I'd like to take advantage of off-peak hours for charging, obviously. But...
In the settings, there is only one time that you can set; for when the off-peak hours end. But there is no setting for when they start? How does it know when to start charging?
If you aren't going to leave until 2 hours after peak hours begin, there doesn't seem to be way to charge most of the way during off-hours, but have it continue to trickle charge or keep the battery warm so you can be ready to go.
It feels like you should have facility for telling the car when off-peak hours are, and then if you say a specific departure time is needed, it should do the work for you.
