CTOnews.com June 13 news, according to the charging head network reported that products that have passed the Qi 2 wireless charging protocol need built-in authentication chips, but authentication chips need to go through complex authentication links.

WPC Wireless charging Alliance launched the new Qi 2 wireless charging protocol in April this year. At present, most products on the market that support wireless charging support Qi wireless charging protocol, which is the previous generation standard of Qi 2 wireless charging protocol.

Compared to the current Qi standard, Qi2 uses magnetic power distribution technology, which claims to ensure a perfect match between the equipment and the charger, thereby improving energy efficiency. Qi2 will support the industry to develop faster wireless charging technology while ensuring that the charging process is always safe without shortening battery life or damaging the receiver.

In addition, Qi2 does not require plane-to-plane connection, but can support new product shapes such as AR / VR head display with magnetic locking function. It will also support new magnetic accessories for the back cover of mobile phones, such as external batteries, which means wireless charging panels from manufacturers such as Samsung and OPPO can use technology similar to Apple's MagSafe in the future.

In the following market products, more and more devices will begin to support Qi 2 wireless charging protocol, but no matter hardware manufacturers or 3C digital accessories manufacturers, if they want to make their products support Qi 2 wireless charging protocol, they can not bypass the authentication chip, and will not be able to bypass the authentication chip.

The authentication process of authentication chip is complex. After inquiry, CTOnews.com learned that manufacturers can complete most of the steps in the authentication process through "manufacturer CA service provider", which can speed up the authentication process.

At present, there are seven manufacturer CA service providers announced on the official website of WPC Wireless charging Alliance, among which Shanghai Fudan Micro Co., Ltd. is the only manufacturer CA service provider approved by WPC Wireless charging Alliance in China.

The faster the certification process, the sooner manufacturers can launch the corresponding products. CTOnews.com has previously reported that iPhone 15 series phones will be compatible with Qi 2 protocol. Users only need to buy wireless charging products that support Qi 2 protocol to provide full-speed wireless charging for their phones. There is no need to pay a high price for wireless charging products with "MFM" certification.
