Retention assembly for traction battery cell array

摘要

A traction battery assembly is provided. The traction battery assembly may include an array of battery cells, a pair of endplates, a strap, and an attachment fitting. Each of the pair of endplates may be disposed on opposite ends of the array and define edges and a receiving groove extending between the edges. The strap may be sized to sit within the groove and wrap around the array and endplates. The attachment fitting may connect ends of the strap such that the endplates compress the cells. The endplates may each further define the receiving groove at a mid-region of the endplates such that the strap wraps around the array at a substantially middle portion of outer faces defined by the array.
