Connect the phone's standard charger and data cable to the wireless charger, and then put the phone directly (vertically) or horizontally in the center position of the wireless charger base to achieve wireless chargingThe indicator light will have a breathing effect, and it will be extinguished after 5 seconds, plug and play, convenient and quick.
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.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phoneClose to the magnetic field, an electric current is generated to charge the phone. As shown below.
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 direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
The methods for charging a mobile phone (using Huawei mate40 as an example) are as follows: Operating environment: Huawei mate40, HarmonyOS0, Settings. First, we open the Settings option and click Battery. Step two, we click on wireless reverse charging. The third step, put the device that supports wireless charging on the back of the machine, you can wireless charging.
2. 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.
3. Place the charger on a horizontal surface or other location suggested by the manufacturer. Place the phone on the charger with the screen facing up. For best performance, place the phone in the center of the charger or in the location 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. Charging starts when you shouldIn the status bar of the phone, you can see the symbol of fast charge over Super fast charge.
4, you can enter the phone Settings -- battery -- more Settings -- open the "wireless reverse charging", after opening the peripherals can provide up to 10W charging power supply urgent charging. Note: After this function is enabled, if there is no charging for other devices for a long time, it will automatically turn off; This function cannot be enabled when the battery life of the phone is less than or equal to 15%.
5, 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 to be transmitted to the intelligent terminal. When the system works, the input side willCharging can be done by placing the screen facing up in the center of the charger or as recommended by the manufacturer.
3, the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is placed (vertical) or horizontal 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. two.

4, 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.
5, first of all, you need to ensure that the mobile phone is supporting wireless charging, because wireless charging requires the mobile phone built-in wireless induction coilHardware support. Connect the wireless charging board with the data cable to the charger, the general mobile phone charger can be used, the charging board will have a light prompt after the general connection, and then put the mobile phone on the charging board.
6, in practical applications, wireless charging equipment usually includes two parts: the transmitter and the receiver. The transmitter is generally a charging base that contains components such as a power supply and a transmitter coil. The receiving end is a device that needs to be charged, and contains components such as a receiving coil and a battery. When the receiving end is placed in the charging area of the transmitting end, the transmitting end will generate an alternating magnetic field, which will be connected at the receiving endInduced current in the receiving coil.
