So should I bring my Leaf to Arcadia and you'll troubleshoot "my problem"? You do have a Nissan Consult III
diagnostic tool, right? We would possibly need an oscilloscope. So I'll bring my 50MHz sampling scope to
check the microcontroller chip in the BMS. Maybe we could read the BMS' micro-code and then disassemble
it to find "my problem". Erratic power-ons to ECUs have known to be problematic for automotive electronics
corrupting the flash memory in an ECU's microcontroller. If that's the case, your Consult III should be able to
re-flash it. But maybe not, since Nissan will probably require our logging-on to their website to download the
re-flash data file and authorize it. Well, let's give it a try, OK?
Is your sarcastic posting an admission that your car isn't normal? You've babied it and it's degradation is only minimally better than my 2013 S when I turned it in at 46k miles, ~78% SOH (showed 1 bar lost).

I think you mean you have 12 bars at 51k miles.

What *is* your Ahrs ?
From my corrected typo post up thread:
How do you explain my 24kWh Leaf at 54k, 12 bars, 51 Ahrs.
Sorry for the confusion. An additional data point; SOH = 75%.
Other data:

1. Max battery temp <= 38 deg C
2. Max battery discharge point => 15 Ahrs
3. Typical QC < 15 minutes
4. Typical number of QCs per week ~ 3
5. Always L2 to 100% & 5x per week
6. Typical freeway speed 50 - 55 MPH, resulting in a typical battery power
of 15 - 20kW (level terrain)
7. Average miles per kWh - 5.1 (expected range @ 30-40 MPH - 2 miles/Ahrs)
8. Typical max range before QC needed - 60-65 miles (assumes min Ahrs>15)
Did I miss your report of an Ahr rating from LeafSpy on a full charge ?
Your (8) is not helpful. If you provide a start Ahr, end Ahr, and Odometer change for a 50+ mile trip it would make some sense. Collect a few so we can gauge precision of the test or combine them for an estimate.
Have a reading problem?

65 miles / (51 - 15 Ahrs) = 1.7 miles/Ahrs, or typically 60 miles / (51 - 21 Ahrs) = 2 miles/Ahrs

No reading problem, you said "Sorry for the confusion."

Your car would be exceptional (and malfunctioning) if it currently displays 12 bars capacity at 51 Ahrs when fully charged, or you are lying.
I'll wait for a non-manipulated photo of your display before deciding which is correct.

After owning a Leaf for 7 months, you're now an expert evaluating other Leaf's data? What a joke!
Initially you didn't even know what an Ahr was.

Expert enough ... maybe ... to evaluate your photo of your car meter for photoshopping.
Expert enough to count the battery capacity bars on the photo.

Most definitely not expert or anything remotely resembling expert when it comes to electronics.
I'm pretty sure you know a lot more about electronics than I do, but the current question is whether you are truthful in your reporting

The last few pages of this thread have been about how this statement didn't make sense. It turns out the problem is you are at 11 bars, not 12.
