Abstract

A battery cell assembly is provided. The battery cell assembly includes a polymeric foam container having first, second, third side walls defining an interior region. The first, second, and third side walls have first, second, and third grooves, respectively, extending therein. The battery cell assembly further includes a first battery cell having a first rectangular-shaped body with first, second, and third peripheral ledge portions. The first battery cell is disposed in the interior region such that first, second, and third peripheral ledge portions thereof are disposed in the first, second, and third grooves, respectively, in the first, second, and third side walls, respectively.

First claim

What is claimed is:

1. A battery cell assembly, comprising:
a polymeric foam container having first, second, and third side walls defining an interior region, and a first unitary polymeric foam assembly defining a bottom wall, a fourth side wall, and a top wall; the first and second side walls extending parallel to one another; the third side wall extending between the first and second side walls and perpendicular to the first and second side walls; the fourth side wall extending between the first and second side walls and perpendicular to the first and second side walls and parallel to the third side wall, the bottom wall being rotatably coupled to the fourth side wall utilizing a first living hinge, the fourth side wall being rotatably coupled to the top wall utilizing a second living hinge; the first living hinge extending parallel to the second living hinge, the first, second, and third side walls having first, second, and third grooves, respectively, extending therein; and
a first battery cell having a first rectangular-shaped body with first, second, and third peripheral ledge portions; the first and second peripheral ledge portions of the first battery cell extending parallel to one another; the third peripheral ledge portion of the first battery cell extending between the first and second peripheral ledge portions of the first battery cell and perpendicular to the first and second peripheral ledge portions of the first battery cell; the first battery cell being disposed in the interior region such that first, second, and third peripheral ledge portions thereof are disposed in the first, second, and third grooves, respectively.

2. The battery cell assembly of claim 1 , wherein the first, second, and third side walls further having fourth, fifth, and sixth grooves, respectively, extending therein; the fourth, fifth, and sixth grooves extending parallel to the first, second, and third grooves, respectively; the battery cell assembly further comprising:
a second battery cell having a first rectangular-shaped body with first, second, and third peripheral ledge portions; the first and second peripheral ledge portions of the second battery cell extending parallel to one another; the third peripheral ledge portion of the second battery cell extending between the first and second peripheral ledge portions of the second battery cell and perpendicular to the first and second peripheral ledge portions of the second battery cell; and
the second battery cell being disposed in the interior region such that first, second, and third peripheral ledge portions thereof are disposed in the fourth, fifth, and sixth grooves, respectively, in the first, second, and third side walls, respectively.

3. The battery cell assembly of claim 1 , further comprising a plastic housing and a housing cover defining an inner space, the polymeric foam container and the first battery cell being disposed in the inner space, the housing cover being disposed over an opening of the plastic housing to enclose the opening, the housing cover being coupled to the plastic housing.

4. The battery cell assembly of claim 1 , wherein the bottom wall has an outer rectangular-shaped surface, an inner rectangular-shaped surface, and first, second, third and fourth trapezoidal-shaped side surfaces; the outer rectangular-shaped surface of the bottom wall being disposed substantially parallel to the inner rectangular-shaped surface of the bottom wall, the outer rectangular-shaped surface of the bottom wall being larger than the inner rectangular-shaped surface of the bottom wall; the first, second, third, and fourth trapezoidal-shaped side surfaces of the bottom wall being coupled to and extending between the outer rectangular-shaped surface and the inner rectangular-shaped surface of the bottom wall.

5. The battery cell assembly of claim 4 , wherein the bottom wall further includes a fourth groove extending into the inner rectangular-shaped surface thereof, the fourth groove extending from the first trapezoidal-shaped side surface to the second trapezoidal-shaped side surface of the bottom wall, the fourth groove sized and shaped to receive a portion of an interconnect assembly therein.

6. The battery cell assembly of claim 4 , wherein the fourth side wall has an outer rectangular-shaped surface, an inner rectangular-shaped surface, and first, second, third and fourth trapezoidal-shaped side surfaces; the outer rectangular-shaped surface of the fourth side wall being disposed substantially parallel to the inner rectangular-shaped surface of the fourth side wall, the outer rectangular-shaped surface of the fourth side wall being larger than the inner rectangular-shaped surface of the fourth side wall; the first, second, third, and fourth trapezoidal-shaped side surfaces of the fourth side wall being coupled to and extending between the outer rectangular-shaped surface and the inner rectangular-shaped surface of the fourth side wall.

7. The battery cell assembly of claim 6 , wherein the first living hinge being disposed between the fourth trapezoidal-shaped side surface of the bottom wall and the first trapezoidal-shaped side surface of the fourth side wall.

8. The battery cell assembly of claim 6 , wherein the top wall has an outer rectangular-shaped surface, an inner rectangular-shaped surface, and first, second, third and fourth trapezoidal-shaped side surfaces; the outer rectangular-shaped surface of the top wall being disposed substantially parallel to the inner rectangular-shaped surface of the top wall, the outer rectangular-shaped surface of the top wall being larger than the inner rectangular-shaped surface of the top wall; the first, second, third, and fourth trapezoidal-shaped side surfaces of the top wall being coupled to and extending between the outer rectangular-shaped surface and the inner rectangular-shaped surface of the top wall.

9. The battery cell assembly of claim 8 , wherein the second living hinge being disposed between the fourth trapezoidal-shaped side surface of the fourth side wall and the first trapezoidal-shaped side surface of the top wall.

10. The battery cell assembly of claim 8 , wherein the top wall further includes a fourth groove extending into the inner rectangular-shaped surface thereof, the fourth groove extending from the first trapezoidal-shaped side surface to the second trapezoidal-shaped side surface of the top wall, the fourth groove sized and shaped to receive a portion of an interconnect assembly therein.

11. The battery cell assembly of claim 1 , wherein the polymeric foam container further includes a second unitary polymeric foam assembly defining the first, second, and third side walls; the first side wall being disposed between and coupled to the second and third side walls, the second side wall being rotatably coupled to the first side wall utilizing a third living hinge; the third side wall being rotatably coupled to the first side wall utilizing a fourth living hinge; the third living hinge extending parallel to the fourth living hinge.

12. The battery cell assembly of claim 11 , wherein the first side wall has an outer rectangular-shaped surface, an inner rectangular-shaped surface, and first, second, third and fourth trapezoidal-shaped side surfaces; the outer rectangular-shaped surface of the first side wall being disposed substantially parallel to the inner rectangular-shaped surface of the first side wall, the outer rectangular-shaped surface of the first side wall being larger than the inner rectangular-shaped surface of the first side wall; the first, second, third and fourth trapezoidal-shaped side surfaces of the first side wall being coupled to and extending between the outer rectangul
