The principle of wireless charging is mainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile device. The alternating current generated at the charger end will create eddy currents in the magnetic field, and the receiving coil at the mobile device end will sense this eddy currents. In this wayPower is transferred from the charger to the mobile device.
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 supply power to the system directly. 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.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the need to charge without connecting the traditional charging power cordThe charger on the terminal device adopts the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magical transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and the device.
Using the principle of electromagnetic induction charging equipment, its 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, the receiving end coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
If you use vivo mobile phone, wireless charging is also known as inductionCharging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
Electromagnetic induction wireless charging: This way of charging is to use the inductive magnetic flux generated between a wireless charging board and the induction magnet on the mobile phone, and convert this magnetic force into an electric power for current transmission.
Support wireless charging mobile phones are very many, recommend the following 5: OnePlus 10 Pro,Xiaomi Mi 12Pro, Huawei Mate XiPhone14Plus and Samsung Galaxy S22Ultra. OnePlus 10 Pro OnePlus 10 Pro is equipped with 80W wired fast charge and 50W wireless fast charge, which can quickly recharge in 32 minutes in wired mode and full charge in wireless mode in about 47 minutes, and the difference is not large compared with wired.
These mobile phones of Apple have added induction coils on the back, and can be charged using wireless magnetic induction charging devices. Huawei: Huawei wireless charging mobile phones have Mate50 series, Mate40 series, Mate30 series, Mate20 series, Mate10 series, MateRS series, P50 series, P40 series, P30 series, etc.
Mobile phones that support wireless charging are Nut R Mi MIX2S, Mi Mix Samsung S Mi 12. Nut R1 Nut R1 is a new flagship mobile phone released by Smartisan Technology in the evening of May 15, 2018 at the "Bird's Nest" of Beijing National Stadium. On November 6, 2018, Smartisan Technology held a new product conference in Chengdu and officially launched the new color of Nut R1.Peacock blue.
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.
There are many mobile phones that support wireless charging now, and the common ones are as follows: Nut R1 Nut R1 is a flagship mobile phone released by Hammer technology in May 2018, and it is also the firstSupport wireless charging hammer mobile phone. In terms of appearance, the Nut R1 uses a three-narrow border shaped full-screen design, the beauty pointed front camera fringe design, and the jaw is relatively narrow, and the screen proportion is high.
The power and efficiency of wireless charging are further strengthened in models such as the M 11. In addition, Xiaomi has also launched a number of its own brand of wireless chargers to meet the needs of different users. In addition to the above brands, OnePlus, OPPO, vivo and other mobile phone brands have also added wireless charging functions in some of their high-end models. It is foreseeable that with the continuous progress of technology and the improvement of user needs, there will be more in the future
