[ausev] A/C in an EV

[Sarah & Erik]

I haven't personally run the numbers, but I remember reading a
discussion about this on the EVDL. I was thinking of doing the same
thing, but I think I remember the consensus being that there wasn't
quite enough "total cold" available in the ice to really do what you
need. It did help though. For not too much outlay, especially if you
already have the radiator, you could build a serious mockup and see
how well it does in your current car. I've got 12V fans that I can
lend if that helps, and I can get you started on some calculations if
you're interested.

I've never seen it done, but an ice water mister would probably work
wonders, especially if it's somewhat dry where you are. As long as the
mist was pretty light, ie not making puddles in your car, it might do
really well.
