Today to share the knowledge of wireless charging coil, which will also explain the working principle of wireless charging coil, if you happen to solve the problem you are now facing, don't forget to pay attention to this site, start now!
< ul>If your phone comes with wireless charging directly, simply place the back on the side of the wireless charger 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.
Wireless charging is achieved by electromagnetic induction technology. Specifically, wireless charging devices generate alternating magnetic fields at the transmitting end when the receiving end (i.e., needs to be charged)When the device enters this magnetic field range, a current will be induced inside it to achieve the charging function. Wireless charging technology mainly uses Faraday's law of electromagnetic induction.
Put the mobile phone with wireless charging function on the wireless charging board, the position should be placed, you can charge, note that some wireless charging panel supports different mobile phone models, you should choose wireless charging panel according to your mobile phone model.
Wireless charger usage: 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 baseWireless charging can be achieved, the indicator light will have a breathing effect, and it will be extinguished after 5 seconds, plug and play, convenient and quick.
How to use wireless charging To use the wireless charging function, you first need to place the mobile phone that supports wireless charging on the wireless charging board. Make sure your phone is positioned for charging to begin. The principle of wireless charging is that through an electronic receiver, the power is transmitted to a terminal device equipped with a receiver within a certain range. In this way, even if the device is not plugged into the charging cable, it can be charged.
1, the number of wireless charging coils is based on the number and size of the charging device to be charged. In theory, the more coils there are, the more efficiently the device can be charged, because the device can receive the charge at any location. However, if the number of coils is too large, it will increase the cost and volume, which is not practical or economical. Therefore, the appropriate number of coils should be selected according to different charging needs.
2, no. Each wireless charging coil will have a certain amount of energy loss, increasing the number of coils will lead to a decrease in the overall charging efficiency, more coils will increaseEnergy dissipation and mutual interference, thus reducing the efficiency of wireless charging; And increasing the number of coils requires more coils and associated circuits to be installed in the device, which increases design complexity and cost.
3, magnetic resonance charging, the principle is the same as the resonance principle of sound. Coils of the same vibration frequency arranged in a magnetic field can exchange energy with each other. If the coil is large enough, long-distance transmission is also possible, but high efficiency, miniaturization is more difficult.
1, the secondary winding is broken, the wireless charging coil has two windings, one is the main winding, one is the secondary winding, after the secondary winding is damaged, it will cause the main winding to heat, and the output has no voltage.
2, coil heating is normal. You need to increase the diameter of the copper wire. There's too much current in there. 3, in summary, wireless charging mobile phone hot is a normal phenomenon, mainly caused by the working principle of wireless charging, energy conversion efficiency, mobile phone heat dissipation design and use of the environment and other factors. When using wireless charging, buildPay attention to the heat dissipation of the mobile phone and avoid charging in a high temperature or breathable environment to ensure the safety and performance of the mobile phone.
4, the battery caused by too much current is hot, if the battery is very hot, suspend the use, otherwise there will be a risk of explosion, the high current is strictly affecting the battery, but not too high temperature, the battery life is not affected. Wireless charging will not damage the mobile phone hardware, unless the power is too high, wireless charging will not affect the life, the heat is normal when the direct charge will also heat, but overheating is not good heat dissipation or wireless charging equipment has a problem.
5, resulting in wireless mobile phoneThe root causes of charging fever are: the choice of program. This is the most fundamental reason, different solutions have their own characteristics, such as NXP, IDT, easy charge, Xxin-sun and other wireless charging solutions, whether in charging efficiency, mobile phone compatibility, or in the disconnected charge, temperature control and other aspects are different.
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. The input will communicate when the system is workingThe electricity is converted into direct current by the full bridge rectifier circuit, or the 24V direct current terminal is used to supply power to the system. 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. 2, wireless charging is also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
3, the principle of wireless charging: electromagnetic senseYes. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
4, 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, by using the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will be
