They're going on the short list of options, especially in light of subsequent posts.

Were I going a traditional BEV route, with the electric motor going in the same general physical space as the V8 currently is, that'd probably be an ideal solution. But it seems likely that, one way or another, the electric motors are going to wind up on the underside of the car somewhere below the cabin, so a physical coupling to an auxiliary shaft probably isn't going to be practical, alas.

It's a splash of cold water that's making me think that any sort of electric solution is going to have to beat just turning on the V8 and letting it idle to power the air conditioner, even in electric mode. That'll require the ability to decouple the accelerator pedal from the carburetor as discussed yesterday, but that's likely something that'll need to be done regardless. (Another thought on that is a wireless electronic throttle on the carb, though there's a lot to be said for something mechanical.)

I'll admit that I know of no such advances, and was simply guessing that beer cooler cooling capacity would likely be good enough for batteries, considering most people don't cool batteries at all. I likely wouldn't be worried about active cooling for batteries were it not for the fact that I'm in Arizona. Maybe I should start over: _should_ I be worried about active cooling for batteries? And, if so, what're good ways to go about it?

If I have the math right, that's all of 7 - 10 amps at the 144 volts I'm planning on for the traction battery. And, for long trips that would run down the traction battery, I could always (once I've got all the programming figured out) run the regen on the motors (with motive power, of course, coming from the V8) at just enough load to power the air conditioner. I'll have to work some numbers with the power requirements for those Classic Auto Air and Vintage Air units Jerry suggested.

Fortunately -- or not -- heating isn't much of a concern here in Arizona. Quite the opposite, in fact.... A wimpy, underpowered ceramic heating option may well meet the 80 / 20 rule, with the V8 providing heat as a fallback in those very rare circumstances that I might need more than what a small heater plus a jacket would take care of. For that matter, no heater at all is probably "good enough," at least initially.
