After 1723km and 4 weeks of ownership I almost down to 99% according SOH. The daily 0.01-0.02% drop continues every day no matter if I charge to 100% and leave it so for hours (or half a day) or keep it around 80%, whether I only do L2 or I do Chademo. I start to think, that the SOH value in LeafSpy does not have anything to do with real SOH. The AHr is dropping also continuously the Hx is keeping rising. Current values are:
The only thing what gives some idea about degradation are the GIDs. I still can charge the car to 498GIDs, and if I assume (from LeafSpy) that 500 is the max for 40kWh pack, it is 99.6%, and it is quite steady, since I got the car it was always like this. I once managed to charge to 501 GIDs, but I think that was only a mistake reading.
I had to look up you to see if it was you who I replied to earlier.
I still say, who cares? These values will continue to fluctuate and will have some variance. Even the # of gids on a full charge will vary, It's not like the battery has some magic output value that tells the car remaining capacity. They only have +, - and temperature sensors. You should just look at the long term trend. Let's see what it looks like in 2 or 3 years.
I posted my capacity bar loss at http://www.mynissanleaf.com/viewtopic.p ... 15#p511915
from Nov 2017
. Back then, Leaf Spy would only show whole numbers for SOH. That day it was 83%. Skimming thru my trip logs, I've had periods of time after that where SOH became was high as 86% but I was still missing a capacity bar. It never came back.
Looking at the latest entries and going back about a month, my SOH is now typically 83.xx% to 84.xx%.
