Vehicle
Control Unit
The vehicle control unit (VCU) is the core system and runs software that controls the vehicle’s functions. It interfaces to all the sub-systems required to charge the vehicle, store energy, create energy, drive the powertrain and manage the flow of energy, and integrate with vehicle operational systems. Its function is to monitor and control the vehicle during charging, wake up, operation and shut down of the vehicle
