Abstract

A traction battery pack assembly includes an enclosure assembly having a folded enclosure piece and at least one cell stack within an interior of the enclosure assembly. The folded enclosure piece includes a first section that is folded along an axis relative to a second section. The at least one cell stack has one or more battery cells.

First claim

What is claimed is:

1 . A traction battery pack assembly, comprising:
an enclosure assembly having a folded enclosure piece, the folded enclosure piece including a first section that is folded along an axis relative to a second section; and at least one cell stack within an interior of the enclosure assembly, the at least one cell stack having one or more battery cells.

2 . The traction battery pack assembly of claim 1 , further comprising a plate of the enclosure assembly, the at least one cell stack disposed on the plate.

3 . The traction battery pack assembly of claim 2 , wherein the plate is a skid plate.

4 . The traction battery pack assembly of claim 2 , wherein the plate is planar.

5 . The traction battery pack assembly of claim 2 , wherein the folded enclosure piece is adhesively secured to the plate.

6 . The traction battery pack assembly of claim 2 , wherein the folded enclosure piece provides a channel that receives the at least one cell stack.

7 . The traction battery pack assembly of claim 6 , further comprising a first cover and a second cover of the enclosure assembly, the first cover covering a first end of the channel, the second cover covering an opposite, second end of the channel.

8 . The traction battery pack assembly of claim 7 , further comprising at least one connection interface of the first cover, the second cover, or both.

9 . The traction battery pack assembly of claim 7 , wherein the plate is a skid plate.

10 . The traction battery pack assembly of claim 1 , wherein the folded enclosure piece is a metal or metal alloy.

11 . The traction battery pack assembly of claim 1 , wherein the axis is a first axis and the first section is disposed along a first side of the second section, and further comprising a third section that is folded along a second axis relative to the second section and is disposed along an opposite side of the second section.

12 . The traction battery pack assembly of claim 11 , wherein the first axis and the second axis are parallel to each other.

13 . The traction battery pack assembly of claim 11 , wherein the first section and the second section are parallel to each other.

14 . The traction battery pack assembly of claim 11 , further comprising a plate of the enclosure assembly, the at least one cell stack disposed on the plate, wherein the first section and the third section each include a lip that attaches to the plate.

15 . The traction battery pack assembly of claim 11 , wherein the folded enclosure piece is U-shaped.

16 . A traction battery pack cell stack enclosing method, comprising:
folding a first section of a sheet of material about an axis relative to a second section of the sheet of material to provide a folded enclosure piece; and using the first section and the second section to enclose at least one cell stack.

17 . The method of claim 16 , further comprising folding a third section of the folded enclosure piece relative to the first section to establish a channel in the folded enclosure piece.

18 . The method of claim 17 , further comprising positioning the at least one cell stack within the channel in the folded enclosure piece.

19 . The method of claim of claim 18 , further comprising supporting the at least one cell stack directly on a skid plate, and securing the folded enclosure piece directly to the skid plate.
