At present, there are many wireless charging on the market, but the maturity and the degree of penetration is the qi standard electromagnetic induction wireless charging product program, such as TI, Freescale, etc., Lingyang, China (Based on Lingyang, TI's wireless charging product disassembly), even some single-chip plan, the market situation is optimistic, there seems to be a scales of a heavyweight, and Apple's Apple Watch is undoubtedly the "candidate". Just n't I mention a wireless charging transmitting end evaluation board scheme based on electromagnetic induction principle - WCT-5W1CITX from Freescale Semiconductor.
Disclosure of articles. 1882.>> Flexible configuration, ultra-low power Freescale wireless charging launcher WCT-5W1Coiltx evaluation
@High brother talks about wireless charging or saying that radio can pass, the concept is very early, but it is really fired in these two years. Wireless charging products have been used for half, because it is not mine, it is borrowed. It's a friend of a friend, forgot the specific model, but it is wireless charging, it seems to be the selling point of the mobile phone. Personal feeling can also be, very convenient, lazy people don't need to do USB, mainly from what is easier to pick up, no need to pull what is. >>> Click Details
@Treasuredog Flyis Carl is actually doing well, can have such a high efficiency, but to tell the truth, the smart device's wireless charging I am not optimistic, purely a thing of the pants put P, you can charge wirelessly Is it poor in your own bag with a small harness? What do you think? Wireless charging personal feelings have a prospective industry in electric vehicles, but the form is the industry of electric vehicles, and consider making wireless charging parking lots, but this cost is imagined! >>> Click Details
@Shaoziyang has long paid attention to the technology of wireless charging, and it has also tested wireless charging things, including wireless charging chips and Ti BQ500210EVM developing boards less than 10 yuan. From the shape, Freescale's wireless charging launcher WCT-5W1Coiltx and Ti's BQ500210EVM are somewhat similar. >>> Click Details
@FJFHJMH The basic functions of their basic functions are also supported QI standards, and wireless charging management can be easily and convenient. It feels more of Freesclae's chip function, more complicated; Ti is more concise in power management, which may be greatly enhanced after the NS is acquired with Ti. >>> Click Details
@Janson__Huang looked at the introduction, the wireless charging seems to be very fun, but I looked at the comparative map with the development board. I feel that this board looks quite big, can you make a watch so small, a magnetic ring power adapter The design is also quite ideas, but I don't know if the user forgets that the power adapter without a magnetic ring will affect the charging efficiency when the user forgets the power adapter. >>> Click Details
@FuyuanW efficiency is a major factor that hinders its development, QI standard wireless charging efficiency is generally low, generally 50 ~ 70%, distance and location also have a lot. Another disadvantage that it brings is a fever problem. For example, the BQ51013B of Ti, the DEMO plate test temperature is 25 degrees Celsius at room temperature, and when the output current is 700mA, it is easy to more than seven or eighty degrees, and the use of mobile terminals will often limit charging current. Smaller to balance the effect of temperature on the whole machine experience. >>> Click Details

@ Gaon2 Wireless Charging Program has been launched for several years, many manufacturers are also constantly improving the performance of the product. It is said that the current efficiency can have reached 70%. In some special requirements, it has been widely used if there is no environment in which a wired charging is not possible. But individuals believe that unlimited power efficiency may exceed wired ways. Small volume mobility does not want to have a complex circuit design. Therefore, in the current situation, the civil market has to be discovered.
@ 收 These wireless charging technologies look good, but the products made are higher, and the volume is large, which greatly limits its use. Moreover, the current device manufacturer's response to wireless charging is not active, most equipment (including mobile phones, tablets, etc.) does not support this feature. Although a small number of mobile phones have wireless charging interfaces, they can DIY, but the cost is not low, and it seems that the effect is not ideal. I hope that Freescale will continue to improve these aspects, so that everyone can use wireless charging technology.
@ HuixianFXT has not yet used a wireless charging product, which feels that it should be priced and compatible to limit its promotion. In addition, there is still a lot of standards of wireless charging, and there is no unified standard! This will definitely bring certain difficulties to different mobile phone manufacturers. . . . If you use it, you can only try it, should you use it or very convenient! >>> Click Details
@Shepherd does not have a wireless charging device, but the previous colleague's Lumia 920 is equipped with a wireless charger, and the wireless charging that is considered to be recharged will be charged casually. When we are charging, we all say that this is too pit, because the charger is transmitted by electromagnetic induction principle, and there will be thermal energy on the charging board. We also say that this is "hand warmer." At that time, there was always a relatively slowed wireless, and we specially compared it once. I feel that the time of charging is not too much, so I think that charging efficiency is almost. Not very convenient, because the wireless charging of the mobile phone is not convenient, because the charging is not moving. >>> Click Details
@Xueyulangren should say that Freescale's appearance is still very nice, with netizens take TI and its comparison, TI's wireless charging solution I also have been evaluated. For this evaluation board, a change in Freescale should be said to be very generous, providing a lot of accessories, and beautiful packaging. For electronic enthusiasts, it can be used as a "collection". >>> Click Details
