This view shows the contents of the "IPU" compartment, immediately behind the driver and passenger
seats. This compartment contains the following components:
• Motor Control Module (MCM): This is the metal box located in the upper right corner, which
controls when the motor operates in assist or regeneration mode, and controls the degree of
assist/regeneration.
• Battery Condition Module (BCM): This it the metal box to the left of the MCM, just right of
center. This tracks the battery state of charge and decides how much energy can be supplied to
or delivered from the battery.
• Battery Module: Located below the MCM and BCM, this is the Insight's 144 volt primary
battery pack.
• Battery Module cooling fan, located in the bottom right portion of the picture. This two speed
fan draws air from the cabin, behind the right seat, and pulls it through the battery pack.
• Motor Drive Module (MDM): This is the component located in the upper left corner of the
picture. The Motor Drive Module contains the switching electronics used to bidirectionally-
directionally send power between the Battery Module and the IMA Motor, based on
instructions provided to it by the Motor Control Module (MCM).
• Heat Sink: This is the duller colored component located next to the MDM, which absorbs and
dissipates heat produced by the MDM and DC-DC Converter.
• DC-DC Converter: This is the component located to the right of the Heat Sink. The DC-DC
Converter converts the 144 volt power supplied by the IMA motor and/or Battery Module into
12 volts to supply the Insight's conventional 12 volt accessories.
• Power Control Unit (PCU): The MDM, Heat Sink and DC-DC Converter are collectively
known as the Power Control Unit.
• PCU Cooling Fan: This is located in front of the heat sink, and draws air through the heat sink
to aid in cooling of the PCU.
