I had a complex answer... and then Barry posted this. Now I feel pretty dumb.You can use the charge schedule settings and set your departure time for a time that is later than your actual planned departure time. This way you would be unplugging before the charge has completed.
On my 2011LEAF there are two default settings - 80% or 100 charge. In the early days of the LEAF, drivers wanted a 90% setting instead of 100% to prolong battery life. However that never happened. I am not aware of any selectable option to achieve 90%90% with the Volt but would be useful for someone living at a higher elevation.Oh there are ways, it's just either complicated, not-automatic, or both, so one has to decide if "the juice is worth the squeeze"

Not really, within about 1 mile departure, there is hardly any regen left, even with the regen paddle. It's a weird feeling not having the decceleration. Given that myvolt.com and the OnstarRemoteLink can display %SOC as well as sending command, it's just software to program to stop charging at 90%.It was more important on the Leaf than the Volt since the Leaf battery is much more fragile. Also, the Volt still gives good regen on a "full" battery, something that was not true for the Leaf...
It's more than that, if regen isn't used down hills the brake rotors/pads are used and thus being worn. Regen is best.Depending on how big the OP's hill is, he may be going to all this trouble to leave room for about 10 cents worth of juice.
