a battery module disposed within the battery housing; and a cooling device for the battery module, the cooling device disposed within the battery housing and comprising: a cooling element configured to extend from a first side of the cooling element to an opposite second side of the cooling element, the first side facing the battery module; at least one spring element arranged on the second side of the cooling element and configured to exert a pressing force on the second side of the cooling element in a tensioned state to press the cooling element against the battery module; and at least one tensioning device coupled to the spring element, wherein a contact region of the tensioning device extends beyond the second side of the cooling element when the spring element is in a relaxed state, wherein the tensioning device has a first end connected to and extending from an end region of the spring element and a second end abutting against the battery module, wherein the cooling element has one or more through holes, and wherein the tensioning device extends through the one or more through holes. ### Claim 2 (depends on 1) the cooling device according to claim 1, wherein the tensioning device is configured to increase a spring tension of the spring element when the contact region of the tensioning device is moved in the direction of the second side. ### Claim 3 (depends on 1) The cooling device according to claim 1, wherein the contact region is configured to abut against the battery module and is configured to be pressed by the battery module toward the second side when the battery module is made to approach the first side of the cooling element. ### Claim 4 (depends on 1) The cooling device according to claim 1, wherein the spring element has at least one first contact region to the second side of the cooling element and at least one second contact region to a battery housing in which the cooling element is arranged. ### Claim 5 A cooling device for a battery module, the cooling device comprising: a cooling element configured to extend from a first side of the cooling element to an opposite second side of the cooling element, the first side facing the battery module; at least one spring element arranged on the second side of the cooling element and configured to exert a pressing force on the second side of the cooling element in a tensioned state; and at least one tensioning device coupled to the spring element, wherein a contact region of the tensioning device extends beyond the second side of the cooling element when the spring element is in a relaxed state, wherein the cooling element has at least one through hole or a plurality of through holes, and wherein the tensioning device extends through at least one through hole or the cooling device has a plurality of tensioning devices corresponding to the plurality of through holes. ### Claim 6 (depends on 5) the cooling device according to claim 5, further comprising a plurality of spring elements corresponding to the plurality of through holes. ### Claim 7 (depends on 5) the cooling device according to claim 5, wherein the at least one spring element extends over an area of the cooling element, which comprises a number or all of the plurality of through holes. ### Claim 8 (depends on 1) The battery according to claim 1, wherein the cooling device has a plurality of tensioning devices corresponding to the one or more through holes. ### Claim 9 (depends on 1) The battery device according to claim 1, further comprising a plurality of spring elements corresponding to the one or more through holes. ### Claim 10 (depends on 1) The battery device according to claim 1, wherein the at least one spring element extends over one of the through holes.
