Abstract: The invention relates to a method for checking a protection method for protecting a battery device (100), in particular an electrode of the battery device (100), comprising the following steps: monitoring at least one electrical battery parameter (EBP) of the battery device (100); monitoring at least one operating parameter (BP) of an operating current (IB) of the battery device (100); monitoring at least one disturbance parameter (SP) of a disturbance current (IS) of the battery device (100); comparing the monitored disturbance parameter (SF), the monitored operating parameter (BP) and/or the monitored battery parameter (EBP) with at least one comparison parameter (VP) based on the battery parameter (EBP) and/or on the operating parameter (BP).

Abstract: The invention relates to a method for protecting a battery device (100), in particular an electrode of the battery device (100), having the following steps: determining at least one electrical battery parameter (EBP) of the battery device (100), determining an operating parameter (BP) of an operating current (IB) of the battery device, calculating a disturbance parameter (SP) for a disturbance current (IS) on the basis of the operating parameter (BP), generating the disturbance current (IS), and applying the disturbance current (IS) to the operating current (IB).
