It is not recovery you are seeing with improved numbers. Its better top end pack balancing
What does this mean ?
I look at my pack in LeafSpy and see a maximum delta of 0 - 15 mv between modules. That is not enough to explain any significant Ahr differences.
On a related note, how are the Ahr and kWh rating calculated ?
There is some basic physics here I don't understand where the LEAF is concerned since I usually think of a battery capacity being determined during a controlled voltage charging cycle but that cannot be the method in a LEAF.
First off we need to understand that the #1 parameter is poor Nissan instrumentation that gives us these wild fluctuations.
The other thing we need to understand is EVERYTHING we do is a trade off. There is no action that does not have consequences.
The other thing is that there is HUGE disparity from one car to another INCLUDING one in similar areas. It is this we need to understand. So the conjecture of this and that mattering or not mattering is only that. Because no matter what one person says is the cause of their degradation, we have another who is doing the same thing and they are fine.
So what is the key differences here? Is it weather, Driving style, time on the lot, charging patterns? Or is it simply the newer the pack, the better?
I am betting its a combination of all of that. I have a leased 2016 S 30 build date 10/16 picked up 11/11/16. Time on lot probably as close to zero as you can get. Right now I am in the process of experimenting with the car centering on "heat abuse" I hope to be able to see some results within the next 2 months (which means signs of degradation) that likely won't clear up a lot but will be another step towards having more insight.
as far as how important is top end pack balancing? Its vital, its ALL vital. Why would Nissan go thru the motions of creating the SW that takes up to an hour to run at the end of every charging cycle if it meant nothing?
