you do not save on electricity: you may save on electricity COST if and only if you have time-of-use (TOU) pricing. if you have flat rate pricing or pricing based on amount used then delayed charging will not have any postive affect on you.

When we first got our Volt we DID use the delay charging feature built into the car with the included Level 1 (L1) charger. We applied for and received a FREE Level 2 (L2) from Detroit Edison. Detroit Edison has two monly payment plans...A usuage plan... you pay for what you use.(This plan has a tiered time of use cost schedule. Rates drop after 11:00p.m and go back up at 9:00a.m.) and they have an unlimited anytime plan for a flat rate of $40.00/month. We have opted for the later ans have discovered that we would have been slightly better off if we had gone with the "Pay for what you use" plan.
LOVE THE CAR! LOVE THE FEEL OF FEELING YOU GET FROM NOT BURNING OIL AND PASSING UP GAS STATIONS!

The time-of-day plan here in the Reno area puts the after 9PM rate at .06785 cents per KWH. The Volt only runs the battery down 10KWH before it switches to hybrid mode (6KWH in Mountain Mode) so a recharge costs about 70 cents here. I've seen 13 KWH posted as how much charge the Volt takes but myself, using a meter, I've never seen greater than 10KWH go back into our Volt. If the battery is not run down the full 10 KWH, the replenishment charge is even less. With my conservative rate of driving, I get an average of 45 miles range in warmer weather, dropping to around 35 in the winter (keeping the car in the garage and remote starting it before we leave to warm it up while still on the charger). I never bothered to check the meter reading on that usage last winter...I'll do that when it gets cold again to see how much power using the heater consumes when on the charger. Normally I give the car 30 minutes to warm up. our garage is not heated but it is insulated so generally never gets below 50 in the winter.

I tried using the delay by cost feature, but it got me into trouble. Since the charging system cannot recognize the difference between charging at home, where you want to minimize costs, and charging somewhere else where you need a charge regardless (e.g. work, airport), while parked at work, the system recognized that my electric rate at home goes up at 10 AM, and so it stopped charging at work, even though I had done the override when I started charging. When I went to go home I had a minimal charge.
If the system simply tapped into the GPS to figure out where you were charging (at home or NOT at home), or even just took the double-plug-in override literally, then the delayed charging by electric rate might be useful to me. But as it is, I have to set my morning departure time such that it will accomplish the 4 hour 240v charge cycle after midnight and before I leave for work.

mejojo: if you are charging somewhere else and your car is set for delay charging, plug the car in, then unplug and immediately plug back in. it will begin charging right away. this is an override feature for exactly that reason.
It is in your owner manual, section 9. in the 2012 manual it is page 9-46, 2013 manual page 9-50:
"Delayed Charging Override
To temporarily override a delayed charge event, unplug the charge cord from the charge port and then plug it back in within five seconds.
A single horn chirp will sound and charging will begin immediately.
To cancel a temporary override, unplug the charge cord, wait for 10 seconds, and then plug the charge cord back in. A double horn chirp will sound and charging will be

I use the override all the time. What I am saying is that if you set the delay charging by electric rate, then use the double-plug-in override, and then a rate increase boundary occurs (in my case, 10 AM when peak rates begin), it will stop charging, despite your manual override. This is on a 2012.
Try the experiment yourself and let me know if you get different results.
