departure vs departure/rate charging

I've struggling with this issue

Super off peak 12am-6am
Off peak 6am-9am
Peak 9am-6pm

If I plug in and departure is selected, it will charge from 10pm to 8am (average)
If I plug in and departure and rate is selected, it will charge from 6pm to 6am (average)

Already having to select 12amps is a giant pain in the ass, now having to check and then switch between the charge modes is ridiculous

I suggested that when you open the charge door it should ask what amperage you want, real simple and foolproof

The factory Volt rep wrote that this is normal and that it starts charging at the earliest possible time in off peak (if required) then stops charging then starts as soon as super off peak time is reached.

I work a lot with 12v charging systems and find this a strange thought.

It should be back tracking from departure time and start charging as late as possible based on rate, rather then as early as possible.

I've copied his email below:

When you are in Departure mode (shown in "Departure.jpg"), the system will calculate back, starting from the departure time, to determine when the charging will actually start. With this method, charging would start at 10:50PM and take 9.5hrs.

When you are in Rate & Departure mode (shown in "RateandDeparture.jpg), the system will do the following:
1. Figure out how much time in the OFF PEAK mode it has to charge. In this case it was 6hrs.
2. From there, it will look for MID PEAK charging windows it can charge in. In this case, this is from 6:00PM-12:00PM.
3. Starting from the beginning of the MID PEAK charging window, it will begin charging for 3.5hrs, then stop until 12:00AM, which is the beginning of the OFF PEAK charging window. At that point, it will do the remaining 6hrs of charging.

Therefore, it will take the same amount of overall time to charge, but it looks to fill the OFF PEAK time and then move the remaining charging to the earliest MID PEAK time.

programming charge times

get a 240v charger if possible. In this way you can eliminate using the departure AND rate time mode of scheduling. I just load 5 am departure time for everyday and it starts charging after midnite (off-peak) and is done charging with time to spare by 5am
