SYSTEM AND METHOD FOR ROLLER INTERCONNECTION OF BATTERY CELLS
First Claim
1. A battery module, comprising:
- a power assembly comprising a first battery cell and a second battery cell in a stacked orientation relative to each other, wherein the first battery cell comprises a first tab electrode extending therefrom, and wherein the second battery cell comprises a second tab electrode extending therefrom; and
an interconnect assembly configured to facilitate electrically coupling the first tab electrode with the second tab electrode, wherein the interconnect assembly comprises;
a roller housing structure about which the first and second tab electrodes at least partially conform such that the first and second tab electrodes are positioned in an opening defined by the roller housing structure; and
a roller disposed in the opening of the roller housing structure such that the first and second tab electrodes are secured in electrical communication.

Abstract
A battery module includes a power assembly including a first battery cell and a second battery cell in a stacked orientation relative to each other. The first battery cell includes a first tab electrode extending therefrom, and the second battery cell includes a second tab electrode extending therefrom. The battery module also includes an interconnect assembly configured to facilitate electrically coupling the first tab electrode with the second tab electrode. The interconnect assembly includes a roller housing structure about which the first and second tab electrodes at least partially conform such that the first and second tab electrodes are positioned in an opening defined by the roller housing structure. The interconnect assembly also includes a roller disposed in the opening of the roller housing structure such that the first and second tab electrodes are secured in electrical communication.
