System and method for providing redundant electric power

1. A system for providing redundant electric power to at least one vehicle component, comprising:

at least one power management unit connectable to a vehicle power network; and

a plurality of storages coupled to the at least one power management unit for receiving electric power to be stored in the plurality of storages and for delivering power between the plurality of storage units to enable redundant electric power supply,

wherein the at least one vehicle component is connectable to at least two of the plurality of storages to enable a redundant electric power supply through the at least one power management unit and the vehicle power network, wherein the plurality of storages each comprise at least a first set of output terminals and a second set of output terminals for connecting vehicle components, wherein the plurality of storages are configured to provide the first set of output terminals with a different voltage level than the second set of output terminals, and

wherein the at least one power management unit comprises:

a charger for providing a charging power to the plurality of storages;

a switch for interrupting a connection to one or more of the plurality of storages; and

a logic circuit for controlling the charger and the switch.

2. The system according to claim 1 , wherein

one power management unit is coupled to multiple storages of the plurality of storages, and

the switch is adapted to interrupt one or more of the multiple storages coupled to the one power management unit.

3. The system according to claim 2 , wherein

the multiple storages each comprise a storage element and a further logic circuit for monitoring a state of a respective storage element.

4. The system according to claim 1 , wherein

each power management unit is associated with one of the plurality of storages with a storage element, and

the logic circuit is further adapted to monitor a state of the storage element in the associated storage.

5. The system according to claim 1 , further comprising:

a vehicle communication network, wherein at least one of the logic circuits of the power management units is adapted to provide status information about the plurality of storages to the vehicle communication network.

6. A vehicle comprising:

at least one vehicle component; and

the system for providing redundant electric power to the at least one vehicle component according to claim 1 .

7. A method for providing redundant electric power to at least one vehicle component, comprising:

managing a power supply by at least one power management unit connectable to a vehicle power network, wherein power is supplied to and stored by a plurality of storages coupled to the at least one power management unit; and

providing power to the at least one vehicle component by at least two of the plurality of storages to enable a redundant electric power supply, wherein the plurality of storages each comprise at least a first set of output terminals and a second set of output terminals for connecting vehicle components, and wherein the plurality of storages are configured to provide the first set of output terminals with a different voltage level than the second set of output terminals,

where the at least one power management unit comprises:

a charger for providing a charging power to the plurality of storages,

a switch for interrupting a connection to the plurality of storages, and

a logic circuit for controlling the charger and the switch.
