Mobile phone wireless charging refers to the connection between the charger and the electrical device without wiresYou can charge your phone.
Wireless charging, 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 device (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.
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 that uses electricity. If the distance between the charger and the electrical device is relatively largeFar, it is necessary to use resonant inductive coupling design.
Wireless charging is a convenient charging technology. Wireless charging realizes the function of charging electronic devices without data line connection through the principle of electromagnetic induction. It is based on the magnetic field between the charging base or charging pad and the device, and transfers power wirelessly to the device's battery. This technology uses special induction coils and corresponding power management chips to ensure a safe and efficient charging process.
Wireless charging refers to the technology of providing electrical energy to electronic devices through wireless technology. Wireless charging mainly relies on wireless induction technology to achieve energyThe amount of transmission. With the rapid development of electronic technology, the traditional wired charging method has gradually failed to meet the needs of users due to its problems such as inconvenient insertion and removal and limited device location. The emergence of wireless charging technology has solved these problems.
1, the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is placed (vertical) or horizontally 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.
2, put the mobile phone with the wireless charging protocol on the wireless charger to wireless charging. Wireless charging precautions: When wireless charging, pay attention to the location of the mobile phone and wireless charger to prevent the mobile phone from sliding off the wireless charger and causing charging to be unable to proceed. If the mobile phone has serious fever during wireless charging, the wireless charging should be stopped to prevent the rapid decline of the mobile phone battery capacity in this state.
3, first click the "Settings" option on the desktop of the phone. Then in the Settings page that opens, click on the "Battery" option. Last on the battery pageTurn on the "wireless reverse charging switch".
2, wireless charging technology is a special way of power supply, it does not need a power cord, rely on electricityThe propagation of magnetic waves converts electromagnetic wave energy into electrical energy, and finally realizes 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.
3, wireless charging system mainly uses 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 a bridge connecting the charging base station and equipment.
Mobile phone wireless charging Because there is no need to plug and unplug the charging cable frequently, the data interface wear of the mobile phone will be reduced a lot. At the same time, the coil of wireless charging of the mobile phone is not exposed to the air, which can also reduce the oxidative corrosion of the charging unit. The wired charging is often inserted and removed easily lead to wear, and the interface is exposed, which is easy to oxidation corrosion. Although wireless charging has many advantages, it is also found that there are many disadvantages in the actual use process.
Benefit one: Reduce wear and tear. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply first, and then use the powerThe device with wireless charging can be placed on the wireless charging pad. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method. Benefit 2: high adaptation rate.
Advantages: The advantage of wireless charger is that we can charge the phone at the same time, no longer need to unplug the data cable. In addition, it can be taken at any time, which is more convenient than charging with a data cable. At the same time, it can provide certain support for the phone, making the phone charge more stable. Cons: One drawback of wireless chargers is the speed of chargingThe degree is relatively slow, and most wireless chargers only support 5W or 5W charging power.
Disadvantages of wireless charging: can not charge while playing: the current wireless charger is basically a wireless charger base, there is no fixed position design, mobile phones are difficult to meet the needs of charging while playing. Although there are also vertical wireless chargers that can solve this problem, it will still affect normal use.
Disadvantages of wireless chargers: Charging speed may be limited Although many wireless chargers have achieved fast charging, in some cases, their charging speed may still not be as fast as traditional wired charging methods. Especially in electricityWhen the amount is low, in the case of fast charging, wireless charging may not meet the needs of users. Higher cost Compared to wired chargers, wireless chargers are usually more expensive.
High technical content, easy to operate, can implement relatively long distance radio energy conversion. Disadvantages of wireless charging: Although the technical content of the equipment is high, the economic cost of the equipment is high and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.
Wireless charging principle is mainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. When a charger is produced between a mobile deviceWhen a magnetic field is generated, electromagnetic induction is generated. The alternating current generated at the charger end will create eddy currents in the magnetic field, and the receiving coil at the mobile device end will sense this eddy currents. In this way, power is transferred from the charger to the mobile device.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output DC is converted into high-frequency AC by 2M active crystal inverterCurrent is supplied to the primary winding.
Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
Wireless charging, 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 device (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.
