Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
Connect the charger (the charging head that came with the phone or was purchased separately) to the power supply. Connect the data cable Connect the charger to the wireless using the data cableThe charger. Place the phone Place the rechargeable area of the phone in the center of the upper surface of the wireless charger, and the phone shows that it is charging.
If your Huawei mobile phone supports wireless charging, place the mobile phone screen facing up in the center of the charger or the position recommended by the manufacturer after the wireless charger is powered on.
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. High-power wireless charging usually uses resonance (most electric vehicles are charged this way) to transfer energy from the power supply device (chargingTo transmit to electrical equipment. The device uses the received energy to charge the battery and at the same time provide energy for the battery's own operation.
The wireless charger must first load the mobile phone into the charging protection case, and 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. When the phone is charging on the power converter, just remove the USB from the converter and connect the peripheral to complete. Connect peripherals in the mode of wireless charging, one is to take out the phone loaded into the charging protection case, the second is to connect Mini USB, and finally Mini USWhat's the principle?
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 transmits millimeter waves to the phone through beamforming. On the mobile side, Xiaomi has self-developed the miniaturized design of the antenna array, with built-in beacon antenna and receiving antenna array.
, mobile phone space charging is the form of electromagnetic induction on the transmitting device has a transmitting coil, the receiving device has a receiving lineThe principle of transmitting energy through electromagnetic induction between two coils is to achieve the purpose of transmitting electric energy through electromagnetic conversion. The mobile phone space charging device is a wireless charging and emission scheme that meets the requirements of ROHS.
A: The role of air charging only need to place a air charging pile in the room, holding the mobile phone into the room can achieve air charging. In the space within a few meters of the radius of the air charging pile, the power of 5W can be achieved. Not only does it support charging in a static state, but you can also keep charging while holding the phone. Even if there's a foreign object between the phone and the charging station,It will not affect the air charging.
Its core technology lies in spatial positioning and energy transmission. According to the literal meaning, we can understand that millet'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.
The principle of space separation charging is to install a transmitter coil on the wireless charging base, install a receiving coil on the back of the phone, and emit when the phone is charged near the charging baseBecause the coil is connected to the alternating current, it will generate an alternating magnetic field and generate an induced current, which transfers energy from the transmitting end to the receiving end and completes the charging.
can achieve several meters of 5W charging. Not only can multiple devices be charged, but also can be charged while playing, and foreign bodies are not affected. Millet space charging technology basically meets all the needs of Qi Ji for wireless charging. Millet space charging technology not only brings true wireless charging technology, but also opens up a new space for mobile phone wireless charging technology. As this technology continues to mature, air charging technology will become the standard of future smart phones.
1, open the Settings icon on the phone, and then click battery on the Settings page to enter. Once on the page, find wireless reverse charging. Then click the button of wireless reverse charging to open, and then wireless charging can be carried out.
2, Huawei p30 The same series of Huawei p30 pro support wireless charging, EMUI system version 0 as an example, Huawei p30 pro wireless charging method is: put the wireless charger on a horizontal surface andConnect the power supply, and then place the phone screen facing up on the charger.
3, enter the battery Settings, open the wireless reverse charging switch; After the device that needs to be charged is turned on, place it in the center of the back of the device that supports wireless charging; If the charge does not start after 5 seconds, the position can be adjusted; Take away Settings that need to be charged for more than 2 minutes and the wireless reverse charge switch will automatically turn off. Tip: Do not reverse charge other Settings below 20%.
Connect the charger and data cable of the mobile phone with the wireless second charging principle Wireless second charging principle , and then put the mobile phone in the center position of the left and right of the wireless charger base, you can realize wireless charging, the indicator light will have a breathing effect, and it will be extinguished after 5 seconds. Plug and play, convenient and fast.
If your Huawei mobile phone supports wireless charging, place the mobile phone screen facing up in the center of the charger or the position recommended by the manufacturer after the wireless charger is powered on.
QuasiPrepare the accessories needed for charging, Qi wireless charger, wireless charging receiving coil. With these ready to go, we're ready to operate. Plug in the receiver coil and plug the wireless charging receiver coil into the phone port, just like you normally charge. Plug in the receiving coil. Connect the Qi wireless charging and transmitting device and then plug the charging head into the wall socket, and then connect the Qi wireless charging and transmitting device to the other end of the data cable.
Mobile phone using wireless charging Wireless second charging principle , requiredPurchase the wireless charging base or wireless charging rear case to use. Connect the charging base Connect the charger to the wireless charging base Wireless second charging principle , and then place the mobile phone or the mobile phone with the wireless charging back shell wireless second charging principle on the wireless charging base. Take off the holster If the phone's holster is too thick or not the original charging holster, it may affect the charging effect, it is recommended to take off the holster and try charging.
We turn on the phone and click Settings. On the phone's Settings screen, we tap the battery. Turn on wireless reverse chargingPower button on the right. Connect the USB charging cable to the charging plug and charger, then plug the plug into the socket. Put the phone on it can be charged normally Wireless second charging principle .
Connect the standard charger and data cable of the mobile phone to the wireless charger, and then put the mobile phone in the center position of the left and right 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.
