The first is field-coupled charging. First, the handsThere are two sets of asymmetrical electric dipoles on the machine and charging device. When they are close together, they produce a coupling phenomenon and achieve the transmission of current. The transfer efficiency is good, but there are distance restrictions, and large capacity charging stations are required. The second type is magnetic resonance charging, which is different from the above electric field. This method generates electrical energy through the resonance of the same frequency magnetic field generated by the resonators at both ends.
If you use vivo mobile phone, you can refer to the following information: Wireless charging, also known as inductive charging or contactless inductive charging, based on the principle of electromagnetic induction, you do not need to transmit electricity to the device like the traditional wired charger, but will need to chargeThe device can be charged by touching the wireless charging base.
Electric field coupled wireless charging, the principle is to transmit power by coupling two sets of asymmetric dipoles along the vertical direction of the induced electric field generated. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that it requires a large volume of equipment and less power.
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 direct currentSystem power supply. 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.
1, convenience: Wireless charging of mobile phones eliminates the trouble of using charging cables. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable. Users no longer need to carry and connect specific types of chargingThe cable can be charged at any time on multiple charging stations that support wireless charging.
2, wireless charging technology still needs continuous development, at present, wireless charger is not practical, and itself is not convenient, so it needs continuous development and technical improvement.
3, mobile phone wireless charging is very convenient is not without practical significance. It is not unnecessary, wireless charging is still very convenient, such as urgent things he can let you keep full charge, when you are in front of the computer office, after using the mobile phone on the wireless charging board, you can keep full charge for it.
5, wireless charging causes environmental harm We first discuss the harm of wireless charging function, because it is very important. Wireless charging pads are inefficient, according toThe design, as well as the location of the user's phone on the charging pad, can be anywhere from 30% to 80% charging efficiency. This means that, even under ideal conditions, 20% of the electricity is wasted.
2, vivo/iQOO currently supports wireless charging devices are: X FoldiQOO 11 Pro, X90 Pro, X90 Pro, X Fold, iQOO 10 Pro, X80 Pro Snapdragon, X80 Pro Guet, X Fold, X Note, iQOO 9 Pro, X70 Pro, iQOO 8 Pro. If you have any more questions, you canEnter vivo official website -- Mobile phone really need wireless charging My -- online customer service -- slide down the bottom -- online customer service -- enter manual customer service into consultation Mobile phone really need wireless charging understand.
3, vivo mobile phone wireless charging function can be turned on by the following steps: First, ensure that vivo mobile phone supports wireless charging function. Some of vivo's older phones may not support wireless charging, so you need to first confirm whether the phone model supports wireless charging. Find the phoneClick on the Settings icon to enter the Settings interface. In the Settings screen, find the "Battery" option and tap to go to Battery Settings.
2, cable charging. In the case of the same charging time, the power of the commonly used wired battery charger is 93% after charging, and the power of the wireless charger is 88% after charging. Obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology.
3, wireless charger charging transmission distance is short, the effective transmission distance is usually within 10mm. (2) The power is relatively low, the current Qi standard stipulates that the power is 5w, 5w, 10w and 15w power, which is still too low compared with the high-power chargers such as 18w and 48w, resulting in the wireless charger charging the mobile phone slowly.
4, some Samsung mobile phones support wireless charging function, to achieve the function requires a separate charging kit, wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone.
5, very good and convenient. At present, the Apple 8 can be charged wirelessly, and wireless charging first depends on whether it is contact or non-contact. The disadvantage of contact wireless charging is also obvious, that is, the phone must be placed on a special charging pad. Prepare the accessories needed for charging, Qi wireless charger, wireless charging receiving coil. The iPhone12 can be charged wirelessly or via wired.
6, wireless charging bank does not harm the mobile phone battery. Because the working frequency of wireless charging is now below 1M, it will not affect the signal of the mobile phone. Conversely, wireless chargers are not only reducedThe use of less data cable also makes the charging method more free and safer. It is basically the same as wired charging, but the rate is lower, but the wireless charger still has a high energy conversion rate, which saves energy consumption more.
The biggest advantage of wireless charging is convenience. Wireless charging has little impact on mobile phones, but when all electronic products support wireless charging, the convenience brought to users is more interesting. appleFuture models of AirPods wireless headphones will come with AirPower-enabled charging cases, so users can charge them simply by placing them on the charging pad.
There is also the function of wireless charging is not much high-tech. This idea is very good, but the current technology may not reach our expectations, that is, unlimited charging, the actual need for data cable, but not connected to the phone, but connected to the charger, in fact, still can not get rid of wired charging, so the unlimited charging function of the phone is now not technical support, the actual use will not feelIt works.
Wireless charging requires the phone built-in charging coil and circuit, need hardware to support, if you need wireless charging mobile phone, please screen before purchase. There is also a universal wireless charging accessory, which is an external charging coil and circuit, and then the output is connected to the mobile phone charging port, so that it actually uses the original charging circuit of the mobile phone, which is absolutely universal, but the wireless charger produced by the third party is generally very small.
Slow and unsafe charging The contradiction between the heating problem during electromagnetic conversion and the unstable characteristics of lithium batteries makes the current wireless charging efficiency low10w and 15w power, compared with the wired fast charge of 18w, 48w and other high-power chargers is still too low, resulting in the wireless charger to charge the mobile phone slowly.
2, can be taken at any time, now our data cable charging is still not very convenient, wireless charging has such an advantage, take away at any time to charge, do not need to go through unplugging the data cable and plug in the data cable such links, so at this point can also be counted as an advantage. Disadvantages Mobile phone really need wireless charging : charging speed is relatively slow. When the phone is about to chargeGeneration, wireless charging is very slow. 3, although wireless charging is very convenient, but can not avoid some obvious defects, such as wireless charging needs to add a special metal coil in the back cover of the phone, which puts higher requirements on the thickness of the phone, especially those using lifting cameras or sliding screen design products do not have enough space.
