Traction battery packs with mixed material tray structures

Abstract

Exemplary traction battery pack designs are disclosed for use in electrified vehicles. An exemplary traction battery pack may include an outer enclosure assembly that may house one or more battery arrays and/or other battery internal components. The outer enclosure assembly may include a tray having a mixed material or “hybrid” structure that provides a space efficient design. The tray may include a first subassembly made of a first material and a second subassembly made of a second, different material. The first subassembly may include a tub, and the second subassembly may include a heat exchanger plate. Central and perimeter joint strategies may be employed for securing the second subassembly relative to the first subassembly to provide the space efficient design.
