Wireless charging private protocol is rampant and Qi fragmentation is not optimistic

The wireless charging standard makes Qi fragmented. Although it also supports the Qi standard specification, there are many private protocol wireless charging standards in the market, such as Apple 7.5W, Xiaomi 7.5W, Huawei 10W, SONY 9W, and Samsung 10W. The self-reliance standards, incompatible with each other, and the increase in the cost of consumer accessories purchases, led to the fragmentation of Qi is not optimistic.


WPC is the first industry standard organization for wireless power and is the maker of "Qi" specifications. There are a large number of members worldwide, so far more than 500: including Apple, Samsung, Google, Huawei, Xiaomi, Haier and other domestic and international famous enterprises. Ms. Shuang was the Marketing Director of the IEEE Standards Association. The WPC sets a normative industry standard for 15W low-power applications. The purpose of this standard is to achieve interoperability between various charging boards and portable devices. Products that have been certified by the WPC Consortium will be identified with the words "Qi" and the terminals with "Qi" may be charged on all charging boards marked with the logo. The annual fee for joining WPC ranges from US$5,000 to US$25,000. Only joining the WPC Wireless Charging Alliance can earn Qi certification.

Qi wireless charging specification significance


Qi is a mature open standards specification designed to help consumers use the most advanced technologies. Qi certified products need to pass compatibility and safety tests. Qi's Logo is a symbol of compatibility and safety. Different brands of products, as long as there is a Qi logo, Qi wireless charger can be used to charge. The series test verifies that the charger is compatible with other Qi phones, and at the same time, it can ensure that the product is safe and reliable, and can prevent injuries and prevent equipment damage (heating of coins, damage to mobile phones, damage to NFC cards) and so on.

According to Keliway statistics, as of April 30, 2018, the number of WPC members has increased to 534. Last September, Apple’s new iPhone was confirmed to carry wireless charging. At that time, there were only 251 WPC members. The number of members now doubled directly, which directly reflected the fiery level of the wireless charging market.

Wireless charging is undoubtedly a hot topic in this year's technology industry. After the Apple iPhone 8/X adopts the wireless charging function, several big players in the Android camp have started to follow suit, and some even have wireless fast charging technology. In fact, many mobile phones have been equipped with wireless charging technology since the commercial use. Charging head network learned from WPC's official website that the number of the latest Qi-certified mobile phones of the WPC Wireless Charging Alliance is as many as 60 models.

It can be seen that the latest Qi-approved mobile phones announced by the WPC Wireless Charging Alliance have already reached a considerable scale. With the re-emergence of the wireless charging function, there will be more and more terminal devices supporting wireless charging, and the wireless charging infrastructure in public places will gradually form a scale. A future without charging constraints will soon come.
