Embodiment Construction

[0063] figure 1 Firstly, a cell module 1 is shown, which has a plurality of so-called module boxes 3 combined in a module housing 2 . according to figure 2 and 3 Each module box 3 has a frame element 4 in or at which plate-shaped battery cells 5 , in particular pouch-shaped cells, and a cooling device 6 are fastened. According to this embodiment, the battery cells 5 and the cooling plate 7 of the cooling device 6 are in large-area contact with an interposed film 8 acting as an insulator, in particular a polyimide film, which can be difficult to Ignite and are high temperature resistant and have a high electrical breakdown field strength. On the other side of the battery cell 5 there is provided a plate-shaped foam element 9 which contacts the adjacent module box in the form of a compound with the other module box 3 within the cell module 1 3 or its foam element 9 or cooling plate 7 (not shown in a drawn manner). The mentioned foam element 9 serves to absorb any pending e...

Abstract

The invention relates to a cooling device for at least one battery cell, a cell module and a method for producing a cooling plate of the cooling device. The invention relates to a cooling device (6) for at least one battery cell (5), in particular a pouch cell, comprising a cooling plate (7) which is formed by a plate core (15) and two cover layers (16, 17), said plate core (15) having at least one elongated recess (18a-17). D) which forms a channel structure with the aforementioned cover layer (16, 17) for the passage of a cooling fluid through the channel structure in accordance with a defined function of the channel structure, said channel structure having a fluid inlet and a fluid return (20a-1), which channel structure has a fluid inlet and a fluid return (20a-d; 21a-d).

Description

technical field [0001] The invention relates to a cooling device for at least one battery cell, in particular a pouch cell (sometimes called a pouch cell), according to the combination of features of patent claim 1 of the invention. According to claim 9 of the present invention, the invention also relates to a cell module with at least one such cooling device. According to claim 10 of the invention, the invention also relates to a method for producing a cooling plate of the cooling device mentioned. Background technique [0002] It is generally known to combine electrochemical cells or battery cells in a module housing to form a so-called cell module and to electrically connect the battery cells to one another by means of electrical connectors, whereby The negative and positive electrode connections of the relevant cell modules are produced. The electrical connection of a large number of such unit cell modules enables the production of HV battery systems or HV battery pack...
