1. A battery module comprising:
a first module;
a second module adjacent to the first module in a first direction and coupled to the first module,
wherein each of the first module and the second module comprises:
a plurality of cell stacks;
a module housing; and
a plurality of receiving parts in the module housing, the plurality of receiving
parts being configured to accommodate the plurality of cell stacks; and a coupling part coupling the module housing of the first module to the module housing of the second module,
wherein each of the plurality of receiving parts comprises a fixed wall, wherein the module housing of the first module is coupled to the module housing of the second module in a first direction,
wherein a cooling channel for a coolant to flow to cool the plurality of receiving parts and the plurality of cell stacks is below a floor surface of the module housing, wherein the battery module further comprises a cooling plate coupled to the floor surface of the module housing, wherein the cooling channel is in the cooling plate, and a coolant line connected to the cooling channel of the module housing of each of the first and second modules,
wherein the coolant line extends in the first direction and comprises a plurality of port connection holes spaced from each other along a length direction of the coolant line and coupled to the cooling channel of each of the first and second modules,
wherein a plurality of guide protrusions extends on a lower surface of the floor surface in a second direction perpendicular to the first direction, the plurality of guide protrusions being spaced apart from each other in the first direction, and
