DESCRIPTION AND OPERATION
A/C Inverter Motor Controller
The A/C compressor is supplied power by the A/C
inverter motor controller (IMC), which is located in
the underhood compartment next to the traction
battery charger on the passenger side. Traction
battery voltage is fed to the A/C IMC through the
high-voltage power distribution box (HVPDB), and
this is converted into high-voltage alternating
current. Six insulated gate bipolar transistors are
incorporated into the A/C IMC for efficient
operation. Coolant is circulated through the
controller to remove heat that is generated during
operation.
Air Conditioning
The A/C system on the Electric Ranger uses a
high-voltage motor driven compressor. The
evaporator and plenum assemblies are new, but are
located in the same position as the gasoline-powered
Ranger. To remove and install any components
other than the compressor and the A/C inverter
motor controller, refer to the Ranger service
manual.

Based upon driver demands, the interface adapter
assembly (IAA) module varies the power output of
the A/C inverter motor controller (IMC), which
controls the compressor output. The A/C system is
limited to cooling the passenger compartment to
18.5°C (65°F) in order to conserve traction battery
power.
Compressor
The compressor for the Electric Ranger is located in
the underhood compartment below and in front of
the traction battery charger. The compressor is
driven by an electric motor that is powered by high
voltage from the A/C inverter motor controller
(IMC). Compressor speed is varied based upon
cooling demands. The compressor has a maximum
speed of 7812 rpm and is protected by an
over-temperature sensor. The oil used in the A/C
system is a new Polyolester type and is not
compatible with any other A/C oil or leak detection
dyes. Using any other oil may cause damage to the
A/C system.
