Abstract

The apparatus can include a first member defining a first channel. The apparatus can include a second member defining a second channel. The first member can be configured to interface with a first side of a battery cell and the second member can be configured to interface with a second side of the battery cell.

First claim

What is claimed is:

1 . An apparatus, comprising:
a first member defining a first channel; a second member having a first member side and a second member side opposite the first member side, the first member side facing the first member, the second member defining a second channel that extends along the first member side and a third channel that extends along the second member side, wherein the second channel is opposite from and adjacent to the third channel; the first member configured to interface with a first side of a first battery cell; the first member side of the second member configured to interface with a second side of the first battery cell and the second member side of the second member configured to interface with a first side of a second battery cell; the first member comprising a first inlet and a first outlet; the second member comprising a second inlet and a second outlet; and a manifold extending between the first outlet and the second inlet to fluidly couple the first member with the second member.

2 . The apparatus of claim 1 , wherein the first member and the second member are extrusions, and wherein the extrusions are configured to interface with the first side and the second side of the battery cell to control a temperature of the battery cell.

3 . The apparatus of claim 1 , comprising:
the first member disposed parallel with the second member, wherein the first side of the battery cell is disposed opposite the second side of the battery cell.

4 . The apparatus of claim 1 , comprising:
the first member comprising a first inlet and a first outlet, the first channel comprising a single pass extending a length of the first member to fluidly couple the first inlet with the first outlet; and the second member comprising a second inlet and a second outlet, the second channel comprising a single pass extending a length of the second member to fluidly couple the second inlet with the second outlet.

5 . The apparatus of claim 1 , comprising:
the first member comprising a first inlet and a first outlet, the first channel comprising a plurality of passes extending along a length of the first member to fluidly couple the first inlet with the first outlet; and the second member comprising a second inlet and a second outlet, the first channel comprising a plurality of passes extending along a length of the second member to fluidly couple the second inlet with the second outlet.

6 . The apparatus of claim 1 , comprising:
the first member comprising a first end and a second end, the first end defining an inlet to receive a fluid and the second end defining an outlet to expel the fluid, the first channel comprising a serpentine configuration to fluidly couple the inlet with the outlet.

7 . The apparatus of claim 1 , wherein the first channel has a sinusoidal configuration comprising a plurality of waves extending between a top of the first member and a bottom of the first member.

8 . The apparatus of claim 1 , comprising:
the second channel fluidly coupled with the third channel to facilitate fluid flowing from the second channel to the third channel.

9 . The apparatus of claim 1 , comprising:
a first element to be disposed between the first member and the first side of the first battery cell; and a second element to be disposed between the second member and the second side of the first battery cell, the first element and the second element comprising thermal properties configured to facilitate heat transfer between the first battery cell and the first and second members.

10 . The apparatus of claim 1 , wherein the battery cell is a prismatic battery cell, wherein the first side of the prismatic battery cell is flat to interface with a flat member side of the first member and the second side of the prismatic battery cell is flat to interface with a flat member side of the second member.

11 . The apparatus of claim 1 , wherein the first member and the second member are structural members of a battery pack configured to support other components of the battery pack.

12 . The apparatus of claim 1 , comprising:
a plurality of battery cells; a first side of each of the plurality of battery cells configured to interface with the first member and a second side of each of the plurality of battery cells configured to interface with the second member; and the first channel configured to facilitate heat transfer with the first side of each of the plurality of battery cells and the second channel configured to facilitate heat transfer with the second side of each of the plurality of battery cells.

13 . The apparatus of claim 1 , comprising:
the first member side of the second member to interface with the second side of the first battery cell to thermally couple the second channel with the first battery cell and the second member side of the second member to interface with the second battery cell to thermally couple the third channel with the second battery cell; and the first member to interface with the first side of the first battery cell to thermally couple the first channel with the first battery cell.

14 . A battery pack, comprising:
a first battery cell and a second battery cell disposed within the battery pack; a first member defining a first channel; a second member having a first member side and a second member side opposite the first member side, the first member side facing the first member, the second member defining a second channel that extends along the first member side and a third channel that extends along the second member side, wherein the second channel is opposite from and adjacent to the third channel; the first member configured to interface with a first side of the first battery cell; the first member side of the second member configured to interface with a second side of the first battery cell and the second member side of the second member configured to interface with a first side of the second battery cell; the first member comprising a first inlet and a first outlet; the second member comprising a second inlet and a second outlet; and a manifold extending between the first outlet and the second inlet to fluidly couple the first channel with the second channel to facilitate fluid transfer from the first inlet to the second outlet.

15 . A method, comprising:
providing a first member and a second member, the first member defining a first channel, and the second member having a first member side and a second member side opposite the first member side, the first member side facing the first member, the second member defining a second channel that extends along the first member side and a third channel that extends along the second member side, wherein the second channel is opposite from and adjacent to the third channel; interfacing the first member with a first side of a first battery cell; interfacing the first member side of the second member with a second side of the first battery cell; interfacing the second member side of the second member with a first side of a second battery cell; and connecting the first channel with the second channel via a manifold, the manifold extending from an outlet of the first channel to an inlet of the second channel.
