Abstract: A contact device for electrically contacting at least two electrical functional components within a connection interface. The contact device includes at least one busbar which extends from a first to a second contact region. When the functional component is electrically contacted by different contact regions of the busbar, a current path can be formed within the busbar between the first and the second contact region. Each contact region has at least one contact connection lug for integral connection to an external contact surface. The electrical contacting of at least one contact connection lug with an external contact surface of one of the functional components is formed via an integral bond. The integral bond is interrupted by at least one through-opening in the contact connection lug such that at least two contact elements which exclusively have portions of the formed integral bond are formed on the contact connection lug.

Abstract: A method of performing a charging operation of an electrical energy storage system comprising charging electronics, comprising the steps: a) determining at least one charging parameter relating to the electrical energy storage system; b) transmitting the at least one charging parameter to the charging electronics of the electrical energy storage system; c) starting the charging operation as a function of the at least one charging parameter. A corresponding computer program, a machine-readable storage medium, an electronic control unit, and an electrical energy storage system are also described.

Abstract: A driver warning device which serves to warn the driver when a safety-critical condition of the vehicle is reached. A warning is issued only if such issuance is to take place in accordance with a user profile. This avoids unnecessary warnings from being issued to a driver, which could reduce the acceptance of the warning system on the part of the driver.

Abstract: A method and a device for operating a vehicle in which a plurality of vehicle functions are activatable or de-activatable. A first profile is provided, according to which a first configuration is predefined, which specifies how the individual vehicle functions are to be set. Furthermore, a second profile is provided, according to which a second configuration is predefined, which specifies how the individual vehicle functions are to be set. The setting of at least one of the vehicle functions is different in the two profiles. In a first predefined driving situation, the vehicle functions are configured according to the first profile, and in a second predefined driving situation the vehicle functions are configured according to the second profile.
