This article gives you a talk about the principle of wireless charging communication protocol, as well as the corresponding knowledge points of wireless charging protocol standards, I hope to help you, don't forget to collect this site. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, What is the principle of wireless charging
1, electromagnetic induction type: fundamentalThe principle is to use the principle of electromagnetic induction, similar to a transformer, the primary coil of 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. The conversion efficiency is high, the cost is cheap, but the transmission distance is short, and it is easy to be affected by the placement.
2, wireless charging principle: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generator coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, so as to transfer the point energy from the originating end to the receiving end, and then start charging from the receiving endThe seat supplies power to the phone. Magnetic resonance.
3, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field 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 direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
4, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the need to connect to the need to charge without the traditional charging power cordThe charger on the terminal device adopts 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 bridge connecting the charging base station and the 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 AC mains at the input end is converted by the full bridge rectifier circuitReason: electromagnetic induction.

Magnetic resonance.
Using the principle of electromagnetic induction charging equipment, the principle is similar to the transformer, by setting the coil at the transmitting end and the receiving end, the transmitting end coil sends an electromagnetic signal under the action of power, the receiving end coil receives the electromagnetic signal and converts the electromagnetic signal into current, so as to achieve wireless chargingThe purpose of electricity.

Huawei wireless charger supports qi protocol. Qi is the world's first standardization organization to promote Wireless charging technology - Wireless charging Alliance (Wireless Power Consortium, hereinafter referred to as the "alliance") launched the "wireless charging" standard, with convenience and versatility two major characteristics. First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger. Basic principle Qi power transmission is based on the principle of electromagnetic induction.
Support. According to Huawei's official website, Huawei supports wireless charging. Huawei has introduced a range of technologies that support wireless chargingThe phone and accessories. The latest Huawei Mate40Pro and P40Pro both have wireless charging capabilities. Users only need to place their phone on a wireless charger that supports the Qi standard to achieve a convenient wireless charging experience.
Only need to put the Huawei Mate 30 series mobile phone on the wireless charging board, the phone will automatically enter the charging mode. Huawei Mate 30 series supports Huawei's 27W wireless fast charge and is also compatible with the general Qi wireless charging protocol; When the phone starts wireless charging, the screen will display a green ring with a wireless charging symbol and the current battery charge in the middleQuantity and other information.
First of all, Huawei HONOR 80 does have wireless charging function. It supports the Qi wireless charging standard and can be charged by placing it on a wireless charger. This method is very convenient, eliminating the trouble of plugging and unplugging the charging cable, and can fully protect the phone charging port. So, how to set the wireless charging function of Huawei HONOR 80? It's pretty simple. First of all, you need to buy a wireless charger that supports the Qi wireless charging standard.
At present, most mobile phones that support wireless charging support the Qi standard. The Huawei Mate50E is no exception, it supportsWireless charging technology with Qi standard. Which wireless charging power does the Mate50E support? Wireless charging power refers to the amount of electricity received by the mobile phone through the wireless charger. At present, the wireless charger power of Qi standard is generally 5W, 5W, 10W and so on. Huawei Mate50E supports wireless charging technology with a maximum power of 50W.
The introduction of the principle of wireless charging communication protocol is here, thank you for taking the time to read the content of this site, more information about wireless charging protocol standards, wireless charging communication protocol principle don't forget to find on this site.
