An exemplary battery array of the traction battery pack may include features that facilitate a battery array assembly process. These features include channels for accommodating a compression fixture, interlocking features (ribs, bumps, pins, etc.) for engaging corresponding features of an array housing, and angled walls for compressing an upper portion of a cell stack during the battery array assembly process. ## 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 end plate and a second end plate, wherein each of the first end plate and the second end plate includes a channel configured to receive a compression fixture. ### Claim 2 (depends on 1) The battery array as recited in claim 1, wherein the first end plate establishes an interface between a draft angle of a wall of the array housing and the cell stack. ### Claim 3 (depends on 2) The battery array as recited in claim 2, wherein the first end plate includes a first side face that interfaces with the wall, and a second side face that interfaces with a first battery cell of the plurality of battery cells. ### Claim 4 (depends on 3) The battery array as recited in claim 3, wherein the first side face includes a first profile and the second side face includes a second, different profile. ### Claim 5 (depends on 4) The battery array as recited in claim 4, wherein the first profile is sloped or angled, and the second, different profile is flat. ### Claim 6 (depends on 3) The battery array as recited in claim 3, wherein the channel is formed in the first side face of the first end plate. ### Claim 7 (depends on 3) The battery array as recited in claim 3, wherein the first side face includes a first angled surface and a second angled surface that converge together at an apex of the first side face. ### Claim 8 (depends on 7) The battery array as recited in claim 7, wherein the channel spans across the first angled surface and the second angled surface. ### Claim 9 (depends on 3) The battery array as recited in claim 3, wherein the first side face includes a first interlocking feature that is configured to engage a second interlocking feature of the wall. ### Claim 10 (depends on 9) The battery array as recited in claim 9, wherein the first interlocking feature is a raised ledge. ### Claim 11 (depends on 9) The battery array as recited in claim 9, wherein the first interlocking feature is a rib. ### Claim 12 (depends on 9) The battery array as recited in claim 9, wherein the first interlocking feature is a dimple. ### Claim 13 (depends on 9) The battery array as recited in claim 9, wherein the first interlocking feature is a groove. ### Claim 14 (depends on 1) The battery array as recited in claim 1, wherein each of the first end plate and the second end plate includes a first interlocking feature that is configured to interlock with a second interlocking feature of a wall of the array housing. ### Claim 15 (depends on 14) The battery array as recited in claim 14, wherein the wall is part of a bottom cover of the array housing. ### Claim 16 A method for assembling a battery array, comprising: positioning a compression fixture within a channel of an end plate of a cell stack; applying a compressive force to the end plate with the compression fixture, the compressive force sufficient to compress the cell stack; positioning the cell stack within a bottom cover of an array housing; and positioning a top cover of the array housing over the cell stack. ### Claim 17 (depends on 16) The method as recited in claim 16, comprising, subsequent to positioning the cell stack within the bottom cover: removing the compression fixture from the channel. ### Claim 18 (depends on 16) The method as recited in claim 16, wherein, after positioning the cell stack within the bottom cover, a first interlocking feature of the end plate engages a second interlocking feature of the array housing to prevent the cell stack from backing out of the bottom cover. ### Claim 19 (depends on 16) The method as recited in claim 16, wherein positioning the top cover includes: compressing an upper portion of the cell stack via a contact between a sloped wall of the top cover and an angled surface of the end plate. ### Claim 20 (depends on 19) The method as recited in claim 19, wherein the channel is formed within the angled surface.
