I know EPA's range test are a little wonky (using information from the wall unit, assuming a "fill up" at 90% usage, and even averaging 80% and 100% on the 2013's).
But I have been asked a few times and couldn't answer this, and I searched on the leaf boards and still couldn't find a definete answer:
How much actual usable capacity is in the Leaf battery? Is it 22.32 kWh (based on the assumtion that Nissan reserves 7% - 5% top and 2% bottom - from the pack?)? I remember reading many times people stating ~21 kWh as well. Finally some people using Leaf Spy pulled 23+ kWh on new vehicles. I know technically capacity varies from battery to battery and there is some tolerance (i.e. you could be lucky and get a slighty higher capacity battery). But what is the number that everyone has settled on as the actual usable capacity?
The final part is to take that technical usable capacity and extrapolate a miles/kWh per vehicle by year. Using 2.9 us unfair since that accounts for a full 24 kWh usage and not actually capacity usage. It should be easy to figure out once I nail down the actual usable capacity:
2011/2012: 73/X
2013: 75/X
2014: 84/X
I know the calculation results don't necessarily give a true number - but its a metric I have been asked by other leaf owners before, and I was always at a loss since I don't feel comfortable quoting 2.9 kWh/mile, I wanted something more realistic.
