A refrigerant inlet and a refrigerant outlet are positioned at the upper part and lower part of the pack case in a counter direction so that refrigerant for cooling unit cells flows into the opposite side from one side of the battery module in the direction perpendicular to a cell stacking direction. A flow space ('refrigerant inlet portion') from the refrigerant inlet to the battery module and a flow space ('refrigerant outlet portion') from the battery module to the refrigerant outlet are respectively formed in the pack case. An inner surface of the upper end of the refrigerant inlet portion, which faces the upper end portion of a unit cell stack, has a structure with the surface inclined at a positive (+) angle (A) relative to the upper end surface of the unit cell stack, wherein the surface is inclined to the refrigerant inlet from the opposite end portion of the refrigerant inlet. The refrigerant inlet is inclined at an angle (B) larger than the angle (A) of the inclined surface corresponding to a structure of the inner surface of a device on which the medium and large-sized battery pack case including the battery module is mounted. When the angle (B) of slope of the refrigerant inlet is 20-80 degrees, the angle (A) of slope of the inclined surface is 3-8 degrees.

The unit cells are sequentially stacked in the direction (Z-direction) parallel to the ground to form a single battery module, such that a space for the flow of a refrigerant is provided between unit cells. Two or more battery modules, in which the communication of a refrigerant between the battery modules is blocked, are arranged in the horizontal direction (X-direction) on a plane with respect to the refrigerant inlet direction of a refrigerant inlet to form a battery module group. The refrigerant flow space (refrigerant inlet portion), ranging from the refrigerant inlet to the battery module group, and the refrigerant flow space (refrigerant outlet portion), ranging from the battery module group to a refrigerant outlet, are formed in the pack case. The refrigerant flow channel between the refrigerant inlet portion and the refrigerant outlet portion is configured such that the refrigerant fed through the refrigerant inlet portion passes through each of specific battery modules in the vertical direction (Y-direction) on a plane to cool the specific battery modules, and then the refrigerant is discharged through the refrigerant outlet portion.
