1, the principle of millet air charging technology: the core is spatial positioning and air energy transmission. The self-developed air separation charging pile has 5 built-in phase interference antennas, which can conduct millisecond spatial positioning of the mobile phone and accurately detect the location of the mobile phone. A phase control array of 144 antennas,Beam forming is used to beam millimeter waves to the phone. On the mobile side, Xiaomi has self-developed the miniaturized design of the antenna array, with built-in beacon antenna and receiving antenna array.
2, mobile phone space charging is the electromagnetic induction form of the transmitting device has a transmitting coil, the receiving device has a receiving coil, through the electromagnetic induction between the two coils of energy transmission principle is through the electromagnetic conversion, to achieve the purpose of the transmission of electricity in the space mobile phone space charging device is a wireless charging and emission program that meets the requirements of ROHS.
3, the principle of millet 11 space charging is the use of magnetic resonance wireless chargingElectrical technology. Magnetic resonance wireless charging technology is a kind of wireless charging method based on magnetic resonance principle. In the Mi 11's air separation charging technology, the charging device emits a magnetic field of a specific frequency, and the phone has a corresponding receiving coil built in.
4, and millet announced the space charging technology can charge the phone within a few meters radius, the limit of the distance between the phone and the charger is greatly reduced, charging is undoubtedly much more convenient, there is no need to deliberately put the phone on the wireless charger to charge, as far as possible to charge without influence.
5, according to the literal meaning, we can understand smallMeter's air separation charging technology is a kind of charging without any cable and any wireless charging base. It is mainly through the charging pile inside the 144 antennas to carry out the air charging system, and it is in the form of millimeter and narrow beam to transfer energy to those who need to charge the device.
6, this shows that millet's vision of wireless charging has gone beyond the traditional physical contact and has developed in a more convenient direction. It is worth mentioning that Apple's WiFi charging idea, Samsung's charging ring attempt, and the successive announcements of Xiaomi and MOTOROLA all indicate that air charging technology may become 20An important growth point of the industry in 21 years. This innovation of Xiaomi will undoubtedly push the industry into a new stage of development.
Connect the standard charger and data cable of the mobile phone to the wireless charger, and then put the mobile phone directly (vertically) or horizontally in the center position of the wireless charger base, you can realize wireless charging, the indicator light will have a breathing effect, 5 seconds later, plug and play, convenient and quick.
andOn the contrary, the current demand for wireless charging of wearable devices is very strong, and smart watches and TWS headset charging boxes are basically standard with wireless charging functions. Most of these products have limited battery capacity and are not so sensitive to charging power, even using NFC charging can be met.
Make sure your OPPO phone model supports wireless charging. You can find this information in the phone's manual or Settings menu. Place the phone in the center of the wireless charger. The logo of the wireless charger may have a special pattern or color to ensure that you have placed the phone correctly. tetsutPlug the charger into the power supply and ensure that the voltage of the power outlet is sufficient to charge the phone. Enable the wireless charging function.
When the power button of your Xiaomi phone fails, don't worry, we provide you with the following three ways to restart your phone easily. Connect the charger First, make sure your phone is fully charged. Then, connect the phone with the damaged power button to the charger. Wait a few seconds and see if the phone starts to boot. If you hold the volume up button or volume down button for a long time while connecting the charger, sometimes it can also trigger the boot.
Huawei has introduced the first hand that supports reverse wireless chargingIt allows you to easily charge your other phone or device that supports wireless charging. So, how do you set up and use this feature? Here are the secrets for you! Open the Settings First, open the Huawei mobile phone and go to the home screen of the desktop. Find the Settings option and click to enter. Turn on Battery options Find the battery options in the Settings menu, turn on and find the wireless reverse charging switch.
1, magnetic resonance wireless chargingCable : A new breakthrough in long-distance transmission magnetic field resonance technology is another way wireless charge exploration , which realizes remote transmission through resonator and magnetic field resonance. Especially in the field of electric vehicle charging wireless charging , efficiency improvement is the focus of research. As shown in Figure 4-2 Wireless charging exploration , through the resonance principle, the energy is efficiently coupled between the transmitter and the receiver in the form of a magnetic field to achieve wireless charging exploration The induction coil then converts electromagnetic waves into electricity to charge the battery.
4, the core principle of wireless charging is actually electromagnetic induction, the principle is not complicated. So far, there are two main technologies in the industry, one is the magnetic field induction technology represented by the Qi standard, and the other is the magnetic resonance technology represented by the AiRFuel standard. In principle, magnetic resonance is the better solution, it supports a longer charging distance, and can support multiple devices charging at the same time.
5, electromagnetic induction - a certain frequency of alternating current in the primary coil, through electromagnetic induction in the secondary coil
