Thread: Electric Vehicles - Air Con

Yep, they are fairly readily available - they draw a **** load of current.

Plenty out there like this - StreetFX Motorsport and Graphics – RENCOOL MD18 12v OR 24v Electric Air Conditioning Compressor For Automotive/Race or Construction equipment – As used in WTF-86

You can get a 12v ac compressor.

Tesla run heater matrix and AC comp directly off high voltage battery pack. As high as 400v

What's the application?

Don’t they just!

Certainly wouldn’t want to leave it running the vehicle off.

Depends on the set up. You can sleep in the back of a Tesla and have the AC running all night. Uses up a few measly percent

As it would at night when the heat load is a couple of hundred watts and you are sleeping on a 60KWh battery.

Frankly at 400V and 60KWh a Tesla battery would power my House ducted A/C for close to 3 days (72 hrs) in the heat of summer. I could hook it straight up to the PFC rectified bus and just switch it on. I'd have a bugger of a time driving the house anywhere though.

BLDC compressors are the future as the cornerstone of a fully hermetic automotive system with no potential for leaks. That's a relatively long way off however.

Full hermetic systems have been around for years,and yes they can all leak refrigerant,no matter how well they are built......

EV don't use the 12V supply for AirCon, The 12V battery is minuscule and is used for lights / contactors etc , if the 12V battery goes flat the EV is dead.
