I purchased a 40 kWh SV on 4/30. The car was built in February 2019. I've put about 700 miles on it since 4/30, and I just did my first Leaf Spy reading on 5/15. I have a screen shot of the reading, but I'm not sure how to post it. Anyway, here are the most relevant stats:
AHr: 114.9
SOH: 99.35%
Hx: 101.31%
GIDS: 196
SOC: 38.8% (the dash SOC says 30%)
kWh Remain: 15.2
1 QC, 37 L1/L2 (this QC must have been done by the dealership because I've never done one. And I've also only L2 charged it 16 times, and L1 charged 0 times, so the dealership must have L1 or L2 charged it the other 21 times. Kind of a lot of charging events for a car that only had 7 miles on it when I bought it).
A few questions:
1. That SOC reading - is that of the usable or the nominal capacity? 15.2 kWh remaining/.388% SOC = 39.175 kWh of actual capacity. So is that what I have? If SOH is actual capacity/40, then my SOH should really be 97.9%. If SOH is actual capacity/38.5 (the alleged true usable capacity of the 40 kWH Leaf), then my SOH would really be 101.75%. On the other hand, if my car currently has 39.175 kWh of capacity, and it has an SOH of 99.35%, then it should have started with 39.43 kWh. So I'm obviously missing something about the math here...
2. The discrepancy between that SOC reading and the Leaf's dash SOC is 8.8%. This must be the roughly 10% that the Leaf BMS software hides from you. But that 8.8% hidden amount is of what original number? 40 kWh? 38.5 kWh? This is another way of asking: how many kWh does Leaf Spy say I have, and how many kWh does Nissan say I have?
