There are a bunch of people that charge to 80% or 90% and then project their total range at 100%.
Well, I've found out the grid lines in the display are not set to 60%, 70%, 80% or 90%. At least in my car.
Could you check in yours?
These lines are clearly set at 61%, 71%, 81% and 91% in my car.
You can test it in different ways.
The easiest way is to set the car to 90% using the App. The grid lines in the App are not distorted.
So, set the car to 90% in the App and then check in the car where is the charging line.
You may see it's well above the 90% grid line as in my car.
You can also test it by setting the car to charge to 80 or 90% (in the car's display) and then set the display to %.
I always get 81% or 91% when the charging finishes instead of the 80% or 90%.
Is this a normal behaviour shared by all cars or only by a subset?
There’s no dirty trick going on. The problem with using the slider in the car or the tesla app is that there’s no feedback other than 90% and 100%. So it’s virtually luck to get it exactly to any other percentage. You need to use an app like stats or any other app that lets you set the charge rate to a specific percentage if you want to be exact.
