Abstract: A charging communication system for at least one electric vehicle comprises a back end and at least one wall box, each wall box comprising a control unit with a communication unit, wherein the charging communication system comprises at least one application which is set up on at least one terminal, wherein the charging communication system is set up, via a first application, to transmit information to a first communication unit of a first wall box and to receive it from the first communication unit, wherein the first communication unit is set up to transmit the at least one piece of information received from an application to the back end.

Abstract: A high-voltage battery for a motor vehicle having at least one storage element for electrical energy, at least one control unit operating at a voltage lower than the high voltage. A modular unit including at least one switching mechanism and/or at least one fuse as electrical components, wherein the modular unit is attached in a pre-determined position to a housing, externally to this housing that holds the storage element and the control unit, in such a way that when the modular unit is plugged in on the housing, at least two high-voltage contacts of the modular unit, which are connected to at least one of the electrical components of the modular unit, are connected in an electrically conducting manner to assigned high-voltage contacts on the housing side, and at least one contact arrangement of the modular unit.

Abstract: A method for cleaning electrical contacts of an electrical switching device includes displacing a first electrical contact element and a second electrical contact element of an electrical contact relative to each other so that the first electrical contact element and the second electrical contact element are in a closed position; and when the first and second electrical contact elements are in the closed position applying a waveform on the electrical contact so that the first contact element and the second contact element are excited to undergo a mechanical vibration relative to each other.

Abstract: A plug connection for coupling a first and a second electrical connection of a first high-voltage component to a first and a second electric connection of a second high-voltage component, wherein the plug connection is provided with a housing in which is arranged as a first pair of high-volt terminals for coupling to the first and the second electric connection of the high-voltage component as well as a second pair of high-voltage terminals for coupling to the first and to the second electric connection of the second high-voltage component, wherein at least the first and the second high-voltage terminal are mounted so that they are movable relative to the second pair of connections of the plug connection in the housing.
