Abstract: A battery cell includes a housing, an electrode stack assembly, and at least one terminal assembly. The electrode stack assembly is arranged in the housing and includes first electrode assemblies and second electrode assemblies. The first electrode assemblies include first electrodes and first strip elements. The second electrode assemblies include second electrodes and second strip elements. At least one terminal assembly includes a base part and a counter-element, which base part includes a first contact face and the counter-element includes a second contact face. The counter-element resiliently engages with at least one groove-like recess of the base part in such a way that a first force is applied to the first contact face and the second contact fact, pushing them towards one another. The first strip elements or second strip elements are arranged between the first contact face and the second contact face.

Abstract: A battery cell includes a housing, an electrode stack assembly, at least one terminal assembly, and at least two counter-elements associated with the terminal assembly. The electrode stack assembly is arranged in the housing and includes first electrode assemblies and second electrode assemblies. The terminal assembly includes a base part, two terminal elements, and at least two arms, which arms respectively extend between the base part and one of the terminal elements and are configured so as to apply a first force on the terminal elements in the direction of the associated counter-elements. First strip elements or second strip elements are arranged between at least one of the terminal elements and at least one of the counter-elements. The base part forms a connecting element for electrically contacting the battery cell, which connecting element can be contacted from the outside, and which base part is electrically connected to the electrodes.

Abstract: A fire protection device (1) is provided for an at least partially electrically operated motor vehicle for detecting a fire caused by a battery device (2) of the vehicle. The fire protection device (1) includes a fire sensor (4) that is connected operatively to a monitoring system (3). The fire sensor (4) has a monitoring current conductor (14) that is suitable and configured for being interrupted by fire-induced destruction in the event of a fire. The monitoring system (3) is suitable and configured for detecting the fire by the interrupted monitoring current conductor (14).
