Abstract: The technology disclosed here relates to a pressure container system. The pressure container system includes a plurality of pressure containers for storing fuel and at least one load-distributing base layer. The load-distributing base layer is advantageously arranged between a lower base plate and the plurality of pressure containers. The load-distributing base layer is designed such that forces F, which act locally on the lower base plate and which act on the lower base plate substantially in the direction of the vehicle vertical axis Z, can be distributed to the plurality of pressure containers.

Abstract: A battery module stores electrical energy. The battery module includes one or more battery cells disposed between two compression plates so as to be next to one another along a transverse axis of the battery module. The battery module is configured such that a spacing between the two compression plates is variable within a spacing range so that a variation in a spatial extent of the one or more battery cells exists along the transverse axis. The two compression plates apply a compressive force to the one or more battery cells within the entire spacing range.

Abstract: A method is provided for arranging a high-voltage accumulator having a plurality of battery modules on a support structure of a motor vehicle, in which the battery modules are arranged and fastened on a base plate, and the base plate is fastened on a bottom plate of the support structure of the motor vehicle, as a result of which the base plate and the bottom plate provide an accumulator housing which delimits an accumulator interior in which the battery modules are accommodated. At least one connection field is mechanically connected to the support structure. The connection field is able to electrically and/or fluidically connect the high-voltage accumulator to the motor vehicle.

Abstract: A battery cell pack includes a multiplicity of battery cells arranged next to one another. A multiplicity of frame elements corresponds geometrically to the battery cells. A battery cell is positionally fixed by means of two of the frame elements directly adjacent to each other by the corresponding battery cell being inserted into a battery cell space formed by the two directly adjacent frame elements. An intermediate layer is arranged directly between the respective battery cell and the frame elements, such that the respective battery cell is held in the battery cell space via the intermediate layer. The intermediate layer is elastically compressible, without destruction, by a swelling of the directly adjoining battery cell to a swelling extent, as a result of which, despite the swelling of the corresponding battery cell, a size of the battery cell space and therefore external dimensions of the battery cell pack remain constant.

Abstract: An underbody module for a motor vehicle includes a left side element and a right side element, wherein the side elements extend in a longitudinal direction and are connected on the end sides by transverse elements, as a result of which an upper contact surface and a lower contact surface are formed. A floor element is arranged on the upper contact surface. A cover element is arranged or can be arranged on the lower contact surface, as a result of which an arrangement space is formed or can be formed between the floor element and the cover element, wherein the floor element is arranged in a gas-tight manner.
