The disclosure relates to a method for detecting a triggering of a security device. The security device is associated with a battery cell and is triggered if a security-critical situation is present in the battery cell. Initially an actual time path of a parameter of the battery cell is detected. At the same time, an expected time path of the parameter is determined, in particular using a model. Then, the actual time path is compared to the expected time path of the parameter. Finally, based on the comparison, it is determined whether to trigger the security device or not.
