Electrical – On-board Electrical System
From 6 V to 48 V
In the automobile, the on-board electrical system bundles all electrical components. The electrical components include, for example, control units, sensors, actuators, bus systems and energy storage such as batteries and accumulators. Here, the electrical voltage or the rated voltage in the vehicle plays a special role. Earlier, only 6 or 12 V systems were used, but the trend is for a minimum of a 48 V power supply as so-called enabler technology.
