Very nice data here, my 2018 pack is still sitting at 95.x%SOH, and I'm extremely curios to see what the next incoming 2018 40kWh pack I ordered will sit at. It's really cold here :lol:
GaleHawkins said:My question is what technique do you use to stop the charge at 70%?
I have been going to 100% then driving shortly there after but the last two times I caught it at 90% and stopped the charging. I want to charge to 80% from around 40%.

I set up a daily timer with an end time of 10:30 AM, a start time of 10:00 AM, and "full charge has priority" turned on. With these settings I can plug in the car at any state of charge the night before and it will automatically decide when it needs to start charging to be at 100% by 10:30. By 8:00, when I normally leave, the car is usually right around 80%. On the days I'm not heading out, I simply unplug it at 8:00 and it can sit for the day at a happy 80%. The times may need to be varied a bit based on temperature and depending on the type/amperage of the plug you are using. I use the EVSE that came with the car with the NEMA 14-50 plug on a 40A circuit. I use 15%/hour as a rough estimate if I need to calculate charge times rather than using the timer. Also, I do not have time of use billing so that is one less complication I need to worry about. Happy charging!

LeftieBiker said:I did my (just short of) two year LeafSpy reading a few minutes ago. I'll post the details later, but the Spoiler is: 91.69% SOH. My Leaf seems to have finally stopped the rapid decline in SOH. Either that, or it still thinks it's Winter.

Mine just keeps ticking down. As of this AM I'm at 90.18%. Also today for the first time this year the temp bar went above the middle. Sumner is here.

I know some of you don't think heat impacts the 2018s but as soon as it got hot, my SOH started dropping faster again.
This AM I'm at 90.15%. I'll drop into the 80s before I hit my next major adjustment. No sign of any increase others have had.

Faster than it was during the winter.
During the winter it was dropping about 0.01 every 14 days, plus or minus. Not including the 3 month adjustment.
Now its dropped .01, four times, in a span of two weeks since its started to get hot outside.
In my book that's a lot faster, YMMV.

I plotted your amphour history and the difference in the "Lizard" (replacement) pack in my 2012 is stark ! I'm sure that your Atlanta climate vrs Houston has some influence, however, there is essentially no "repeat" of summer/winter swings is evident in your 40 amphour pack.

ok so that is .08% per month? I think I could live with that.
I have to put myself on record as saying I am not on board with daily readings having any major significance and yeah, this is coming from someone who has recorded stats EVERY day my LEAFs have been driven for a few days short of 7 years.

No its not. You are completely forgetting the 3 month adjustments. My last one was 1.47% just by itself.
I have now had the car for a year. It has lost 7.48% since I bought it.
I don't yet buy into the idea the new batteries are better in heat. This summer should tell me a lot.
I certainly have seen no sign of my SOH adjusting up as others have seen. TBD.
