Works down to 11% soc (7 mi to turtle). The last fuel bar disappears at 7mi left. If you drive very close to turtle (ie no fuel bars) the minimum cell voltage is the most accurate predictor of remaining range.
The above is only valid for newer Leafs with capacity in 60 ahr range.
I have a 2013 with 66 ahr, BUT with a bad module see http://www.mynissanleaf.com/viewtopic.php?f=30&t=15768
. I've been trying to show my dealer that this module does in fact decrease the range of my leaf because they are saying my range is fine and thus there is nothing wrong with the battery. Yes I know the manual is clear about what constitutes a bad module, but they are insisting that my range is fine and thus no repair is needed.stjohnh
has noted something that perhaps I can point out to them. He said that when the car turtles, it is really the lowest cell voltage that matters. What cell voltage have people measured this should be and what was the average voltage at this point? In my car, I hit turtle when my bad cell pair is 2.70 V and the average voltage is about 3.20. Is the average cell voltage for most people closer to 3.00 at turtle than I'm getting. Or do people get turtle at 2.7 V like I do. That would be something to point out to my shop.
The other thing is that when I am charged up over 50%, the %SOC on Leafspy is about the same as the %GIDs. But these numbers start to deviate below 50% as shown below:
100% charge - 283 GIDs - 97% SOC (Leafspy)
80% charge - 225 GIDs - 79% SOC (Leafspy)
~50% - 140 GIDs - 53% SOC (Leafspy)
LBW - 50 GIDs - 25% SOC (Leafspy)
VLBW - 25 GIDs - 18% SOC (Leafspy)
Turtle - 6 GIDs - 9.7% SOC (LeafSpy)
I think the GIDs that I get at each of these points is pretty normal, but are my %SOCs as measured by LeafSpy high at the low end, and perhaps low at the high end? This would be another indicator that my battery has low capacity.
If I watch my %SOC on LeafSpy, when I'm down to 11%, even with very easy driving, I've only got about 1 mile left to turtle. stjohnh
says that I should have 7 miles left. So here is a loss of about 6 miles range.
I'd really like some supporting data to take to my shop to help my case. Thanks
