Battery module

1. A battery module, comprising:

a plurality of pouch-type secondary batteries standing in a vertical direction and arranged in a right and left direction;

a plurality of cartridges configured to accommodate the pouch-type secondary batteries in an inner space thereof and stacked in a right and left direction;

a cooling plate made of a thermally-conductive material and disposed at a lower portion of the cartridges so that the cartridges are placed thereon, the cooling plate having an upper surface which is at least partially adhered and fixed to the cartridges by means of an adhesive; and

a plurality of cooling fins, each cooling fin being disposed to contact a surface of a respective secondary battery, and each cooling fin having a lower end contacting the cooling plate at a respective contacting surface,

wherein the plurality of cooling fins includes two adjacent cooling fins that abut against one another with the lower ends of the two adjacent cooling fins forming a shape that corresponds to a shape of the cooling plate at the entirety of the respective contacting surface and that corresponds to a shape of a lower portion of the cartridges, each cartridge being located between a respective battery and an entirety of the lower end of the respective cooling fin,

wherein the cooling plate has a convex portion formed at an upper surface thereof in an upper direction, and

wherein each cartridge has a concave portion formed at the lower portion thereof that has a shape corresponding to the convex portion of the cooling plate.

2. The battery module according to claim 1 ,

wherein a lower surface of each of the two adjacent cooling fins has a concave portion corresponding to and contacting the convex portion of the cooling plate at the respective contacting surface.

3. The battery module according to claim 1 ,

wherein the convex portion of the cooling plate has an inclined surface at least partially having a width gradually decreasing along an upper direction.

4. The battery module according to claim 1 , wherein each cooling fin made of a plate-shaped thermally-conductive material.

5. The battery module according to claim 4 ,

wherein each cooling fin is disposed to at least one of an outermost side of the respective secondary battery and a location between adjacent secondary batteries.

6. The battery module according to claim 4 ,

wherein the lower end of each cooling fin makes surface contact with the respective cartridge and the cooling plate.

7. The battery module according to claim 4 ,

wherein the adhesive is interposed between lower ends of the two adjacent cooling fins, between the lower portion of the respective cartridge and an upper portion of the cooling plate.

8. The battery module according to claim 4 ,

wherein the lower end of each cooling fin is at least partially inclined in one direction.

9. The battery module according to claim 1 ,

wherein a left end and a right end of the cooling plate are bent in an upper direction.

10. The battery module according to claim 1 ,

wherein a lower portion of a respective one of the secondary batteries is placed on an upper portion of a lower unit frame of the respective cartridge.

11. The battery module according to claim 10 ,

wherein at least the lower unit frame of each of the cartridges includes a thermally-conductive polymer or is made of a thermally-conductive material containing a thermally-conductive filler and polymer.

12. The battery module according to claim 10 ,

wherein each of the pouch-type secondary batteries is at least partially adhered and fixed to the cartridge by means of an adhesive.

13. The battery module according to claim 1 ,

wherein the adhesive is a thermally-conductive adhesive.

14. A battery pack, comprising the battery module defined in claim 1 .

15. A vehicle, comprising the battery module defined in claim 1 .
