Abstract
A middle- or large-sized battery pack case is provided in which a battery module having a plurality of stacked battery cells is mounted, wherein the battery pack case is provided with a coolant inlet port and a coolant outlet port, which are disposed such that a coolant for cooling the battery cells can flow from one side to the other side of the battery module in the direction perpendicular to the stacking direction of the battery cells. The battery pack case includes beads formed in a concavo-convex shape for improving the structural stability of the battery pack case against an external force, the beads being constructed in a structure in which the beads do not disturb the flow of the coolant from the coolant inlet port along the advancing direction of a fluid in a flow space defined between the coolant inlet port and the battery module.
