Vehicle Electric System, Device for Controlling a Vehicle Electric System, and Vehicle with a Device

A device for controlling a vehicle electrical distribution system of a vehicle, the device comprising:

• a first current terminal configured for electrical connection to a first vehicle electrical distribution system branch having a dynamic electrical consumer,
• a second current terminal configured for electrical connection to a second vehicle electrical distribution system branch having a sensitive electrical consumer,
• a first controllable switching device arranged between the first and the second current terminal and configured to switch between:
• a first switching state that unidirectionally conducts current only in a first current flow direction from the first current terminal to the second current terminal, and
• a second switching state that bidirectionally conducts current both in the first current flow direction and in a second current flow direction from the second current terminal to the first current terminal.

A vehicle, comprising:

• a vehicle electrical distribution system comprising:
• a first vehicle electrical distribution system branch having a first, dynamic electrical consumer,
• a second vehicle electrical distribution system branch having a second, sensitive electrical consumer,
• a first controllable switching device arranged between the first and second vehicle electrical distribution system branches and configured to switch between:
• a first switching state that unidirectionally conducts current only in a first current flow direction from the first vehicle electrical distribution system branch to the second vehicle electrical distribution system branch, and
• a second switching state that bidirectionally conducts current both in the first current flow direction and in a second current flow direction from the second vehicle electrical distribution system branch to the first vehicle electrical distribution system branch;
• and
• a device for controlling the vehicle electrical distribution system, the device comprising:
• a first current terminal configured for electrical connection to the first vehicle electrical distribution system branch, and
• a second current terminal configured for electrical connection to the second vehicle electrical distribution system branch,
• wherein the first controllable switching device is arranged between the first and second current terminals.
