Either I'm not understanding how to use Stats or the Tesla itself, or there is a missed opportunity that might be fairly common and some low-hanging fruit for developers.
So here is the use case I’m after:
Most days, I only want to charge my battery overnight to 70% to help with battery life. This week, though, on Friday I will be going on a long trip starting right after work at 5:00PM. So I want to set it up so that Thursday night it is charging to 70%, then it stops. But at some time on Friday, it will start charging to 100% so that the car is ready to go at 5:00, and the battery is warm.
As far as I can tell, neither Tesla nor Stats will allow me to do that. The only way I can approach it right now is to wait until after 5:00 Thursday, sit in the car and program it to “schedule” a charge departure time of 5:00 the next day, then go to the charge limit screen and change the limit from 70 to 100%. But even then I’m not sure it will work as I want it to, because I don’t know how long after 5:00 Thursday I have to wait to do that manual process.
SmartBatteryPrep in Stats is working based on a charge start time. So I can’t set it to calculate back based on a departure time. It relies on you to know how much time it will take to go from 70% to 100% in this case. If departure time were added as an option there, it would probably work as long as the calculations were accurate.
On the Tesla itself, the “Scheduled Departure” option has two problems that don't let me do this. It only allows me to:

- Use whatever the existing charge % is.
