Abstract
Disclosed is a wireless charging device, including: an oscillating module, a rectifier voltage reduction module, a power management module, and a Bluetooth communications module, wherein the Bluetooth communications module communicates with a charging socket to acquire a charging communications protocol, the oscillating module receives a signal from the charging socket and oscillates to generate AC, the rectifier voltage reduction module rectifies and reduces the voltage of the AC and then outputs a DC reference voltage, and the power management module reduces the reference voltage and then outputs a charging voltage to charge a battery.
