1, magnetic charging is through the magnet male and female suction so that the charging cable and the jack can be connected to charge. In essence, it is still wired charging, but from plug-in to adsorption. This is very different from wireless charging, magnetic charging can not be charged without a line. Wireless charging is a technology that does exist, and the technology has been widely used in electronic devices.
2, the principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and mobile phone equipment installed on the two "magnetic equipment" mutualSensing and forming an electric current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
3, the scientific and technological charm behind the magnetic charging treasure comes from its unique magnetic principle. Magnetic charging uses the gravitational force of the positive and negative electrodes of the magnet, as the magic of the magnetic force, to easily achieve wireless power transmission, so that the connection between the mobile phone and the charging bank is no longer a tedious insertion and removal operation, but a natural adsorption like the magnetic force.
4, wireless charging technology is derived from radio energy transmission technology, low-power wireless charging often uses electromagnetic induction, such as the Qi method of mobile phone charging, but ZTE's electric vehicle wireless charging method uses induction, high-power wireless charging often uses resonance. The power supply device transmits energy to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
5, the working principle of magnetic charging: magnetic charging technology is mainly the use of magnet male and female to absorb to achieve the effect of charging. The design of this magnetic charger is very convenient, just connect the back of the phone withThe charger is aligned, and the magnetic force between the two causes them to automatically stick together. In this way, the user does not need to accurately align or arduously insert the cable, just put the phone gently close to the charger, and it will automatically adsorb and start charging.
6, generally seen wireless charging, the use of the "current magnetic effect" and "electromagnetic induction" principle. In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that the wire is encircled into a ring, or even wound into a coil, and the magnetic field generated will be stronger and more concentrated, which is called"Magnetic Effects of current".
There are no magnets in the wireless charger. If you place an energized wire on a magnetic compass, you can see that these currents also produce a magnetic field. If you use a moving magnet instead of an alternating current wire, you're ready. The varying currents in the wires create varying magnetic fields. The changing magnetic field creates an electric current in the other coil. The more loops you create, the stronger the effect.
Essentially, it is still wired charging, but from plug-in to adsorption. This is very different from wireless charging, magnetic charging can not be charged without a line. Wireless charging is realThe technology has been widely used in electronic equipment technology. Magnetic charging cable is also known as magnetic charging cable, magnetic charging cable, magnetic charging cable, magnetic charging cable, magnetic data cable, etc.
For smaller magnetic magnets (such as the small magnetic block on the mobile phone case, magnetic mobile phone holder, etc.) generally does not affect the function of the mobile phone. Wireless charger, mainly using inductive coupling technology, because the coupling technology is mainly through the magnetic field of the coil to generate current, the internal component of the battery itself can not constitute a magnetic field, so it will not damage the internal structure of the battery during the power-on process.
iPhoThe magnetic wireless charging of the ne 12 can be simply understood as adding a circle of magnets on the basis of the original wireless charging, and through the attraction of the magnets, the mobile phone and the wireless charger are accurately positioned and paired, thus entering a more efficient wireless charging state. Antenna system: A new antenna system has been adopted to improve 5G performance. Apple said it optimized iOS to take advantage of 5G speeds while maintaining power efficiency.
There is a strong electromagnetic field energy in the wireless charging area, and some coils are added here to induce voltage. The induced voltage can be converted into the energy received by the cell phone battery. Now, on the marketThe 2M active crystal oscillator is converted into high frequency alternating current to supply the primary winding.
2, the principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
3, wireless charging is based on the principle of electromagnetic induction and nuclear magnetic resonanceIt was done. Wireless charging technology, derived from wireless power transmission technology. Is the use of near-field induction (inductive coupling), the current flowing through the coil will produce a magnetic field. Its wireless charge transmitting end magnet application His unenergized coil near the magnetic field will generate current. Realize energy transfer.
4, the current wireless charging is more common magnetic resonance charging mode. The use of magnetic resonance technology principle, junior high school logistics textbooks have some knowledge, simply put: electricity generated magnetic, magnetic generated electricity! The magnetic field generated by the coil is then converted into electricity by the receiving coil, which is also whyThis kind of wireless charging device often comes with a thick base and a "phone case".
