The battery is in the cooling loop; I'm pretty sure its involved in the preconditioning if necessary.

You're right I'm adding a bit of extra heat load to the garage. I'm not about to sit in my garage for a bit though, I'm only stepping into it for a few minutes. And then the sun is going to rise and bake it back up to almost 100F again in an hour or so anyways. Making the temp go from 90F to 92-94F in there just doesn't make that much of a difference in the grand scheme of things.

And it is definitely a useful thing to do, as it takes a lot of work to get the car cool, energy that now doesn't have to come from the battery. Its an extra kWh or so that doesn't come from the battery.
