1, 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 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 the power management module output direct current through 2MThe source crystal oscillator is converted into a high frequency alternating current to supply the primary winding.
2, wireless charging system mainly uses 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 a bridge connecting the charging base station and equipment.
3, generally seen wireless charging, the use of "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."
4, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, 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 transmission coil) will generate a magnetic field, other unenergized coil (mobile phone side of the receiving coil) close to the magnetic fieldThe field generates an electric current that charges the phone. As shown below.
5, 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, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. 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.
6, the principle of wireless charging is through near-field induction, wireless charging equipment will conduct energyThe DC output after the processing module is converted into high-frequency alternating current by 2M active crystal oscillator inverter to supply the primary winding.

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."
4, there is 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.

There are three main kinds of wireless charge by what to fill : inductance, resonance andThe induction coil then converts electromagnetic waves into electricity to charge the battery.
electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the transmitting coil generates a certain current in the mobile phone receiving coil based on the alternating current of a certain frequency through electromagnetic induction, thus transferring the electrical energy from the transmitting end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
The core principle of wireless charging is actually electromagnetic induction, and the principle is not complicated. So far, there are two main technologies in the industry, one is the magnetic field induction technology represented by the Qi standard, and the other isIt is a magnetic resonance technology represented by AiRFuel standard. In principle, magnetic resonance is the better solution, it supports a longer charging distance, and can support multiple devices charging at the same time.
1, the principle of wireless charging treasure is to use wireless electromagnetic energy transmission technology to charge mobile devices. This technology works by creating a radio magnetic field between the wireless charger and the mobile device to transfer power from the wireless chargerTo the mobile device, so that the mobile device can be charged. Wireless charging bank usually consists of two parts: wireless charger and wireless charging module.
2, if your mobile phone directly with wireless charging function, just put the back on the side of the wireless charging bank can be charged. If your mobile phone does not have wireless charging function, you can plug in the mobile phone charging port through the attached ring charging sticker, and hide the module in the mobile phone case. And put it on a wireless charger. After the recognition is successful, the phone will have a "charging" reminder.
3, one is through the principle of electromagnetic induction to achieve, now can be inWireless charging on small appliances such as smartphones. According to the principle of magnetic resonance, long-distance and high-power power transmission can be theoretically achieved, and safe without radiation. Wireless mobile power charging steps: Power charging: Connect one end of the Micro USB charging cable to the DC charging interface (Micro USB interface) of the product, and connect the other end to the USB port of the charging adapter.
4, mobile phones that support wireless charging can be connected to wireless charging bank. Charging bank pre-charge: Plug the wireless charging bank into the power supply or USB port of the computer to charge. During the charging process, make sureThe power of the wireless charging bank is sufficient to avoid affecting the charging effect. Turn on wireless charging: Open the Settings in the mobile phone, click display, click to enter the column of battery and point amount, click the Settings in the upper right corner to enter the Settings page, click to turn on wireless charging.
5, wireless charging bank charging Apple phone method is as follows: Apple phone has wireless charging function, just put the back of the phone on the wireless charging bank can be wireless charging area to start charging. The iPhone does not have a built-in wireless charging function, so it needs to be achieved through the attached ring charging sticker. First, find the insertion port on the ring patch and placeIt plugs into the phone's flash port.
