Battery module and battery pack including same

Abstract

A battery module according to one embodiment of the present invention includes a battery cell stack in which a plurality of battery cells are stacked; a module frame that houses the battery cell stack; first and second end plates that respectively cover one and the other sides of the battery cell stack; a heat sink located below the bottom of the module frame; a refrigerant inlet port that supplies refrigerant to the heat sink; and a refrigerant outlet port that discharges the refrigerant from the heat sink. The first end plate includes a first mounting portion formed on one surface of the first end plate. The module frame includes first and second module frame protrusions that protrude from the bottom of the module frame and pass through the first end plate. The refrigerant inlet port is located on the first module frame protrusion, and the refrigerant outlet port is located on the second module frame protrusion. The refrigerant inlet port and the refrigerant outlet port are located apart from each other along the width direction of the first end plate, and the first mounting portion is located between the refrigerant inlet port and the refrigerant outlet port.
