Abstract

A battery pack assembly includes, among other things, a tray and a lid. The lid is secured to the tray to provide an enclosure having an interior. At least one battery module is disposed within the interior. A cross-member is disposed within the interior adjacent to at least one battery module. A touch latch secures the tray or the lid to the cross-member.

First claim

What is claimed is:

1 . A traction battery assembly, comprising:
a tray; a lid secured to the tray to provide an enclosure having an interior; at least one battery module disposed within the interior; a cross-member disposed within the interior adjacent to the at least one battery module; and a touch latch that secures the tray or the lid to the cross-member.

2 . The traction battery assembly of claim 1 , wherein the touch latch is a push-push latch.

3 . The traction battery assembly of claim 1 , wherein the touch latch is a magnetic latch.

4 . The traction battery assembly of claim 1 , wherein the touch latch is disposed entirely within the interior.

5 . The traction battery assembly of claim 1 , wherein the touch latch directly secures the lid to the cross-member.

6 . The traction battery assembly of claim 1 , wherein no portion of the touch latch extends outside the interior.

7 . The traction battery assembly of claim 1 , wherein the touch latch is configured to be transitioned between an engaged state and a disengaged state from outside the interior.

8 . The traction battery assembly of claim 1 , wherein the tray further includes a forward wall, an aft wall, and opposing side walls extending horizontally from the forward wall to the aft wall, wherein the cross-member extends along a cross-member axis between the opposing side walls of the tray.

9 . The traction battery assembly of claim 1 , wherein a plurality of fasteners secured the lid to the tray, the plurality of fasteners distributed circumferentially about a perimeter of the enclosure.

10 . The traction battery assembly of claim 1 , further comprising a first and a second portion of the touch latch, the first portion secured to the lid, the second portion secured to the cross-member, the first portion engaging the second portion when the touch latch is securing the lid to the cross-member.

11 . The traction battery assembly of claim 10 , wherein the second portion is secured to an upwardly facing surface of the cross-member.

12 . The traction battery assembly of claim 11 , wherein the first portion is a striker, wherein the second portion is an engaging detent.

13 . The traction battery assembly of claim 12 , further comprising at least one mechanical fastener that fastens to the lid to secure the first portion to the lid.

14 . The traction battery assembly of claim 13 , further comprising at least one bumper contacting the upwardly facing surface of the cross-member when the touch latch is in the engaged state.

15 . The traction battery assembly of claim 1 , wherein the touch latch comprise a hook-and-loop fastener.
