Claim 9:
10. A battery pack comprising:
a plurality of modules, each module of the plurality of modules comprising:
a cell stack comprising a plurality of unit cells aligned in a first direction and an insulating member around the plurality of unit cells; and
a module housing having a plurality of receiving parts, the cell stack being in one of the plurality of receiving parts,
wherein the one of the plurality of receiving parts comprises a fixing wall around the cell stack and having at least a first portion in contact with the cell stack,
wherein a cooling channel for a coolant to flow through is located below a bottom surface of the module housing rather than inside the fixing wall,
wherein the module housing comprises the bottom surface, an outer wall around the bottom surface, end walls extending in a second direction perpendicular to the first direction in an inner space defined by the outer wall, and a separation wall extending between the end walls in the first direction,
wherein one of the end walls corresponds to a second portion of the fixing wall,
wherein one surface of the one of the end walls faces the outer wall of the module housing and is spaced apart from the outer wall along the first direction to form a first impact absorbing space between the end wall and the outer wall, and
wherein the end walls, the separation wall, and the outer wall of the module housing are integral with the bottom surface of the module housing.
