Abstract

A battery cell assembly includes a pouch-type battery cell having a battery member, an external housing, and first and second electrical terminals. The external housing has a central housing portion and a peripheral lip member extending around a periphery of the central housing portion. The central housing portion encloses the battery member therein. The first and second electrical terminals are electrically coupled to the battery member and extend outwardly from the peripheral lip member. The assembly further includes a first tube disposed against the peripheral lip member of the external housing. The peripheral lip member extends around the first tube such that the first tube is at least partially disposed within a first interior region defined by the peripheral lip member.

First claim

What is claimed is:

1 . A battery cell assembly, comprising:
a pouch-type battery cell having a battery member, an external housing, and first and second electrical terminals; the external housing having a central housing portion and a peripheral lip member extending around a periphery of the central housing portion, the central housing portion enclosing the battery member therein, the first and second electrical terminals electrically coupled to the battery member and extending outwardly from the peripheral lip member; and a first tube being disposed against the peripheral lip member of the external housing, the peripheral lip member extending around the first tube such that the first tube is at least partially disposed within a first interior region defined by the peripheral lip member.

2 . The battery cell assembly of claim 1 , wherein the first tube is configured to receive heat energy from the pouch-type battery cell and to transfer at least a portion of the received heat energy to a fluid flowing through the first tube to cool the pouch-type battery cell.

3 . The battery cell assembly of claim 1 , wherein an end portion of the first tube extends outwardly from the peripheral lip member and is not enclosed by the peripheral lip member.

4 . The battery cell assembly of claim 1 , wherein the peripheral lip member includes first, second, third and fourth peripheral lip portions, the first and second peripheral lip portions extending substantially parallel to one another, the third and fourth peripheral lip portions extending substantially parallel to one another and substantially perpendicular to the first and second peripheral lip portions.

5 . The battery cell assembly of claim 4 , wherein the first tube comprises first, second, and third tube portions, the first and second tube portions extending substantially parallel to one another, the third tube portion extending between the first and second tube portions substantially perpendicular to the first and second tube portions.

6 . The battery cell assembly of claim 5 , wherein the first tube portion of the first tube is disposed against the first peripheral lip portion of the peripheral lip member of the external housing, the first peripheral lip portion extending around the first tube portion such that the first tube portion is at least partially disposed within an interior space defined by the first peripheral lip portion.

7 . The battery cell assembly of claim 6 , wherein the first peripheral lip portion is wrapped around the first tube portion, and an end portion of the first peripheral lip portion is coupled to another portion of the first peripheral lip portion proximate to the central housing portion.

8 . The battery cell assembly of claim 6 , wherein the second tube portion of the first tube is disposed against the second peripheral lip portion of the peripheral lip member of the external housing, the second peripheral lip portion extending around the second tube portion such that the second tube portion is at least partially disposed within an interior space defined by the second peripheral lip portion.

9 . The battery cell assembly of claim 8 , wherein the third tube portion of the first tube is disposed against the third peripheral lip portion of the peripheral lip member of the external housing, the third peripheral lip portion extending around the third tube portion such that the third tube portion is at least partially disposed within an interior space defined by the third peripheral lip portion.

10 . The battery cell assembly of claim 4 , wherein the first and second electrical terminals extend outwardly from the fourth peripheral lip portion of the peripheral lip member.

11 . The battery cell assembly of claim 1 , wherein the first tube is an aluminum tube.

12 . The battery cell assembly of claim 1 , further comprising a second tube being disposed against the peripheral lip member of the external housing, the peripheral lip member extending around the second tube such that the second tube is at least partially disposed within a second interior region defined by the peripheral lip member.

13 . The battery cell assembly of claim 12 , wherein the second tube is configured to receive heat energy from the pouch-type battery cell and to transfer at least a portion of the received heat energy to a fluid flowing through the second tube to cool the pouch-type battery cell.

14 . The battery cell assembly of claim 12 , wherein the peripheral lip member includes first and second peripheral lip portions extending substantially parallel to one another, the central housing portion being disposed between the first and second peripheral lip portions.

15 . The battery cell assembly of claim 14 , wherein the first tube is disposed against the first peripheral lip portion of the peripheral lip member of the external housing, the first peripheral lip portion extending around the first tube such that the first tube is at least partially disposed within an interior space defined by the first peripheral lip portion.

16 . The battery cell assembly of claim 15 , wherein the first peripheral lip portion is wrapped around the first tube, and an end portion of the first peripheral lip portion is coupled to another portion of the first peripheral lip portion proximate to the central housing portion.

17 . The battery cell assembly of claim 15 , wherein the second tube is disposed against the second peripheral lip portion of the peripheral lip member of the external housing, the second peripheral lip portion extending around the second tube such that the second tube is at least partially disposed within an interior space defined by the second peripheral lip portion.

18 . The battery cell assembly of claim 14 , wherein the peripheral lip member further includes third and fourth peripheral lip portions extending substantially parallel to one another and substantially perpendicular to the first and second peripheral lip portions, the first and second electrical terminals extending outwardly from the third and fourth peripheral lip portions, respectively.
