Today to share the knowledge of self-made tracking wireless charging, which will also explain the DIY wireless charger, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, start now!
< ul>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.
Wireless chargingThe principle of the technology is "magnetic electricity", which is simply through the charging device and the two "magnetic equipment" installed on the mobile phone device to induce each other and form a 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.
Now the wireless charging is more common magnetic resonance charging mode. The use of magnetic resonance technology principle, junior high school logistics textbooks have some knowledge, simply put: electricity generated magnetic, magnetic generated electricity!The magnetic field generated by the coil is then converted into electricity by the receiving coil, which is why this wireless charging device often carries a thick base and a "phone case".
Wireless charging technology is derived from radio energy transmission technology, low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction, high-power wireless charging often uses resonance. The power supply device transmits energy to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
Wireless charging. Then you can put the phone on the wireless charging dock to experience the wireless charging function.
First of all, we need to have a clear answer to the problem: the electromagnetic cooker is widely spread on the Internet to charge the mobile phone, indeed, someone really did it successfully!! However, the process is not by placing the mobile phone that supports wireless charging directly on the induction stove, but by making a self-made coil to generate electromagnetic induction, and after a series of depressurizing, the voltage is reduced to 2V DC voltage and then the mobile phone is charged.
ready-made. Charging base, charging back sticker, charging head or charging bank, charging cable, assembled, can be withoutWire output wireless input, can still be wired charging; Wireless charging waste electricity is certain, slow charging, low efficiency, heat, can not be separated from the base.
The steps for connecting the wireless charging bank to the mobile phone are as follows: Ensure device compatibility: Check whether the mobile phone supports wireless charging. Mobile phones that support wireless charging can only be connected to wireless power banks. 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 sure it is wirelessThe power of the charging bank is sufficient to avoid affecting the charging effect.
But there are actually two problems here. If you use wireless charging in the form of a charging bank, you only need to put the mobile phone on the wireless charging bank, and then the power switch of the charging bank to turn on the power switch, and he will directly carry out a 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. Apple mobile phone does not have built-in wireless charging function, you need to pass the attachedWith a ring charging sticker to achieve. First, find the insertion port on the ring patch and plug it into the flash port of the phone.
Prepare the accessories needed for charging, Qi wireless charger, wireless charging receiving coil. With these ready to go, we're ready to operate. Plug the wireless charging receiver coil into the phone port, just like you normally charge. Plug in the receiving coil. After the link is good, the wireless charging receiving coil is finally placed on the back of the phone, without affecting the use of the case.
The use of wireless charging bank is very simple, if your mobile phone directly with wireless charging function, just put the backThe side that can be charged on the wireless charging bank can be automatically charged; If the mobile phone does not have wireless charging function, you can also plug in the mobile phone charging port through the attached ring charging sticker, hide the module in the mobile phone case, and then charge it on the wireless charging bank.
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 the energy is transmitted between the charger and the electrical device by a magnetic field, no wires are connected between the two, so the charger and the electrical device can be exposed without conducting contacts. One thing to note is,Whether it is a mobile phone or a charging bank itself, it has a wireless function, that is, a wireless coil.
1, first, open "Settings", go to "Battery and performance", look for the "wireless charging" option. If you see it, it means that your Mi 11 has wireless charging superpowers! Choose Qi standard charger Secondly, choose a wireless charger that is in line with Qi standard. Mi 11 is compatible with many brands of Qi chargers, not only can you choose the official Xiaomi model, but also can explore more brand choicesChoice.
2, wireless charging methods are 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'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.
3. If your Huawei mobile phone supports wireless charging, place the mobile phone screen facing up in the center of the charger after the wireless charger is poweredCharging can be done by talking about the location.
4, first of all, click the "Settings" on the desktop of the phone. Next, under the Settings menu, find and click on [Battery]. Finally, open the switch button on the right side of [wireless reverse charging]. Huawei radio charging only for some mobile phones have this function, not all mobile phones have. Huawei Wireless charging method: Connect the charging head to the charging base using a data cable, and then plug the charging head into the power supply.
This is the end of the introduction of self-made tracking wireless charger and DIY wireless charger, do not know you find what you needDid you get the message? If you want to know more about this, remember to follow this site. < / p >
