  • Method for testing a cell monitoring unit, and testing device
    Patent number: 12105155
    Abstract: A method is used to test a cell monitoring unit, in which method respective cell voltages are applied to cell voltage connections of the cell monitoring unit. A measurement is then carried out on a cell monitoring unit which is in operation in order to determine whether a respective current is flowing via at least one cell voltage connection, and a fault message is output if this is the case. A testing device is used to test a cell monitoring unit and has at least one current measuring apparatus for measuring currents at cell voltage connections of the cell monitoring unit. The testing device is configured to carry out the method. The method and testing device are applicable in particular to testing a cell monitoring unit of a vehicle, in particular of an electric vehicle.
