New to Tesla and I'm trying to wrap my head around the miles remaining on the display at the top of the screen. I have a 2021 LR-AWD and have a few questions.
For reference, I charge at home to 90%. After the charge, the displayed range is typically 315 miles.
1) Is the displayed range supposed to adjust based on recent driving habits? Mine is always the same (when charged to 90%) no matter how I've been driving.
2) Recently, after driving 137 miles, the remaining range was 113 miles, implying that the range before driving those miles should have been 250, not 315 as was displayed. Okay, I get it -- the computer doesn't know how you're doing to drive, but shouldn't it adjust to your driving habits at some point? Then when I recharged that evening, the range shot right back up to 315, not 250. Is this expected behavior? Why?
3) At the same point in time as #2 above, the remaining battery charge was 32% (from 90%), representing a 58% use of battery charge. The "since last charge" displayed 34 kWh of use (and 244 Wh/mi). If the battery lost 34 kWh over the 58% consumption of it's capacity, this would imply that a 100% charge is 34 kWH /58% = 58.62 kWh battery capacity, not 75 kWh to 82 kWh as many people report. Does this make sense, and if so, why?
4) If my average driving habits are 244 Wh/mi, and usable battery capacity is actually 75 kWh, this would imply a total range of 307 miles, not the 250 miles or so that I'm achieving given that rate of consumption.
I know there are reasons for these behavior items that I don't understand. I'm hoping someone can explain it all.
FWIW, "sentry mode" is off, and I rarely wake the car up when it is parked.
