Abstract

The invention discloses a dual-battery mobile terminal and a wireless charging system thereof. The wireless charging system includes: a main battery, a secondary battery, a wireless receiving module, and a charging control module; the wireless receiving module senses wireless charging signals, and converts the sensed wireless charging signals into voltage and current signals; furthermore, the charging control module converts The voltage and current signals output by the wireless receiving module are output separately to charge the main battery / auxiliary battery, or simultaneously output to charge the main battery and the auxiliary battery. Thus, the control of charging the dual batteries is realized.
