So a friend of mine with a 2013 Leaf (MFG 6/13) just lost his first bar two days ago. He doesn't have a battery app so I took a reading. What I found was kind of strange. I wasn't able to take a reading at 100% so had to extrapolate max GIDS and kWh.
This was taken about a day and a half after the bar loss. The car had been charged to 100% twice since then.
Miles 37100
95 GIDS
7.38 kwh
45.49% SOC
84.53% SOH
83.34% HX
56.01 AHR
71.6 Degrees
If I look at Ahr, there's no way he should have lost a bar. If you look at HX, perhaps, SOH, possibly, but if you extrapolate out the 95 GIDS or 7.38 kWh to a 100% charge, He'd be at 215 GIDS or 16kwh respectively? Which seems way low for only a first bar drop. I feel like he should be somewhere like 235 or 18.8 kWh for having just lost his first capacity bar.
What is stranger is that if you compare his readings to my most recent on my 2015 (MFG 4/14) some of my readings are very close to his, but I'm reporting 267 GIDS at my last full charge. My car is only technically 10 months older based on MFG date and has roughly the same mileage at 36300. My readings are 267 GIDS, 20.69kwh, 97.19% SOC, 85.96 SOH, 86.84 HX, 56.95AHR. So by the SOH, HX, and AHR numbers, I should be about 1.5-2% capacity away from losing a bar, but if you look at my GIDS/Kwh, I'm at least 6% away?
Anyone have any thoughts or insights?
