Abstract: The invention relates to a battery unit (10) for use in a vehicle electrical system (50) of a motor vehicle, comprising a battery module (20) for producing a first voltage between a positive pole (12) and a negative pole (11), a battery sensor (52), which is electrically connected to the negative pole (11), and a control element (30), which has a first terminal (31) electrically connected to the positive pole (12) and which comprises a DC-to-DC converter (35).

Abstract: The invention relates to a battery unit (10) for use on an on-board power system (50) of a motor vehicle, comprising a battery module (20) and a battery management system (40) for monitoring and regulating the battery module (20). In this context, a communication unit (30) is detachably connected to the battery management system (40), which communication unit (30) has a receiver unit for receiving data from the battery management system (40), a conversion unit for converting the data received by the battery management system (40), and a transmission unit for transmitting converted data to a control device of the motor vehicle.

Abstract: The invention relates to a battery unit for use on an electrical system of a motor vehicle, comprising a battery module and a coupling unit (30). The coupling unit has a first and a second connection (31 and 32), a first and a second DC converter (41 and 42). The first DC converter (41) allows a bidirectional current flow between the connections (31, 32), the second DC converter (42) allows a current flow from the first connection (31) to the second connection (32). The battery unit comprises a control system. The control system controls the DC converter. The invention also relates to a method for operating the battery unit on a motor vehicle's electrical system. A coupling current (1k) flowing through the coupling unit (30) is measured. When the coupling current (1k) flows from the first connection (31) to the second connection (32) and falls short of a first threshold value, the second DC converter (42) is connected and the first DC converter (41) is disabled.

Abstract: A method of automatically extracting information from an architecture description. A memory resident directed acyclic graph data structure comprising nodes representing instructions and edges whose weights represent dependencies between pairs of instructions is constructed. A list of ready nodes are maintained in the directed acyclic graph. A list of nodes not scheduled is maintained. And, it is determined whether the next instruction to be scheduled is to be taken from the list of ready nodes or from the list of nodes not yet scheduled.
