Abstract: A support structure (7) for a number of battery modules (2), having: a plurality of support elements (7a, 7b), which support elements (7a, 7b) are disposed so as to be mutually spaced apart and therebetween configure a number of compartments (7c), which compartments (7c) are specified to receive in each case one battery module (2); which support structure (7) is distinguished by the fact that at least a number of the support elements (7a) are configured as fluid line elements or comprise fluid line elements, which fluid line elements extend into the respective region of the compartments (7c), and by way of which fluid line elements a temperature-control fluid for the battery modules (2) is able to be supplied into the region of the compartments (7c) and is able to be discharged again from there.

Abstract: A plug-type connection (1) having an inner pipe (2) and an outer pipe (3), which outer pipe (3) is plugged with one of end thereof onto one end of the inner pipe (2). The plug-type connection (1) has a spring element (4) arranged on the outside of the inner pipe (2) in the region of the end thereof, and the outer pipe (3) has a first widened portion (3a) at that end, in a region of which the outer pipe (3) is spaced apart (A) from the inner pipe (2) and engages over the spring element (4). The outer pipe (3) has an engagement structure (3b) in the region of the first widened portion (3a), with which engagement structure (3b) the spring element (4) is in engagement.

Abstract: A fluid distribution system (1) having a main distribution line (2) and a number of branch lines (7), which branch lines (7) branch off in each case from the main line (2). A throttle device (8) is arranged in at least one branch line (7), and the throttle device (8) is formed by at least a local deformation of the relevant branch line (7). A method for producing such a fluid distribution system (1) is likewise provided.

Abstract: A battery cell connection element (4) including a main body (44) formed as a fluid line element made of an electrically conductive material with a longitudinal axis (L). The main body (44) is preferably closed at both ends (4a, 4b), in particular in a fluid-tight manner, and has a peripherally, substantially closed casing wall, in which at least two through-openings (4da, 4ea), preferably punch-outs, are arranged on the same side of the main body (44), with these through-openings (4da, 4ea) being arranged adjacent to one another and offset in the direction of the longitudinal axis (L), in order to be able to connect the battery cell connection element (4) to cell arresters (3) of battery cells of a battery cell assembly via the through-openings (4da, 4ea).

Abstract: A method for fluidically connecting functional modules that are temperature-controlled by a fluid, preferably battery modules, including a) providing the functional modules with at least one line port for directing the fluid in and/or out, at least two functional modules being arranged at a mutual spacing so the line ports are substantially exactly opposite each other and aligned along a first axis and open into a region between the modules, c) incorporating a preassembled connection assembly in the region, the connection assembly having fluid line(s) for feeding and/or discharging the fluid, and at least two fluidic connector pieces which branch off from the fluid line(s) such that the connector pieces are aligned with the line ports along the first axis, and d) modifying a spacing between the connector pieces and/or a length thereof along the first axis such that the connector pieces each fluidically contact one of the line ports.
