- the charging device also has a cooling device with at least one fan, with air being able to be drawn in from the surroundings of the charging device via at least one intake duct and being used via at least one outlet duct to cool the mobile terminal that can be placed on the support area. Accordingly, the air can expediently be guided to the support area via the outlet duct in order to achieve a cooling function for the mobile terminal.

- an unimpaired air flow can be generated within the cooling channel between the cover and the rib structure.
- Such an air flow can have a laminar design and thus transport a maximum amount of heat away from the mobile terminal.
- the distance between the induction coil and the mobile terminal can preferably be a maximum of 8 mm, so that reliable transmission of the charging energy is guaranteed.
- the cover can be optimally tensioned in the support area if the cover is fastened by a one-piece or multi-part stiffening frame in the support area and is spaced apart from the rib structure in an unloaded state in a vertical direction.
- the coating can preferably be pressed in the vertical direction against the rib structure by the weight of a mobile terminal.

- the air inlet can be oriented vertically or at an angle in order, for example, to achieve optimal air intake even when the charging device is installed within a vehicle-side center console.
- At least two air inlets can also be used in order to obtain redundancy if one air inlet is covered.
- a larger air mass can be sucked into the charging device and then introduced through the at least one outlet channel onto the support surface in the region of the rib structure or into the at least one cooling channel.
- openings and, in particular, grid structures in the area of the air inlets can be formed in the frame of the receiving section. These lattice structures can be preferred may be integrated into the cover section or formed in one piece with the cover section.
- An optimal intake of cooling air can be ensured if the at least one air inlet is beveled.
- the air inlet and / or the grid structure of the air inlet can run obliquely from the outside to the inside and from the bottom to the top. This is particularly advantageous because any air inlets for sucking in the ambient air, which can be arranged in the framework of the support area, cannot be completely covered. This measure can ensure a maximum air mass flow when the charging device is in operation.
- the frame of the support area and / or the rib structure has an air outlet for guiding out air flowing out of the outlet channel.
- the frame can preferably have a blow-out opening or a blow-out grille through which the cooling air can flow into the cooling channel.

- Such an air outlet can be arranged along a narrow or a wide side of the frame of the support area.
- An air outlet introduced into the rib structure can, for example, be integrated into the ribs and / or into the plane of the rib structure.
- the air outlet can stand out from the plane in the vertical direction and guide the cooling air essentially parallel to the plane into the cooling channel.
- the heated air used to cool the mobile terminal can be diverted through those air-permeable areas of the cover that are not diverted from the mobile terminal. This can in particular be special wheel areas of the coating.
