Function of the on-board network
The vehicle electrical system includes all electrical and electronic components and control units in a vehicle, supplies them with power and enables the flow of information.It usually supplies a voltage of 12V.However, some modern vehicles now already have 48V electrical systems.
In addition to the power supply, it enables communication between up to 100 control units via the CAN bus. A generator, colloquially known as an alternator, keeps the on-board voltage constant and charges the battery.This is driven by the vehicle's V-belt. An alternator regulator controls the current in the alternator by briefly switching it on and off.
