Abstract
A method detects electrical fault states of a removable battery pack and/or an electrical device, in particular a charging device, a diagnostic device or an electrical consumer, that can be connected to the removable battery pack, using a first monitoring unit integrated in the removable battery pack. The method includes measuring a charging or discharge current using a first current measuring apparatus integrated in the electrical device and transmitting the measured current directly or as a converted voltage value to the first monitoring unit of the removable battery pack, and determining, using the first monitoring unit, based on the charging or discharge current and/or the voltage value calculated therefrom, whether the removable battery pack is operating in a permissible operating range.
