Denso ES27C AC Compressor control (Toyota/Lexus)
Re: Denso ES27C AC Compressor control (Toyota/Lexus)
Hi, is there any progress in controlling this compressor?
I’m searching information about setting up ch-r compressor(esb20c), because for once, compressor(and bracket) for my car is made from unobtanium, second, with working stand alone controller, many people can adapt ac to cars that in never came with it, or with placement issues.
So im looking to adapt it to normal 12v car, can anyone can help me with it?

Siema Dziku,
As you can read from this post there are two types of this compressors .. one "ES" that is controlled via some proprietary DENSO interface ( whis is partially discovered as you can read in previous posts ), and the newer ones "ESB" that uses LIN interface.
Some hacking is needend for LIN .. i have no time to try that offline, and no acces to real car to sniff.
For planing to use that in some car with 12V supply it is useless - just imagine power requirement .. assume for about 2kW power -> about 170Amps @ 12VDC that is tremendous amount od power/current for 12V circuit, For these comressors you need about 200VDC,- So olny for EV's, hybrids, Stationary.
