Problems solved by technology

In actual use, when the power of the wireless transmitting coil and the wireless receiving coil are the same, the efficiency of wireless charging is the highest. When the power of the wireless transmitting coil and the wireless receiving coil are different from each other, the wireless charging efficiency will decrease; The charging power is different, which leads to different charging efficiency when different models of mobile phones are charged with the same wireless charger.
[0004] The wireless chargers in the prior art do not have the function of automatically adjusting the wireless charging transmission power according to the different charging power of mobile phones, and cannot adapt to mobile phones with different wireless charging powers well, and cannot make mobile phones with different wireless charging powers have the highest wireless charging power. charging efficiency

Abstract

The invention discloses a smart phone wireless charger and a charging method thereof; the method comprises the following steps that a first resonance circuit receives configuration information sent bya second resonance circuit and transmits the configuration information to a demodulation circuit; the demodulation circuit decodes the configuration information, and transmits the decoded configuration information to a first controller; the first controller controls the first resonance circuit to carry out power output, and the wireless transmitting end enters a charging state; when the smart phone to be charged is fully charged, the second resonance circuit sends charging termination information to the first resonance circuit; and the first resonance circuit transmits the charging termination information to the demodulation circuit; the demodulation circuit is used for decoding the charging termination information and transmitting the decoded charging termination information to the firstcontroller; and the first controller controls the first resonance circuit to terminate power output and enters a standby state. According to the method, the output power of the wireless transmittingend can be adjusted according to different wireless charging powers of different mobile phones, and the charging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charger for a smart phone and a charging method thereof. Background technique [0002] With the rapid development of science and technology, wireless charging technology has entered people's lives. Some electronic devices, such as mobile phones, can be charged with a wireless charger, and the mobile phone can be directly placed on the wireless charger when charging the mobile phone. [0003] Put mobile phones and other electronic devices that support wireless charging on the charging surface of the wireless charger. The wireless charger detects the wireless receiving coil in the electronic device. After the wireless transmitting coil and the wireless receiving coil of the wireless charger are matched with each other, it can start Charge. In actual use, when the power of the wireless transmitting coil and the wireless receiving coil are the same, the efficie...
