A fluid distribution system (4) for a battery module arrangement (1) comprising a number of battery modules (2.1-2.6), in which the battery modules (2.1-2.6) each have at least one first fluid connector (F1) and each have at least one second fluid connector (F2), the fluid distribution system (4) comprises:
- a first main line element (6) from which there branches off at least one first branch line portion (7.1);
- a second main line element (6′) from which there branches off at least one second branch line portion (7.1′);
- a first connection element (8.1) detachably connected or connectable to the at least one first branch line portion (7.1) of the first main line element (6);
- a second connection element (8.2) detachably connected or connectable to the at least one second branch line portion (7.1′) of the second main line element (6′);
- the first connection element (8.1) has a first curvature that matches a routing direction of the first branch line portion (7.1) to a routing direction of the first fluid connector (F1);
- and
- the second connection element (8.2) has a second curvature that matches a routing direction of the second branch line portion (7.1′) to a routing direction of the second fluid connector (F2).
