Battery Module And Battery Pack Comprising Same

Abstract: A battery module according to an embodiment of the present invention comprises: a battery cell stack in which a plurality of battery cells are stacked; a module frame which accommodates the battery cell stack; a first end plate and a second end plate which cover one side and the other side of the battery cell stack, respectively; a heat sink located below the bottom of the module frame; a refrigerant injection port for supplying a refrigerant to the heat sink; and a refrigerant discharge port for discharging the refrigerant from the heat sink. The first end plate includes first mounting portions formed on one surface of the first end plate. The module frame includes a first module frame protrusion and a second module frame protrusion which protrude from the bottom of the module frame so as to pass through the first end plate. The refrigerant injection port is located on the first module frame protrusion, and the refrigerant discharge port is located on the second module frame protrusion. The refrigerant injection port and the refrigerant discharge port are spaced apart from each other along the width direction of the first end plate, and the first mounting portions are located between the refrigerant injection port and the refrigerant discharge port.
