A battery module (10) has a first and second partial modules (12, 16) with first and second battery cells (14, 18) respectively. A cooling medium for cooling the first battery cells (14) is in a first volume that is bounded by a first partial housing (28) and can flow through the first partial module (12), and a cooling medium for cooling the second battery cells (18) in a second volume bounded by a second partial housing (34) can flow through the second partial module (16). The first partial housing (28) has a first tubular flange (36) projecting into a first intermediate space (24) between the first battery cells (14), and the second partial housing (34) has a second tubular flange (38) projecting into a second intermediate space (30) between the second battery cells (18). The first and second volumes are connected via the first and second tubular flanges (36, 38).

1. A battery module for providing purely electric drive of a motor vehicle, the battery module comprising: a first partial module having a first partial housing with a first volume surrounded by at least one first sidewall, a plurality of first battery cells accommodated in the first volume, each of the plurality of first battery cells extending in an axial direction and parallel to each other, and a first intermediate space between the plurality of first battery cells and the at least one first side wall, and at least one first tubular flange protruding into the first intermediate space to accommodate a flow of a cooling medium from the at least one tubular flange and through the first partial module for cooling the plurality of first battery cells; anda second partial module connected to the first partial module, the second partial module having a second partial housing with a second volume surrounded by at least one second sidewall, a plurality of second battery cells accommodated in the second volume, each of the plurality of second battery cells arranged coaxially with one of the plurality of first battery cells, and a second intermediate space between the plurality of second of battery cells and the at least one second side wall, and at least one second tubular flange protruding into the second intermediate space, the at least one second tubular flange being in fluidic communication with the at least one first tubular flange to accommodate a flow of the cooling medium from the at least one first tubular flange to the at least one second tubular flange and into the second partial module for cooling the second battery cells. 2. The battery module of claim 1, wherein the first partial module has an inlet for feeding in the cooling medium, and the second partial module has an outlet for discharging the cooling medium, the inlet being a tubular inlet flange projecting on a side pointing away from the second partial housing into the first intermediate space formed between the plurality of first battery cells, and the outlet being a tubular outlet flange projecting, on a side pointing away from the first partial housing into the second intermediate space formed between the plurality of second battery cells. 3. The battery module of claim 2, wherein the first partial housing has a first attachment projection adjacent to the first tubular flange and pointing away from the first volume for attachment to the second partial housing and the second partial housing has a second attachment projection adjacent to the second tubular flange and pointing away from the second volume for attachment to the first partial housing. 4. The battery module of claim 3, further comprising a seal between the first tubular flange the second tubular flange for achieving a fluid-tight connection. 5. The battery module of claim 1, wherein each of the plurality of first battery cells has a first pole projecting from the first volume and pointing toward the second partial module, and the second battery cell has a second pole projecting from the second volume and pointing toward the first partial module, wherein the first and second poles are in an intermediate volume that is sealed with respect to the cooling medium. 6. The battery module of claim 1, wherein the first tubular flange and the second tubular flange form a reversal collector pipe that spans a distance between the first volume and second volume. 7. The battery module of claim 1, wherein the first volume forms a first collector volume in a direction pointing away from the second partial module for diverting the cooling medium into the first tubular flange, and the second volume forms a second collector volume in a direction pointing away from the first partial module for diverting the cooling medium from the second tubular flange. 8. The battery module of claim 1, wherein the second partial module is symmetrical with respect to the first partial module. 9. The battery module of claim 1, wherein the plurality of first battery cells are arranged in at least first and second rows next to one another and the at least one first tubular flange is arranged on the first sidewall of the first partial housing at ends of the second row, and the plurality of second battery cells are arranged in at least first and second rows next to one another and the at least one second tubular flange is arranged on the second sidewall of the second partial housing at ends of the second row.
