Basic principles of wireless charging, onThe current is converted 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.
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, generated between the coilsMagnetic fields, magical transmission of electrical energy, inductive coupling technology will become a bridge connecting charging base stations and equipment.
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 phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. As shown below.
Generally seen wireless charging, the use of "current magnetic effect.And the principle of "electromagnetic induction". 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."
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 charging is supported in mobile phones, electric vehicles, smart furniture and other fieldsProduct. 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.

Generally seen wireless charging, the use of the "current magnetic effect" and "electromagnetic induction" principle. In 1819, the Danish scientist Elster made an observationIf there is an electric current running through the wire, a magnetic field will be generated around it, which can deflect the compass needle. 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, electric field coupling and radio wave transmission, etc. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.
Wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, no needThe traditional charging power line is connected to the charger on the terminal device that needs to be charged, using the latest wireless charging technology, by using 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 the device. How to use: Connect the USB cable and plug it into the socket.
3, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the mobile phone without wire connection.
4. If your Huawei mobile phone supports wireless charging, place the mobile phone screen facing up after the wireless charger is poweredCharging can be done at the center of the device or at the location recommended by the manufacturer.
5, What is wireless charging? Wireless charging is a technology that does not require a wire connection to charge a device. It uses electromagnetic fields to transmit energy, converting electrical energy into radio waves, which are then transmitted to the device and converted into electricity to charge the device.
Wireless reverse charging refers to the mobile phone and other devices that can only receive wireless charging electromagnetic waves, can now be emitted through a wireless coilElectromagnetic waves charge other devices that support wireless charging. However, its charging power is small and can only be used as an emergency. The charging power of wireless reverse charging is not very large compared with the original charger of the mobile phone, and the speed of daily charging of large-capacity devices will be slower, which is more suitable for emergency use in emergency situations.
Simply put, your mobile phone and other devices that can only receive wireless charging electromagnetic waves can now emit electromagnetic waves through the wireless coil to charge other devices that support wireless charging. However, its charging power is small and can only be used as an emergency. The configuration path is as follows: Settings - Battery, enable wireless reverseTo the charging switch.
The meaning of wireless reverse charging is as follows: Simply put, your mobile phone and other devices that can only receive wireless charging electromagnetic waves can now emit electromagnetic waves through the wireless coil to charge other devices that support wireless charging.
Wireless reverse charging refers to a wireless charging technology. Wireless reverse charging allows devices to charge each other without the use of wires or other connections. This technology, pioneered by Apple, allows Apple devices such as the iPhone, AirPods, and Apple Watch to charge each other. Wireless reverseThe principle of charging is to use the power of the device itself to charge other devices.
