Wireless charging, also known as inductive charging or non-contact inductive charging Wireless charging principle animation Based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.

The principle of wireless charging technology is "magnetic electricity", which is simply through the charging device and the mobile phoneTwo "magnetic devices" installed on the device sense each other and form an electric current. At present, there are wireless charging principle animation products that support wireless charging 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.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it does not need to transmit electricity to the device like the traditional wired charger, but will need to be chargedWireless charging principle animation , the position can not be fixed; However, the disadvantage is that the equipment is large and the power is small. Therefore, at present, among the four wireless charging methods, electromagnetic induction wireless charging scheme is the most mature and most widely used in business.
Wireless charger is actually the use of electromagnetic induction principle for charging equipment, similar to a transformer, there is a coil at both ends of the sending and receiving, the sending end of the coil connected to the wired power supply to generate electromagnetic signals, the receiving end of the coil induction of the sending end of the electromagnetic signal to generate current to the electrical equipment. As shown in the figure below, current flowing through the coil creates a magnetic field.Its wireless charging principle animation His unenergized coil will generate current when it is close to the magnetic field.
Electromagnetic induction type primary coil A certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end.
First of all, you need to have an APPLE mobile phone that supports unlimited charging, such as iPhone X, iPhone8 plus, etc. Then you need to buy wireless chargers from formal channels, and it is recommended to buy them from Apple official dealers. In turnPower on the wireless charger. Make sure there are no magnetic objects around before connecting it. Then place it in a flat place to prevent the phone from slipping off it.
First, you need to have an iPhone that supports wireless charging, such as the iPhoneX, iPhone8, iPhone8Plus, and so on. Then you need to buy wireless chargers from formal channels and recommend them to Apple's official resellers. Before connecting the power supply, power on the wireless charger and ensure that there are no magnetic objects around it. Then put it in a flat place to prevent the phone from slipping off.
The principle of wireless charging: Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed. It is important to note that whether it is a mobile phone or a charging bank, it has a wireless function, that is, a wireless coil.
2, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the mobile phone without wire connection.
3, wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the device, the device uses the received energy to charge the battery, and at the same time for its own operation.
4, wireless charging, also known as inductive charging, non-contact inductive charging, is the use of closeField induction, or inductive coupling, is the transfer of energy by the power supply device (charger) to the device that uses electricity. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.
5, finally realize wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, and ZTE's electric vehicle wireless charging uses induction mode. High-power wireless charging usually uses resonance (most electric vehicles are charged this way) to transfer energy from the power supply device (charger) to the electrical device. The device uses the received energy to charge a battery, as wellTo provide energy for the battery's own operation.
6, Wireless charging technology, this and WIFI wireless communication technology is completely different, radio waves are energetic, through some structure of the induction coil can be converted into electricity. But this kind of wireless signal used to charge is a high-frequency near-field signal, the distance is very short, can not do long-distance communication.
