• 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.
