A battery pack comprising a plurality of battery modules in a stacked arrangement, the plurality of battery modules comprising a first battery module that comprises:

• at least one battery cell comprising a cell lead;
• a cartridge on which the at least one battery cell is mounted;
• and
• a cooling cover comprising a first cooling cover that is coupled to the cartridge and that covers the at least one battery cell,
• wherein the cartridge comprises:
• a seating portion configured to seat at least one battery cell,
• a pressing portion that disposed on the seating portion and that is configured to, based on an external force being applied to the seating portion, apply pressure to a first end of a second cooling cover of a second battery module that neighbors the first battery module in the stacked arrangement, and
• a supporting portion that is disposed on the seating portion, that is spaced apart from the pressing portion, and that supports a second end of the second cooling cover of the second battery module,
• wherein the pressing portion and the supporting portion protrude from one surface of the seating portion toward the cooling cover and face the one surface of the seating portion, and
• wherein the cooling cover comprises:
• a heat conductive plate that is positioned between the pressing portion and the supporting portion of the cartridge and that faces one surface of the at least one battery cell, the heat conductive plate having a first end portion that faces the pressing portion of the cartridge and a second end portion that is opposite to the first end portion and that faces the supporting portion of the cartridge, and
• at least one fastening plate that is bent from the heat conductive plate and that is coupled to the cartridge.
