COOLING SYSTEM FOR A BATTERY MODULE

The invention relates to a cooling system (104) for a battery module (100), comprising: cooling plates (112), each having at least one internal cooling channel (122) and configured to be arranged on side surfaces of the battery module (100) extending in a longitudinal direction (L); end plates (114) configured to be arranged on end faces of the battery module (100) extending in a width direction (W), each of the end plates (114) comprising connecting tubes (118) configured to be sealably connectable with the internal cooling channel (122) of each cooling plate (112), to form a cooling cycle; a first end plate (116) comprising a connecting cavity (117) fluidly connecting the cooling channels (122) of the opposing cooling plates (112) with each other, a second end plate (138) comprising a first cavity (139) and a second cavity (141), both being fluidly separated from each other, each cavity being fluidly connected to the cooling channels (122) of one of the cooling plates (112), the second end plate (138) further comprising an input port (142) configured as an inlet for a cooling fluid and an output port (144) as an outlet for the cooling fluid; and the input port (142) being provided in the first cavity (139) and the output port (144) being provided in the second cavity (141). Further, the invention relates to a battery module (100) including such cooling system (104).
