1. A system, comprising at least one stationary inductive charging device for inductively charging a motor vehicle, and at least one compressor which, during operation, compresses gas, wherein:
the at least one stationary inductive charging device includes:
a base plate and a cover disposed opposite the base plate, which delimit an interior volume of the at least one stationary inductive charging device;
a coil which, during operation, provides a magnetic field;
a magnetic flux guiding unit including at least one magnetic flux guiding element for guiding the magnetic field provided via the coil;
an intermediate wall arranged between the base plate and the cover, the intermediate wall dividing the interior volume into (i) a distribution chamber defined between the base plate and the intermediate wall and (ii) a receiving chamber defined between the intermediate wall and the cover, the coil and the magnetic flux guiding unit arranged in the receiving chamber; and
an inlet fluidically connected to the distribution chamber;
the inlet is arranged on a pressure side of the at least one compressor such that the gas compressed via the at least one compressor flows along an associated flow path of the gas via the inlet into the distribution chamber;
the intermediate wall defines at least one passage fluidically connecting the distribution chamber with the receiving chamber such that the associated flow path extends via the at least one passage from the distribution chamber into the receiving chamber such that the gas flows via the at least one passage with reduced pressure into the receiving chamber; and
the at least one stationary inductive charging device further includes an outlet for letting the gas out of the receiving chamber and through which the flow path extends.
