1, the principle of electric field coupled wireless charging is to transmit electrical energy through the induced electric field generated by the coupling of two sets of asymmetric dipoles in the vertical direction. Suitable for short distance charging wireless charging emission separator , high conversion efficiency Wireless charging emission separator , the position can not be fixed; However, the disadvantage is that the equipment needs to be large wireless charging emission separator , and the power is small. Therefore, there are currently four kinds of wireless charging sideAmong them, the electromagnetic induction wireless charging scheme is the most mature and the most widely used in business.
2, the wireless charger is actually the use of electromagnetic induction principle for charging equipment, similar to a transformer, there is a coil at both ends of the sending and receiving, the sending end of the coil connected to the wired power supply to generate electromagnetic signals, the receiving end of the coil induction of the sending end of the electromagnetic signal to generate current to the electrical equipment. As shown in the figure below, current flowing through the coil creates a magnetic field. The proximity of other unenergized coils to a magnetic field generates an electric current.
3, electromagnetic induction Wireless charging emission separator : Simple and efficient intimate contact electromagnetic induction, just like a pair of tacit dancers, the sending end and the receiving end transfer power through the induction of magnetic flux. It is known for its simple structure, high efficiency and low cost, and is especially suitable for close-range device charging. However, it also has limitations, limited transmission distance and strict location requirements, requiring accurate alignment to charge, as shown in Figure 4-1.
4, electromagnetic induction primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
2, Xiaomi's wireless charger can be charged to Apple 11, because it is achieved through the wireless charging ring, does not need to adapt to Apple's charging interface, so Apple's mobile phone can also use other brands of wireless chargers. Not only can you charge the iPhone 11And with different charging heads can achieve slow charging or fast charging, up to 5W charging power.
3, the brand wireless charging ring is broken and the solution is as follows: Use the original charger and data cable to connect the power to charge. For the mobile phone with removable battery, you can shut down and remove the battery, use a cotton swab to clean the battery contact and the mobile phone charging interface. Bring the purchase invoice, repair card and machine to Samsung service center for inspection.
4, can hope to correct only _FC cause damage, its magnetic principle and magnetic charger is the same, because the original inside the mobile phoneThe iron is very little, the iron original is not the main original, the magnet does not have much impact on it, as long as it does not affect the use, it will not affect the performance.
5, no if the damage is not large, it does not matter. Because there's a black tape on the outside. It's not that easy to break inside. If you pry it, it'll be fine. It'll just affect the charge. It has no effect on other functions of the phone. Before use, we should check whether the structure of the coil is strong, whether the turn is loose and loose, whether the lead contact is loose, whether the magnetic core rotation is sensitive, and whether there is a slip button.
Huawei nova3 rear plug-in wireless charging cable Wireless charging emission separator The method is as follows. Remove the double-sided adhesive sticker on the back of the coil wireless charging emission separator , the contact, chip, coil three stickers are torn off wireless charging emission separator , this step needs to use tweezers, because the area of the sticker is very small, and the strength of the glue is very sufficient, it is more difficult to uncover by hand.
The Nubia Z9 supports wireless charging, so in the inner wireless charging emission separator we found a fitting charging coil with contacts. For added insulation and protection, the coil is protected by a black insulation sticker.
Glue the prepared bamboo joint with glue or hot melt glue glue coil, and then glue the paper on the hole of the bamboo joint, a USB data cable can be used.
Of course you can. There's no requirement to put foil between the phone and the charger. Plus, metalAfter the material, on the contrary, it will isolate the electromagnetic of charging, making the charging efficiency reduced.
Tear. If the wireless charger is not torn, it will affect the wireless charger can not detect the phone, and it will be hot during charging, which will cause an explosion and property damage.
