Yes, you are correct about being crazy and buying a black car down here... I think the reason I did buy the black Volt, is when I sat in it at the dealership, it was the only Volt they had and was out in the lot in the sun... I sat there for 40 to 50 minutes, marveling at the magnificent technology, my brain suffered heat damage and thus I sprang into action and bought the "Black Rascal." Had it been a white Volt, I'd probably still be riding my burro back and forth to work... but I'm glad I sat in that black Volt and came to my senses...
I never even considered the Nissan... Too many reasons to go with the Volt, however I was not aware of the Nissan being air cooled in the charging mode... I knew the folks at GM needed to hit a proverbial "home run" out of the ball park when they designed the Volt, Now after owning one for several months, I'm beginning to thing the guys and gals in Michigan hit it not only out of the "ball park" but across the country... it's just brilliant.
I already saw what the Phoenix heat did to the air-cooled batteries in my, Honda Civic Hybrid. Battery performance fell way off by the middle of the first summer and didn't come back in the fall. Meanwhile Prius liquid cooled batteries are doing just fine. That was enough to convince me...

The EVSE might be another matter, however. AFAIK, all of them are passively cooled, and some of them tend to run a little hot to begin with. I'm not sure, but I suspect most or all of them do have thermal overload trips - which would deny the car power until the cord cools off enough.
