1. A system comprising:
a plurality of battery modules (10; 80), wherein each battery module comprises a plurality of battery cells (11; 81) and two side plates (12), each side plate having a protruding lower edge (14), wherein the battery cells are stacked with a bottom surface (15) supported by the protruding lower edge (14) of the two side plates (12);
a cold plate (20; 30; 40) for cooling the plurality of battery modules;
wherein:
the cold plate comprises:
a base plate (21; 31; 41) provided with cooling channels, wherein the base plate (21; 31; 41) is thermally connected to the bottom surface (15) of the battery cells (11; 81) in each battery module (10; 80);
an inlet port (24) for feeding cooling media via the cooling channels to an outlet port (26); and
at least one cut-out (22, 23; 32; 42) configured to house one of the protruding lower edges (14) of the side plates (12),
the cooling channels comprise a first cooling loop (28; 38; 68) and a second cooling loop (29; 39; 69),
the cooling channels comprise an inlet manifold (25) and an outlet manifold (27) to provide cooling media from the inlet port (24) to the outlet port (26) via the first cooling loop (28; 38; 68) and the second cooling loop (29; 39; 69), and
the at least one cut-out (22, 23; 32; 42) is arranged between the first cooling loop (28, 38) and the second cooling loop (29; 39).
