OK. I don't want to insult anybody, but I am getting a little confused when I read posts from the likes of Ingineer and garygid whom I consider to be well informed, that imply (to me) the following:
1. 100% charge with the timer will not balance the battery cells. - I say this from reading statements about needing to leave the car plugged in for a few hours after reaching 100%. Since the timer will stop at 100%, that means that all charging is stopped with the timer and leaving the car plugged in 3hrs afterwards doesn't do anything. So only a manual (timer override) charge would rebalance the cells.
2. 100% charge isn't the full capacity when it first completes. - I gather this from Ingineer's 11:54pm post http://www.mynissanleaf.com/viewtopic.php?f=30&t=8802&start=530. Reading this tells me that there is a potential 10-15% SoC gained during that additional rebalance period after the charge has first stopped. So again using a timer would means that even if your cells were fairly well balanced, not getting 12bars isn't necessarily a true loss of capacity.
Could it be that the 11bar numbers at 100% that are being reported are really just an issue with the charger firmware not performing rebalances and the display not truly a SoC or actual capacity? Even with a GIDMeter, since the firmware may be stopping the charge before the battery is 'full', the GID reading can be deceptive. It would seem that without a LEAFSCAN we're kind of guessing.
If one is getting the 11bars after a 100% timer charge, there are several reasons that this could be happening (temperature, out of balance cells, etc), and we might be worrying unnecessarily. However if one has 11bars after two or three consecutive manual (not timer) 100% charges where the LEAF was plugged for 3hrs after it reached 100%, then I guess there is reason that people are freaking out...
Please don't flame me, I guess I'm just hoping that there is a simple answer to this issue...
