Abstract

The invention relates to a wireless charging method of a mobile terminal and a wireless charging device. The method comprises the following steps of sending a detection signal to a charging interface of the wireless charging device; judging whether a resonance response signal corresponding to the detection signal is received or not, if so, sending a charging signal to the charging interface; judging whether a charging response signal corresponding to the charging signal is received or not, if so, carrying out wireless charging to the corresponding mobile terminal; and if not, sending a pre-charging signal to the charging interface. The invention also relates to the wireless charging device. According to the wireless charging method and the wireless charging device, through a pre-charging set, an over-discharging mobile terminal can also be charged through the wireless charging device.

Description

technical field [0001] The present invention relates to the field of power management of mobile terminals, and more specifically, relates to a wireless charging method and a wireless charging device for charging a mobile terminal when the battery of the mobile terminal is over-discharged. Background technique [0002] Generally, the charging process of the battery of the mobile terminal is controlled by the power management module of the mobile terminal, and the charging process is completed through stages such as constant current charging and constant voltage charging. However, when the mobile terminal is over-used or not used for a long time (the mobile terminal will work in a low-power mode when it is not in use), the battery voltage of the mobile terminal will drop below the power-on voltage, and the power management module cannot start up. When using a wired charger to charge an over-discharged battery, an over-discharge charging circuit composed of a separate hardware...
