Hoping to get some advice RE the EVSE chargers. I just purchased a Volt, and would like to get Level 2 charger for the garage. It looks like I could add 240V to the garage (two 40A breakers used in main panel for the garage; garage panel is rated for 120V/240V and there are enough empty slots in the garage panel). Does it matter which charger I get? I don't think I need "smart" chargers as the car seems smart enough. What should I expect to pay for charger and installation? Currently, I'm waiting on a quote from AC Electrical for instal.
Thanks!
Congrats on the Volt. What generation?
As was mentioned, if it's the second generation Volt the included Clipper Creek EVSE is indeed 220V compatible via the methods also described in the comments before mine. Yes, you have to wire a "regular" plug to 220V to make it work, but it works, and it charges at about 13-14 amps at 220V. My charge time is in the range of 3.5-4 hours now from dead using the Gen2 clipper creek unit.
If it's the generation 1 charger however it is NOT compatible with 220V, so be sure you know what charger you own.
There's a few versions of the Gen1 charger but they all generally look like this:
The generation 2 Clipper Creek units (which are 240V compatible) look like this:
I was lucky and found someone who had just bought a new Volt but already had a home charging station installed (and apparently didn't want the factory EVSE, even for travelling) who was selling it for $300. I snapped it up, knowing what it was capable of as a Level2 option for home.
Myself, I put the receptacle up in the rafters where nobody would ever be able to reach it without a ladder, much less accidentally plug something 120V into it. If and when we move I'll remove it, or at least remove the plug and terminate the wires in a junction box clearly marked 220V, but in the meantime it works.
For the volt you only need a 20A 240V circuit as the car (and the Clipper Creek EVSE) only draw up to 16 amps at their absolute max which is within code for a constant draw on a 20A circuit. The advantage here is that you can use 12/2 wiring which is quite inexpensive - I used a roll of 12/2 armour cable which was $50 for 75 feet (pre cut) at Home Depot.

Now, this is NOT future friendly, and only applicable for an EVSE that draws no more than 16A like the clipper creek. More amp hungry EVSE's (or even ones capable of drawing more than 16A) would not be code for 12/2, even though the Volt itself will never exceed the 16A - the risk is that if someone else with an EV plugs into it one day and the car negotiates 30 amps for example, the EVSE will try to oblige. But the wiring can't carry it, of course.
I know that if we buy something like a Bolt down the road and I want a faster Level2 rate I will have to run heavier wiring to the garage, but for the meantime since the Volt (or more importantly, the EVSE itself) can't exceed the safe ratings for what I have installed, it's cool.
Anyhow, in the end I installed my own Level 2 for about $75, plus the cost of the EVSE.
