AC.100.3850-EV Electric Car AC Compressor 12V 2300rpm 20cc

How we label data. Confirmed values are read from supplied stock and the manufacturer’s published technical data; reference values are published family designations shown for identification only; anything not published is withheld rather than guessed.

An electric car has no belt-driven accessories, so its cabin cooling depends entirely on an electrically driven compressor. The AC.100.3850-EV is an EV air conditioning compressor built on the proven AC.100.3850 20cc split family: a brushless DC drive, an integrated controller and a fully sealed refrigerant circuit, suited to electric car platforms and electric vehicle AC retrofit projects alike.

As a 12V vehicle AC compressor it runs at the 2300rpm operating point published for the 12V variant of this family (AC.100.3851 data: 600W rated power, 1800W rated cooling capacity, 9.5–17.5V input). The same hardware exists as a 24V unit (AC.100.3850 data: 850W, 2600W, 18–32V input) for trucks and larger platforms. The 20cc electric split compressor runs on R134a refrigerant with POE68 compressor oil.

Production follows ISO9001 auto AC parts process control, with full traceability. Because voltage and controller differ across the family, we confirm your supply voltage and old unit label in writing before quoting, so the electric car AC compressor you order matches the system you are repairing.
