Among them, 2855438+0 is a brand-new self-developed chip of Xiaomi. The official statement is that BMS (Battery Management System), one of the core technologies of electric vehicles, is used for reference. It can monitor millisecond battery safety in real time, realize the most accurate battery life prediction in the industry, and effectively improve battery life.
Xiaomi officially released a long picture, detailing the use of the G 1 chip, which is divided into three functions: battery health, accurate prediction and battery life improvement.
Battery health means that 2855438+0 can monitor the slight change (ISP) of the internal materials of the mobile phone battery caused by falling and collision, and can also dynamically analyze the reasonable temperature range (SOA) of the battery under charging, heavy load and other scenarios according to the temperature rise model, so as to provide the battery maintenance function according to the battery health degree and prolong the battery life.
Accurate prediction can predict the available time in minutes according to the user's usage status and habits, and the accuracy is much higher than the estimation function that comes with Android.
In terms of battery life improvement, 2855438+0 can accurately adapt to the discharge curve characteristics of silicon-oxygen anode and dynamically adjust the discharge state (DTPT), and the overall battery life is improved by 3-5%.
Under the joint action of silicon-oxygen negative battery, surging P 1 and surging G 1, "Xiaomi surging battery management system" can make Xiaomi 12SUltra have fast wired surging second charging and wireless second charging, and at the same time become the digital flagship mobile phone with the longest battery life in Xiaomi's history.
