Abstract

The wireless charging device contains a mobile power member. The mobile power member contains a processor, a battery module, a temperature detection module, a magnetic detection module, an adjustable power conversion module, a wireless charging module, and a digital potentiometer. The processor is electrically connected to the battery module, the temperature detection module, the digital potentiometer, and the magnetic detection module. The digital potentiometer is electrically connected to the adjustable power conversion module. The adjustable power conversion module is electrically connected to the battery module and the wireless charging module. Through the temperature detection module'"'"'s detecting heat produced from the wireless charging module, the magnetic detection module'"'"'s detecting variation of the magnetic flux when the mobile power member charges an adjacent portable electronic appliance, together with the algorithmic calculation of the processor, the present invention achieves appropriate thermal management and saves energy consumption for the charging process.
