I've been deliberately running my battery down into the "quarter tank" range to gain confidence with that. The most obvious thing I've noticed is an indicated 185 km range at about 50% indicated, which is about 43% of full rated range, 426 km. At first, i worried this might reflect loss of battery capacity, even though I've only had the car a couple of months and less than 5000 km. Then I made my first supercharger stop and range charge, and it charged up to a full indicated 425 km range at 100% on the gauge. So evidently, the charge gauge graduations are not linear in rated range. Has anyone else noticed this? Has anyone else mistakenly attributed this to range loss as I did? Thanks for any comparison notes.
