Abstract

A housing part for a multi-part housing of a battery unit may include a bottom portion and a side wall structure arranged circumferentially on the outside along the bottom portion in the circumferential direction. The side wall structure may form at least one side wall portion along the circumferential direction. The side wall portion may have an inner wall facing the bottom portion and an outer wall, which may be spaced apart from the inner wall and may face away from the bottom portion. The inner wall may be connected to the bottom portion. The inner and outer walls may be connected to one another via a framework-like cavity structure having several webs, which may be adjacent to one another in the circumferential direction and which, in the cavity structure, may form several cavities adjacent in the circumferential direction and connecting the inner wall to the outer wall.
