Motor Control Module (MCM)
WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
The MCM calculates the battery module SOC and controls the IPU module fan. The SOC is calculated using voltage, temperature, input current, and output current readings of the battery module.
The MCM controls the DC/AC conversion between the battery module 100 V DC to the 3-phase AC IMA motor.
The MCM also controls the IMA motor assist and regeneration.
