This might be a dumb question but has anyone actually done some experiments to verify the range is actually dropping with these digital stats?
My 24kWh Leaf did start to show some noticeable range loss when I got below 85 - 90% SOH. I could tell that because I had a 55 mile round trip commute so I was charging to 100% each night and hitting LBW every day in the winter. Whether or not it was 15% is hard to say because there are so many variables like heat use, ambient temperature, wind, and traffic... but the loss was definitely there. It was like a climate record, I started recording a lot more low end values and a lot fewer high end values in terms of my SOC level when I got home from work.
The 40kWh Leaf has too much range for me to notice any losses. I rarely go above 90% or below 20% SOC now, even if I have to cart my kid to some after school activity, so there is just no way for me to tell what my actual range is. I honestly don't know if I've even hit the LBW on this car yet come to think of it (after 7000 miles of driving).
I suppose if I was really curious I could consistently record temperature and set the cruise control at a fixed value while leaving the cabin heat off. With a very standard work commute, a bunch of data points would beat down the noise and converge on a realistic range. Then I could do the same thing next year, and the next, and the next to establish a trend... honestly I don't care enough to do that though I just want to drive my car to work and take care of whatever errands I need to do.
