Wow, that is the most balanced pack I've ever seen!
What are you charging/driving habits?
I don't have a set routine, but a typical day would be 40 miles of non-aggressive driving over hilly terrain. 2/3 highway, but I normally end up driving under the speed limit due to congestion or simply to save energy. The LEAF's info panel is telling me 6.9km/kWh, but I've never tested its accuracy.
Most commonly, I trickle charge at home to 80%, disconnecting and storing the EVSE as soon as the charge is complete. I sometimes use public L2s. There are no L3s in the area.
Over the last two months: 17 charges to 80%, 14 to 100%. Several other partial charges.
After you drive a down to half tank or lower, do any
of the cell-shunts turn On (usually red)?
I haven't been under a half recently, but from 55% to 50% SOC this evening there were typically 4-6 lines in red. These three shots were taken in quick succession when I was in park at 50.4% SOC.
