METHOD FOR CHECKING INSULATION BETWEEN LOW-VOLTAGE NETWORKS OF A VEHICLE, AND LOW-VOLTAGE SUPPLY ARRANGEMENT FOR A VEHICLE

Abstract: technologies and techniques for checking insulation between low-voltage networks of a vehicle, wherein the low-voltage networks are galvanically separated and each comprise a dc/dc converter, an energy storage device, and a supply bus for supplying low-voltage consumers. the dc/dc converter is connected on one side to a high-voltage supply and on the other side to the energy storage device and the supply bus. the method includes: applying a voltage change to the high-voltage supply or the supply bus of one of the low-voltage networks using the dc/dc converter of said low-voltage network; detecting a voltage on each of the supply buses of at least the other low-voltage networks; evaluating the detected voltages; and deriving and outputting a test decision. a corresponding low-voltage supply arrangement is also disclosed.
