A method for securing safety-relevant loads in a motor vehicle, including a main path arranged between a sub-on-board electrical system for a safety-relevant load of a motor vehicle and another sub-on-board electrical system for a non-safety-relevant load. The sub-on-board electrical system for the safety-relevant load is supplied with power by an energy store. The main path includes at least one switch, and at least one detector for detecting a current flowing through the main path. At least one additional path is provided which is connected in parallel with the main path, the additional path having at least one switch. The method includes: opening the main path upon detection of a critical state, i.e., an overcurrent and/or an undervoltage or overvoltage on the sub-on-board electrical system for the safety-relevant load. The additional path is closed or kept closed while the main path is open. The additional path is subsequently reopened.

Method for securing in particular safety-relevant loads in a motor vehicle

A battery terminal which implements an electronically controlled vehicle electrical system coupling-disconnecting functionality including an electronically controlled power distribution, the battery terminal including a number of switching elements, of which at least some are connected to one another in a star point shape, the star-point connection being provided to be connected to a positive pole of a voltage source.

Battery terminal with a star-point connection switch configuration for a vehicle electrical system

A circuit system having a voltage converter having an input path, an output path, and having a plurality of phases, each phase having at least one half-bridge and at least one fuse, each branch of the half-bridge having a respective MOSFET. The circuit system recognizes a defective MOSFET and controls the MOSFETs of the intact phases in such a way that a sufficiently large current trips the fuse connected in series with the defective MOSFET in order to enable an emergency operation of the voltage converter. A method for operating such a circuit system is also described.

Method for monitoring a battery, evaluation device, and measuring system

A protective circuit assemblage for a multi-voltage electrical system includes: a DC voltage converter provided in the region of the transition between a high-voltage loop and a low-voltage loop; and at least one switch respectively provided in each of the high-voltage loop and the low-voltage loop.
