Abstract: 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.

Abstract: A battery pack (174; 174′) having at least one all-solid-state battery cell for driving a motor of a battery-powered portable tool (1) can be charged using regenerated electric power generated by an electric motor (196). However, charging with regenerated electric power might cause damage to the battery pack if the battery cells are not in a state capable of being recharged with regenerated electric power. Therefore, the battery pack includes a battery-condition determination circuit that is configured or programmed to: (i) assess the condition of the at least one all-solid-state battery cell and (ii) generate an electrical signal that indicates whether or not the battery pack is in a state that permits charging using the regenerated electric power.
