Qi协议v1.2.3 完整版

无线充电Qi标准协议v1.2.3 Qi wireless charging is a feature available in dozens of smartphones, and many of the major smartphone makers are participating members of the WPC. For smartphones that do not yet offer wireless charging, third-party manufacturers are integrating power receiver subsystems into smartphone cases or selling charging coils that consumers can insert between the back of their smartphone and the case. Wireless charging is also appearing in a growing number of other consumer product categories—smart watches, power banks, Bluetooth headsets, cameras, electric shavers, etc. Virtually anything that uses a rechargeable battery can be designed to use Qi wireless technology. However, Qi wireless power transfer is not limited to charging batteries: it can also be used to power devices that require electric current and will remain stationary while in use, such as desktop lamps or speakers.
