Abstract
Battery pack having at least one battery cell arranged within a housing, and a sensor arrangement arranged between the battery cell and an abutting surface. The sensor arrangement has first and second carrier foils separated by a spacer having a recess. A contact arrangement having first and second electrodes are arranged on the respective first and second carrier foils at the recess. In the operating state, the first electrode is spaced apart a first distance from the second electrode and, in a deformation state, a deformation of the battery cell is detected by a variation of an electrical property of the contact arrangement. The second carrier foil has an inlay having a second recess accommodating an activator unit arranged on the second carrier foil such that, after a transition from the operating state in the deformation state, a pressure force is transmitted via the activator unit.
