Abstract

An electrical conduction assembly comprising a bus bar holder and a plurality of bus bars. 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 of which includes a respective aperture and a respective recess. Also disclosed is a battery including the electrical conduction assembly.

First claim

What is claimed is:
