Description

[0014] The invention will now be explained in more detail. The figures show the following:

[0015] FIG. 1 a schematic representation of a motor vehicle provided with a battery according to the invention;

[0016] FIG. 2 a schematic representation of the battery in a sectional view;

[0017] FIG. 3 a schematic representation of the batter of FIG. 2 in a cross-sectional view; and

[0018] FIG. 4 a schematic representation of the battery of FIG. 2 in a cross-sectional view.

[0019] The embodiments discussed below are preferred embodiment of the invention. However, in these embodiments, the components described in the embodiments represent in each case individual features of the invention that should be considered as being independent of each other which further modify the invention as component parts of the invention in other combinations than those that are shown. Furthermore, the embodiments described can be also further complemented by other, already described features of the invention.

[0020] FIG. 1 shows a schematic representation of a motor vehicle 10, which is preferably designed as an automobile, in particular as a passenger car. A battery 18 is in this case arranged in an underfloor 12 of the motor vehicle 10. Passage elements 28, shown here only schematically, extend through the battery 18 of the motor vehicle 10, from the motor vehicle rear 14 to the front 16 of the motor vehicle. The passage element 28 can be designed for example as a brake line. The brake line can be at the same time connected to a first brake circuit and to a second brake circuit (not shown in FIG. 1) of the motor vehicle. The first brake circuit can be in this case arranged at the front 16 of the motor vehicle and the second brake circuit can be arranged at the rear 14 of the motor vehicle. In order to connect both brake circuits, the brake line, illustrated by the dashed line in FIG. 1, can be routed through the battery 18. The passage element 28 can be also a cooling circuit and/or a signal line. Various other types of the passage element 28 can be also routed through the battery 18.

[0021] FIG. 2 shows again schematically the battery 18, which can be designed in particular as a high-voltage battery. The battery 18 in this case comprises a housing 20, whose walls delimit a housing space 22. The battery cells 24 are placed in the housing space 22 in a predetermined arrangement. Between the battery cells 24 placed in the housing space 22 is provided an intermediate space 26. A passage element 28 extends through this intermediate space 26 from a first wall 30 of the walls of the housing 30 to a second wall 32 of the walls of the housing located on the opposite side. In other words, the passage element 28 is routed through the battery 18 where there is space available based on the construction design.

[0022] Furthermore, the passage element 28 can be also subdivided within the battery 18 into a first line part and a second line part (not shown in FIG. 2), wherein the first and the second line parts are mutually connected to one another with a connecting element (not shown in FIG. 2). The passage element 28 can be also composed of several line parts. The connecting element can in this case be designed as a T-shaped piece or as an angle piece. As a result, the passage element 28 can be routed through the housing 20 of the battery 18 between the battery cells 24 not only in a straight line (as shown in FIG. 2), but it can be also for example adapted in a flexible manner. For example, the passage element 28 can be inserted between the battery cells 24 in a step-like manner. Several line parts of the passage element 28 can thus be connected with a connecting element in order to match it to the usable free space between the battery cells 24.

[0023] As one can see from FIG. 2, the passage element cuts or penetrates through the first wall 30 and through the wall 32 of the housing 20 on the opposite side. A connecting element 34 is arranged on an outer side of the first wall 30 and of the second wall 32, which is coupled to the passage element 28. In other words, the passage element 28 ends in the vicinity of the housing 20 of the battery 18 with a connecting element 34, through which the passage element 28 is connected fluidically and/or electrically and/or with a line element for technical signals and/or with a circuit of the motor vehicle 10 in which is circulated a fluid. The passage element 28 can thus be coupled in this manner in a particularly simple manner with an electrical and or technical signal line element and/or with a circuit of the motor vehicle 10.

[0024] FIGS. 3 and 4 illustrate a schematic cross-section of the battery 18 of FIG. 2. The battery cells 24 are in this case arranged next to each other at a predetermined distance to each other. Between the battery cells 24 is provided an intermediate space 26 at a predetermined distance, through which is placed the passage element 28 on the bottom of the housing 20 of the battery 18. In FIG. 4, however, the passage elements 28 are arranged above the battery cells 24. As illustrated in FIG. 3 and FIG. 4, the passage element 28 is not bound to a predetermined location in the intermediate space 26, but instead it can be arranged depending on the dimensioning of the battery 18 at different locations in the housing 20 in each intermediate space 26.

[0025] The overall result is a battery system that is provided with integrated brake lines. These lines are routed through a battery housing. For this purpose, the usable free space locations inside the battery housing are used in order to route the line through them. To make the assembly of the battery even more independent of these lines, coupling location are arranged before and after the battery.
