A frame structure of a battery housing for a vehicle driven by an electric motor. The frame structure is composed of individual profiled hollow-chamber sections which are designed to be at least two-chambered in the z-direction and are welded together to enclose a battery volume. The end faces of two profiled hollow-chamber sections are designed to be stepped, such that an end face portion of each of the two profiled hollow-chamber sections borders a lateral surface portion of the respective other profiled hollow-chamber section.
