A method for supporting a battery housing when a battery module is inserted. A support device includes a support for supporting the battery housing. Here, the support has several mutually movable pin elements for setting down the battery housing. A negative shape corresponding to a shape of a base bottom side of a housing base of the battery housing by the pin elements is set on the basis of a selective displacement of the support along a predetermined translational direction of movement in that each pin element is displaced from a respective starting position to a respective end position when it reaches the base bottom side and locked at the respective end position by a locking unit. After the negative shape has been set, the support is displaced by a defined offset distance opposite to the direction of movement.

A method for connecting an energy storage module to a module support, in particular a cooling element, The energy storage module is fastened on the module support by multiple connecting screws, which are each screwed into threaded bores provided on the module support. A gap is provided between the bottom of the energy storage module and the bottom of the module support, into which a thermally-conductive compound is introduced, which is distributed to fill the gap due to a reduction of the gap width when the energy storage module is screwed down.

A method for producing a traction battery of a motor vehicle. A battery housing of the traction battery has a receiving compartment for receiving a cell module. It is thus provided that the receiving compartment is delimited by a bottom and walls adjoining said bottom, A topography of the bottom is recorded by measuring technology, a thermal-conductor amount determined by the topography is applied locally to the bottom, whereupon the cell module is inserted into the receiving compartment.

A method for producing a traction battery of a motor vehicle. A battery housing of the traction battery has a receptacle for receiving a cell module. It is provided that support surfaces for supporting the cell module spaced apart from a bottom of the battery housing are formed on walls of the battery housing delimiting the receptacle compartment, and that a distance between the support surfaces and the base is measured, an amount of heat conducting calculated from the distance is applied to the bottom, and then the cell module is inserted into the receptacle compartment supported on the support surfaces.

A method for assembling a traction battery for an electrically operated vehicle, in which at least one battery module is inserted into a battery housing in a module setting process, with the formation of an air gap between the battery module and a housing base of the battery housing, which is filled with a highly viscous thermal paste, which builds up a viscosity force due to internal friction when it is distributed in the air gap, which acts on the housing base until the thermal paste is distributed in the air gap by the flow of material and the accompanying reduction in the viscosity force. The housing base is supported on its housing base lower side by a counter holder in order to limit a deflection of the housing base due to the viscosity force of the thermal paste.

A battery device and a method for producing a battery device for a motor vehicle. In said method, a cooling base element and a battery module are provided, and the battery module is mounted on the cooling base element, forming at least one gap between a battery module region and a cooling base region. A filling device is then coupled to at least one filling opening of at least one filling tube, with the at least one filling tube extending into the at least one gap, and a heat conducting medium is introduced from the filling device through the filling tube into the at least one gap.

A battery housing to hold a battery module, wherein the battery housing includes a housing bottom, wherein the housing bottom comprises at least one injection opening, through which a thermally conductive material can be injected by means of an injection device into the battery housing in a first direction through the housing bottom, wherein the battery housing includes an elastically compressible sealing element, which is arranged in the area of the at least one injection opening, and is designed to close the at least one injection opening, wherein the sealing element is designed to open up the injection opening by elastic compression of the sealing element as of a predetermined injection force (Fi) acting in the first direction during the injecting of the thermally conductive material, and to close the injection opening once more by expanding of the sealing element in absence of the injection force (Fi).

Battery housing to hold a battery module, battery module arrangement, motor vehicle and method for incorporating a thermally conductive element in a battery housing

A method and production equipment for producing a battery and a motor vehicle with such a battery. In the method, at least one battery module is positioned and attached in a provided battery housing such that it covers at least one gap provided in a housing base of the battery housing. The housing base is then bent, outward along the gap, whereby a cavity is enlarged between the battery module and the housing base. A viscous heat-conductive filler is then supplied into the cavity through the gap. Subsequently, the bending of the housing base is reversed by pushing the housing base back in the direction of the battery module.

A system for producing a battery arrangement with at least one battery module and a battery housing. The at least one battery module comprises at least one supply channel which extends in a designated introduction direction through the at least one battery module. The at least one battery module is to be introduced in the introduction direction into the battery housing, positioned in an end position provided for the battery module and firmly connected in this end position to the battery housing. Between a bottom of the at least one battery module and a bottom of the battery housing, at least one cavity is provided, which is to be connected to the at least one supply channel. A filler material is to be filled into the at least one cavity through the at least one supply channel.
