Not to quibble semantics with TickTock, but I doubt his LEAF "gained back" capacity. I think it's far more likely that his LEAFs battery management, allowed him to charge to a higher percentage of the Battery's existing capacity, once climate conditions permitted.
And this would imply that many who have lost a bar, may not have lost a full 15% of battery capacity, but that their own LEAFs may be similarly restricting charge levels, under present hot conditions, to prevent rapid capacity loss.
That would be another classical example of how ignorance creates fear....
I am curious though how the bars would come back???
Thermodynamic processes of the kind that degrade the battery are usually irreversible?
Reply by edatoakrun: There is no evidence that the bars accurately (and only) represent "Thermodynamic processes of the kind that degrade the battery".
I have no idea of whether the seasonal increase in capacity TickTock observed last year by gid counts, presumably due to the BMS allowing charging to a greater % of total battery capacity, will result in the twelfth bar "reappearing" on any LEAF dashes in the future.
If your theory holds (lower capacity bars= temporary temperature dependent battery protection) one would wonder why
a) Nissan would have stated that right away in response to the loss...this would have been such a graceful explanation
Reply by edatoakrun: Nissan has had a policy of NOT making any detailed comments on battery capacity from Day 1 of the LEAF launch.
Whatever the Legal or PR reasoning behind this policy, I doubt it will change much in the immediate future.
b) Last year in Phoenix (when it was hot too) no bars where lost?
Reply by edatoakrun: The battery bars may display available battery capacity, both as reduced permanently by degradation, and also as temporarily restricted by the BMS. Presumably, even TickTocks LEAF, which had the lowest total documented battery capacity, had enough battery capacity remaining, to keep the 12th bar on display.
Since neither a) nor b) have been confirmed, it seems unlikely that this is the case and bars come back from the dead...
Reply by edatoakrun: You are correct, neither have been confirmed, and Ticktock's gid reports have not yet been corroborated by others with gid counters. I hope more LEAF/gid meter owners will post their observations. I really don't think you should be too concerned about whether your 12th bar comes back or not, as long as your battery capacity has not been permanently degraded by between 15% and 21%, which is what many seem to believe 11 bars definitively shows.
