Subunit of a battery module, battery module comprising such a subunit and method for producing same

A method for producing a subunit (1) of a battery module (2), wherein, in a first method step, a first receiving element (3) and a second receiving element (4) are provided, and, in a second method step, at least one battery cell stack (5) or at least one battery cell (6) is arranged between the first receiving element (3) and the second receiving element (4), and, in a third method step, the first receiving element (3) and the second receiving element (4) are connected to each other in such a manner that a first receiving space (7) is formed, in which the at least one battery cell stack (5) or the at least one battery cell (6) is accommodated, and a second receiving space (8) is formed, which is configured for receiving a temperature-control fluid (9), wherein the first receiving space (7) and the second receiving space (8) are separated from each other.

A battery module comprising first and second subunits (16, 17), the first and second subunits each comprising

• a first receiving element (3) and a second receiving element (4) which are connected to each other, forming at least one first receiving space (7) and at least one second receiving space (8), wherein the first receiving space (7) and the second receiving space (8) are separated from each other, and at least one battery cell stack (5) or at least one battery cell (6) is arranged in the first receiving space (7), and the second receiving space (8) is configured for receiving a temperature-control fluid (9),
• wherein a first first section (161) of the first receiving element (31) is arranged directly adjacent to a second second section (172) of the second receiving element (42), wherein the first first section bounds the first receiving space (71) of the first subunit (16) and the second second section bounds the second receiving space (82) of the second subunit (17).
