1, frequency, received through the resonant antenna system, frequency and phase reversal. The transmitter apparently modulates its ambient field, and the receiver receives everything that satisfies the resonance condition. At the phase velocity of signal transmission, the interpretation of the resonant circuit fails. But high-frequency engineers, still using language they were familiar with, offered another explanation.
2, the power transmission coil is installed in the chargeInside the base, the receiving coil is installed in the electronics. Resonance This kind of wireless transmission method is similar to the principle of wireless communication, the electromagnetic wave of the resonant loop at the sending end is permeated in the entire space, and the resonant loop at the receiving end is at the specific frequency, so as to achieve the transmission of energy. This transmission mode can obtain higher transmission efficiency when the output power of the receiving end is relatively small.
3, the use of electromagnetic induction principle for charging equipment, the principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals to the outside, the receiving end coil receivedLine Charging function '> Which phones can wireless charging function
1. Huawei supports wireless charging models including Huawei P40Pro, Huawei P30Pro, and Huawei Mate30Pro. Huawei P40Pro supports 40W super fast charge, 27W wireless fast charge, and wireless reverse charge. Huawei P30Pro supports 40W super fast charge and 15W wireless fast charge. Huawei Mate30Pro mobile phone supports a maximum of 10V / 4A super fast charge, compatible with 4.5V / 5A or 5V / 4.5A super fast charge, compatible with 9V / 2A fast charge.
2, appleApple, Huawei, Xiaomi. Apple: The iphone supports wireless charging models are iPhoneX series, iPhone11 series, iPhone12 series, iPhone13 series, and the second generation and later versions of iPhone. These Apple phones have induction coils added to the back, and can be charged using wireless magnetic induction charging devices.
3, Huawei Mate20PRO in 2018, only Huawei Mate20 Pro has reverse wireless charging function, to know that in the past year can reachTo 15W wireless fast charge is also very remarkable. A year before Samsung, Huawei's phones support innovative wireless reverse charging technology. The 4200mAh battery can meet the long-term use, of course, also meet the hardware basis of wireless reverse fast charge, after all, how to charge others with their own small battery capacity.
4, there are many mobile phone models on the market that can be wireless charging, the common ones are: iPhone8/XR/11 series and above models support wireless charging. Huawei P30Pro/P40Pro and other high-end Pro series support wireless charging. Mat in the Mate seriese20 and above models also support wireless charging. Xiaomi Mi9/Mi10/Mi11 series flagship models have wireless charging function. RedmiK30Pro and above high-end machines are also supported.
5, if referring to vivo mobile phone, vivo/iQOO currently supports wireless charging devices are: X Fold, iQOO 10 Pro, X80 Pro Snapdragon, X80 Pro Guet, X Fold, X Note, iQOO 9 Pro, X70 Pro, iQOO 8 Pro.
6, mobile phones that support wireless charging are Honor X40 GT, iQOO Z Redmi Note 11T Pro, Redmi Note OPPO KOPPO K9x and so on. Honor X40 GT Honor X40 GT design high appearance level, equipped with racing black color, very suitable for game users. It is equipped with a Snapdragon 888 processor and 4001 square millimeter liquid-cooled VC, and the running score is as high as 810,000.
1Wireless charging, also known as inductive charging or non-contact inductive charging Wireless charging communication , based on the principle of electromagnetic induction, it does not need to transmit electricity to the device with a transmission cable like a traditional wired charger. Instead, the device that needs to be charged wireless charging communication can be charged by contacting the wireless charging base.
2, wireless charging refers to the need to connect the traditional charging power cord to the charger on the terminal device that needs to be charged, using the wireless charging communication the latest wireless chargingTechnology, by using the magnetic field generated between the coils, magical transmission of electrical energy, inductive coupling technology will become a bridge connecting charging base stations and devices. Usage Wireless charging communication : Connect the USB cable and plug it into the socket.
3, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the mobile phone without wire connection.
4. 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 onIt can be charged.
5, What is wireless charging? Wireless charging is a technology that does not require a wire connection to charge a device. It uses electromagnetic fields to transmit energy, converting electrical energy into radio waves, which are then transmitted to the device and converted into electricity to charge the device.
Wireless charging is a very practical technology that makes our lives more convenient. However, the degree of support for wireless charging by different mobile phone brands is alsoDifferent.
If referring to vivo mobile phone, vivo/iQOO currently supports wireless charging devices are: X Fold, iQOO 10 Pro, X80 Pro Snapdragon, X80 Pro Guet, X Fold, X Note, iQOO 9 Pro, X70 Pro, iQOO 8 Pro.
