At the same time as the release of Xiaomi 12 Pro, Xiaomi also launched the third self-developed chip "Surging P1", a special fast charging chip, and the corresponding "Immortal Second Charging" technology also won the second prize of the 2021 Xiaomi Annual Technology Award.
Xiaomi today also officially disclosed the story behind this technology.
Xiaomi said that after the release of Xiaomi second charging technology, the charging technology team has been thinking about the next generation of fast charging solutions, and the immortal second charging is the result of Xiaomi's exploration and thinking, on the one hand, pursuing a more extreme fast charging experience, on the other hand, pursuing the best balance between endurance and speed.
With the blessing of this technology, 120W single cell second charge can be fully charged in 18 minutes with 4600mAh, and even 200W wired charging technology can be fully charged in 4000mAh in 8 minutes!
The 120W single-cell charging concept is the first of its kind in the industry. Xiaomi debuted the 120W 5C graphene-based battery cell system, equipped with a new self-developed forward 4:1 surging P1 chip, the first SIC charging algorithm, forward 1:1 mode bright screen charging efficiency is higher, forward 2:1 mode compatible with multiple chargers, reverse 1:2/1:4 mode up to support 30W reverse charging.
The 200W wired charging technology adopts the 10C graphene-based battery with the strongest charging capacity in the industry, which not only ensures good heat dissipation, but also takes into account the thinness and lightness of the fuselage.
In terms of security, Xiaomi has also been included in a more complete protection strategy. Compared with the previous generation of second charge technology support 34 security protection, The Immortal Second Charge was upgraded to 42 security protection and obtained the 3.0 certification of the T V Security Fast Charge System of Rheinland.
Wang Feng, vice chairman of the Technical Committee of Xiaomi Group, commented on the Immortal Seconds Rush technology:
"The larger the battery capacity, the harder it is to do fast charging. Xiaomi engineers continue to innovate, in the charging performance, the endurance of the whole machine, the fuselage thickness of the three dimensions to achieve the best balance, breaking the industry charging speed record, for the first time wired charging into the 10-minute era. The speed record itself is used to be broken, and this breakthrough is not the end for Xiaomi, but a new starting point. ”
Xiaomi also revealed that the next generation of fast charging technology will of course be faster, but not only fast, but also to achieve the best balance between temperature and endurance, to give users a better charging experience.
