Abstract: A storage device for storing electric energy for a motor vehicle includes a storage housing that has a receiving area in which multiple storage cells for storing electric energy are received, and at least one housing part which at least partly delimits the receiving area. The housing part is reinforced by way of at least one reinforcing element formed separately from the housing part in at least one subregion. The reinforcing element has multiple separate through openings arranged at a distance from one another.

Abstract: A modular system produces design variants of a housing element for a storage housing of a storage device which has multiple storage cells that can be arranged in a receiving area of the storage housing. At least one universal housing part delimits the receiving area. A design variant-specific first reinforcing element, and a design variant-specific second reinforcing element which differs from the first reinforcing element are provided, wherein the first design variant of the housing element has the housing part and the first reinforcing element, by means of which the housing part is reinforced in the first design variant, and the second design variant of the housing element has the housing part and the second reinforcing element, by means of which the housing part is reinforced in the second design variant.

Abstract: A method is provided for self-pierce riveting which reduces a setting force required for setting the rivets. For this purpose, a clamping force produced by a clamping device is substituted by the force produced by a rivet on a punch. The clamping force varies within a known magnitude, whereas the setting force is reduced by 20%.
