Tesla air conditioning retrofit

I might as well start out with...

@PetroleumJunkie412


Has anyone ever tried to retro fit a Tesla ac system on anything yet? Im sure it can be done.

I am interested in this for my truck and a 88 T-top GT that got a 4v swap done already but with the turbo going on we are trying to save on space up front.

Prius and volt were my target.

Theres two compressors in each, a big one to chill off the cabin, then a small one to maintain temperature.

I've been interested in both, one as a boost chiller, and the small one to cool off the cab.

I will not put anything off a Tesla on my vehicles. The only reason I dont run them off the road is that they're made in the USA.

Elon can burn in what the Christians call hell for all I care.

Yes, Factory 2/60 AC, 2 windows down at 60MPH


Very nice electric AC compressor setup in this video

I am dubious about the possibilities for using any hybrid electric AC system on any non-hybrid vehicle.

Hybrids need a special PAG oil in the AC system because regular PAG is conductive. This wouldn't be an issue, but hybrid AC compressors are high-voltage devices, running off the HV traction battery. Doesn't sound like much of an issue, until you consider that regular automotive electrical systems run on 12-14V, a normal household system is 110-220, and hybrid HV system usually runs in the neighborhood of 300V.

I guess what I am asking is, how are you going to power the unit?

For some reason, I remember the Toyota/GM unit being 12 or 24v. Cant recall, notebook in my desk at work.

Let me guess, ford is using 300v? Along with their soy and coffee based plastics, diamond encrusted washers, frequency based map sensors.... etc.

Don't forget acid reflux capacitors.

Well, I have yet to actually test the voltage to the compressor with a meter, but it has two big orange wires with high voltage warnings all over them.

Some numbers I picked up

Smaller car, like Ranger cab, AC uses about 4HP and 3,000watts, 3kW

Larger car/suv, may use 6-7kW

Electric cars use 1.8kW to 2.5kW compressors

That doesn’t necessarily mean anything... most safety warning are useless.

Electricity is just a bunch of little hoobajoos dancing around trying to more positive.

 

[RonD]

Well no turbo lag with electric version, and that's a good thing

Except when the sign says do not feed the bears, man you better not feed the bears...
