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: 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 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 modular motor vehicle architecture is provided for motor vehicles of different motor vehicle types, in each case having at least one drive machine and at least one energy storage unit paired with the at least one drive machine. The at least one energy storage unit is received in a modularly designed underfloor energy storage unit assembly that has a plurality of energy storage unit modules, at least one outer dimension of which is standardized. Each vehicle type is paired with one underfloor energy storage unit assembly from a plurality of standardized underfloor energy storage unit assemblies. And, each underfloor energy storage unit assembly has a plurality of unit module installation areas, a longitudinal dimension of which extending in the longitudinal direction of the motor vehicle is standardized and each of which is designed to receive at least one respective standardized energy storage unit module.

Abstract: A motor vehicle includes at least one pressure vessel for storing fuel, and at least one holder for holding the pressure vessel. When installed, the holder encloses one end of the pressure vessel. The holder has a hard shell and an inner layer, wherein at least regions of the inner layer, when installed, are arranged between the hard shell and the connecting element. The hard shell has a higher rigidity than the inner layer.

Abstract: A group of motor vehicles contains at least vehicles of two different vehicle types of the following vehicle types: a battery drive vehicle with only one electric motor drive, a hybrid drive vehicle with an electric motor drive and an internal combustion engine drive, a fuel cell drive vehicle with a fuel cell drive, and an internal combustion engine drive vehicle with only one internal combustion engine drive. All of the vehicle types of the group of motor vehicles have a base assembly with a left-side sill structure, a right-side sill structure, an upper base, a lower base, and a central tunnel structure.

Abstract: A battery cell module for an electrically drivable motor vehicle has a bottom side and a top side. The battery cell module includes a support structure for battery cells and battery cells supported by the support structure. The battery cell module has at least one pressure element, which can be loaded on the bottom side and relocated relative to the support structure in order to transfer a load, in the case of limited load input into the support structure, from the bottom side to the top side. An electrically drivable motor vehicle has a bottom-side structure and a top-side structure. The bottom-side structure and the top-side structure delimit a receiving chamber for battery cell modules. The motor vehicle has at least one such battery cell module. The pressure element is supportable on the bottom-side structure and on the top-side structure in order to transfer a load, in the case of limited load input into the support structure, from the bottom side to the top side.

Abstract: A method for integrating a high-voltage accumulator having at least one accumulator module into a support structure of a motor vehicle, wherein the following is performed: providing a housing part, which has a base plate and a frame-like edge extending around the base plate; arranging the at least one accumulator module on the housing part and/or on the support structure; arranging the edge of the housing part below and on a frame structure formed of supports of the support structure; and fastening the housing part to the support structure. An accumulator housing for the at least one accumulator module is thus formed. A housing interior of the accumulator housing is delimited by a bottom part of the support structure, which bottom part covers the frame structure toward a passenger compartment of the motor vehicle, and by the housing part and the frame structure.
