Abstract: A dual battery mobile terminal and a wireless charging system are provided. The wireless charging system includes a main battery, a secondary battery, a wireless receive module and a charging control module. The wireless receive module senses a wireless charging signal, and converts the sensed wireless charging signal into a voltage and current signal. The charging control module in turn outputs the voltage and current signal outputted from the wireless receive module to charge the main battery or the secondary battery individually, or output the voltage and current signal to charge the main battery and the secondary battery simultaneously. Thereby, the control of the dual battery charging may be achieved.

Abstract: The present disclosure discloses a wireless charging device, system, and method based on a back cover mobile power supply. The wireless charging system includes a wireless charger, a back cover mobile power supply, and an intelligent terminal. The intelligent terminal is provided with a main battery and a wireless charging device. A built-in induction coil is powered and generates an electromagnetic field when a wireless charger is powered on. The back cover mobile power supply inducts the electromagnetic field and generates a current to the wireless charging device. The intelligent terminal and the back cover mobile power supply are controlled to enter a charging state, and a charging current is transmitted to the main battery of the intelligent terminal and the back cover mobile power supply, respectively, so as to perform charging, when the current is detected by the wireless charging device.
