The present disclosure relates to a device for wireless charging of an electrical energy store of a mobile terminal for a motor vehicle, the device including charging electronics positioned within a housing. The housing includes a support region on which to place the mobile terminal, the support region including at least two elevations, each elevation has a first predetermined height extends along a length of the support region, and is arranged in parallel at a predetermined distance from one another. When the mobile terminal is placed on the at least two elevations, an air channel is formed. The housing includes at least one air inlet opening and at least one air outlet opening configured to blow air out into the air channel. Furthermore, at least one barrier that swirls the air blown out into the air channel is arranged in the air channel.

This disclosure relates to a method for operating a ventilation device for providing an air flow. An equipment parameter value of an equipment element of a motor vehicle and a vehicle parameter value of the motor vehicle are detected. Then, the ventilation device is activated subject to the detected equipment parameter value and the detected vehicle parameter value. To activate the ventilation device, a rotational speed of a fan of the ventilation device is set, where the rotational speed is varied subject to the detected equipment parameter value and the detected vehicle parameter value.

The present disclosure relates to a charging apparatus for wirelessly charging a rechargeable electric energy store of a mobile terminal, having a housing, a primary coil device and a first control device operatively connected thereto, wherein the first control device is arranged in the housing, which has at least one air entry opening and at least one air exit opening. The housing further has a heat sink arranged in it that has an associated active air supply device, wherein the air supply device is set up to actively supply the heat sink with ambient air that can flow in, at least also through the at least one air entry opening. The heat sink has an associated temperature sensor device for sensing the temperature of the heat sink. The charging apparatus further has a second control device that has a signal connection to the temperature sensor device and is operatively coupled to the active air supply device, and that is set up to be able to activate the active air supply device as soon as and for as long as a predetermined first limit temperature of the heat sink has been reached or exceeded. Furthermore, the second control device also has a signal connection to the first control device and is set up to activate the active air supply device when the first limit temperature of the heat sink is reached or exceeded, and wireless charging of an electrical energy store of a mobile terminal is also performed.

The invention relates to a protective case apparatus for a mobile terminal, having a case base body having a baseplate region for covering a rear of the terminal. The baseplate region has an abutment area for abutting the rear of the mobile terminal. The case base body also has side walls that are integrally molded on the baseplate region and are each configured to directly abut a respective narrow side of the mobile terminal and thereby to hold the mobile terminal against the abutment area. The case base body has only three side walls and one short side of the abutment area is without a wall. When the mobile terminal is arranged in the protective case apparatus, a narrow side of the mobile terminal that is arranged on the short side is not covered by the case base body.
