Abstract: A traction battery with a battery housing and a plurality of battery cells arranged in the battery housing. At least one flame-retardant plate is arranged in the battery housing and separates two housing chambers from one another. A plate receiving structure with at least one groove pair including two opposite grooves is present in the battery housing. The at least one flame-retardant plate is held in the battery housing by the plate receiving structure. Also described is a method for producing such a traction battery.

Abstract: A traction battery of an electrically or semi-electrically driven vehicle includes one or more cooperating battery modules, in which a respective plurality of chambers are provided for receiving one or more cell stacks from a respective plurality of battery cells. The battery module is configured as a hollow profile, which includes the respective plurality of chambers separated from one another by intermediate walls and running parallel in a longitudinal direction of the hollow profile, into which chambers the cell stacks can be inserted. The hollow profile is sealed at both ends with a respective lid spanning end-side opening cross-sections of all chambers. End sections of the intermediate walls reaching to the opening cross-section are sealed with a separate sealing component against an inside of the lid.

Abstract: A modular system has at least a first module (A, B) and a second module (D, E, H). The modules are configured such that a first apparatus having the first and second modules (A, B, D, E, H) is configured as a first control unit (1) for a first traction battery of a first motor vehicle. The first module (A, B) is configured for first functions of the first control unit (1) and the second module (D, E, H) is configured for second functions of the first control unit (1). The first module (A, B) also is configured such that a second apparatus having the first module (A, B) without the second module (D, E, H) is configured as the second control unit (2, 3) for a second traction battery of a second motor vehicle, with the second functions being absent from the second control unit (2, 3).

Abstract: A traction battery vehicle floor has a plurality of self-supporting battery modules arranged in a horizontal plane (X,Y). The battery modules are fastened in a supporting manner directly to two lateral vehicle floor longitudinal supports. Adjacent to the frontmost and/or rearmost battery module, an electrical battery control module having a self-supporting battery control module housing is arranged in the battery module horizontal plane (X, Y). The two transverse ends of the battery control module housing are each structurally connected to the corresponding longitudinal support in a supporting manner.

Abstract: A battery arrangement for a motor vehicle includes a battery housing and battery cells. The battery housing has a wall which runs around at least on four sides and encloses an interior of the battery housing. The battery housing has a separating web which divides the interior into two chambers. The battery housing has a preferred direction in which the encircling wall and the separating web extend. Battery cells are arranged in the two chambers. The battery housing is composed of one profile element that is T-shaped in section and two profile elements that are L-shaped in section, so that the profile elements form the encircling wall and the separating web.

Abstract: A method for interconnecting cell stacks of a battery module in a battery. In the battery module, the cell stacks are arranged in a battery module housing. In each case two cell stacks are arranged next to one another and form a cell stack group, and the two cell stack groups are arranged behind one another. The two cell stacks of the first cell stack group are inserted into the battery module housing. The two cell stacks of the first cell stack group are electrically interconnected via at least one opening arranged in a wall of the battery module housing. The two cell stacks of the second cell stack group are inserted into the battery module housing. Electrically interconnecting the two cell stacks of the second cell stack group to each one of the two cell stacks of the first cell stack group.
