This article to talk about why no one to improve the wireless charging speed, and wireless charging power does not increase the corresponding knowledge, I hope to help you, do not forget to collect the site oh. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Why is wireless charging so slow
2, the loss of components affects the internal resistance of wireless charging fast and slow components, and the conversion efficiency of the system is high. The selection of components such as triode with small internal resistance can greatly improve the efficiency of wireless charging. However, with low internal resistance, the cost will be relatively high.
3, increase the output, you can select from the equipment, select a good electromagnetic coil. Because the transmitter and receiver of wireless charging are covered with wireless charging coils, the coils will have losses when working, and the use of good materials can reduce the coil loss, which can greatly improve the efficiency of wireless charging. In terms of loss reduction, you can optimize the selection of lines and componentsChoose to deal with. Streamline and optimize the line, and select good materials for components to reduce output losses.
4, What you want to ask is the reason why the wireless charging speed of the phone 5 is slow? The following: Low charger power: Using a low power charger, the charging speed will be slow. It is recommended to use a high quality, high power charger to improve the charging speed. The charging cable is faulty: The charging cable is disconnected or damaged, which may slow down the charging speed. You are advised to check the charging cable to ensure that it is properly connected.
5, wireless charger charging speed is slow, there are the following possibilities: 1, noneThe device wireless charging power itself is not large. 2, the wireless charging receiver of the mobile phone, the charging current supported is not large. It is recommended to change a high-power wireless charging board, such as a certain meter, which has more than ten coils, although it is not opened at the same time, the effect will be good.
Wireless charging, is originally much slower than wired charging. Wireless charging sells convenience, not charging speed. Moreover, the charging speed is directly related to the power consumption of the phone. The fastest way to charge is in flight or offline mode. If you are connected to WiFi, playing games, and then using wireless charging, obviously the charging speed will be much slower.
The voltage of the wireless charger will not be too stable, and the voltage to be generated will be smaller with the transmission distance, the current will be small, and the charging will be slow. But it's safer than some wires.
The disadvantage of WiFi wireless charging technology is that it is slow to charge, and this WiFi wireless charging has not been widely popularized, and to use WiFi wireless charging, the premise is that the mobile phone must support it, and WiFi must also be upgraded.
Wireless charging for mobile phones, computers, cameras and other electronic products, is only a new function on the cake, but for electric vehiclesIndustry, however, may be the key to jump-starting the entire market. However, at the current level of technological development, the efficiency of wireless charging is lower than that of wired charging. If wireless charging is used, there is no exposed connector for wireless charging of electric vehicles, so as to completely avoid safety hazards such as leakage and electricity running.
Disadvantage 2: Charging speed is not faster than line charging In charging speed, wireless charging compared with wired charging there is still a certain gap. Experiments have proved that, taking iPhone X as an example, wireless chargers with the same power and current will be used in the same environmentA full charge with only 1% of battery left took nearly half an hour longer than a wired charger. It greatly reduces the work efficiency.
The phone is fully charged, there is a sense of security. When you sleep, you toss and turn to find the charging cable, you need to turn on the light when it's dark, jack. Now the convenience of wireless charging is in place in one step. And once the charging line is more, this one and that one, it looks very annoying for users. Wireless charging does not plug in the trouble, in life, so that the mobile phone has an unprecedented pleasant experience, especially now, the speed of wireless fast charging is significantly improved.
Support wireless charging for the large factoryFlagship, the price is too expensive, which should be a very important factor. Looking at all the models that support wireless charging on the market at present, most of them belong to the flagship positioning and are expensive, such as Samsung Galaxy series, Apple iPhone X, iPhone8 series, the price of these products is often five or six thousand yuan, or even higher, which is destined to have a relatively small audience.
1, wireless charging efficiency is lower than wired charging,However, in the future, with the rapid progress of wireless charging technology, it is likely that the charging efficiency will be better than that of wired charging. However, at present, the technology of wireless charging is not advanced enough, so the charging efficiency of wireless charging technology is lower than that of wired charging. At this stage, wireless charging is more as a supplement and auxiliary to wired charging.
2, different. Moreover, according to different wireless charger manufacturers now, the current and frequency are not the same. (The students themselves bought one online, it is said that the speed is relatively fast. The production method is to buy a wireless charger to receive the metal pole of the deviceAttach it to the charging electrode sheet of your own phone, then drag the wire outside and pick it up from the outside.) The heat is caused by the large current in the charger, which leads to obvious heat.
3, wireless fast charging is not very fast, nor very slow. Wireless fast charge is much faster than wireless fast charge, and slower than wired fast charge. The power that the charging head wired outputs to the wireless fast charge base is not the wireless fast charge output power but the wireless fast charge input power. Charging time of more than 2 hours of wireless fast charge, not as fast as the wired fast charge of 1 hour and 30 minutes, is not fast charge. It takes two and a half to charge 18WHourly wireless fast charge efficiency 60%.
4, you need to unplug the data cable, connection charging needs to plug in the data cable again, this time the wireless charger only needs to place the phone on the sensor can be charged. Charging efficiency: In the case of the same charging time, the power of the commonly used wired battery charger after charging is 93%, and the power of the wireless charger after charging is 88%. Obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology.
