My observation has been that unstated battery losses are at about 20%.
For example, your car states you have 200 miles available to drive. But in reality, you can probably get about 160 Miles (give or take).
Thus the true stated mileage of your Tesla vehicle is about 20% less than what’s being advertised…
You think you’re going to get 235 miles of use, but only get about 190 Miles.
This is from normal driving, street and highway.
** Recent Example:
210 Miles Available.
118.5 Miles driven since last charge
35.4 KWH since last charge
298 WH/Miles since last charge.
Battery Left Over indicator Reads: 54 Miles
A phantom loss of 37.50 Miles or 17.85%
