Don't all those red bars represent cells out of balance? Also, the accessory battery voltage is critically low at 11.92 volts. Charge it immediately, with an external 12 volt charger! It should be no lower than 12.5 volts.
Your numbers look very similar to mine. (MFG date 9/2014, purchase date 10/2015.) My SOH has been bouncing around between 90 and 94 for the most part since I started measuring it at 800 miles, and at 3000 miles it hasn't really changed that pattern.apacheguy said:LeafSpy screens. I'm a bit concerned about the 91% SOH with less than 500 miles. Anyone care to shed light?

Edit: Upon further reading, it appears that some 2013s showed mid 260s when new, but 2015s seem to show 280-295 gids. This is what I was expecting to see. And more like 22.5 kWh remaining, not 20.8. See for instance:

tkdbrusco said:There are a bit low, but I'm not sure if you established any of the following prior?
1. How long the car sat on the lot before you bought it and when it was manufactured? You could have a car that has 500 miles, but a battery that is over a year old and has sat through a summer on the car lot. This makes a difference.
2. I think a lot of 2015 cars see a drop in max capacity during the winter.
3. How you charge the car can often impact the max reading
I wouldn't freak out to much at this point. I would wait to see how it reacts in April or may when it warms up.
To put your mind at ease, my 2015 car was 292 when new, dropped to 285 (approx) after a few thousand miles, when winter hit last year, with about 8K miles it was averaging 270-275, then during summer of 2015 with about 16K miles, it was back up to 280-288, and now that we are in another winter, with about 21K miles, the car has been between 263-271. My point is that even last year with minimal miles on my car it was tracking low 270s, but it came back up. Your SOH is at 91%, I see no reason why your pack won't be back into the 280s when the weather warms up.
Here are my most recent stats. 21,750mi
270 GIDS
20.92 kwh
97.05 SOC
86.75 SOH
87.93 HX
57.48 Ahr

I've been doing primarily L1 charging and relatively light driving (Light enough that I can get away with L1 charging most of the time, and even then only a few times a week), and from what I have seen I suspect that may be artificially lowering the reading. Whether it is the L1 primary charging or the light driving I don't know. However one day I had done a bunch of driving over the weekend, then a day or two later did a trip that required charging at the destination, which I was able to do L2 to full (But not fully balanced), then I charged it once I was at home (L1), and the SOH popped up briefly to 97% (my highest reading) before settling back down to the 90-94 range a few charges later.
apacheguy said:Well, I always L2 charge and I have let the charge completely finish on several occasions so my pack ought to be fully balanced. Not sure why so many cell strings were highlighted in LeafSpy. I also do not baby my pack. I drive over 60 miles on some days and therefore my pack has cycled 100->5% routinely.
May I ask how many kWh are displayed on a full charge?
drees said:IMO 24kWh from the wall at 208/240V on a '13+ LEAF is completely normal for a couple reasons.
1. The 13+ is slightly more efficient than the '11-12 Tony used in your reference.
2. There is a decent amount of variability in energy used to charge from the wall so you'd need to repeat the test a couple times at least to be reasonably sure the LBC didn't either hit turtle early or cut off charging early because of cell imbalance.
apacheguy said:OP here. Just a quick update. Things are not looking better.
263 gids
55.9 Ahr
SOH 90%
Hx 84.7% (what does that mean?)
