="turbo2ltr"]You are confusing two different phenomena...
No, I'm not confusing them. But I am questioning as to whether the "break in" you observed, is anything other than the BMS at work.
="turbo2ltr"... I believe TickTock's data to be correct and show higher GID at 100% charge with cooler weather. I cannot say if it's the BMS limiting it, or a factor of the chemistry. Maybe someone else knows...
Did you, or other Hot-climate owners observe the same sort of gid results as TickTock, over the same time period?
="turbo2ltr" ...The break in I observed, as have others, is a one time deal when the battery is new. When I first got the car, I would only get up to the 260s. I later observed, I would regularly hit 280. The weather is cool between feb and march and does not change much, unlike between may and June which summer really hits...
So, let's assume, for the moment, that Nissan may have had the foresight to have designed the BMS operation to preserve as much battery capacity as possible over time, consistent with high ambient temperatures, and passive thermal management.
If high states of charge further accelerate battery degradation, in high temperature conditions, the BMS would probably be designed to limit charge levels and gid counts, and would produce gid count results such as those TickTock (as also determined by the underlying trend of capacity loss) has reported.
It is also possible, that LEAF initial charge levels would have also been limited to a relatively low level, such as the 260-something gid level range you initially observed, but allowed to increase over time, to the maximum "safe" level consistent with ambient temperatures.
Do all (low mile) LEAFs show 260-something gids, at delivery??
AFAIK, you are the only one who has gid data from a winter 2011 delivery, but those with winter 2012 deliveries, who recorded initial gid readings, might have similar results, showing a gid increase under cool or cold weather operation.
IF that is what your (and others) gid records show-PLEASE POST!
Did mid-summer 2011 and 2012 delivery hot climate LEAFs, experience the same sort of gid increase, from the 260-something to 280 range, during the initial post-delivery period, as your LEAF did? If so, the 2011s could not have experienced the (winter) seasonal gid increases, that TickTock has reported...correct?
