I don't care about the percentages in Leaf Spy. What's the denominator?
IIRC, LBW sounds at about 49 gid and VLBW at about 24 gid on 24 kWh Leafs.
The Low Battery warning does come at higher and higher percentages as the battery loses capacity, so a pack nearing 9 bars might show it at about 30%. I would define ~9 bars as somewhere between "substantially degraded" and "severely degraded." How many miles of remaining range the Guess 'O Meter gives depends on several variables, so while it might be consistent for you, it doesn't make for an apples to apples comparison with other Leafs.Silverfish wrote:In the two months I've had the car, I always get a low battery warning at 16-17 miles on the guess-o-meter, which registers as between 29% and 32% in LeafSpy.

More like 18-20%.
How would I know if I had a severely degraded battery? The range is pretty consistent at about 70-75 miles on the GoM at 100% charge, and 55-60 miles at 80% charge, depending on how much freeway driving I've been doing. On 100% charge, I can generally drive 50-55 miles before hitting the low battery warning. On an 80% charge, it's about 30-35.
It's a 2013 SV with about 53,700 miles and 11 bars. SOH is hovering between 76% and 77%, so I'm surprised it's not yet at 10 bars. Do all those numbers not add up right? Maybe there's a way to reset the % at which the LBW sounds, and the previous owner did? I'd be happy to drive it down to 20%, just been nervous because of the warning.
Thanks.

I don't know the numbers that the Leaf or LeafSpy uses to arrive at its percentages, which is why I said I didn't know which denominator you meant. All I see are the numbers in the LeafSpy display pages; most of it is Greek to me. Honestly I'm not sure what use the GID value is either, or how it's used in calculating any of the percentages. I was just providing the data I saw, hoping that that info contained the answer to your question.cwerdna wrote:I don't mean to insult your intelligence but let's take a step back:Silverfish wrote:Thanks, folks.

numerator / denominator = some result that you can convert to a % if you multiply by 100
49 / 100 = 0.49 = 49%
If see SOC % of 28.9% and in an earlier post, you said "which registers as between 29% and 32% in LeafSpy", what is the numerator and what is the denominator to arrive at this? Of what use is this %?
You said "GIDs: 47 (there's also a 16.7% value that might correlate with GIDs)". Why would I care about 16.7%? What's the numerator and denominator here? Do you see why I don't care? I'd rather just look at the actual gid value.
We already have at least 3 percentages that vary with the state of the charge of the battery: SOC % in Leaf Spy, gid % in Leaf Spy and the dash display's % SoC (which was developed by Nissan independently of Leaf Spy). I only pay attention to the dash display's % SoC and raw gid number. The other two percentages I don't care about.
