Method for detecting electrical fault states of at least one interchangeable battery pack and/or an electrical device that can be connected to at least one interchangeable battery pack and system for carrying out the method

摘要

The invention relates to a method for detecting electrical fault states of at least one interchangeable battery pack (10) and/or an electrical device (16) that can be connected to at least one interchangeable battery pack (10),in particular a charger (18),a diagnostic device (20) or an electrical consumer (22),by means of a first monitoring unit (56) integrated in at least one interchangeable battery pack (10) and a further monitoring unit (60) integrated in the electrical appliance (16). It is proposed that both the first monitoring unit (56) and the subsequent monitoring unit (60) count faulty loading or unloading operations. Further, the invention relates to a system comprising at least one interchangeable battery pack (10) and an electrical device (16) for carrying out the method.
