Abstract

A battery module having a cooling manifold is provided. The battery module includes a plurality of battery cell assemblies having a plurality of heat exchangers. The battery module further includes a first cooling manifold having a first inlet aperture extending therethrough and a first plurality of outlet apertures extending therethrough. The battery module further includes a first plurality of ported screws disposed through the first plurality of outlet apertures and configured to fluidly and physically couple the plurality of heat exchangers to the first cooling manifold.

Claims

1. A battery module, comprising:

a plurality of battery cell assemblies having a plurality of heat exchangers;

a first cooling manifold having a first inlet aperture extending therethrough and a first plurality of outlet apertures extending therethrough; and

a first plurality of ported screws disposed through the first plurality of outlet apertures and configured to fluidly and physically couple the plurality of heat exchangers to the first cooling manifold.

2. The battery module of claim 1, further comprising:

a second cooling manifold having a first plurality of inlet apertures extending therethrough and a first outlet aperture extending therethrough; and

a second plurality of ported screws disposed through the first plurality of inlet apertures and configured to fluidly and physically couple the plurality of heat exchangers to the second cooling manifold.

3. The battery module of claim 1, wherein each screw of the first plurality of ported screws has a head portion coupled to a threaded portion, and an aperture extending through both the head portion and the threaded portion.

4. The battery module of claim 1, wherein each screw of the first plurality of ported screws are constructed from steel.

5. The battery module of claim 1, wherein the first cooling manifold is constructed of plastic.

6. The battery module of claim 1, wherein each battery cell assembly has a battery cell.

7. A method for cooling a battery module, the battery module having a plurality of battery cell assemblies and a first cooling manifold, the plurality of battery cell assemblies having a plurality of heat exchangers, the method comprising:

routing fluid through a first inlet aperture of the first cooling manifold into the first cooling manifold, the first cooling manifold further having a first plurality of outlet apertures extending therethrough; and

routing the fluid through a first plurality of ported screws disposed through the first plurality of outlet apertures to the plurality of heat exchangers of the battery cell assemblies to cool the plurality of battery cell assemblies.

8. The method of claim 7, further comprising:

routing the fluid from the plurality of heat exchangers through a second plurality of ported screws disposed through a first plurality of inlet apertures of a second cooling manifold and into the second cooling manifold; and

routing the fluid through a first outlet port of the second cooling manifold.
