An exemplary battery array may include a busbar frame that includes features that facilitate the use of mechanical fastenerless connections inside the battery array. These features may include legs that can be mounted to a top cover and/or bottom cover of an array housing via an adhesive, and holders that provide an interface for connecting cell spacers to the busbar frame in order to mitigate busbar frame and/or cell spacer motion and increase the structural integrity of the battery array. Gaps between adjacent legs of the busbar frame may further establish coolant flow passages for directing a coolant around battery cells in order to thermally manage the battery array. ## Claims ### Claim 1 A battery array for a traction battery pack, comprising: an array housing; and a cell stack housed within the array housing and including a plurality of battery cells arranged between a first busbar frame and a second busbar frame, wherein each of the first busbar frame and the second busbar frame includes a first leg configured to interface with the array housing. ### Claim 2 (depends on 1) The battery array as recited in claim 1, wherein the first leg interfaces with a top cover of the array housing. ### Claim 3 (depends on 2) The battery array as recited in claim 2, comprising an adhesive disposed between a flat surface of the first leg and the top cover. ### Claim 4 (depends on 1) The battery array as recited in claim 1, wherein the first leg interfaces with a bottom cover of the array housing. ### Claim 5 (depends on 4) The battery array as recited in claim 4, comprising an adhesive disposed between a flat surface of the first leg and the bottom cover. ### Claim 6 (depends on 1) The battery array as recited in claim 1, wherein the first leg interfaces with a top cover of the array housing, and a second leg of each of the first busbar frame and the second busbar frame interfaces with a bottom cover of the array housing. ### Claim 7 (depends on 6) The battery array as recited in claim 6, comprising a first adhesive disposed between a first flat surface of the first leg and the top cover, and a second adhesive disposed between a second flat surface of the second leg and the bottom cover. ### Claim 8 (depends on 1) The battery array as recited in claim 1, wherein each of the first busbar frame and the second busbar frame includes a second leg configured to interface with the array housing, and further wherein a gap extends between the first leg and the second leg. ### Claim 9 (depends on 8) The battery array as recited in claim 8, wherein the gap establishes a coolant flow passage inside the array housing. ### Claim 10 (depends on 1) The battery array as recited in claim 1, wherein each of the first busbar frame and the second busbar frame includes a holder configured to interface with a cell spacer of the cell stack. ### Claim 11 (depends on 10) The battery array as recited in claim 10, wherein the holder is U-shaped, and further comprising an adhesive disposed between the holder and the cell spacer. ### Claim 12 (depends on 10) The battery array as recited in claim 10, wherein the holder includes a pair of flexible hook structures that are configured to engage a slot formed in the cell spacer. ### Claim 13 A battery array for a traction battery pack, comprising: an array housing; and a cell stack housed within the array housing and including a plurality of battery cells and a plurality of cell spacers arranged to extend laterally between a first busbar frame and a second busbar frame, wherein each of the first busbar frame and the second busbar frame includes a first leg configured to interface with the array housing and a first holder configured to interface with a first cell spacer of the plurality of cell spacers. ### Claim 14 (depends on 13) The battery array as recited in claim 13, wherein the first holder is U-shaped, and further comprising an adhesive disposed between the first holder and the first cell spacer. ### Claim 15 (depends on 13) The battery array as recited in claim 13, wherein the first holder includes a pair of flexible hook structures that are configured to engage a slot formed in the first cell spacer. ### Claim 16 (depends on 13) The battery array as recited in claim 13, wherein the first leg interfaces with a top cover of the array housing, and comprising an adhesive disposed between a flat surface of the first leg and the top cover. ### Claim 17 (depends on 13) The battery array as recited in claim 13, wherein the first leg interfaces with a bottom cover of the array housing, and comprising an adhesive disposed between a flat surface of the first leg and the bottom cover. ### Claim 18 (depends on 13) The battery array as recited in claim 13, wherein the first leg interfaces with a top cover of the array housing, and a second leg of each of the first busbar frame and the second busbar frame interfaces with a bottom cover of the array housing. ### Claim 19 (depends on 13) The battery array as recited in claim 13, wherein each of the first busbar frame and the second busbar frame includes a second leg configured to interface with the array housing, and further wherein a gap extends between the first leg and the second leg. ### Claim 20 (depends on 19) The battery array as recited in claim 19, wherein the gap establishes a coolant flow passage inside the array housing.
