell a different story.
Since you have been helpful in providing the forum data about your 30kWh Leaf and since you indicated your frequent use of QCs,
it would be helpful to supplement the 40kWh data Dave provided on his 2018 Leaf:
http://mynissanleaf.com/viewtopic.php?f ... 90#p523924
If those with a 30kWh Leaf who QC could complement the helpful data provided here; viewtopic.php?f=27&t=25519&start=90#p523924
by Dave's data gathering on his 2018 40kWh Leaf, i.e. internal battery resistance data, by performing the same type of test (about 10-15
seconds at the start of a QC), that would result in having battery data on all the Leaf batteries, 24/30/40 kWhs. If that test results in the
battery resistance of the 30 kWh battery being about the same as both the 24 & 40 kWh batteries ( ~ 50 - 60 mohms), then it could be
implied that the additional prolonged 30 kWh battery heat over time (like the 40 kWh) results from a higher battery thermal resistance
(lower heat conductance) to ambient, e.g. resulting from a higher density battery volume. This would help explain the higher battery
degradation some 30kWh Leaf owners have experienced over the 24 kWh battery, and what some 40 kWh Leaf owners will probably
have to confront over time, which in hindsight necessitated TMS more so as the battery density increased over the 24 kWh battery.
Thanks for your help.
