Abstract
Battery array end plate designs are disclosed for use within traction battery packs. 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.
Claims20
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.
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.
