Observed something very strange in my Leaf yesterday! My GF had picked me up from work, after driving about 12 miles, possibly quite quickly. I parked the car up on the driveway, and went to reset the trip counter, noted that there were 5 bars of charge left, and 35 miles range. I then looked at my LeafDD which said 31.05 Ah remaining. Then it changed to 31.06Ah. OK, that's a tiny change I sho.... 31.07Ah. Hmm.
I sat for a couple of minutes just watching. What was actually happening is the reported capacity in Ah was fixed, but the reported SOC% was increasing. It started on 50.something percent and was creeping up. I was thinking "well, the LeafDD is an aftermarket device. It's reading the SOC from the canbus, but maybe the capacity number doesn't update. Still odd for the SOC to increase. Unless a downward calcualtion of capacity is happening, meaning my current actual charge level needs to go up because there's now a smaller battery to represent" and -then- I noticed
36 miles
On the GOM. Well that's mighty weird I think. but, maybe the climate control load changed or.... something. By this point, the LeafDD was reporting just over 33Ah, and eventually I saw 37 miles. Still that doesn't prove anything I....
6 battery bars. It added a bar in front of my eyes. So now the official instrumentation has shown me an increase in charge level -and- an increase in range, so I don't think it's a downdialling of capacity forcing an increase of reported SOC.
The car stopped making changes at just over 33.5Ah, at about 53% SOC.
Has anyone ever seen this before? What exactly does it mean?
