This application claims priority to German Patent Application No.: 10 2020 121 882.6, filed Aug. 20, 2020, the content of such application being incorporated by reference herein in its entirety.
The present invention relates to a high-voltage battery for a motor vehicle. The present invention furthermore relates to a corresponding method for producing a high-voltage battery, and to a motor vehicle having a battery of this type.
DE 102017208617 A1 and EP 3667759 A1, which are each incorporated by reference herein, each disclose a cooling line, the inner part of which forms a flexible tube for compensating for tolerances.
DE 102017006517 A1, which is incorporated by reference herein, relates to a cooling connection, fastened in a releasable manner via an adapter, on the housing cover of a battery. For this purpose, the battery cover has a cylindrical opening, into which a fluid-guiding connection plug is plugged.
In a different connection, DE 102014203943 A1, which is incorporated by reference herein, proposes a screwed connection flange.
Described herein is a high-voltage battery for a motor vehicle, a corresponding method for producing a high-voltage battery and a motor vehicle having a battery of this type.
An advantage of this battery is its coolant connection, which does not hinder the assembly and, in particular, the welding of the battery cover.
The high-voltage battery can thus contain a coolant line that is flexible at least in sections for the purpose of tolerance compensation.
The coolant connection can also comprise a flat seal for ensuring the seal tightness.
Finally, the coolant connection can comprise a connection flange with threaded sleeves that are accessible from outside of the high-voltage battery and that likewise contribute to ensuring the seal tightness and fixing the coolant connection.
One exemplary embodiment of the invention is illustrated in the drawings and will be described in more detail below.
Said inner part of the coolant connection (11—
The coolant line (17)—at least in the section thereof facing the coolant connection (11)—is welded on the inner side of the cover wall (16) to the connection flange (12) and is of flexible design in order to be able to compensate for any tolerances of the components of the high-voltage battery (10). A flat seal (18) is also inserted between the connection flange (12) and the cover wall (16) and seals the high-voltage battery (10) from the surroundings thereof.
These structural characteristics make it possible for the connection flange (12) to be placed against the cover wall (16) from inside—before or after the coolant line (17) has been welded—in an intuitive manner in such a way that the threaded sleeves (13) project toward the outside through the cover wall (16) and for the securing rings (15) to be able to be slid onto the threaded sleeves (13) from the outside until they engage into the grooves thereof. In this state, the cover wall (16) can be provided with a circumferential weld seam (14) in an unhindered manner in order to seal off the high-voltage battery (10).
