The invention discloses a wireless charging method and a wireless charging device. The method comprises the steps that a charging control module detects a Q value of a charging coil module in a process that the charging coil module transmits electromagnetic waves; the charging control module judges whether a metal foreign matter exists on the charging coil module or not according to the Q value of the charging coil module; if yes, the charging control module controls the charging coil module to stop sending electromagnetic waves; and if not, the charging control module controls the charging coil module to continuously send the electromagnetic waves. According to the invention, the charging control module detects the Q value of the charging coil module in the process that the charging coil module sends the electromagnetic waves, and whether the charging coil module has the metal foreign matter or not can be judged, so that charging energy loss is reduced, safety accidents caused by high temperature generated by the metal foreign matter can be effectively avoided, and the safety of wireless charging is improved.

    本发明公开了一种无线充电方法及无线充电装置,所述方法包括:所述充电控制模块在所述充电线圈模块发送电磁波的过程中,检测所述充电线圈模块的Q值;所述充电控制模块根据所述充电线圈模块的Q值判断所述充电线圈模块上是否存在金属异物;若是,则所述充电控制模块控制所述充电线圈模块停止发送电磁波;若否,则所述充电控制模块控制所述充电线圈模块继续发送电磁波。本发明通过充电控制模块在充电线圈模块发送电磁波的过程中,检测所述充电线圈模块的Q值,可判断充电线圈模块上是否存在金属异物,不仅降低了充电能量损失,而且能够有效避免因金属异物产生高温而引发的安全事故,提高了无线充电的安全性。
