And S203, if the battery is not charged and discharged for the first time, acquiring a historical residual capacity value stored when the last charging and discharging is finished.
The specific calculation method of the current residual capacity is as follows:
when the battery is in a discharging state, the current residual capacity is equal to the historical residual capacity value-discharging passing capacity;

Q2＝I2×T2。
in this step, when the discharging or charging is finished, the calculated current remaining capacity is stored as a historical remaining capacity value, so as to facilitate the subsequent calculation of the current remaining capacity.
And S3, calculating the current electric quantity value according to the current residual capacity and the overall capacity of the battery, and displaying the current electric quantity value.
In this step, the current electric quantity value is the ratio of the remaining capacity of the battery to the overall capacity of the battery.
Specifically, the entire battery capacity in the correspondence table is updated each time a charge-discharge cycle is completed, specifically, the battery is discharged when the battery is charged to a full charge voltage, the discharge passing capacity is calculated from the discharge time T1 and the discharge current I1, and the discharge passing capacity is substituted for the entire battery capacity in the correspondence table, so that the current electric quantity value can be calculated using the updated entire battery capacity as a reference, and the deviation between the calculated current electric quantity value and the actual electric quantity value can be minimized.
