Abstract

An electrical conduction assembly comprising a flexible layer, an interface being associated with and electrically coupled to a terminal of an external electrical element, and a circuit trace coupled to the flexible layer and to the interface. The circuit trace includes a fuse as part of the trace, and the fuse is associated with the interface. Also disclosed is a battery including the electrical conduction assembly. Further disclosed is a bus bar holder for a battery. The bus bar holder includes a lead-in structure coupled with a main body on a first side. The lead in structure includes a first lead-in wall to be disposed between a first plurality of battery cells and a second lead-in wall orthogonal to the first lead-in wall. The bus bar holder can also include a plurality of pockets, each or which includes a respective aperture and a respective recess.

First claim

What is claimed is:

1 . A bus bar holder for a battery comprising a housing having a wall, a first plurality of battery cells and a second plurality of battery cells housed by the housing, the bus bar holder comprising:
a main body comprising:
a first side to be disposed next to the first plurality of battery cells and the second plurality of battery cells; and
a second side opposite the first side and to be disposed away from the first plurality of battery cells and the second plurality of battery cells; and
a lead-in structure coupled with the main body on the first side, the lead-in structure comprising:
a first lead-in wall to be disposed between the first plurality of battery cells and the second plurality of battery cells;
a second lead-in wall orthogonal to the first lead-in wall, the second lead-in wall to be disposed between the wall of the housing, and the first plurality of battery cells and the second plurality of battery cells; and
the first lead-in wall configured to enter in between the first plurality of battery cells and the second plurality of battery cells housed by the housing to divide the first plurality of battery cells and the second plurality of battery cells from each other and the second lead-in wall configured to provide a fixing force coupling the first plurality of battery cells and the second plurality of battery cells with the housing.

2 . The bus bar holder according to claim 1 , wherein the first lead-in wall and the second lead-in wall are a unitary wall.

3 . The bus bar holder according to claim 1 , wherein the lead-in structure is integrally formed with the main body.

4 . The bus bar holder according to claim 1 , wherein the first lead-in wall is wedge-shaped.

5 . The bus bar holder according to claim 1 , wherein the second lead-in wall is a multi-tiered wall.

6 . The bus bar holder according to claim 5 , wherein a first tier of the second lead-in wall includes a height from the main body similar to a height from the main body for the first lead-in wall.

7 . The bus bar holder according to claim 6 , wherein a second tier of the second lead-in wall includes a height from the main body less than the height from the main body for the first lead-in wall.

8 . The bus bar holder according to claim 5 , wherein a first tier of the multi-tiered wall functions to separate the first plurality of battery cells and the second plurality of battery cells from the wall of the housing and a second tier of the multi-tiered wall functions to urge the first plurality of battery cells and the second plurality of battery cells into a final position within the housing.

9 . The bus bar holder according to claim 1 , wherein the main body further comprises a first plurality of apertures, each one of which to receive a respective cell terminal from one of the first plurality of battery cells or one of the second plurality of battery cells.

10 . The bus bar holder according to claim 1 , wherein the main body further comprises a second plurality of apertures, each one of which to align with a respective vent of one of the first plurality of battery cells or one of the second plurality of battery cells.

11 . A battery comprising:
a housing comprising a first wall and a second wall, the second wall partitioning a first cell compartment from a second cell compartment, the first wall and the second wall defining in part the first cell compartment and the second cell compartment; a first plurality of battery cells housed by the housing and disposed in the first cell compartment; a second plurality of battery cells housed by the housing and disposed in the second cell compartment; and the bus bar holder according to claim 1 .

12 . The battery according to claim 11 , wherein the first wall of the housing includes an indentation having an angled surface, wherein the indentation receives at least a portion of the second lead-in wall.

13 . The battery according to claim 12 , wherein the second wall being orthogonal to the first wall, and wherein the angled surface connects in part the first wall to the second wall.

14 . The battery according to claim 13 , wherein the bus bar holder further comprises a jutting segment, and wherein the jutting segment abuts a portion of the second wall.
