Abstract

A secondary battery module includes a plurality of unit batteries, a housing receiving the unit batteries, a cell barrier plate disposed between the unit batteries to transfer heat generated from the unit batteries, a cooling plate disposed in contact with an end of the cell barrier plate, and a heat dissipation assembly disposed proximate to the cooling plate to dissipate heat transferred to the cooling plate.

Claims

1. A secondary battery module comprising:

a plurality of unit batteries;

a cell barrier plate disposed between the unit batteries to transfer heat generated from the unit batteries;

a cooling plate disposed in contact with an end of the cell barrier plate; and

a heat dissipation assembly disposed proximate to the cooling plate to dissipate heat from the cooling plate.

2. The secondary battery module of claim 1, wherein the cooling plate has a heat dissipation rib.

3. The secondary battery module of claim 1, wherein the cell barrier plate extends beyond the unit batteries in at least one direction.

4. The secondary battery module of claim 1, wherein the heat dissipation assembly has at least one cooling fan to move air toward the cooling plate.

5. The secondary battery module of claim 1, wherein the heat dissipation assembly includes at least one thermoelectric element disposed on the cooling plate.

6. The secondary battery module of claim 1, wherein the cooling plate is disposed to face a side surface of the unit batteries.

7. The secondary battery module of claim 1, wherein the cooling plate is disposed in contact with a first end surface of the unit batteries, and wherein the secondary battery module further comprises a second cooling plate disposed in contact with a second end surface of the unit batteries.

8. The secondary battery module of claim 1, wherein the cell barrier plate comprises copper or aluminum.

9. The secondary battery module of claim 1, wherein the cooling plate comprises copper or aluminum.

10. The secondary battery module of claim 1, wherein the unit batteries are square shape batteries.

11. The secondary battery module of claim 1, wherein the cell barrier plate is integrally formed with the cooling plate.

12. The secondary battery module of claim 1, wherein the cell barrier plate is fixed to the cooling plate by welding.

13. The secondary battery module of claim 2, wherein the heat dissipation assembly includes a heat dissipation assembly housing supported on an outer end of the heat dissipation rib, a fan disposed inside the heat dissipation assembly housing to move air toward the heat dissipation rib, and a motor disposed inside the heat dissipation assembly housing and coupled to the fan.

14. The secondary battery module of claim 1, wherein the secondary battery module is adapted to drive a motor.

15. A secondary battery module comprising:

a plurality of unit batteries;

a housing receiving the unit batteries;

a cell barrier plate disposed between the unit batteries to transfer heat generated from the unit batteries; and

a cooling plate disposed in contact with an end of the cell barrier plate,

wherein the housing has an inlet for allowing a flow of a heat transfer medium and a cooling fan is disposed in the inlet.

16. The secondary battery module of claim 15, wherein a cooling rib is disposed on the cooling plate.

17. The secondary battery module of claim 16, wherein the cooling rib is disposed on a surface of the cooling plate facing the inlet.

18. The secondary battery module of claim 15, wherein the cooling plate is disposed in contact with a first side surface of the unit batteries, and wherein the secondary battery module further comprises a second cooling plate disposed in contact with a second side surface of the unit batteries.

19. The secondary battery module of claim 18, further comprising a second inlet for allowing the flow of the heat transfer medium and a second cooling fan within the second inlet.
