A battery includes a number of single cells interconnected in series and/or in parallel, the electrical poles of which for the electrical interconnection are connected to one another in a positive-fit and/or integrally bonded manner, directly or by means of cell connectors. The battery also includes a battery monitoring unit connected to the electrical poles and/or to the cell connectors in a positive-fit and/or integrally bonded manner. The electrical poles of the single cells, the cell connectors, and/or the battery monitoring unit have redundant contact areas for the positive-fit and/or integrally bonded connection. In each case only one of the contact areas which are redundant with one another is connected in a positive-fit and/or integrally bonded manner, and the further contact area(s) is/are not connected.

Battery comprising a number of individual cells connected electrically to one another and method for maintaining, repairing and/or optimizing such a battery

A method for non-releasable fixing of at least one component to a further component is provided in which a hot rivet is introduced into an opening of the at least one first component and an end face of a shank of the hot rivet is welded to a surface of the further component. Subsequently, with plastic deformation of the hot rivet, the shank of the hot rivet is compressed until a head of the hot rivet lies with a pre-stressing force at least in areas on a surface of the at least one component. The pre-stressing force, with which the head of the hot rivet lies at least in areas on the surface of the at least one component, is adjusted to a predefined value.

Method for non-releasable fixing of one component to a further component

For connecting a shaft to a rotating component, especially of a shaft to a turbine wheel of an exhaust gas turbocharger, an intermediate component is provided by means of which the shaft is connected indirectly to the rotating component. The connection between the rotating component and the intermediate component is a form-locking and/or force-locking connection, especially a riveted connection.
