1, the loss of components affects the internal resistance of wireless charging fast and slow components, and the conversion efficiency of the system is high. The selection of components such as triode with small internal resistance can greatly improve the efficiency of wireless charging. However, with low internal resistance, the cost will be relatively high.
2, charging method connect peripheral convenience Charging efficiency Method/steps Charging method: Wireless charger first load the iPhone into the charging insuranceIn the shell, then place the protective cover on the induction base, and then the induction base is connected to the power plug, and the power plug is plugged in.
3. GND is ground. The common negative electrode. This stuff improves efficiency. One, coil material. With two-wire structure, the effective conductive area decreases due to the skin effect of high frequency conduction. Therefore, the coil can be wound with multiple strands of wire (insulation between wires). Three use low voltage drop diodes. Fourth, the electromagnetic wave is attenuated by the square of the distance, so the closer the distance, the higher the transmission efficiency.
Protocol compatibility Huawei's SuperCharge vertical wireless charger set ensures seamless connection with your own and compatible devices, and pay attention to the phone's charging protocol when selecting, such as Huawei, Apple or Xiaomi's exclusive protocol. Charging area and convenience Green Link's magnetic wireless charger, its large charging area design allows mobile phones to be placed more freely, adding convenience to your life. Make sure your choice fits your everyday usage scenario.
2, high charging efficiency Modern wireless chargers usually have fast charging function, and its charging efficiency is not inferior compared with wired charging. At the same time, wireless chargers can also adapt to different equipment needs to meet the charging needs of a variety of devices. This can be very beneficial for multi-device users.
3, wireless charging good. In wireless charging, the charger and the charged device do not need direct contact, easy to use, strong environmental adaptability, avoiding the physical interface so there will be no interface wear, sparks, leakage and other problems, in addition, wireless charging can also achieve high voltage, high current, high power chargingElectricity. The cable is charged. Wireless charging also requires a wired charger, but also more wireless charging board.
4, first of all, the wireless charger generates current through the electromagnetic field to charge the device, and its charging method may be slightly less efficient than wired charging. This means that some heat may be generated during the charging process. If exposed to a high temperature environment for a long time, the life of the battery may be affected, because high temperature is a big factor in battery performance degradation and aging.
5, you need to unplug the data cable, connection charging need to plug in the data cable again, this time the wireless charger only need to put the phonePut it on the sensor and charge it. Charging efficiency: In the case of the same charging time, the power of the commonly used wired battery charger after charging is 93%, and the power of the wireless charger after charging is 88%. Obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology.
1, convenience The main advantage of wireless chargers is their ease of use. There is no need to carry extra charging cables and plugs, just place the phone on the chargerStart charging. This is undoubtedly a huge convenience for people who travel a lot or work outside the home. Modern wireless chargers usually have a fast charging function, and their charging efficiency is not inferior to that of wired charging.
2, low charging efficiency: compared with wired charging, wireless charging efficiency is low. That means it takes longer for users to fully charge. In addition, since wireless charging requires energy conversion between transmit and receive, it may lead to reduced battery life. Slow charging speed: Due to the low efficiency of wireless charging, the charging speed is relatively slow. This makes the user needYou have to wait longer to complete the charge.
3, advantages: The advantage of wireless charger is that we can charge the phone at the same time, no longer need to unplug the data cable. In addition, it can be taken at any time, which is more convenient than charging with a data cable. At the same time, it can provide certain support for the phone, making the phone charge more stable. Disadvantages: One disadvantage of wireless chargers is that the charging speed is relatively slow, and most wireless chargers only support 5W or 5W charging power.
4, the disadvantages of wireless charging: can not play while charging: the current wireless charger is basically a wireless charger base,Without a fixed position design, it is difficult for the mobile phone to meet the needs of playing while charging. Although there are also vertical wireless chargers that can solve this problem, it will still affect normal use.
5, although wireless charging has many advantages, but in the actual use process, also found that there are many shortcomings. Compared with wired charging, wireless charging mainly has the following disadvantages. Because the magnetic field decays quickly in the air, the distance of the wireless charging technology of the mobile phone is generally very small, and the effective charging distance is generally only 3-8 mm.
6, durable: power transmission componentsNo exposure, so it will not be eroded by moisture and oxygen in the air; There is no contact, so there is no loss caused by mechanical wear and flaring during connection and separation. Convenient: there is no need to connect with wires when charging, as long as it is placed near the charger, there is no need to occupy multiple power sockets, and there is no trouble of multiple wires winding each other.
Xiaomi 10s supports wireless charging 30w, it is equipped with 4780mAh battery capacity, and supports 30W wireless flash charging 33W cableFlash charge 10W reverse charge. Xiaomi 10s mobile phone is equipped with 4780mAh large battery, giving power for a whole day, as well as high-end necessary wireless charging, full charge anytime and anywhere, 33W super wired flash charge, 56 minutes full 100%*; 30W wireless fast charge, charge and upgrade, 69 minutes full 100%*.
Demo model: Xiaomi 10s System version: MIUI Xiaomi 10s support wireless charging 30w, equipped with 4780mAh battery capacity, support 30W wireless flash charging 33W wired flash charging 10W reverse charging.
The wireless charging function of Xiaomi 10s is powerful, and the wireless flash charging speed can reach 30W, which significantly improves the convenience of daily charging. Compared with the traditional wired charging, the efficiency of wireless charging is slightly lower, but for most users, it can meet the daily needs of quick recharge. When combined with Xiaomi's official 30W wireless charger, the wireless charging performance of Xiaomi 10s can even be comparable to wired charging, and the charging efficiency is not discounted.
W. The Mi 10S is equipped with LPDDR5 memory and UFS0 flash memory, with a 4780 mah battery capacity and 30W wireless flash charge.The Mi 10S is a mobile phone released by Xiaomi on March 10, 2021.
