Principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the coil is generated based on a certain frequency of alternating current through electromagnetic induction in the mobile phone receiving coilA certain current is generated, which transfers the point energy from the originating end to the receiving end, and begins to power the phone from the charging seat. Magnetic resonance.
Wireless charging principle is mainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile device. 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.
Wireless charging system mainThe principle of electromagnetic induction should be adopted. 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.
Wireless charging mainly uses electromagnetic induction, magnetic field resonance, radio waves, electric field coupling and other principles. Wireless charging Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
2, 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 converted into a current transmissionTo the smart 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.

1. After powering the wireless charger, place the phone screen facing up directly in the center of the charger or the position suggested by the manufacturer to charge.
2, first click the "Settings" option on the desktop of the phone. Then in the Settings page that opens, click on the "Battery" option. Finally, in the battery page, open the "wireless reverse charging switch".
3, first of all, click the "Settings" on the desktop of the phone. Next, in SettingsUnder the menu, find and click on [Battery]. Finally, open the switch button on the right side of [wireless reverse charging]. The Huawei Mate30 Pro, a smartphone owned by Huawei, was unveiled in Munich, Germany, on September 19, 2019.
4. Turn on wireless reverse charging in the Settings of Huawei mobile phone to enable the wireless charging function. The specific operations are as follows: 1 Turn on the Settings. 2 Find the battery Locate the battery options on the Settings screen.
5, where is the wireless charging function of Huawei mobile phone Demo model: Huawei MatHonor mobile desktop click "Settings" option. On the Settings page that opens, click the "Battery" option. On the battery page, turn on the "Wireless reverse charge switch".
3, wireless charging only need to put the phone on the wireless charging base. Huawei Honor mobile phone can follow the following steps to open the wireless charging hidden function: First, we open the Settings on Huawei Honor mobile phone, then we click to enter the battery, then we click more Settings on the page, after entering the page, then click wireless reverse charging, and then click to open the wireless reverse charging button.
4, firstStart by tapping the "Settings" option on your phone's desktop. Then in the Settings page that opens, click on the "Battery" option. Finally, in the battery page, open the "wireless reverse charging switch". The benefits of wireless charging of mobile phones do not need to plug and unplug, convenient and fast. Just place the phone on the charger and you can start charging it without worrying about finding the cable or plug. At the same time, it can protect the phone interface and extend the service life.
5, System: Android 10 First open the desktop of the phone, enter the 【 Service 】 menu. Click My at the bottom right and select My Device. Click Select [View device parametersTo continue with the next step. Select the "Fast charge" option to check whether the current phone supports wireless charging. After confirming, put the phone in the [wireless charger] and display the [charging tips].
