Abstract

A battery assembly according to an exemplary aspect of the present disclosure includes, among other things, a compression limiter including a body and an attachment head near a first end of the body and configured to engage a structural member of the battery assembly.

First claim

What is claimed is:

1 . A battery assembly, comprising:
a compression limiter including:
a body; and
an attachment head near a first end of said body and configured to engage a structural member of said battery assembly.

2 . The assembly as recited in claim 1 , wherein said body extends between said first end and a second end and is conical-shaped.

3 . The assembly as recited in claim 2 , wherein said body tapers in a direction from said first end toward said second end.

4 . The assembly as recited in claim 1 , wherein said attachment head includes a flange and an arm spaced from said flange.

5 . The assembly as recited in claim 4 , wherein said arm extends along a transverse angle from said body toward said flange.

6 . The assembly as recited in claim 4 , comprising a recess formed between said flange and said arm.

7 . The assembly as recited in claim 6 , wherein said recess extends between an underside of said flange and said arm.

8 . The assembly as recited in claim 1 , comprising a passage formed through said body and configured to receive a fastener.

9 . The assembly as recited in claim 1 , wherein said compression limiter is axially disposed between a first battery array and a second battery array.

10 . The assembly as recited in claim 1 , wherein said structural member is an extension of a side wall of a battery array of said battery assembly.

11 . The assembly as recited in claim 10 , wherein said extension extends above a top surface of a battery cell of said battery array.

12 . The assembly as recited in claim 1 , wherein said compression limiter extends toward a tray of said battery assembly.

13 . A battery assembly, comprising:
a plurality of battery cells; a support structure extending about said plurality of battery cells; and a compression limiter configured to engage a portion of said support structure.

14 . The assembly as recited in claim 13 , wherein said portion is a side wall of said support structure.

15 . The assembly as recited in claim 14 , wherein said side wall includes an extension that extends above a top surface of said plurality of battery cells.

16 . The assembly as recited in claim 13 , wherein said compression limiter includes a body and an attachment head near a first end of said body.

17 . The assembly as recited in claim 16 , wherein said attachment head includes a flange and at least two arms that are spaced from said flange.

18 . The assembly as recited in claim 17 , comprising a recess formed between said flange and one of said at least two arms, said portion of said support structure extending into said recess.
