Today to share the knowledge of mobile phone wireless charging coil expertise, which will also explain the mobile phone wireless charging line, if you happen to solve the problem you are now facing, don't forget to pay attention to this site, start now!
< ul>If your Huawei mobile phone supports wireless charging, place the mobile phone screen facing up in the center of the charger or the position recommended by the manufacturer after the wireless charger is powered.
This article will give you a detailed introduction to the whole process of millet 11 wireless charging, so that you can easily open the wireless charging mode. Check if your phone supports wireless charging First, open "Settings," go to "Battery and Performance," and look for the "Wireless charging" option. If you see it, sayYour Mi 11 has wireless charging powers! Choose Qi standard charger Secondly, choose a wireless charger that is in line with Qi standard.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. 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. As shown below.
Charge the phone as standardThe electrical and data cables are connected to the wireless charger, and then the mobile phone is placed directly/horizontally in the center position of the wireless charger base, wireless charging can be realized, the indicator light will have a breathing effect, and the lamp will be extinguished after 5 seconds, plug and play, convenient and quick.
First, click on [Settings] on the desktop of your phone. Next, under the Settings menu, find and click on [Battery]. Finally, open the switch button on the right side of [wireless reverse charging]. Huawei radio charging only for some mobile phones have this function, not all mobile phones have. Huawei wireless charging method: Use a data cable to connect the charging head to the charging base, and thenPlug the charging head into the power supply.
The energy transmitting coil is installed in the charging base, and the receiving coil is installed in the electronic device. Resonance This kind of wireless transmission method is similar to the principle of wireless communication, the electromagnetic wave of the resonant loop at the sending end is permeated in the entire space, and the resonant loop at the receiving end is at the specific frequency, so as to achieve the transmission of energy. This transmission mode can obtain higher transmission efficiency when the output power of the receiving end is relatively small.
1. MagneticCharging is through the magnet male and female suction so that the charging cable and the jack can be connected to charge. In essence, it is still wired charging, but from plug-in to adsorption. This is very different from wireless charging, magnetic charging can not be charged without a line. Wireless charging is a technology that does exist, and the technology has been widely used in electronic devices.
2, the principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
3, the scientific and technological charm behind the magnetic charging treasure comes from its unique magnetic principle. Magnetic charging uses the gravitational force of the positive and negative electrodes of the magnet, as the magic of the magnetic force, to easily achieve wireless power transmission, so that the connection between the mobile phone and the charging bank is no longer a tedious insertion and removal operation, but a natural adsorption like the magnetic force.
4, wireless charging technology from radio energy transmission technology, small power wireless charging often uses electromagnetic induction,See, the packaging of many mobile phones and wireless chargers is often marked with Qi labels.
Mobile phone wireless charging technology is completely without the use of wires, the use of magnets for mobile phone charging technology. Mobile phone wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transfer charge in the air between the charger and the mobile phone, coil and capacitor form resonance between the charger and the mobile phone, to achieve efficient transmission of electric energy technology.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses electricityPrinciple of magnetic 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.
Finally put the phone on the unlimited charger, note that the wireless charging induction area of the phone is generally the middle of the phone.
If you use vivo mobile phone, you can refer to the following information: Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, do not need to transfer cables like traditional wired chargersElectricity is transmitted to the device, but the device that needs to be charged can be charged by touching the wireless charging base.
The specific principle is that both ends of the wireless charging device can generate the same frequency magnetic field through the resonator to achieve the purpose of resonance generation of electric energy for mobile phone charging. From the point of view of the charging principle, in addition to the advantages of longer wireless transmission distance, there are also the advantages of convenient manufacturing of equipment. Only because this wireless charging efficiency is relatively poor, it is gradually replaced by other wireless charging methods in the mobile phone market.
