Switch arrangement and method for controlling a switch arrangement

A method for controlling a switch arrangement for providing a plurality of alternative distribution paths in a system for distributing electrical power in a vehicle including a plurality of electrical power supplies and a plurality of electrical loads, a first switch connected to a first electrical element, the first switch having an open state or a closed state, a second switch connected to the first electrical element and a second electrical element, the second switch having an open state or a closed state, and a third switch connected to the second electrical element and a third electrical element, the third switch having an open state or a closed state, wherein each of the first, second, and third switches is independently controllable, the method comprising:

• selectively operating each of the first, second, and third switches to its open or closed state, based on detection of both a first anomaly and a value of at least one current flowing in the system for distributing electrical power in the vehicle, to interconnect at least two of the first, second, and third electrical elements to establish a first one of the plurality of alternative distribution paths to connect one of the plurality of electrical power supplies and one of the plurality of electrical loads;
• and
• selectively operating each of the first, second, and third switches to its open or closed state, based on detection of a second anomaly in the system for distributing electrical power in the vehicle, to interconnect at least two of the first, second, and third electrical elements to establish a second one of the plurality of alternative distribution paths to connect to connect two of the plurality of electrical power supplies, wherein a first one of the two of the plurality of electrical power supplies is chargeable by a second one of the two of the plurality of electrical power supplies.

A non-transitory computer readable storage medium having stored computer executable instructions for controlling a switch arrangement for providing a plurality of alternative distribution paths in a system for distributing electrical power in a vehicle including a plurality of electrical power supplies and a plurality of electrical loads, the vehicle having a controller and a first switch connected to a first electrical element, the first switch having an open state or a closed state, a second switch connected to the first electrical element and a second electrical element, the second switch having an open state or a closed state, and a third switch connected to the second electrical element and a third electrical element, the third switch having an open state or a closed state, wherein each of the first, second, and third switches is independently controllable, the computer executable instructions configured to cause the controller to:

• selectively operate each of the first, second, and third switches to its open or closed state, based on detection of both a first anomaly and a value of at least one current flowing in the system for distributing electrical power in the vehicle, to interconnect at least two of the first, second, and third electrical elements to establish a first one of the plurality of alternative distribution paths to connect one of the plurality of electrical power supplies and one of the plurality of electrical loads;
• and
• selectively operate each of the first, second, and third switches to its open or closed state, based on detection of a second anomaly in the system for distributing electrical power in the vehicle, to interconnect at least two of the first, second, and third electrical elements to establish a second one of the plurality of alternative distribution paths to connect to connect two of the plurality of electrical power supplies, wherein a first one of the two of the plurality of electrical power supplies is chargeable by a second one of the two of the plurality of electrical power supplies.
