You would need a lot of ice, hundreds of pounds, to provide the
refrigeration needed.
12,000 BTU/hr is the rating of a typical car air conditioning unit. This
is literally equivalent to one ton (2000 lbs) of ice per day.
"Hacking" some OEM EV air conditionaing, like from a Prius, is likely
the best option. There are also inverter driven (VFD) home compressors
that would likely work as well, but aren't as rugged as the OEM EV air
conditioning compressors.
I would investigate small, single phase input, three phase output,
variable frequency drives (VFD) instead of building my own inverter from
scratch. Like a TECO:

Likely will run nicely from DC. Certainly cheap to try.

If A/C demands aren't great, I've wondered if you could get away with a
cooler, some ice packs, some water to carry the "cold" and a circulation
pump to run the water through a tubing network installed in a seat cover.
I know it sounds crude, but that's how NASA cools astronauts. Almost all
the energy would come from the freezer that chills the ice packs. Could be
inconvenient, but if the car is for commuting, just throw ice packs in the
fridge at work.

So, I can imagine all sorts of ways that one might run air conditioning in
an electric vehicle, but I'm sure others have actually tried and done
different ways and likely figured out the best general approach.
Any of those others reading these words and care to point me in a good
direction?
This'll be starting from scratch in a vehicle that never had air
conditioning in the first place but for which both factory and aftermarket
air conditioning systems are available that run off of a pulley on the ICE
engine.
Thanks,
