A power-distributing device for a vehicle electrical system of a motor vehicle may include at least a first power source terminal and a second power source terminal, at least a first safety supply terminal and a second safety supply terminal, a coupling unit to electrically couple the power source and safety supply terminals, and, for each of at least two power source terminals, a source switching element is to electrically couple the first and second power source terminals to the coupling unit, depending on a switching state. In an example, the power-distributing device may have, for each of at least two safety supply terminals, a supply switching element to electrically couple the first and second safety supply terminals to the coupling unit (), depending on a switching state.

Power-distributing device and motor vehicle

A power network for a motor vehicle includes a first partial power network connected to a supply potential, a second partial power network, and a coupling element which couples the second partial power network to the supply potential via the first partial power network. The coupling element has a reversible disconnect function, such that the coupling element reversibly decouples the first partial power network from the second partial power network based on a physical value of the first partial power network.

Power network for a motor vehicle and method for operating a power network for a motor vehicle

A battery storage system, for supplying electrical power to at least one electrical vehicle function, which is redundantly connected to the battery storage system by a first supply branch and a second supply branch includes a first connection and a second connection configured to connect to the first and the second supply branches; at least one ground connection; a connection line, which connects the first and the second connections; a cross-isolating switching apparatus arranged in the connection line and configured to interrupt the connection line; a first energy storage unit connected to the connection line between the first connection and the cross-isolating switching apparatus; and a second energy storage unit connected to the connection line between the second connection and the cross-isolating switching apparatus.
