First off, everyone should send a big thanks to forum user NAMJA for trusting me and sending me his brand new 2016 Volt EVSE so I could open it up, poke around in it, and possibly fry it!
After exhaustive research of the internal components, I came to the conclusion that it will happily and safely handle 240VAC allowing the Volt to charge at L2 speeds. This means ZERO modifications to your EVSE on the inside or out to achieve this. All you need is an adapter to allow the EVSE's 5-15 plug to go from Hot-Neutral-Ground of 120VAC to Hot-Hot-Ground of 200-250VAC, like on a dryer outlet.
Since the EVSE is originally rated for 120VAC on a 15A circuit, it will only advertise 12A down the pilot wire (80% constant load x 15A = 12A). This means you will be doubling your charge rate over the L1 for a maximum of 3kWh. Now, I know the Gen2 can handle 3.6kWh, but the wire gauge wouldn't be safe to much higher amperages and I'm not about to modify the pilot signal to advertise 15A.
More good news, this EVSE is made by Clipper Creek!
EVEN MORE good news for those of you charging at L1 speeds, the NEMA 5-15 plug on this EVSE has a built-in thermal sensor! NO MORE MELTED SOCKETS! At first, I was just going to replace the whole input cord, but that would get rid of that safety feature. Adapting to 5-15 and keeping that thermal sensor is best.
After wiring up an adapter for this EVSE, I plugged it into a 240V outlet and charged my Tesla at 12A for 30 mins or so. Nothing got hot, at all. Clipper Creek does a great job on their EVSEs and it's good to see they've stuck to the larger gauge wire as compared to the thinner/hotter Lear configuration on the 2010, 11, 12, and 15.
Here are the pictures of the EVSE's guts along with some action shots of it charging on 240VAC in my Tesla.

If anyone would like me to make an adapter for them, let me know.
Make sure your EVSE looks like this!
