Abstract

A battery array according to an exemplary aspect of the present disclosure includes, among other things, a plurality of battery cells, a support structure surrounding the plurality of battery cells and a first lifting feature protruding from a first wall of the support structure.

First claim

What is claimed is:

1. A battery array, comprising:
a plurality of battery cells positioned side-by-side along a longitudinal axis;
a support structure surrounding said plurality of battery cells; and
a first lifting feature protruding from an end wall of said support structure, wherein said end wall is disposed along said longitudinal axis at a longitudinal extent of said plurality of battery cells,
wherein said end wall includes an outer shell and an inner shell, and said first lifting feature includes a tab that protrudes from said outer shell,
wherein said inner shell includes at least one through-hole extending vertically through said inner shell.

2. The battery array as recited in claim 1 , wherein a bent portion of said tab extends above said inner shell.

3. The battery array as recited in claim 1 , wherein a retention bar extends over top of said plurality of battery cells and connects to said tab.

4. The battery array as recited in claim 3 , wherein said tab and said retention bar together establish said first lifting feature.

5. The battery array as recited in claim 1 , comprising a slot that extends between said tab and said inner shell.

6. The battery array as recited in claim 1 , wherein said tab that protrudes outwardly from an outer face of said outer shell in a direction opposite from said plurality of battery cells.

7. The battery array as recited in claim 6 , wherein said tab includes a slot.

8. The battery array as recited in claim 7 , wherein said slot is configured to receive a lifting tool.

9. The battery array as recited in claim 6 , wherein an outermost face of said tab is an outermost surface of said end wall.

10. The battery array as recited in claim 1 , wherein said lifting feature includes a tab that is integrated as part of said support structure.

11. The battery array as recited in claim 1 , comprising a second lifting feature protruding from a second end wall of said support structure, said second end wall on an opposite end of said plurality of battery cells from said end wall.

12. The battery array as recited in claim 1 , wherein said first lifting feature includes a slot configured to receive a lifting tool.

13. The battery array as recited in claim 1 , comprising a retention bar and a bus bar module extending over top of said plurality of battery cells.

14. The battery array as recited in claim 1 , comprising a retention bar extending over top of said plurality of battery cells, and said retention bar is welded to a bent portion of said tab of said first lifting feature.

15. The battery array as recited in claim 1 , wherein said outer shell is metallic and said inner shell is plastic.

16. The battery array as recited in claim 1 , wherein said first lifting feature is stationary relative to said end wall.

17. A battery array, comprising:
a grouping of battery cells stacked side-by-side along a longitudinal axis;
a support structure including opposing end walls disposed along said longitudinal axis at longitudinal extents of said grouping of battery cells, opposing side walls between said opposing end walls, and a retention bar along a top of said grouping of battery cells;
a first lifting tab protruding from one of said opposing end walls, wherein a first bent portion of said first lifting tab is fixedly secured to said retention bar;
a second lifting tab protruding from the other of said opposing end walls, wherein a second bent portion of said second lifting tab is fixedly secured to said retention bar;
a first through-hole extending vertically through said one of said opposing end walls; and
a second through-hole extending vertically through said other of said opposing end walls;
wherein said first or said second through-hole is configured to receive a first portion of a lifting tool and said first or said second lifting tab is configured to receive a second portion of said lifting tool for lifting and moving the battery array.

18. A battery array, comprising:
a grouping of battery cells;
an end wall disposed at a longitudinal extent of said grouping of battery cells and including an outer shell and an inner shell;
a retention bar extending above said grouping of battery cells;
a stationary lifting tab protruding from said outer shell and including a bent portion secured to said retention bar; and
a through-hole extending vertically through said inner shell.
