Yeah, for me too it stopped the charge at 6am despite asking for 745am departure. Also, at 545 am it had the cabin preconditioning on, the car was parked outside because garage was full of stuff last night, and the inside of the car was 22C at 545am.....charge stopped at 6am, and at 6:10am it was 0C in the car again....so lots of wasted energy to heat up the cabin 2 hours before I wanted to leave.
Seems we can't tell the car that TOU is at a different time to actually have it end when we tell it, so I assume an update will happen.
For reference, I started charging last night with 100 km of range, and asked for 60% charge. It actually did calculate the start time properly even though I've limited my charge rate to 28Amps and not at 32....so at least its doing the math right
