Let's say you want to use the car at 8:00am on Monday-Friday and you want the battery to be charged to 90% and warmed up.
How to configure the app
Configure the app as shown in the screenshot.
What to expect?
Your car starts charging overnight as usual (e.g., according to the charging start time that you have set in the car) until the battery reaches the charge limit (e.g., 85%).

The following graph shows this scenario:
