You, sir, have just described the battery gauge Tesla uses (though the display is a tad fancier). Except they added tick marks every 10% for extra convenience.
I find the 'ignorant masses' are capable of learning. They may not (and very likely won't) fully understand what a kilowatt-hour is, but they seem pretty good at figuring out that they have 20 of them, they drove 80 miles, and now only 2 remain. Also, they cost $0.12 each (or $0.21 each, 70% of which is transmission charge, if you're unlucky enough to have my utility). Makes more sense to give the units their proper name than to make up a non-technical one simply for the sake of being non-technical. -Ben On May 9, 2014, at 1:22 PM, Lee Hart via EV <ev@lists.evdl.org> wrote: > Peri Hartman via EV wrote: >> Well, it doesn't have to be called a kwh meter.
