1, wireless two-way fast charge is aA new type of charging technology, the popular wireless fast charge, can be used in a variety of scenarios, including mobile devices and electric vehicles. It can charge quickly, supports two-way transmission, and does not require the use of traditional chargers and cables. This technology is based on the principle of electromagnetic induction, by wirelessly transmitting electrical energy to the device to charge. When the internal charge of the device is full, the excess power is reversely transmitted back to the charger.
2, November 25 news, this afternoon Huawei officially released its new MatePad Pro tablet computer, Yu Chengdong in the introductionThis tablet mentioned that this tablet is the first two-way wireless charging tablet. Huawei MatePad Pro is the world's first two-way wireless charging tablet, equipped with 7250mAh large-capacity battery, support 40W super fast charge 15W forward wireless fast charge, 5W reverse wireless fast charge technology.
3, to charge the mobile phone to support fast charging, charging treasure body also supports fast charging - generally called two-way fast charging treasure. Of course, What is the meaning of the popular wireless fast charge , the premise of achieving two-way fast charge is that the mobile phone supports fast charge: charging the charging bank at the same timeThe charger can also have the corresponding power when the electricity is used. 18WPD fast charge is one of the more common. Support two-way fast charge will have a logo.
4, wireless fast charging is a combination of wireless charging technology and fast charging technology, and the mainstream models on the market now support wireless fast charging technology. Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
5, two-wayThe principle of mobile phone wireless charging in the sense is the process of converting electrical energy into magnetic field, magnetic field is transmitted through the air, and magnetic field is converted into electrical energy. The principle of wireless charging is somewhat similar to the understanding of the transformer in the popular sense, the transformer magnetic field coupling circuit is a magnetic conductor, the wireless charging magnetic field coupling circuit is air, and the magnetic medium is different. Wireless charging in the industry generally has four major technologies: magnetic induction technology, magnetic resonance technology, microwave technology and electric field coupling technology.
The first is field-coupled charging. First, there are two sets of asymmetrical electric dipoles on the phone and charging device. When they are close together, a coupling phenomenon occursTo realize 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.
At this time, the power will be converted from the transmission end to the receiving endThus 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 good resistance to metal devices I love. The second natural is to support both devices simultaneouslyCharging, this year is not only mobile phones, wireless headphone box also has many brands began to support wireless charging. Whether it is front or side face, this charger can definitely kill the vast majority of products on the market.
Wireless fast charge is actually a function, is the short for wireless charging function, but also represents the wireless charger. This charger can not be connected to the socket, very convenient. With the function of fast charging, it does not need the data cable to charge the phone directly, and only requires the user to turn the phonePut it near the wireless charger and charge it directly. The following is a detailed example to introduce this wireless charging method.
airpodS2 Wireless charging refers to the meaning that the charger and the electrical device can be connected to the earphone without wires.
is this Bluetooth headset, do not plug the data cable, through the wireless charger, you can charge it. In fact, in other words, the wireless charger, the same need to put the headset on the charger, not the real wireless charging, the same inconvenient.
2, wireless fast charging is the combination of wireless charging technology and fast charging technology, and now the main marketStream models all support wireless fast charging technology. Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
3, wireless fast charge is the use of electromagnetic induction principle, there is a coil in the sending and receiving end, the sending end of the coil connected to the wired power supply to generate electromagnetic signal, the receiving end of the coil induction of the sending end of the electromagnetic signal to generate current to charge the battery, can be simply understood as aA 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.
