Abstract

本公开公开一种无线充电方法、待充电设备及无线充电系统。该无线充电方法可应用于无线充电系统中，无线充电系统包括：待充电设备与无线充电装置；待充电设备包括：无线接收电路及电池，无线接收电路用于接收无线充电装置发射的电磁信号，并将电磁信号转换成输出电流，以为电池充电；方法包括：根据检测出的待充电设备中无线接收电路的实际输出电压值，确定在无线充电过程中待充电设备与无线充电装置之间的位置是否发生偏位；以及当待充电设备与无线充电装置之间的位置发生偏位时，将待充电设备中无线接收电路的目标输出电压值设置为实际输出电压值。该方法能够在待充电设备与无线充电装置发送偏位时保证异物检测流程的正常工作。
