They are not going to let you drain the battery to absolute 0% as this is not very good for a Lithium Ion, or really any battery for that matter. Not sure what the basement battery buffer is but willing to bet at least 2-3 kwh remaining when reading 0%. One time, I drove my Bolt to 0% because the EvGo charger I planned on using was not working. I drove on about six miles and made it home. When I recharged I calculated that the battery actually still had about 5% capacity left at 0% indicated when I evaluated what the charger told me it put back into the battery. At 4.4 miles/kwh that means I still had 3.3 kwh or about 15 miles of range left at 0%. Figure this is pretty typical of all EV makers....excepting Tesla as they do not share a lot of information.My theory is that zero on the guess-o-meter isn't really zero, the same way "E" isn't really empty on an ICE. They may cap displaying the value at 0 (ie not allow it to go negative), but it seems likely that they might leave a couple kwh available for nitwits like me who push it beyond where I'm supposed to.
Just my uninformed opinion.
