Title:
WIRELESS CHARGING CIRCUIT, WIRELESS CHARGING METHOD, WIRELESS CHARGING SYSTEM AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/024694
Kind Code:
A1
Abstract:
The present disclosure provides a wireless charging circuit, a wireless charging method, a wireless charging system and a mobile terminal. The wireless charging circuit comprises: an acquisition unit for acquiring voltage information of a battery in a mobile terminal; a charging control unit for obtaining the voltage information of the battery, and determining, according to the voltage information, current information of the battery during charging; a first communication unit for sending the voltage information and current information of the battery to an external wireless charging device; a receiving unit for generating a direct current charging current generated by sensing an electric signal generated by the external wireless charging device according to the voltage information and current information of the battery; and a switch unit for inputting, in a conductive state, the direct current charging current to the battery by means of the acquisition unit.
