Zusammenfassung:	A method for determining a state of a fuse in a battery pack is provided. The battery pack comprises a first string comprising a first string fuse; at least one parallel arrangement comprising a battery cell and a resistor; and a first ammeter. The parallel arrangement is configured to be changeable between a connected state wherein the resistor is connected in parallel to the battery cell and a disconnected state wherein the resistor is disconnected from the battery cell. A second string comprising at least one battery cell is connected in parallel to the first string. The method comprises changing the at least one parallel arrangement of the first string to the connected state, and measuring a current passing through the first string. In an event that the change in the first current does not exceed a threshold, the first string fuse is in a blown state.
