Abstract

A busbar assembly includes a mesh busbar configured to electrically couple a first component to a second component. An electrical coupling method including securing a mesh busbar to a first component and a second component to electrical couple the first component to the second component.

First claim

What is claimed is:

1. A busbar assembly, comprising:
a mesh busbar configured to electrically couple a first component to a second component wherein the mesh busbar includes a first mesh layer folded over a second mesh layer, wherein the mesh busbar includes a plurality of openings within a mesh area of the mesh busbar; and
a mechanical fastener that extends through at least one of the openings to directly connect the mesh area of the mesh busbar directly to the first component.

2. The busbar assembly of claim 1 , wherein the mesh busbar includes a first mesh area configured to directly connect to the first component, and a second mesh area configured to directly connect to the second component.

3. The busbar assembly of claim 2 , wherein the mesh busbar includes a bend relative to a longitudinal axis of the mesh busbar such that the mesh busbar extends non-linearly from the first mesh area to the second mesh area.

4. The busbar assembly of claim 1 , wherein the plurality of openings includes at least one rounded opening and at least one rectangular opening, the at least one rounded opening receiving the mechanical fastener.

5. The busbar assembly of claim 1 , wherein the mesh busbar includes a third mesh layer folded over the second mesh layer.

6. The busbar assembly of claim 1 , wherein the mesh busbar includes a plurality of individual strands woven in an over-and-under pattern.

7. The busbar assembly of claim 6 , further comprising the first component, wherein the first component is a battery array of a traction battery.

8. The busbar assembly of claim 6 , further comprising the first component, wherein the first component is an electrified vehicle powertrain component.

9. An electrical coupling method, comprising:
clamping a first mesh area of a mesh busbar to a first component and clamping a second mesh area of the mesh busbar to a second component to electrically couple the first component to the second component; and
clamping the first mesh area of the mesh busbar directly to the first component using a first mechanical fastener, and clamping the second mesh area of the mesh busbar directly to the second component using a second mechanical fastener.

10. The method of claim 9 , further comprising communicating fluid through openings to cool the mesh busbar.

11. The method of claim 9 , wherein the mesh busbar includes a first mesh layer folded over a second mesh layer.

12. The method of claim 11 , wherein the mesh busbar includes a plurality of individual strands woven in an over-and-under pattern, wherein at least some of the individual strands extend through both the first layer and the second layer.

13. The method of claim 11 , wherein the mesh busbar includes a third mesh layer folded over the second mesh layer.

14. The method of claim 11 , further comprising securing the mesh busbar to the first component with a fastener that extends through both an opening in the first mesh layer and an opening in the second mesh layer.

15. The busbar assembly of claim 1 , wherein the first mesh layer includes a plurality of individual strands that are folded over to provide part of the second mesh layer.

16. The busbar assembly of claim 15 , wherein the plurality of individual strands extend continuously from the first layer to the second layer.

17. A busbar assembly, comprising:
a first component and a second component;
a mesh busbar electrically coupling the first component to the second component, the mesh busbar includes a first mesh layer folded over a second mesh layer, the mesh busbar including a plurality of individual strands woven in an over-and-under pattern, at least some of the individual strands extending through both the first layer and the second layer;
a first mechanical fastener extending through an opening in the first mesh layer and an opening in the second mesh layer to secure a first mesh area of the mesh busbar directly to the first component; and
a second mechanical fastener extending through an opening in the second mesh layer and an opening in the second mesh layer to secure a second mesh area of the mesh busbar directly to the second component.
