Abstract

There is provided a battery system having a plurality of battery modules having joined top, bottom and side surfaces. The battery modules are connected for providing a power source. Each of the plurality of battery modules includes a vent having a discharge outlet. The vent includes a portion that extends outward from a side of the battery module. A gas manifold having a gas discharge tube extending from a first end to a second end includes a plurality of tubular ports positioned between the first and second ends of the gas discharge tube. The plurality of tubular ports extend radially outward from the gas discharge tube and are coupled to each of the vents of the plurality of battery modules.

Claims

1. A gas manifold for use with a battery module comprising:

a gas discharge tube extending from a first end to a second end;

a plurality of tubular ports positioned between the first and second ends of the gas discharge tube, the plurality of tubular ports extending radially outward from the gas discharge tube;

wherein the plurality of tubular ports are flexible for adjusting a position of the gas manifold when attached to the battery module.

2. The gas manifold of claim 1 wherein each of the plurality of tubular ports includes a neck portion connected to the gas discharge tube and extending longitudinally outward and an engagement portion extending longitudinally from the neck portion.

3. The gas manifold of claim 2 wherein the neck portion extends longitudinally outward a sufficient distance to allow for adjusting a position of the gas manifold when attached to the battery module.

4. The gas manifold of claim 3 wherein the neck portion extends longitudinally outward a distance of from 1 to 170 millimeters.

5. The gas manifold of claim 2 wherein the neck portion and engagement portions include an inner surface separated from an outer surface by a thickness.

6. The gas manifold of claim 5 wherein the thickness of the neck portion is less than the thickness of the engagement portion.

7. The gas manifold of claim 5 wherein the thickness of the neck portion is from 0.5 to 6 millimeters allowing displacement of the tubular ports relative to the gas discharge tube.

8. The gas manifold of claim 2 wherein the neck portion has a material flexibility greater of the engagement portion.

9. The gas manifold of claim 2 wherein the neck portion is formed of a material having flexibility greater than a material of the engagement portion.

10. The gas manifold of claim 2 wherein the inner surface of the engagement portion includes an attachment feature formed thereon.

11. The gas manifold of claim 10 wherein the attachment feature includes an angled surface angling outward from the inner surface toward the outer surface of the engagement portion, the angled surface terminating at a ledge.

12. A battery system comprising:

a plurality of battery modules having joined top, bottom and side surfaces, the plurality of battery modules connected for providing a power source, each of the plurality of battery modules having a vent, the vent having a portion extending outward from a side of the battery module; and

a gas manifold having a gas discharge tube extending from a first end to a second end and a plurality of tubular ports positioned between the first and second ends of the gas discharge tube, the plurality of tubular ports extending radially outward from the gas discharge tube and coupled to each of the vents of the plurality of battery modules.

13. The battery system of claim 12 wherein the plurality of tubular ports are flexible for adjusting a position of the gas manifold when coupled to each of the vents of the plurality of battery modules.

14. The battery system of claim 12 wherein each of the plurality of tubular ports includes a neck portion connected to the gas discharge tube and extending longitudinally outward and an engagement portion extending longitudinally from the neck portion.

15. The battery system of claim 14 wherein the neck portion extends longitudinally outward a sufficient distance to allow for adjusting a position of the gas manifold when attached to the battery module.

16. The battery system of claim 14 wherein the neck portion and engagement portions include an inner surface separated from an outer surface by a thickness.

17. The battery system of claim 16 wherein the inner surface of the engagement portion includes an attachment feature formed thereon, the attachment feature having an angled surface angling outward from the inner surface toward the outer surface of the engagement portion, the angled surface terminating at a ledge.

18. The battery system of claim 17 wherein the vent includes a tubular section extending downward from the portion extending outward from the side of the battery module.

19. The battery system of claim 17 wherein the vent includes a barb associated therewith, the barb operative to engage the angled surface and ledge of the attachment feature formed on the inner surface of the engagement portion for coupling the plurality of tubular ports to each of the vents.

20. A battery system comprising:

a plurality of battery modules having joined top, bottom and side surfaces, the plurality of battery modules connected for providing a power source, each of the plurality of battery modules having a vent, the vent having a portion extending outward from a side of the battery module; and

a gas manifold having a gas discharge tube extending from a first end to a second end and a plurality of tubular ports positioned between the first and second ends of the gas discharge tube, the plurality of tubular ports extending radially outward from the gas discharge tube and coupled to each of the vents of the plurality of battery modules wherein the plurality of tubular ports are flexible for adjusting a position of the gas manifold when coupled to each of the vents of the plurality of battery modules.
