The electronic controller unit of electric or hybrid vehicles does NOT include ______.

  • A.sensor
  • B.interface circuitry
  • C.processor
  • D.power converter

Answer: D

The electronic controller (control unit) of an electric or hybrid vehicle takes in signals from sensors, interfaces them through interface circuitry, and processes them in a microprocessor to give commands to the drive and the battery management. These are its parts.


The power converter (the inverter or DC to DC converter) is the power electronic stage that carries the motor current and is controlled by the controller, but it is a separate unit and not part of the controller itself. The answer is power converter, option D.
