Abstract

A battery cell carrier assembly having a battery cell carrier for holding a battery cell is provided. The battery cell carrier includes a trapping member for holding the battery cell. The battery cell carrier has at least one aperture extending therethrough for allowing air to flow therethrough to contact the first side of the battery cell for cooling the battery cell. The battery cell carrier further includes a panel member configured to be coupled to the trapping member for holding the battery cell therebetween. The panel member has at least one aperture extending therethrough for allowing air to flow therethrough to contact the battery cell for cooling the battery cell.

Claims

1. A battery cell carrier for holding a battery cell therein, the battery cell having a first side and a second side opposite the first side, comprising:

a trapping member configured to contact at least a portion of the first side of the battery cell, the trapping member having at least one aperture extending therethrough, for allowing air to flow therethrough to contact the first side of the battery cell for cooling the battery cell; and

a panel member configured to contact at least a portion of the second side of the battery cell, the panel member further configured to engage a portion of the trapping member such that the battery cell is held between the panel member and fire trapping member, the panel member having at least one aperture extending therethrough for allowing air to flow therethrough to contact the second side of the battery cell for cooling the battery cell.

2. The battery cell carrier of claim 1, wherein the trapping member has a peripheral wall, the peripheral wall having a first slot extending therethrough at a first end of the trapping member and a second slot extending therethrough at a second end of the trapping member, the first and second slots configured to receive first and second terminals, respectively, of the battery cell therethrough.

3. The battery cell carrier of claim 1, wherein the trapping member has a peripheral wall defining a groove configured to receive a gasket therein, the gasket being disposed at least partially in the groove such that the gasket contacts the battery cell when the panel member engages the trapping member.

4. The battery cell carrier of claim 1, wherein the trapping member has a peripheral wall, the peripheral wall having a venting aperture extending therethrough for venting any gases escaping from the battery cell.

5. A battery cell carrier assembly for holding first and second battery cells therein, comprising:

a first battery cell carrier having a first trapping member and a first panel member, the first trapping member configured to contact at least a portion of a first side of the first battery cell, the first trapping member having at least one aperture extending therethrough for allowing air to flow therethrough to contact the first side of the first battery cell for cooling the first battery cell, the first panel member configured to contact at least a portion of a second side of the first battery cell opposite the first side, the first panel member further configured to engage a portion of the first trapping member such that the first battery cell is held between the first panel member and the first trapping member, the first panel member having at least one aperture extending therethrough for allowing air to flow therethrough to contact the second side of the first battery cell for cooling the first battery cell; and

a second battery cell carrier having a second trapping member and a second panel member, the second trapping member configured to engage the first panel member of the first battery cell carrier, the second trapping member further configured to contact at least a portion of a third side of the second battery cell, the second trapping member having at least one aperture extending therethrough for allowing air to flow therethrough to contact the third side of the second battery cell, the second panel member configured to contact at least a portion of a fourth side of the second battery cell opposite the third side, the second panel member further configured to engage a portion of the second trapping member such that the second battery cell is held between the second panel member and the second trapping member, the second panel member having at least one aperture extending therethrough for allowing air to flow therethrough to contact the fourth side of the second battery cell for cooling the second battery cell.

6. The battery cell carrier assembly of claim 5, wherein the first trapping member having a peripheral wall, the peripheral wall having a first slot extending therethrough at a first end of the first trapping member and a second slot extending therethrough at a second end of the first trapping member, the first and second slots configured to receive first and second terminals, respectively, of the first battery cell therethrough.

7. The battery cell carrier assembly of claim 5, wherein the first trapping member has a peripheral wall defining a groove configured to receive a gasket therein, the gasket being disposed at least partially in the groove such that the gasket contacts the battery cell when the first panel member engages the first trapping member.

8. The battery cell carrier assembly of claim 5, wherein the first trapping member has a peripheral wall, the peripheral wall having a venting aperture extending therethrough for venting any gases escaping from the first battery cell.

9. A method for assembling a battery cell carrier for holding a battery cell therein, the battery cell carrier comprising a trapping member and a panel member, the method comprising:

disposing the battery cell on the trapping member, the trapping member having at least one aperture extending therethrough for allowing air to contact a first side or the battery cell for cooling the battery cell; and

disposing the panel member on the trapping member such that the battery cell is held between the panel member and the trapping member, the panel member having at least one aperture extending therethrough for allowing air to contact a second side of the battery cell for cooling the battery cell.

10. The method of claim 9, further comprising fixedly coupling the trapping member to the panel member.

11. A method for assembling a battery cell carrier assembly for holding first and second battery cells therein, the battery cell carrier assembly having a first battery cell carrier with a first trapping member and a first panel member, and a second battery cell carrier with a second trapping member and a second panel member, the method comprising:

disposing the first battery cell on the first trapping member, the first trapping member having at least one aperture extending therethrough for allowing air to contact a first side of the first battery cell for cooling the first battery cell;

disposing the first panel member on the first trapping member to form the first battery cell carrier such that the first battery cell is held between the first panel member and the first trapping member, the first panel member having at least one aperture extending therethrough for allowing air to contact a second side of the first battery cell for cooling the first battery cell;

disposing the second battery cell on the second trapping member, the second trapping member having at least one aperture extending therethrough for allowing air to contact a third side of the second battery cell for cooling the second battery cell;

disposing the second panel member on the second trapping member to form the second battery cell carrier such that the second battery cell is held between the second panel member and the second trapping member, the second panel member having at least one aperture extending therethrough for allowing air to contact a fourth side of the second battery cell for cooling the second battery cell; and

disposing the first battery cell carrier on the second battery cell carrier to form the battery cell carrier assembly.
