Abstract: A housing element is provided for a storage housing of an electrical energy store of a motor vehicle, the electrical energy store being designed to store electrical energy and having a plurality of storage cells which can be arranged in a receiving space of the storage housing and in which the electrical energy is to be stored. The housing element has a baseplate, which is formed from a light metal and is provided at least in a subregion with a reinforcing plate formed from a steel and is reinforced by virtue of the reinforcing plate being adhesively bonded to the subregion of the baseplate by an elastomer.

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 for coating a motor vehicle part includes coating and subsequently painting. In the coating, a motor vehicle bodyshell part is coated with a metallic zinc coat as cathodic corrosion protection. In the subsequent painting, the coated motor vehicle bodyshell part is painted. The motor vehicle bodyshell part is chemically polished and/or electrochemically polished prior to the coating with the metallic zinc coat.
