Electromagnetic induction The most common way of wireless charging is to use the principle of electromagnetic induction, through the beginningThe primary and secondary coils are induced to generate an electric current, thereby transferring energy from the transmission end to the receiving end. This approach has been achieved by the Wireless Charging Alliance (Wireless? The Power? Consortium; WPC).
If the vivo mobile phone is used, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
Three contacts on the side of the X907 body provide a wireless charging connection point, which can be achieved without a specific charging caseLine charging; There is a receiving circuit in the charging protective case, which is connected with the three contacts of the mobile phone for charging. Wireless charging principle is completed by electromagnetic induction, X907 mobile phone hardware itself is no induction circuit, is through the charging protective cover (receive) and charging base (emission) to complete.
Wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
Wireless chargingThere are electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
line charging, such as Samsung S3/S4/Note2/Note3. The mobile phone itself does not support wireless charging at all, and it is necessary to install a wireless charging receiving back frame to achieve no-wire charging, such as AppleApple iPhone5/5s/6/6s etc. At present, due to the high cost of the first kind of mobile phone manufacturers, most of them are not willing to invest.
