Losing nearly 3Ah or 5% in two months is pretty extreme for a car which is already 2 years old - it really is more proof that suggests that the Ah / capacity readings are adjusted or normalized for temperature some how.
Coincidentally, the SOC is nearly the same in both pics and the pack voltages are basically the same, too - at least as expected the later pic has a slightly lower SOC% and also has slightly lower cell voltages.
In your 2nd pic, your pack is definitely pretty warm for San Diego, especially for mid-morning (mid-upper 80s) - out of curiosity, how much driving/charging was done before that? My car has been showing temps like in your first pic in the mornings - mid 70s - 5 temp bars. I have seen low 80s a few times after sitting in the sun all day before it cooled off the last week or so.
Edit: Just noting in this thread as well that it appears that the threshold for losing a bar is right around 55.25 Ah...
I'm going to go out on a limb and estimate that you will lose bars at these Ah readings:
11: 55.25
10: 52.00
9: 48.75
8: 45.50
7: 42.25
6: 39.00
thanks for the estimates drees. i'll post when I lose the first bar. when i do a run at 70+ mph on the freeway i'll get into the low 80 degree range despite ambient being in the 60s. i typically get out of the garage in the mid 70 degrees after a charge to 80% in the morning these days.
