STACK HOUSING FOR BATTERY MODULES AND BATTERY SYSTEM INCLUDING THE SAME

A stack housing for battery modules includes a multi-case, an arched mount, a stack layer, and a damping bracket. The multi-case defines loading compartments that are configured to hold multiple battery modules in a divided arrangement and positioned side-by-side at a set height. The arched mount connects the loading compartments and creates a defined space. The stack layer, attached to a top of the arched mount, serves as a frame allowing battery modules to be stacked on the multi-case. The damping bracket connects ends of the stack layer and includes a downwardly bent middle portion coupled to the arched mount.
