After doing my regular commute today, which I logged entirely in Leaf Spy Pro, on the 'battery cells' page I was given a note that I had 4 weak cells. The delta was 40 mV. Dash SOC 15%, 44 GIDs and 3.3 kWh remaining. http://kootenayevfamily.ca/img_1350/
This surprised me, as I haven't seen this message before (although I've only had the app for a few months, and have only fully logged several trips).
A few hours later, my wife took the car to the grocery store, and arrived home with 8 GIDs - I ran it down to turtle at 6 GIDs, then took a screenshot of the 'battery cells' page again - no weak cells anymore, despite the delta of 374 mV! http://kootenayevfamily.ca/img_1357/
Running the numbers through the formula up thread shows that my minimum exceeded the calculated value, so I guess that's why they didn't show up?
Anyways, my SOH has generally been quite high for how old my car is, the mileage and the reasonably hot summers, so I'm not really complaining, and will keep a watch out for more of the same. I can't help wonder though if it is somehow related to the other item I've noticed with 'clunking' sounds from my battery pack and odds 'burning' smells!
