Abstract

A battery array frame according to an exemplary aspect of the present disclosure includes, among other things, a frame body extending along a longitudinal axis and including a top frame rail, a bottom frame rail and frame arms that connect between the top frame rail and the bottom frame rail. An insert extends inside the frame body.

Claims

1. A battery array frame, comprising:

a monolithic frame body extending along a longitudinal axis and including a top frame rail, a bottom frame rail, and frame arms that connect between said top frame rail and said bottom frame rail, wherein said top frame rail and said bottom frame rail extend horizontally and in parallel with said longitudinal axis and said frame arms extend vertically and are transverse to said longitudinal axis, wherein said top frame rail, said bottom frame rail, and said frame arms circumscribe a pocket that is configured to receive a battery cell; and

an insert embedded inside said bottom frame rail between a top wall and a bottom wall of said bottom frame rail.

2. The battery array frame as recited in claim 1, wherein said top frame rail includes at top surface having a first side and a second side that each include an alternating pattern of rigid snap arms and flexible snaps arms.

3. The battery array frame as recited in claim 1, wherein said metallic insert is made of steel, copper or brass.

4. The battery array frame as recited in claim 1, wherein said insert is made of a different material from said frame body.

5. The battery array frame as recited in claim 1, wherein said bottom frame rail includes a foot, and said insert extends into said foot.

6. The battery array frame as recited in claim 1, wherein said bottom frame rail includes a first foot at a first end and a second foot at a second end, said insert extending through said bottom frame rail between said first foot and said second foot.

7. The battery array frame as recited in claim 1, wherein said bottom frame rail includes a first foot that includes said insert and a second foot that includes a second insert.

8. The battery array frame as recited in claim 1, wherein said insert includes a bent portion inside a foot of said bottom frame rail.

9. The battery array frame as recited in claim 1, wherein said insert includes a plurality of threads.

11. The battery array frame as recited in claim 7, wherein said insert and said second insert are separate inserts.

12. The battery array frame as recited in claim 1, wherein said insert extends in parallel with said longitudinal axis of said frame body.

10. A battery assembly, comprising:

a tray;

a battery array against said tray and including a plurality of array frames each including feet having an embedded metallic insert, wherein said metallic inserts are unexposed and do not protrude outside of said plurality of array frames; and

a bracket secured over said feet and mounted to said tray,

wherein said metallic inserts include a bent portion extending inwardly from a nub of each of said feet.

13. A battery assembly, comprising:

a battery cell;

an array frame receiving said battery cell, said array frame including;

a frame body extending along a longitudinal axis and including a top frame rail, a bottom frame rail, and frame arms between said top frame rail and said bottom frame rail; and

a metallic insert embedded inside said frame body without any portion of said metallic insert protruding outside said frame body;

a thermal fin held within said array frame,

wherein said thermal fin is positioned in abutting contact with said battery cell, and

wherein said thermal fin is a separate structure from said metallic insert.
