BATTERY MODULE AND BATTERY PACK COMPRISING SAME

A battery module according to one embodiment of the present disclosure includes: a battery cell stack in which a plurality of battery cells are stacked; a module frame that houses the battery cell stack; a first end plate and a second end plate that cover one side and the other side of the battery cell stack, respectively; a heat sink that is located under the bottom part of the module frame; a coolant injection port that supplies coolant to the heat sink; and a coolant discharge port that discharges the coolant from the heat sink. The first end plate comprises a first mounting parts that is formed on one surface of the first end plate. The module frame includes a first module frame protrusion and a second module frame protrusion that protrude from the bottom part of the module frame so as to pass through the first end plate. The coolant injection port is located on the first module frame protrusion, and the coolant discharge port is located on the second module frame protrusion. The coolant injection port and the coolant discharge port are spaced apart from each other along the width direction of the first end plate, and the first mounting parts are located between the coolant injection port and the coolant discharge port.
