The first is field-coupled charging. First, there are two sets of asymmetric indoor wireless fast charging couples on the mobile phone and charging deviceA pole. When they are close together, they produce a coupling phenomenon and achieve the transmission of current. The transfer efficiency is good, but there are distance restrictions, and large capacity charging stations are required. The second type is magnetic resonance charging, which is different from the above electric field. This method generates electrical energy through the resonance of the same frequency magnetic field generated by the resonators at both ends.
Electric field coupled wireless charging, the principle is to transmit power by coupling two sets of asymmetric dipoles along the vertical direction of the induced electric field generated. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that it requires a large volume of equipment and less power.
This time electrical energyIt will be converted from the transmission end to the receiving end, thus generating energy conversion, which is now the most common way of wireless charging. The second is magnetic resonance, which is also combined by a transmitting device and a receiving device. A frequency between the two devices needs to be tuned to the same stage, because only then can they resonate. But there is no way to commercialize this technology.
Choose this 2-in-1 wireless is nothing more than two reasons, the first is the exquisite appearance, the magnetic charging pillow and the base in the middle of the chrome-plated metal rod support, which makes the metal device good resistance to Millet 10th anniversary speech Lei always follow the millet 10 supreme commemorative edition of the product released together.

To be honest, the basic product idea of MagDart is very similar to MagSafe, but the charging speed is still beat Apple. nowIn the Android camp, whether it is wired fast charge or wireless fast charge, the competition is extremely fierce and the means are quite radical. Domestic consumers have been difficult to accept low power fast charge, MagDart's product advantages are quite obvious, and in the Android camp preemptive, playing a forerunner role. realme officials have strongly announced that on August 3, 20:00, they will debut the Android mobile phone industry's first magnetic wireless flash charging technology - MagDart - at the global Innovation technology conference. This breakthrough technology will usher in a new era of wireless flash charging in the form of magnetic magnets.
This world-renowned realme MagDart magnetic wireless flash charge is said to refresh the wireless charging speed record, and for the first time, the magnetic wireless charge is upgraded to the flash charge level, demonstrating realme's leading strength in technological innovation.
In 2021, realme also launched the world's first Android magnetic wireless charging technology MagDart. Today, realme has successfully commercialized its 150W flash charging technology in the Zhenme GT Neo3, once again proving its ability to lead the industry. In order to ensure the efficient and stable 150W flash charge, realme inZheni GT Neo3 uses a specially customized flash charge chip, taking into account the high conversion rate and low heat.
realme MagDart magnetic wireless charger has two sizes, the small model will reach 15w charging power, the big model will be higher, foreign media think it will exceed 15w. If so, then it will be the world's highest power magnetic wireless charger. However, realme has not yet supported wireless charging mobile phones, if realme officially launched this product, it should be released together with new mobile phones that support wireless charging.
Android phoneMagnetic wireless charging. According to the query of relevant information, Android phone realme officially released the Android magnetic wireless charging technology MagDart in 2021. MagDart magnetic wireless flash charging uses advanced boron-cobalt alloy strong magnets and large copper coils, which can effectively reduce the impedance and reduce the heat during wireless charging. Lower charging temperature and faster charging speed.
1, wireless fast charge is the use of electromagnetic induction principle, there is a coil in the sending and receiving end, the sending endThe coil is connected to the wired power supply to generate an electromagnetic signal, and the receiving coil senses the electromagnetic signal at the sending end to generate a current to charge the battery, which can be simply understood as a transformer without a magnetic core. Compared with wired, wireless charging has less loss to the battery, and wireless charging technology is more convenient and has lower charging heat. 2, the emergence of wireless charging technology has brought us a lot of convenience, we do not have to drag a line to walk around, only need to put the mobile phone on the table can be transmitted, its principle is a total of three kinds, divided into electromagnetic induction magnetic resonance and radio wavesStyle. Electromagnetic induction refers to the alternating current in the primary coil, which can produce a current in the secondary coil.
3, 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 why this wireless charging device often carries a thick base and a "phone case".
4, pro, etc. Wireless charging technology transmits energy by magnetic field between the charger and the electrical device, bothThere is no wire connection between them, so the charger and the device that uses electricity can be exposed without conducting contacts. The principle of fast charging of mobile phones is to increase the input value of the charging voltage or current. However, in order to truly realize fast charging of mobile phones, it also needs supporting circuits and hardware. The fast punch technology mainly includes Qualcomm's Quick Charge and Mediatek's Pump Express.
5, the principle of wireless charging is that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device converts the received energy into electrical energy, which is stored in the battery of the device. The principle of energy conduction isInductive coupling ensures no exposed conductive interface. It can not only eliminate messy transmission lines between devices, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.
6, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone。< / p >
