1. A battery module, comprising:
- a polymer housing comprising;
a lower housing portion having a first opening defined therein; and
a housing cover disposed partially over the first opening in the lower housing portion, wherein the housing cover comprises a second opening defined therein having a raised collar extending circumferentially around the second opening;
a bus bar disposed within the polymer housing and electrically coupled to a group of electrically interconnected battery cells disposed within the lower housing portion; and
a major terminal comprising a base that is electrically coupled to the bus bar, wherein the base is secured within the first opening of the lower housing portion by the housing cover and is aligned with the second opening of the housing cover, wherein the base is configured to receive a post within the first opening to removably electrically couple the major terminal to an external load without exposed conductive components at an outer surface of the polymer housing.

Abstract
The present disclosure includes a group of electrically interconnected battery cells disposed within a housing. The disclosure also includes a major terminal of a battery module configured to be coupled to a load for powering the load. One or more portions of the major terminal are disposed within a recess in a surface of the housing. The present disclosure also includes a bus bar that provides an electrical pathway between the group of electrically interconnected battery cells and the major terminal. The bus bar is disposed within the housing.

7. A battery module, comprising:
-
a polymer housing comprising; a lower housing portion having a first opening defined therein; and a housing cover disposed partially over the first opening in the lower housing portion, wherein the housing cover comprises a second opening defined therein having a raised collar extending circumferentially around the second opening; an electrochemical cell having a minor terminal disposed within the polymer housing; a major terminal electrically coupled to the electrochemical cell, wherein the major terminal comprises; a base secured within the first opening of the lower housing portion and aligned with the second opening in the housing cover; and a post electrically coupled to a load and removably engaged directly with the base within the first opening to electrically couple the major terminal to the load, wherein the base consists essentially of a first conductive material and the post consists essentially of a second conductive material different than the first conductive material; and a bus bar that provides an electrical path between the minor terminal of the electrochemical cell and the major terminal of the battery module. - View Dependent Claims (8, 9, 10, 12, 13)
