The invention relates to a charging device (1) for wirelessly charging a rechargeable electric energy store of a mobile terminal device, the charging device having a housing (5), a primary coil arrangement (2) and an operation with the primary coil arrangement Connected first control device (3), wherein the first control device (3) is arranged in a housing (5) having at least one air inlet (4) and at least one air outlet (6). Also arranged in the housing ( 5 ) is a cooling body ( 8 ), which is provided with an active air supply device ( 9 ), which is designed to actively at least also pass through at least one air inlet ( 9 ). 4) The incoming ambient air is fed to the cooling body (8). The cooling body is provided with a temperature sensor device (10) for acquiring the temperature of the cooling body (8). The charging device (1) also has a second control device (11) which is in signal connection with the temperature sensor device (10) and operatively coupled to the active air supply device (9) and which sets the Thus, the active air supply device (9) can be activated as soon as and as long as a predefinable first limit temperature of the cooling body (8) is reached or exceeded. Furthermore, the second control device ( 11 ) is also in signal connection with the first control device ( 3 ) and is set such that the mobile terminal is only activated when or after the first limit temperature of the cooling body ( 8 ) is reached or exceeded. The active air input device (9) is only activated when the electric accumulator is wirelessly charged.
Description
technical field [0001] The invention relates to a charging device for wireless charging of a rechargeable electrical energy store of a mobile terminal and to a vehicle having the charging device. Background technique [0002] Devices and methods for charging electrical energy stores (accumulators, rechargeable batteries, supercapacitors, etc.) of mobile terminals, such as mobile phones, tablet computers, etc., by means of wireless energy transmission have long been known. [0003] Devices and methods for inductive energy transmission, for example according to the Qi standard, are currently the most widespread. Furthermore, devices and methods are known for wireless energy transmission by means of resonant magnetic coupling, for example according to the Rezence standard. [0004] In these two methods, an alternating magnetic field is generated by means of a plurality of primary coils, and the alternating magnetic field communicates with the one / the An alternating voltage is...
