Today to share with you what is the meaning of the wireless charging coil knowledge, which will also explain the composition of the wireless charging coil structure, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>2, 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 is often used in the packaging of many mobile phones and wireless chargersSign for annotation. 3, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
4, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the mobile phone without wire connection.
5, the principle of mobile phone wireless charging is as follows: the electromagnetic induction charging base and the mobile phone terminal are built with coils, when the two are close, the transmission coil is based on a certain frequencyThe alternating current of the rate generates a certain current in the receiving coil of the mobile phone through electromagnetic induction, which transfers the electrical energy from the transmitting end to the receiving end, and begins to supply power to the mobile phone from the charging seat.
6, 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 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.
is a bit like that, using an induction coil. The origin of wireless charging technology is the use of wireless power transmission technology, the use of magnetic resonance in the air between the charger and the device to transfer charges, coils and capacitors form resonance between the charger and the device, to achieve efficient transmission of electric energy technology.
The principle of wireless charging technology is actually very simple, "The so-called wireless charging technology, its basic principle and the principle of the transformer, is the principle of" electricity generated magnetism, magnetic generated electricity "that we have learned in middle school physics class.
Open the phone jacket, plug the receiving module into the charging port, connect the patch to the charging port of the phone, and then put it on, remember to face up. Since energy is transmitted between the charger and the electrical device by magnetic field, twoThere is no wire connection between them, so the charger and the device that uses electricity can be exposed without conducting contacts. It is important to note that whether it is a mobile phone or a charging bank, it has a wireless function, that is, a wireless coil.
One is achieved through the principle of electromagnetic induction, and wireless charging can now be achieved on small appliances such as smart phones. 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 of the product (Micro USB port) and connect the other end to the USB port of the charging adapter.
If your phone comes directly with wireless charging, simply place the back on the side of the wireless power bank that 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.
Only mobile phones that support wireless charging can be connected to wireless power banks. Power bank pre-charge: Plug the wireless power bank into the power supply or the U of the computerSB interface for charging. During the charging process, ensure that the wireless charging bank has sufficient power 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.
Wireless charging bank charging iPhone method is as follows: iPhone already 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 plug it into the flash port of the phone.
Is there really a wireless power bank? In 2019, the answer is obviously yes, although there are not many wireless charging products in the real sense on the market, but the overall technology has been relatively mature. The principle of wireless charging treasure is also mainly wireless transmission, eliminating the entangling of wires.
