Re: Discuss data from the LEAF Battery app, and Comparisons

Mon Aug 21, 2017 8:24 am

I don't know if this is already known, or obvious to others already, but in fiddling with both my own car's numbers, and with 4-bar-loss numbers across 60-odd cars, I've realized that Ahr & Hx readings vary perfectly linearly. (The linearity is different for 2011/2012 vs 2013 cars, though.)

For example here's Ahr vs Hx values at 4th bar loss for every 2011/2012 I could find:

Image

Here's Ahr vs Hx values for my own 2012 car over time:

Image

So for tracking Ahr or Hx for expected 4 bar loss, I'd say: it doesn't matter. They're proportional.
2012 SL from TX, (mfg 8/12), used, dropped to 8 bars at 43.50 Ahr, 40,601 miles. my daily stats =/= my collected data on 4-bar losers

Thanks for posting the graphics. It further corroborates why some consider Ahrs as a key battery parameter.

Hi mxp,

Thanks for posting update. Here are my battery stats seven weeks since replacement:

2013 S mfr date: 02/13
7/13/2017: Ahr:=65.46 Soh=100 Hx=100.12 Odo=54391 Gid=285 Soc=97.6 L1/L2=1159 QC=0 (New 24kWh battery replacement)
9/2/2017: Ahr=65.93 Soh=100 Hx=101.02 Odo=56508 Gid=74 Soc=33.6 L1/L2=1197 QC=0

The car is usually driven 55 miles per day, 5 days per week, and charged from 2am to 6am Monday to Friday. Just to try something new I have been alternating between 100% and 80% charge every two weeks.
