Title:
WIRELESS CHARGING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/159547
Kind Code:
A1
Abstract:
A wireless charging method and device. The wireless charging device (100) comprises at least two electrodes (111) arranged separately and used for contact with an electric contact of an electric power receiving device (150), and a power supply circuit that is electrically connected to the electrodes and supplies power according to association between all electrodes in contact with a conductive contact (151). The method comprises the following steps: S1: setting electrodes of a wireless charging device to a detection state; S2: detecting whether the electrodes are in contact with a conductive contact of a power receiving device; S3: determining association between all electrodes in contact with the conductive contact, and setting polarity of the electrodes respectively; and S4: connecting a power supply corresponding to the polarity according to the polarity of the electrodes. Whether an electrode is powered on and the polarity of the electrode are set by detecting the state of the conductive contact on the electrodes of the wireless charging device, and the association between the electrodes and the conductive contact can be automatically matched, so that the power supply can be completed by placing the power receiving device freely on the wireless charging device. The method and device have advantages of convenient use and ideal universality.
