The invention discloses a battery protection method which is suitable for a battery receiving charging voltage. The method comprises the steps that: whether a maximum charging electric quantity value is equal to a rated electric quantity value or not is judged, a first battery protection program is executed when the maximum charging electric quantity value is equal to the rated electric quantity value, and a second battery protection program is executed when the maximum charging electric quantity value is not equal to the rated electric quantity value, wherein the first battery protection program involves determining whether the charging voltage is greater than a bearable voltage of a battery and determining whether charging current is lower than a threshold current; and when the charging voltage is greater than the bearable voltage and the charging current is lower than the threshold current, the rated electric quantity value is taken as a display electric quantity value; and when the charging voltage is not greater than the bearable voltage or the charging current is not lower than the threshold current, the real-time electric quantity value of the battery is taken as the display electric quantity value; and the electric quantity of the battery is displayed on display equipment according to the display electric quantity value.
Description
technical field [0001] The present invention relates to a battery protection method, in particular to a battery protection method for adjusting the displayed power value of the battery. Background technique [0002] Existing hardware design and protection measures for batteries mostly use the embedded controller (Embedded Controller) to read the power, voltage, current and charging records stored in the battery fuel gauge (Gas Gauge), and then the embedded controller will The read data is transmitted to the operating system for analysis, and when the charging voltage received by the battery exceeds the threshold voltage it can carry, the overvoltage protection mechanism (Over Voltage Protection, OVP) will be activated for the battery to interrupt Charge the battery. [0003] Among them, in order to correctly report the information of the battery, the embedded controller usually does not make any modification to the read data after reading the data from the battery fuel gaug...
