Open the back cover of the smartphone, then take out the wireless charging receiver and get it ready; Or the protective layer of double-sided tape peel; The next task is to connect the receiver's metal shock to the smartphone battery, which is the most difficult part of the process. But just be careful and make sure every metal gets electrocutedJust connect it all together and it'll work.
One of the self-wound coil is connected in the charging circuit, 555 output pin (third pin) is connected to an output tube (oneself at will, but to the high-frequency power tube) the output tube is linked to the self-wound coil, and the connected two coils are close (about 1 cm or so there is a very sufficient charging current). The efficiency of this circuit is very low, because there is only half a wave peak high frequency so the loss is relatively large, but the principle is quite simple and easy to produce.
Question 1: How to make wireless charger? There are many ways to use wireless chargers, mainlySee how the reception is rigged. But no matter what the product is close, the operation method is placed on the launch plate. Take the mobile phone for example, the current mobile phone is generally added a mobile phone jacket, in this jacket there is a wireless receiver module. The phone can be charged wirelessly with this jacket.
Wireless charging technology is the use of electromagnetic induction principle, in the sending and receiving end with the corresponding coil to send and receive the induced current to charge.
The principle is very simple, stick the charging coil inside the mobile phone battery cover, paste the screen wallpaper, and then connect the positive and negative terminals to the mobile phone usbOn the power supply. You can put your phone on the Touchstone transmitter and charge it wirelessly.
Connect the charging base Connect the charger to the wireless charging base Make the wireless charging template , and then place the mobile phone or the mobile phone with the wireless charging rear case on the wireless charging base. Take off the holster If the phone's holster is too thick or not the original charging holster, it may affect the charging effect, it is recommended to take off the holster and try charging.
This article will be Wireless charging template production You detailed the whole process of millet 11 wireless charging, so that you can easily open wireless charging mode. Check if your phone supports wireless charging First, open "Settings," go to "Battery and Performance," and 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.
Connect the phone's standard charger and data cable to the wireless charger, and then put the phone in the center position of the left and right 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.
The method of wireless charging to set the mobile phone is as follows: Wireless charging sample production : Operating environment: Huawei enjoys 10s, EMUI10 system, etc. Open the Settings of your Huawei phone. Click the "Battery" option to enter. On the battery page, click the "Charging Settings" option to enter. On the Charging Settings page, turn on Wireless Reverse Charging. Finally, wireless charging can be successfully connected.
Huawei wireless charging is only available for some mobile phonesLine charging. During the charging process, ensure that the wireless charging bank has sufficient power 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.
If it is the direct back of the mobile phone with built-in wireless charging function close to the launching surface of the charging treasure, the charging treasure generally has a switch, to open. If the phone itself does not support, you need to connect an external wireless receiver. If yourThe phone is directly equipped with wireless charging function, just put the back on the side that can be charged by the wireless charging bank.
First turn on the connection Settings on your phone to enable Bluetooth or NFC. Touch the NFC area on the phone screen or select the wireless charger from the Bluetooth connection list to connect. After the connection, the wireless charging bank will automatically identify the type of mobile phone and adjust the output current according to different mobile phone models to provide the appropriate charging current for the mobile phone.
Wireless charging bank charging Apple mobile phone method is as follows: Apple mobile phone has wireless charging functionYes, 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.
The use of wireless charging bank is very simple, if your mobile phone directly with wireless charging function, just put the back on the side of the wireless charging bank can be charged automatically; If the phone does not have wireless charging function, you can also plug in the phone charging port through the attached ring charging stickerThe module is hidden in the phone case and then charged on the wireless charging bank.
The method of making a wireless charger is as follows: Attach the module to the place where the MicroUSB interface is compared. Connect the MicroUSB or Lightning port on the module to your phone. If there is double-sided tape on the receiver, you can glue it directly to the back of the phone. If it doesn't come with it, you have to figure it out yourself. Choose the most suitable position, be careful not to let the part of the connection line have the phenomenon of warping.
Soldering iron, copper wire, resistor, transistor, capacitor. That will do. So wireless charging is simple. But I suggest you don't do it yourself. It's all special materials. If you do it for fun, just make an oscillating circuit.
One of the self-wound coil is connected in the charging circuit, 555 output pin (third pin) is connected to an output tube (oneself at will, but to the high-frequency power tube) the output tube is linked to the self-wound coil, and the connected two coils are close (about 1 cm or so there is a very sufficient charging current). This circuit is very inefficient becauseFor only half the peak high frequency, the loss is relatively large, but the principle is quite simple and easy to produce.
Yes, but not too long. Too long affects the overall performance of the machine.
Thus, the point energy is transferred from the transmitting end to the receiving end, and it begins to power the phone from the charging seat because the principle is simple and easy to make, coupled with the promotion of Texas Instruments, Philips, Toshiba, Microsoft, Panasonic, Samsung, SONY, Qualcomm and other manufacturers, which is the most popular way on the market. However, wireless charging based on electromagnetic induction also has disadvantages, among which the transmission distance is severely limited.Question 6: How to do wireless charger Wireless charger is connected to the mobile phone through two coils, as long as there is a coupling current can normally charge the mobile phone. Question 7: Self-made simple wireless charger transmitterNow common is the QI solution, you can search a lot on a treasure, find the basic module, and then built into their own products.
ready-made. Charging base, charging back sticker, charging head or charging treasure, charging line, assembled, can be wireless output wireless input, still can be wired charging; Wireless charging waste electricity is certain, slow charging, low efficiency, heat, can not be separated from the base.
The wireless charger can be used Apple's universal kind, the receiver with a thin piece of cardboard directly attached to the back of the phone, the charging head into the phone's inherent charging connectorOn the mouth, add a mobile phone case or mobile phone cover is very perfect.
