Abstract: A battery cell with an internal cooling element includes an interior in which electrochemically active components are arranged. The interior has an outer wall on each of at least two sides, which are connected to each other by an inner wall. The internal cooling element is arranged in the inner wall. Also described is a battery module with at least two of the battery cells.

Abstract: A battery cell including a cell housing having a first side wall and a second side wall which is parallel to the first side wall. A projecting spacer structure which is formed by the respective side wall is provided on an outer side of the first side wall and/or on an outer side of the second side wall. A liquid-cooled battery includes a plurality of battery cells, which are stacked such that the second side wall of a first battery cell abuts the first side wall of an adjacent second battery cell and a spacer structure of the second side wall of the first battery cell and/or a spacer structure of the first side wall of the second battery cell form at least one respective intermediate space between two adjacent battery cells which is configured such that a cooling liquid (K) flows through the intermediate space during operation.

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 battery system for an electrically or semi-electrically driven vehicle, in particular for a passenger car. The battery system includes at least two battery modules, each having a module housing and a plurality of battery cells arranged in the module housing. The battery system includes a cooling system for cooling the battery cells. The battery system includes a busbar, wherein the at least two battery modules are connected to one another by the busbar. The battery system includes a busbar housing configured outside of the module housing, wherein the busbar is arranged in the busbar housing and is thermally coupled to the busbar housing. The busbar housing is thermally coupled, at least in portions, to at least one of the battery modules, preferably to the module housing of the at least one battery module.

Abstract: A motor vehicle traction battery arrangement includes two cooling plates respectively disposed in a horizontal plane and a high-voltage battery module. The lower and upper horizontal walls of which are cooled directly by the cooling plates and which encases a plurality of identical rectangular battery cells in a rigid battery module housing. The battery cells are all configured such that they are plate-like and elongated, are parallel to one another in vertical planes (y,z) and each includes two small-area vertical end walls, two large-area vertical side walls and two medium-area horizontal walls. On its end face, each battery cell includes an anodic connecting element and a cathodic connecting element. At least two similar cell stacks including a same plurality of battery cells are provided, and are stacked such that their battery cell side walls adjoin one another. The battery cell horizontal walls directly adjoin a cooled battery module horizontal wall.
