A battery module comprising:
- a battery cell stack in which a plurality of battery cells are stacked;
- a first frame having a bottom surface and opposite side surfaces respectively covering a lower side surface and opposite side surfaces of the battery cell stack;
- and
- a second frame having an upper surface and front and rear surfaces respectively covering an upper side surface and front and rear surfaces of the battery cell stack,
- wherein the upper surface of the second frame and the front and rear surfaces of the second frame are integrally formed,
- wherein the upper surface of the second frame and the front and rear surfaces of the second frame are connected to each other via at least one frame connecting part,
- wherein the at least one frame connecting part is bent in a vertical direction to vertically connect the front and rear surfaces of the second frame and the upper surface of the second frame.
A method of manufacturing a battery module, the method comprising:
- manufacturing a first frame having a lower surface and opposite side surfaces;
- manufacturing a second frame through a press method;
- coupling the first frame to a battery cell stack;
- coupling the second frame to the battery cell stack;
- and
- coupling the first frame and the second frame,
- wherein in manufacturing the second frame, forming front and rear surfaces of the second frame is further included to integrally form an upper surface and the front and rear surfaces, and at least one frame connecting part formed in the second frame is bent through the press method to form the upper surface and the front and rear surfaces of the second frame, and
- wherein the at least one frame connecting part is bent in a vertical direction to vertically connect the front and rear surfaces of the second frame and the upper surface of the second frame.
