we've had our Leaf 2015 for a couple of months now, and while I normally keep it charged in the 20-90% range, it just happened to me twice that I drove it below 17% when the SOC percentage indicator disappears and just says "low battery".
I am not completely sure, but I think I noticed that when I enter the "low battery" state, the mileage indicator is not updated anymore. The last time I tried to pay attention, and as soon as the battery SOC % disappeared and "low battery" was displayed, my mileage estimation indicator said 24km. I then drove at least 3-4km more before reaching home, and did not see the mileage estimation update... until the very end when it actually updated to 25km, so +1km!
I know that in general the mileage indicator provides an estimation, but can someone confirm whether in "low battery" condition the mileage indicator is actually completely useless? Considering that this is the time when you might be looking for a charging station asap, I would say that it is also the time when at least a reasonable estimation of the range left is most useful...
