Agree on all of the above. I wouldn't worry about the blue vs. red bars (shunting or not).RegGuheert wrote:9 mV of voltage difference is very low, which is very good, so don't worry about that.
The capacity loss is likely not real. Instead, it is more likely that the seller recently reset the Battery Management System (BMS) just before you purchased the vehicle to make it appear that it had more capacity than it actually does. You will have to wait to find out where your capacity actually lies.
I don't know how long it takes. It'll probably take longer to relearn if the car was down many bars to begin with.calverajarda wrote:I mean 4000km is long time to see battery reset.
I've never heard of any method to know who did it. Dealer or whoever had it before can lie/claim ignorance.calverajarda wrote: Its any idea to check if was battery reset done? By dealer?
Those red and blue bars are showing module voltages, NOT capacity loss. Those will go down as the pack and modules discharge and up and it's charged. There should also be voltage sag under load, esp. heavy load (e.g. full throttle).calverajarda wrote: Why are from capacity loss bars in LeafSpy red but balanced?

I have noticed in previous winters that BMS does not change the predicted value of the remaining capacity during the cold of winter. Perhaps it was "holding" the value it had due to cold temperatures until it warmed up a bit.calverajarda wrote:Here in Czech is more colder - not Californian weather.
This car has not changed in any significant way. The main change is in the estimates of the BMS or battery management system. This might have been due to a BMS reset, or might have been due to the estimate changing due to changing driving patterns and conditions.cwerdna wrote:I've never heard of any method to know who did it.

Don't worry about it. Stop stressing over it. Heck, the shunt order (via settings) may not even be right and thus the representation could be wrong.calverajarda wrote: and about red bars (shunts) in LeafSpy....
Any way to go them blue?(
