The mystery of wireless charging: The exploration of electromagnetic induction and magnetic resonance With the rapid development of science and technology, wireless charging has penetrated into our daily life, from consumer electronics to industrial equipment, and even the automotive field, it is quietly changing our use experience. This article will be in-depthThe analysis of two mainstream wireless charging technologies: electromagnetic induction and magnetic field resonance, so that wireless color material you more in-depth understanding of this convenient way of power transmission.
Now, let's explore the secrets of these two technologies! Electromagnetic induction technology is the first generation of mobile phone wireless charging representative, through the primary coil to transmit a certain frequency of alternating current, the use of electromagnetic induction in the secondary coil to generate current, wireless transmission of energy. However, this technology can only achieve single-to-single, short-distance (within 1cm) charging, power limitsWithin 5 watts, you can't achieve one-to-many charging like WiFi.
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.
The secret of wireless charging lies in electromagnetic induction: the transmitting coil of the charging base sends out a signal. The signal searches the receiving lineLoops, such as compatible smartphone receiver coils. When the receiving coil is sensed, electromagnetic induction is initiated. Electrons (current) in the transmitting coil begin to flow around the coil. This generates a magnetic field, which can be sensed by the electrons in the receiving coil. Due to the magnetic field, electrons trapped in the receiving coil begin to flow around the coil.
The car comes with wireless charging technology to make charging more convenient. With a car wireless charger, the operation process is fairly straightforward. First of all, the car wireless charger is firmly placed in the right place in the cab! Then connect the data line of the wireless charger to the cigarette lighter interface of the car, this step is the basis to ensure that the charging line is smoothNo way.
Benefits convenience: Wireless charging of mobile phones eliminates the trouble of using charging cables. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable. Users no longer need to carry and connect a specific type of charging cable, and can charge at any time on multiple charging docks that support wireless charging.

4, Demo model: MI 11 system version: MIUI 11 Slide down from the top of the phone screen to bring up the control panel, and continue to pull down to expand all the functions of "Control Center". In the Control Center screen, swipe left to the last page. Click the Edit button. Click the wireless reverse charging button. When the button turns blue, it is on.
5, the opening method of Mi 11 wireless charging is very simple: just put the phone on the wireless charger, it will automatically start charging. Mi 11 wireless charging function Mi 11Equipped with the wireless charging color material wireless charging function, which is one of its many convenient features. Wireless charging not only provides greater convenience for users, but also helps reduce the use of cables and adapters, making the charging process cleaner and more efficient.
6, Mi 11 wireless charging does not need to be opened, just use a wireless charger to charge. The specific steps are as follows: Connect the charging head to the wireless charging base using a data cable, and then plug the charging head into the power supply. Put the charging base on the table, and put the Mi 9 mobile phone on the wireless charging baseFast charging. The wireless charger is composed of a charging head, a data cable and a charging base.
Hello, please charge the phone with the screen facing up in the center position of the charger or the position recommended by the charger manufacturer.
