Wireless charging, also known as inductive charging or non-contact inductive charging, 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.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become the connection of the charging base stationAnd equipment bridge.
Wireless charging technology is a special way of power supply, it does not need the power line, relying on the propagation of electromagnetic waves, the electromagnetic wave energy into electricity, and finally achieve 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.
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 type wireless charging, when the power supply of the current through the coil (wirelessThe induced magnetic flux generated between the charging pad and the magnet induced on the phone converts this magnetic force into an electric power for the transmission of current.
3, wireless charging methods include 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. As shown below.
4, mobile phone wireless chargingThe principle is to use electromagnetic induction technology to transfer electrical energy through the magnetic field in the air to the inside of the mobile phone, so as to achieve the charging of the mobile phone. Specifically, wireless charging devices mainly include two parts: transmitter and receiver. The transmitter generates a high-frequency alternating magnetic field through a built-in coil, and the coil inside the receiver receives the magnetic field energy and converts it into electricity, thus charging the phone.
5, wireless charging is also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply equipment (charger) to transmit energy to the power device,The device uses the received energy to charge the battery and at the same time for its own operation.
6, wireless charging methods include 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.
The mobile phone case will affect the wireless charging efficiency of the mobile phone. Qi wireless charging has requirements for charging distance, and the maximum charging distance is only 10 mm. This is a bit "blocking" for Chinese mobile phone users who like to use mobile phone cases, although there is no need to remove the mobile phone case, the thickness of the mobile phone case has requirements, and some charging plates are marked, and the thickness of the protective case should not exceed 3 mm. Since most smartphones that support wireless charging use Qi wireless charging standard technology.
There's a small piece of iron on the back of the phone for a wireless charger. Wireless chargers are not traditionalThe charging power cord is connected to the charger on the terminal device that needs to be charged, using the latest wireless charging technology, wireless charging technology obtained 20 patents in 2007, a variety of devices can use a charging base station, and wired charging of mobile phones, MP3 players, power tools and other power adapters will not exist.
Wireless charging. You have to have electromagnetic induction. The iron plates, of course, block the magnetic signal. That's why you can't charge it.
Socket, mobile phone plug first need a wireless charger and a data cable. However,Then insert the data cable into this hole. Then connect the other end of the charging cable to the charger head. Then plug the charging head connected to the data cable into the socket. Then take out the wireless charger for the device. Connect it to your phone and cover it. Place the phone on the tray of the wireless charger and start charging it wirelessly.
▲ Then look at the non-trace adhesive magnetic base, randomly attached two magnetic iron sheets (used to be installed in the mobile phone case), because the protective shell is also attached to the magnetic iron sheet, so these two can be used as backup. ▲ The magnetic base is presented in simple gray, which is similar to the wireless charging Q series of its own, and the back is matched with 3M strongTraceless adhesive, can carry up to 1kg weight, adhesive will not leave traces on the wall.
The iron sheet is very thin, only less than 1mm thickness, so it does not affect the feel of the hand at all; If you use a phone case, you can first attach the iron sheet to the outside of the protective case.
There are some differences in nature and use between the magnetic guide and the iron sheet. Magnetic guide is a magnetic material with strong magnetism, often used in electronic components, such as mobile phone products. It has high permeability and low permeabilityExcellent properties such as hysteresis and low loss. Iron sheet is an ordinary iron sheet, usually not very strong magnetic. Iron sheets are mainly used to manufacture the core parts of electronic components such as transformers and inductors.
is OK. First of all, it can be drawn on the iron cabinet with magnetic stickers and magnetic disks. Secondly, the magnet is a magnetic iron sheet, and the ordinary iron sheet is not magnetic. Finally, magnetic stickers, one side can be pasted on the mirror or cabinet door, and the other side has its own magnetic characteristics, which can absorb small items.
Because the magnetic phone is more convenient to use. When using the magnetic phone buckle, you need to attach an iron sheet first(also called magnet) can be used on the mobile phone, because the magnetic force of the bracket is not large enough to directly absorb the mobile phone, the magnet is similar to the anti-magnetic horn, the magnet in the speaker is installed with an iron shell to prevent magnetic dang leakage, the magnetic field of the magnet is only inside the speaker will not leak out, forming a closed magnetic field.
The wireless charging coil is located in the middle of the back of the phone. The wireless charging coil is placed inside the fuselage and is close to the back cover of the phone. So from the fuselageThe outside can not be seen, the mobile phone needs to be placed on the wireless charger when using the wireless charging function, in order to ensure the balance of the mobile phone and facilitate the user to place the mobile phone, so the wireless charging coil of all mobile phones is in the middle of the back of the mobile phone.
Users only need to place the charger on the magnet on the back of the device to start charging. Compared to traditional wireless charging methods, MagSafe enables mobile phone users around the world to enjoy a more efficient and faster charging experience without losing charging speed. Wireless charging is not only more convenient, but also protects the device itself.
