Capacity bars are not linear. The 12 bar display is actually anything from 85% to 100% capacity. Below that, every bar stands for 6.25% if I am not mistaken (quoting from memory) So 7 bar capacity can be as low as 100 – 15 – 4 x 6.25% = 60% so less than 15kWh. Also, there is a reason it is called the GOM (Guess-O-Meter). My Leaf has 8 capacity bars. I can drive home and go from 12 quickly to 10 or 9 and then arrive home with only 6 or 7 bars left. Then drive to work starting with that half charge and arrive at work with still 3 bars left…. I have noticed that range bars are not linear, so you can’t say X bars is so many kWh left. GIDs are a better measurement, so use LeafSpy and you can much better judge what your Leaf is doing. Hope this helps, Cor.

Temp about 45F Heat on: drawing average of about 1 kW "other systems" drawing about .25 kW Drove 14 miles, went from 12 range bars to 5 bars (full charge level is 9 capacity bars) Average 3.2 miles / kWh Duration about 1 hr. Driving pretty carefully - usually only 2 "balls" on the usage meter. For electrical systems, I estimate I used about 1.25 kWh. For traction, 14 / 3.2 = about 4.5 kWh Total: 5.75 kWh. According to https://electrolease.nz/blog/nissan-leaf-range-charts-and-tables.html 5 bars equates to about 45% charge remaining. Assuming that the capacity bars are linear and I'm between 8 and 9, the battery should have somewhere near 17 kWh (24 originally). 45% of that is about 7.5 kWh remaining charge. Add in what I've used, 5.75, makes 13.25 kW - but should be around 17. Plus extrapolating the mileage: 14 / 45% = 31 miles estimated total range. What happened to the other 4 kWh? And, am I the only one who get 31 miles per charge? This Leaf has had miserable winter range since the beginning. Still don't know why.
