1, the mobile phone does not have this function method is as follows: you can buy a mobile phone case that supports wireless charging, and install it on the mobile phone, the advantage of this method is simple and convenient, there is no need to replace the mobile phone or disassemble the internal phone, the disadvantage is that it may increase the weight and thickness of the mobile phone, as well as affect the heat dissipation and signal of the mobile phone.
2, self-made wireless charger 1: external module installationStep Attach the module away from the MicroUSB interface. Step Connect the MicroUSB or Lightning port on the module to the phone. Steps 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. Step to select the most appropriate position, be careful not to let the part of the connection line warped phenomenon.
3. First, make sure your phone supports wireless charging. Connect the wireless charging pad and charging head through the data cable. Generally, you only need to ensure that it is above 10W. Put the phone on the charging pad, wireThe circle is usually located near the camera. There will be a prompt after charging successfully. If your Huawei mobile phone supports wireless charging, after the wireless charger is powered, directly place the mobile phone screen facing up in the center of the charger or the position suggested by the manufacturer to charge it.
1, the method of making 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 are two sides on the receiverGlue, you can attach 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.
2, 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.
3, one of the self-wound coil is connected to the charging circuit, 555 output pin (the third pin) is connected to an output tube (at will, but to high frequency powerThe output tube is linked to the self-winding coil, and the connected two coils are close to each other (about 1 cm or so will have 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.
The steps are as follows: First cut the end of the USB data cable connected to the phone with scissors or a knife, and then the long end of the data cableCut a short section at the incision, at this time you will see four green, red, white and black wires. Cut off the two green and black wires, and cut off a small section of insulation layer at the two red and green wires respectively to reveal the copper wires.
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. However, as long as you are careful to ensure that each metal shock is connected together, it can be done.
Problem 1: NoneHow to make a wire charger? There are many ways to use wireless chargers, mainly to see how the reception is installed. 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 charger refers to the use of electromagnetic wave induction principle for charging equipment, the principle is similar to a transformer.
The principle is very simple, stick the charging coil inside the phone battery cover, paste the screen wallpaper, and then put the positive and negativeSimple wireless charging , then you're ready. The varying currents in the wires create varying magnetic fields. The changing magnetic field creates an electric current in the other coil. The more loops you create, the stronger the effect. 2, wireless charging technology is a special way of power supply, it does not need the power line, relying on the propagation of electromagnetic waves, the electromagnetic wave energy into electricity, and finally achieve wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, and ZTE's electric vehicle wireless charging uses induction mode.
3, nowThe most common wireless charging method is magnetic resonance charging. The use of magnetic resonance technology principle, junior high school logistics textbooks have some knowledge, simply put is simple wireless charging : electricity generation magnetic, magnetic generation 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".
4, wireless charging technology adopts a unified industry standard, in the next few years, mobile phones, PMP/MP3 players, digital devices, mobile devices and other products can use the newLow power consumption, high compatibility with the same wireless charger. This charger resembles a tray that plugs directly into the power supply and is certified by the Alliance with ldquo; Qirdquo; Mobile phones of different brands of different companies can be charged directly on the top.
1, no, must use AC, the frequency is about 700KH.Then hold another coil close to it and it's electric. Same as the transformer. Give you an efficient wireless charging transmitter circuit if high point is required. Receive on a coil can be, if you want high efficiency, this circuit of the receiving rectifier circuit will go to the website to ask. There's a more advanced circuit diagram with identification. But most people don't get it.
Huawei Mate 30 supports wireless charging function. The standard charger supports 10V/4A or 9V/2A or 5V/2A output, the phone supports a maximum 10V/4A super fast charge, compatible with 5V/5A or 5V/5A Super fast charge, compatible with 9V/2A fast charge. The phone also supports 27W Huawei Wireless Super Fast charge and wireless reverse charging.
Hello, please charge the phone with the screen facing up in the center position of the charger or the position suggested by the charger manufacturer.
Huawei Mate 30 supports wireless charging.
