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.

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.

A motor vehicle includes at least one battery module configured to be cooled by compressed gas. The battery module has a cooling system which has an accumulator for compressed gas that can be fed to the battery module for cooling. A control device controls supply of gas from the accumulator to the battery module in dependency of at least one output value from at least one sensor configured to measure a current output from the battery module.
