    I wished MS Schedule Time to Charge will have an option that considers the departure time. That is, one programs the time to leave home, and the car will start charging the battery to the set charge limit at the right time so that the car is ready to leave. I think that the car conditions the battery temperature during charging, and it would be nice to drive when the battery is still at its right temperature. Too early charging means the battery is charge but has cooled off so that it needs to be reconditioned again.

    But short of that, I made a spreadsheet to calc the charging time based on my normal driving schedule. The spreadsheet is attached.

    If they'd just steal the implementation used on the Volt, that's be a great start... The scheduling software there is top notch...

    Seconded. This would be great for a range charge where you want it to sit at 100% for as little time as possible. Tell the car you're leaving at 9:30 and it'll hand you 100% at precisely 9:30. That would be nice.

    Especially in the winter, when you'd like to have a warm battery and warm car.

    The Chevy Volt has this function.

    Too bad that UI is a pain to work with. I sometimes drive Volts for work and I just don't bother anymore with that interface.

    My wife's Focus EV has the functionality too. She always leaves home with a nice warm car/battery in the Winter.

    So I developed a bash script that does exactly this and it runs on my wireless router every night when I go to bed. It has different target SOCs for weekdays and weekends. When I go on vacation or need to make a specific change, I simply log into the router's web UI and modify the target SOC.

    I asked a few months back if anyone was interested in a service or small device that would do this, but didn't see much of a response...

    Can you expand a little on how your script accomplishes this?

    You could do this with VisibleTesla daily commands too.

    You can use pytesla to write a python script that does this as well. It should be fairly trivial. I used it to pull stats off of my car to dump into Splunk and it was straightforward.
