Abstract: An energy provision system and operation method for a commercial vehicle equipped with the energy provision system are disclosed. The energy provision system includes: a first energy provision unit that is configured to provide energy and includes a first energy provision control unit configured to surveil operation parameters of the first energy provision unit; a second energy provision unit that is configured to store energy and includes a second energy provision control unit configured to surveil operation parameters of the second energy provision unit; and an internal communication unit that is configured to provide data communication exclusively within the energy provision system.

Abstract: A battery device for providing different electrical voltage levels to be used by different electrical consumer devices, particularly for use in a motor vehicle such as a utility vehicle or a commercial vehicle, includes at least one battery storage unit. Each battery storage unit has a low voltage terminal and a high voltage terminal, wherein one or more battery storage units of the at least one battery storage unit has at least one intermediate voltage terminal which is connected between the low voltage terminal and the high voltage terminal of the respective battery storage unit. Each battery storage unit can include a plurality of battery cells connected in series with each other between the low voltage terminal and the high voltage terminal, wherein each battery cell provides a predetermined voltage, and wherein the at least one intermediate voltage terminal is connected between two adjacent battery cells of the plurality of battery cells.

Abstract: An energy supply module for a vehicle includes at least one energy output terminal, at least one energy storage unit, and at least one output energy supply line to connect the at least one energy storage unit to the at least one energy output terminal. At least one energy storage switching unit is arranged in or connected to the output energy supply line between the at least one energy storage unit and the at least one energy output terminal and is configured to at least disconnect the at least one energy storage unit from the at least one energy output terminal.

Abstract: A power supply management system for a vehicle has at least one main power supply unit with at least one main power supply, at least one supplementary power supply unit with at least one supplementary power supply, at least one consumer unit, and at least one power supply line connectable to the at least one consumer unit to supply power from the at least one main power supply and/or the at least one supplementary power supply to the at least one consumer unit. The main power supply and/or the at least one supplementary power supply is/are connectable to the at least one supply line by a main power supply switch and/or supplementary power supply switch, respectively.
