Huawei nova2plus wireless chargingElectrical
Need to buy wireless charger online, and need to put the phone in the specified location, as shown below.
Huawei nova4 does not have wireless charging function, because it is a mobile phone configuration is not very high, is an entry-level model, so there is no wireless charging.
There are only three Huawei wireless charging mobile phones, models are as follows: Huawei MateS. The front of Huawei MateS is equipped with a 5-inch, 1920x1080 pixel screen with a pixel density of 401ppi. Huawei Mate20pro.
Huawei Mate 20 Pro supports reverse charging technology, Mate 20 Pro can support wireless charging to otherThe smartphone acts as a "wireless charging dock" and supports up to 15W fast charge. But the Mate 20 Pro "reverse charge" is slower than ordinary wireless chargers. And limited by voltage, Mate 20 Pro must use 40W charging head to achieve 15W wireless charging; With the previous 9V output charger, it can support wireless charging up to about 10W.
In terms of core configuration, Huawei nova10 is equipped with Snapdragon 778G processor and native Hongmeng OS system. Built-in 4000mAh battery, support 65W fast charge. [Imaging] Huaweinova 10 front binocular stereo vision system, including a front 60 million ultra-wide Angle lens, with the industry's highest front 60 million, 100 degree ultra-wide Angle, 1/61 inch outsole, support 4K image quality, with excellent resolution and sensitivity.
The principle of wireless charging in the popular sense of understanding is somewhat similar to the transformer, the transformer magnetic fieldThe coupling circuit is a magnetic conductor, and the circuit of wireless charging magnetic field coupling is air, and the magnetic medium is different. Wireless charging in the industry generally has four major technologies: magnetic induction technology, magnetic resonance technology, microwave technology and electric field coupling technology. The main technologies are magnetic induction technology and magnetic resonance technology.
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. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.
Magnetic Resonance: A new breakthrough in long-distance transmission of magnetismField resonance technology is a new approach, which realizes remote transmission by resonating a resonator with a magnetic field. Especially in the field of electric vehicle charging, efficiency improvement is the focus of research. As shown in Figure 4-2, through the resonance principle, energy is efficiently coupled between the transmitter and receiver in the form of a magnetic field, achieving wireless energy transfer, even in multi-device application scenarios, and maintaining a high degree of convenience.
Wireless charging refers to the charger on 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, magical transmission of electrical energy, inductanceCoupling technology will be the bridge between charging base stations and devices. How to use: Connect the USB cable and plug it into the socket.
Principle of wireless charging The principle of wireless charging is to transfer energy to the device that needs to be charged through electromagnetic induction or electromagnetic radiation. Specifically, wireless charging is divided into two ways: electromagnetic induction and electromagnetic radiation. Electromagnetic induction: Through the principle of electromagnetic induction, the current at the transmitting end is converted into a magnetic field, and then the energy is transferred to the receiving end through the magnetic field, and then the energy is converted into current, so as to achieve wireless charging.
Radio wave type this is sentThe more mature technology, similar to the early use of ore radios, mainly consists of microwave transmitters and microwave receivers, which can capture the radio wave energy bouncing off the wall and maintain a stable DC voltage while adjusting with the load. This method requires only a transmitter mounted in a wall plug and a "mosquito" receiver that can be installed in any low-voltage product.
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 magnetic fieldThe current is fed 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.
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 connectionBridge for charging base stations and equipment.
Generally seen wireless charging, the use of the "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."
No strong radiation, no effect on the human body! The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, and electric field coupling?
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, you do not need to transfer 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.
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 on.
Place the phone on the charger so that the screen faces up. forFor best performance, place your phone in the center of the charger or as recommended by the manufacturer. The phone should make a "drip" sound after placing it on the wireless charger for a few seconds, indicating the start of charging. When charging starts, you should see the symbol "Fast Charge over Super Fast Charge" in your phone's status bar.
Electric field coupled wireless charging, the principle is to transmit power by coupling two sets of asymmetric dipoles along the vertical direction of the induced electric field generated. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that it requires a large volume of equipment and less power.
Wireless chargingThe principle of wireless charging is actually very simple, based on the familiar electromagnetic induction (the current generates a magnetic field through the electric coil, and the coil close to the magnetic field generates an induced current), so as to achieve the wireless transmission of current. Just like a transformer, the two coils are connected by a block of iron, and wireless charging turns the block of iron into air.
1, electromagnetic induction type primary coil certain frequencyThe rate of alternating current generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
2, one of the self-wound coil connected in the charging circuit, 555 output foot (third foot) with an output tube (at your own will, but to high frequency power tube) output tube link self-wound coil, will be connected to the two coils close (about 1 cm or so there is a very sufficient charging current) power can be wireless charged! The efficiency of this circuit is very low, because there is only half a wave peak high frequency so the loss is relatively large, but the principle is quite simple and easy to produce.
3, principle: the DC-DC switching power supply is divided into two parts at the high-frequency transformer, using resonant coupling; Then use RFID technology for data communication and current feedback. In a single-phase bridge rectifier circuit, if there is a filter capacitor, when the load is open, the output voltage (that is, the voltage at both ends of the capacitor) is the peak of the AC input voltage, that is, U output =414*U input, that is, the input voltage of the root 2 times.
4, what are the components of wireless charging? The left side is TX, that is, the transmitter, and the corresponding product is the wireless charging transmitter. The right side is Rx, that is, the receiving end, and the corresponding product isIt is a mobile phone with wireless charging function. TX end: MCU, power full bridge, and LC resonant Tank composed of inductors and capacitors, where the inductor is the transmitting end coil.
5, wireless charging technology is the use of electromagnetic induction principle, in the sending and receiving end with the corresponding coil to send and receive inductive current to charge.
6, the principle of electric field coupling wireless charging is to transmit electrical energy through the induced electric field generated by the coupling of two sets of asymmetric dipoles in the vertical direction. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; But the disadvantage is the need for equipment bodyLarge volume, small power. Therefore, at present, among the four wireless charging methods, electromagnetic induction wireless charging scheme is the most mature and most widely used in business.

2, the 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. The proximity of other unenergized coils to a magnetic field generates an electric current.
3, electromagnetic induction: simple and efficient intimate contact electromagnetic induction, just like a pair of tacit understanding dancers, electricityThe end and the receiving end transfer power by inductive magnetic flux. It is known for its simple structure, high efficiency and low cost, and is especially suitable for close-range device charging. However, it also has limitations, limited transmission distance and strict location requirements, requiring accurate alignment to charge, as shown in Figure 4-1.
4, electromagnetic induction primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
5, first you need to have an Apple phone that supports unlimited charging, such as the iPhone X,Then you need to buy wireless chargers from formal channels, and it is recommended to buy them from APPLE official dealers. Then power on the wireless charger, make sure there are no magnetic objects around before connecting the power. Then place it in a flat place to prevent the phone from slipping off it.
