Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Motor Control Module (MCM)
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.
