Beschreibung
Zusammenfassung:	A method detects electrical fault states of a removable battery pack. Cell voltage values of a plurality of energy storage cells of the removable battery pack are detected by a first monitoring unit integrated in the removable battery pack and a voltage of the removable battery pack is detected by a further monitoring unit integrated in an electrical device, in particular a charging device, a diagnostic device or an electrical consumer, that can be connected to the removable battery pack. The cell voltage values detected by the first monitoring unit are transmitted to the further monitoring unit. The further monitoring unit sums the cell voltage values and compares this with the voltage value of the removable battery pack.
