The present disclosure provides a wireless communication device and a control method thereof. The wireless communication device includes a first communication control module and a second communication control module. The method includes: making the first communication control module start to work in a first mode and the second communication control module start to work in a second mode; providing, by the second communication control module, identification information; reading, by the first communication control module, the identification information, and determining whether the identification information is the same as first preset information; if so, switching both the first communication control module and the second communication control module to a third mode, and performing, by the first communication control module and the second communication control module, wireless communication to transmit data; and controlling the wireless power transmission device to perform wireless power transmission with a first preset power.

Wireless communication device and control method thereof

The present application provides a wireless power transmission device and a foreign object detection method thereof. The method includes: acquiring an input current of a transmitting unit of the wireless power transmission device and a temperature of a transmitting coil in the transmitting unit; determining a first current reference value according to the temperature of the transmitting coil; and determining a foreign object detection result according to the input current and the first current reference value corresponding to the temperature of the transmitting coil. By detecting the input current of the transmitting unit of the wireless power transmission device, it is determined whether there is a foreign object in a transmission space of the wireless power transmission device. Moreover, a temperature detection unit is added, and adjustment is made to a current threshold according to the temperature of the coil, thereby achieving more accurate foreign object detection.
