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

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
