This article to talk about wireless charging is chicken ribs, and wireless charging is good? Corresponding knowledge points, I hope to help you, don't forget to collect this site oh. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Isn't wireless charging a bit lame?
Wireless charging is not a chicken rib, but a very useful charger. For people at work, they do not have time to repeatedly plug in the charger, only occasionally check whether there is a text message or phone call. With wireless charging, you can better protect the interface of the phone, and you can also have power anytime and anywhere. They don't worry about what to do when they go out without electricity,Just place it where it's charging.
The charge efficiency is not high. Once the distance is a little far away, the efficiency of charging will be dramatically reduced, and a lot of time and resources need to be wasted to complete the charging, so the use is not meaningful. Safety issues in the charging process. High-power wireless charging equipment will produce a large amount of electromagnetic radiation, which will cause certain adverse effects on health, but also have interference effects on aircraft and communications. The first practical aspect.
Because many people think that this function is relatively weak. Now unlimited charging is more troublesome than charging with a data cable. Although wirelessCharging sounds very tall, but the actual operation is not convenient, many unlimited chargers themselves are very heavy, the volume is also large, it is not convenient to carry. I reviewed an unlimited charger at work and never wanted to buy one again because it didn't feel good at all.
Really can only be a gimmick! All mobile phones must be placed on the device for wireless charging, are rogue! The point is that you also need to buy wireless charging devices.
The main reason why users don't like wireless charging is that the current QI wireless charging is electromagneticShould technology, although the step of plugging and unplugging the data cable is eliminated, the mobile phone should still be close to the wireless charging plate when wireless charging, and can not be moved casually. So many people think that this is actually a "pseudo-wireless charging". However, users who have really experienced wireless charging should know that although it is not practical as imagined, it is by no means useless.
Low charging efficiency: Compared with wired charging, wireless charging is less efficient. That means it takes longer for users to fully charge. In addition, due to noneLine charging requires energy conversion between transmit and receive, so it may result in reduced battery life. Slow charging speed: Due to the low efficiency of wireless charging, the charging speed is relatively slow. This causes users to have to wait longer to complete the charge.
Today we will talk about the advantages and disadvantages of wireless charging treasure and wired charging treasure, as well as their applicable scenarios. Advantages and disadvantages of wireless charging treasure: Advantages: Easy to operate: Wireless charging treasure is really very convenient, because it uses electromagnetic induction wireless technology, you only need to put the device that supports wireless charging on it, it can be self-propelledMove to charge you, eliminating the tedious step of plugging.
Magnetic resonance wireless charging technology is a new type of charging method, which transmits energy through a magnetic field without the use of traditional wired charging equipment. Although this technique has certain advantages, it also has some disadvantages. The conversion efficiency of low-efficiency magnetic resonance wireless charging technology is generally only about 70%, which is low compared with wired charging.
Advantages and disadvantages of wireless charging: Advantages of wireless charging Reduce loss As we all know, when using wireless charging, just connect the wireless charging board to the power supply first, and then place the device that supports wireless charging inOn the wireless charging pad. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method.
Mobile phone wireless charging technology has developed very rapidly in recent years because it does not require a charging cable. However, with the use of the product, people also found a lot of shortcomings. So is wireless charging a magic charger or a publicity stunt? This is to analyze the advantages and disadvantages of wireless charging. Advantages To speak of advantages, there must be a reference.
1, protection interface: wired charging requires frequent insertion and removal of the charging cable, long-term use may lead to interface damage or wear. Wireless charging eliminates this problem, and the phone interface can remain in good condition for a longer time, extending the service life of the phone. Low charging efficiency: Compared with wired charging, wireless charging is less efficient. That means it takes longer for users to fully charge.
2, wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. Wireless charger is goodConvenient: Wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the phone interface, which can better protect the phone interface.
3, the advantages of wireless charging are: reduce loss, high adaptation rate, the disadvantages are: the distance is too small, only the transition technology; The benefits of wireless charging reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply first, and then place the device that supports wireless charging on the wireless charging board.
4, wirelessThe advantages of the charger: in theory, wireless charging technology is safe and harmless to the human body, the resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
5, although the technical content of the equipment is high, the economic cost of the equipment is higher, and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.
