Hi, I'm using a Level 2 charger at home (240 v) and had set my 2017 volt for delay charging off peak, and time to leave home each day at 7am. However my volt starts charging at 6pm and tells me that it will be completed charging by 11:30pm, right before super off peak rates starts 12am-5am in San Diego. What can I do so can set it to start charging at 12am? Thank you in advance for your help.

Sounds like you need to go into the center screen and set it for charging based on departure time and rate, then tell it when your super off peak rate is.

Which it sounds like you thought you did. Verify settings? Make sure you didn't trip charge immediately somehow, including by a quick plugging and unplugging?

Another trick is to use delayed charging. You can set the car to have the charge complete by 5am. That way it's charging through your super off peak rate. It sounds like your using delayed charging but setting the time to 12am. Delayed charging tells the car when you want to finish charging not when to start.

Set the charge mode to only "Departure". You may have set it to "Rate" or "Departure and Rate". There could also be a defect in your charger (The part that's inside the car), or EVSE, that it's not supplying enough power for the Volt to reach full battery within the time it expected. If changing the charge mode does not work, try using the included portable EVSE.

I suspect (and this is a complete asspull beyond noting some other weird delay issues) that you've got it all set up correctly, but the car knows it's going to need 5.5 hours to charge, you've only programmed a 5 hour window as "super off peak", and it just sees that it cannot comply with ideal and gives up trying to economize. You may want to lie to the car so that it thinks that it has enough time no matter what. Try telling it only about the super off peak time, but set it for midnight to 6 AM instead of midnight to 5, and don't worry about setting a departure time. Then, in the case where it needs 5.5 hours of charging again, it will use the window (because it's big enough), it will start at the right time, and if it runs over the actual super off peak time, the charge cycle will be almost done anyway, and you'll get mostly cell balancing and topping off, and that will use rather less power than the beginning of the cycle does. If it needs a shorter charge time because the battery wasn't zeroed in the first place, it'll put ALL of the charge into the super off peak time.

Hmmm, thank you all for your replies... I will try setting the delayed charging. I had my Leaf for three years and it was so much easier to program it for delayed charging than the volt, sorry to say. Screen is pretty complicated to configure too. Thanks again, and I'll report if I am successful programming it for delayed charging at super off peak rates.
