Mobile phone wireless charging has the advantages of convenience, flexibility, protection interface Wireless charging transmission eep, the disadvantage is low charging efficiency, slow charging speed, high cost. Benefits Convenience Wireless charging eep : Wireless charging of mobile phones eliminates the trouble of using a charging cable. The user only needs to place the phone on the charging dock Wireless charging emission eep, no need to plugUnplug the charging cable Wireless charging emit eep, you can start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable.
Wireless charging may lead to accelerated battery wear and shorten battery life. Slow charging speed Wireless charging speed is relatively slow, temporarily can not be compared with wired charging. Wireless charging requires users to hold a charging pad or use a special wireless charging seat, for frequent mobile phone users, charging while using the situation is very common, which may makeIt brings some inconvenience.
The advantages of wireless charging are: reduce loss, high adaptation rate, the disadvantages are: the distance is too small, only the transition technology Wireless charging and emission eep; The benefits of wireless charging reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply first, and then place the device that supports wireless charging on the wireless charging board.
The biggest advantage of wireless charging is convenience. Wireless charging has little impact on mobile phones, but when all electronic productsWhen wireless charging is supported, the convenience brought to the user is more interesting. Apple says future models of AirPods wireless headphones will come with AirPower-enabled charging cases, so users can charge them simply by placing them on a charging pad.
Mobile phones use wireless charging, you need to buy a wireless charging base or wireless charging back case to use. Connect the charger to the wireless charging dock, then place the phone or hand with the wireless charging back caseThe machine can be placed on the wireless charging base. Take off the holster If the phone's holster is too thick or not the original charging holster, it may affect the charging effect, it is recommended to take off the holster and try charging.
Some high-end mobile phones of Huawei can support wireless charging in addition to super wired fast charging, and wireless chargers need to be purchased separately to use wireless charging. How to use Huawei wireless charger? Connect the charger (the charging tip that came with your phone or was purchased separately) to a power source. Connect the data cable Connect the charger to the wireless charger using the data cable. Place the phone Place the rechargeable area of the phone in the center of the upper surface of the wireless charger, the phoneIt shows charging.
Place the phone on the charger Finally, place your Mi 11 on the charger, making sure the two fit tightly. If the words "Charging" appear on the screen, wireless charging is started. Don't forget, the power plug of the charger should be connected to the socket, and the distance from the phone should not be more than 5mm! Wireless charging Tips Wireless charging is convenient and fast, but it also requires attention to safety.
2, 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, by using the magnetic field generated between the coils, the magic transmission of electrical energy, inductanceCoupling technology will be the bridge between charging base stations and devices. 3, wireless charging is 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.
4, 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, wireless support has appeared in mobile phones, electric vehicles, smart furniture and other fieldsCharging the product. 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.
5, the principle of wireless charging of mobile phones in the general sense is the process of converting electrical energy into magnetic field, magnetic field is transmitted through the air, and magnetic field is converted into electrical energy. The principle of wireless charging is somewhat similar to the understanding of the transformer in the popular sense, the transformer magnetic field coupling circuit is a magnetic conductor, the wireless charging magnetic field coupling circuit is air, and the magnetic medium is different. Wireless charging in the industry generally has four major technologies: magnetic induction technology and magnetic resonance technologyTechnology, microwave technology and electric field coupling technology.
1, the basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and 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 direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
2, wireless chargingThe electric 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 a bridge connecting the charging base station and equipment.
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 power supply of the current through the coil (wireless charger wireThe coil) will generate a magnetic field, and the other unenergized coil (the electric coil on the phone side) will generate a current near the magnetic field, charging the phone. As shown below.
4, generally seen wireless charging, the use of "current magnetic effect" and "electromagnetic induction" principle. In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that the wire is encircled into a ring, or even wound into a coil, and the magnetic field generated will be stronger and more concentrated, which is called the "current magnetic effect."

After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.

4, there is no strong radiation, no effect on the human body! The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc., wireless charging of mobile phones is mostly adoptedIt uses the principle of electromagnetic induction.

6, hello, wireless charging is the use of electromagnetic induction principle, the charging device is equipped with electromagnetic induction coil, the charging device is also equipped with electromagnetic coil.
