S201: When the terminal device is powered on for the first time, the RTC (Real-time Clock) and the software fuel gauge are started.

Terminal devices generally have an RTC function, and the RTC function can provide a reliable time for the operating system. This time can be read by other software, and the time of reading is called hardware system time.

When the terminal device is powered on, the running program calculates the battery power. This program is called a software fuel gauge. The software fuel gauge operation requires a battery charge value as the initial condition. This battery charge value is called the initial battery charge.

S202. Calculate initial battery power and initial power time.

After the terminal starts the software fuel gauge, the software fuel gauge calculates the current battery power according to the current battery voltage, current and temperature status. This battery power is called the initial battery power. The lookup table here refers to the experimental data obtained during the charging and discharging process of the battery by collecting the voltage, current and temperature status and time of the battery before leaving the factory.

S210, calculate and record a new initial battery power P0.

The new initial battery charge P0 can be calculated by the long shutdown time and the file battery level. The calculation method is that the shutdown leakage current Pt1 of the terminal device is obtained by multiplying the shutdown duration by the shutdown leakage current S1 of the terminal device, and the battery self-discharge power Pt2 is calculated by multiplying the shutdown duration by the self-discharge rate S2 of the battery of the terminal device. The new initial charge P0 can be obtained by subtracting the shutdown leakage power Pt1 and the battery self-discharge power Pt2 from the file battery power P2. The shutdown leakage current S1 of the terminal device and the self-discharge rate S2 of the battery are data obtained by the charge and discharge experiments of the battery.
