The data suggests the gid count was reduced during the summer, but the power from the wall suggests the amount of charge remained fairly constant with just gradual monotonic degradation.edatoakrun said:, from a later capacity test, or as calculated from the range test?
Your charge capacity records still seem to show something may have been limiting your charges last Summer, IMO.
Was there any discussion with Nissan of whether this had occurred, and could also have limited your charge prior to the Phoenix range test?
It sounds like you are describing what we see In "best fit" below, correct?
Could you please elaborate on how those points and the cumulative declining capacity line was derived?

What I still don't understand is why your data does not seem to show any record the seasonal decline in charge capacity as measured by "0 to 80 wall" and " to 100 wall" last winter, that most of us seem to have seem to have observed when watching our own battery capacity.
Is your battery temperature at the time of charging more constant year-round, than would be typical?
If your battery temperature typically was significantly lower during charging over the Winter, than in the fall when you began to record observations, I can't see an easy explanation, other than the BMS, for your "from-the wall" data, which seems to show no seasonal loss of battery capacity due to colder battery temperature during winter charging.
