Abstract

A battery module assembly includes a first battery cell and a second battery cell. The first battery cell includes a rear surface, a side surface, and a top surface. A second battery cell also includes a front surface, a side surface, and a top surface. The front surface of the second battery cell contacts the rear surface first battery cell. A barrier contacts the side surfaces of both the first battery cell and the second battery cell.

First claim

What is claimed is:

1 . A battery module assembly comprising:
a first battery stack comprising:
a first battery stack first battery cell having a front surface, a side surface, and a top surface, each of the front surface, the side surface, and the top surface being perpendicularly arranged with respect to each other, the surface area of the front surface being greater than the surface area of the side surface, and the surface area of the front surface being greater than the surface area of the top surface; and
a first battery stack second battery cell having a front surface, a side surface, and a top surface, each of the front surface, the side surface, and the top surface being perpendicularly arranged with respect to each other, the surface area of the front surface being greater than the surface area of the side surface, and the surface area of the front surface being greater than the surface area of the top surface;
the front surface of the first battery stack first battery cell being arranged parallel to the front surface of the first battery stack second battery cell, the top surface of the first battery stack first battery cell being arranged coplanar with the top surface of the first battery stack second battery cell, and the side surface of the first battery stack first battery cell being arranged coplanar with the side surface of the first battery stack second battery cell; and
a first barrier having a first surface and a second surface, the first surface of the first barrier being arranged parallel and adjacent to the side surface of the first battery stack first battery cell and the side surface of the first battery stack second battery cell.

2 . The battery module assembly of claim 1 , further comprising a first pair of terminals formed in the top surface of the first battery stack first battery cell and a second pair of terminals formed in the top surface of the first battery stack second battery cell.

3 . The battery module assembly of claim 1 , further comprising a housing having a first panel and a second panel, the first panel being arranged adjacent to the front surface of the first battery stack first battery cell, the second panel being arranged adjacent to a rear surface of the first battery stack second battery cell, the rear surface of the first battery stack second battery cell being arranged parallel to the front surface of the first battery stack second battery cell;
wherein the first panel is configured to be drawn towards the second panel; and wherein the first panel is configured to contact the front surface of the first battery stack first battery cell and the second panel is configured to contact the rear surface of the first battery stack second battery cell as the first panel is drawn towards the second panel.

4 . The battery module assembly of claim 1 , further comprising:
a second battery stack comprising:
a second battery stack first battery cell having a front surface, a side surface, and a top surface, each of the front surface, the side surface, and the top surface being perpendicularly arranged with respect to each other, the surface area of the front surface being greater than the surface area of the side surface, and the surface area of the front surface being greater than the surface area of the top surface; and
a second battery stack second battery cell having a front surface, a side surface, and a top surface, each of the front surface, the side surface, and the top surface being perpendicularly arranged with respect to each other, the surface area of the front surface being greater than the surface area of the side surface, and the surface area of the front surface being greater than the surface area of the top surface;
the front surface of the second battery stack first battery cell being arranged parallel to the front surface of the second battery stack second battery cell, the top surface of the second battery stack first battery cell being arranged coplanar with the top surface of the second battery stack second battery cell, and the side surface of the second battery stack first battery cell being arranged coplanar with the side surface of the second battery stack second battery cell; and
the front surface of the second battery stack first battery cell being arranged coplanar to the front surface of the first battery stack first battery cell.

5 . The battery module assembly of claim 4 , wherein the first barrier is arranged between the first battery stack and the second battery stack and comprises an electrical insulating material.

6 . The battery module assembly of claim 4 , further comprising:
a housing having a first panel and a second panel, the first panel being arranged adjacent to the front surface of the first battery stack first battery cell, the second panel being arranged adjacent to a rear surface of the first battery stack second battery cell, the rear surface of the first battery stack second battery cell being arranged parallel to the front surface of the second battery stack second battery cell; wherein the first barrier is arranged between the first panel and the second panel.

7 . The battery module assembly of claim 4 , wherein the second surface of the first barrier is arranged parallel and adjacent to the side surface of the second battery stack first battery cell and the side surface of the second battery stack second battery cell.

8 . The battery module assembly of claim 4 , wherein the first battery stack, the second battery stack, and the first barrier form a first battery pack, and wherein the battery module assembly further comprises an intermediate panel and a second battery pack, the second battery pack comprising:
a third battery stack comprising:
a third battery stack first battery cell having a front surface, a side surface, and a top surface, each of the front surface, the side surface, and the top surface being perpendicularly arranged with respect to each other, the surface area of the front surface being greater than the surface area of the side surface, and the surface area of the front surface being greater than the surface area of the top surface; and
a third battery stack second battery cell having a front surface, a side surface, and a top surface, each of the front surface, the side surface, and the top surface being perpendicularly arranged with respect to each other, the surface area of the front surface being greater than the surface area of the side surface, and the surface area of the front surface being greater than the surface area of the top surface;
the front surface of the third battery stack first battery cell being arranged parallel to the front surface of the third battery stack second battery cell, the top surface of the third battery stack first battery cell being arranged coplanar with the top surface of the first battery stack second battery cell, and the side surface of the first battery stack first battery cell being arranged coplanar with the side surface of the first battery stack second battery cell;
a fourth battery stack comprising:
a fourth battery stack first battery cell having a front surface, a side surface, and a top surface, each of the front surface, the side surface, and the top surface being perpendicularly arranged with respect to each other, the surface area of the front surface being greater than the surface area of the side surface, and the surface area of the front surface being greater than the surface area of the top surface; and
