I used .0785 because that was the best fit for the spreadsheet I use where I track my degradation. It compares GID's reported to AH reported by LeafSpy. I used the nominal battery voltage x the amp hours reported x a constant to calculate GID's. I got the best agreement with observations with 78.5w/GID. YMMV.cwerdna wrote: ↑Thu Jan 02, 2020 10:38 pmThe default in Leaf Spy IIRC is 77.5 watt-hours per gid. Whether or not that's actually correct at all, esp. over the entire range of the battery is ummm...questionable.
See https://mynissanleaf.com/viewtopic.php?p=562501#p562501 and the posts I linked to.
Since I used starting and ending values from LeafSpy, regen would have been rolled in. It's possible that Nissan's dash calculation doesn't consider regeneration which would push it's numbers higher but I have no idea how Nissan calculates it. That's part of the question here.
If you covered 220 miles with 53 KWH then you averaged 4.15m/KWH not 3.9. Even at 4.0m/KWH you would have had only about 3 KWH left. Your dash read low, mine seems to read high. Could be just the difference between a '16 and a '19 model with different size packs. I'm just curious about the accuracy of the gauge.DougWantsALeaf wrote: ↑Fri Jan 03, 2020 9:20 amFor long drives I depend on the dash miles per kWh.
It feels spot in for me when calculating back to what LeafSpy says I have left, if not slightly low. When I was driving back through rain from Iowa city, I ended with 3.9 efficiency for the 220 or so miles. With 58 kW usable I should only have about 226 mile range. I ended with over 5 kW left, which is about 20 miles or 240 total possible. Now with only 1 decimal precision it could be 3.94 or...3.99 depending on how it shows up. At 3.99 we would be pretty right on.
