Abstract

A battery cell connector includes a plurality of segments. Each segment defines a respective plane and has a respective longitudinal axis. The battery cell connector further includes a plurality of bends coupling the plurality of segments together into a 3-D object, each bend located between a unique pair of adjacent segments of the plurality of segments, where the unique pair of adjacent segments define two distinct respective planes. A first segment of the plurality of segments includes one or more first connecting elements for a battery pole of a first battery cell and a second segment of the plurality of segments includes one or more second connecting elements for a battery pole of a second battery cell. The one or more first connecting elements are electrically coupled with the one or more second connecting elements.

First claim

What is claimed is:

1. A battery cell connector, comprising:
a plurality of segments, each segment defining a respective plane in which the segment lies and having a respective longitudinal axis, wherein the plurality of segments includes at least three segments defining three respective planes; and
a plurality of bends coupling the plurality of segments together into a 3-D object having the three respective planes substantially perpendicular to one another, each bend located between a unique pair of adjacent segments of the plurality of segments, wherein the unique pair of adjacent segments define two distinct respective planes, wherein:
a first segment of the plurality of segments includes one or more first connecting elements for a battery pole of a first battery cell;
a second segment of the plurality of segments includes one or more second connecting elements for a battery pole of a second battery cell; and
the one or more first connecting elements are electrically coupled with the one or more second connecting elements.

2. The battery cell connector of claim 1 , further comprising a plurality of turns, each turn coupling a second unique pair of adjacent segments in the plurality of segments, wherein the second unique pair of adjacent segments have distinct respective longitudinal axis within the same respective plane.

3. The battery cell connector of claim 1 , wherein the plurality of segments comprise an electrical conductor forming the electrical coupling between the one or more first connecting elements and the one or more second connecting elements.

4. The battery cell connector of claim 1 , wherein the plurality of segments has an L-shaped opening.

5. The battery cell connector of claim 1 , wherein the plurality of bends comprise vibration dampening elements.

6. The battery cell connector of claim 1 , wherein the plurality of bends includes three bends.

7. The battery cell connector of claim 6 , wherein the three bends have three distinct axes of bending.

8. The battery cell connector of claim 7 , wherein the three distinct axes of bending are substantially perpendicular to one another.

9. The battery cell connector of claim 1 , wherein the plurality of segments includes at least four segments.

10. The battery cell connector of claim 1 , wherein the connector is formed by a continuous metal sheet.

11. The battery cell connector of claim 1 , wherein the connector is made of copper or aluminum.

12. The battery cell connector of claim 1 , wherein the connector is covered with a metal coating layer, and/or an insulating layer.

13. The battery cell connector of claim 1 , further including at least one vibration-absorbent bump formed in a respective segment of the plurality of segments.

14. The battery cell connector of claim 1 , wherein:
the plurality of bends includes a first bend having a first bending axis and a second bend having a second bending axis that is substantially perpendicular to the first; and
the first segment of the plurality of segments and the second segment of the plurality of segments are substantially perpendicular to each other.

15. The battery cell connector of claim 14 , wherein:
the plurality of bends includes only two bends; and
the battery cell connector further comprises a single turn that, together with the two bends, forms the plurality of segments into the 3-D object, wherein the turn couples a second unique pair of adjacent segments in the plurality of segments, wherein the second unique pair of adjacent segments have distinct respective longitudinal axis within the same respective plane.

16. The battery cell connector of claim 14 , wherein the plurality of bends includes a third bend having a third bending axis that is substantially parallel to the first bending axis.
