first embodiment

Referring to FIG. 1, FIG. 1 is a schematic flowchart of a method for displaying the power level of a mobile terminal provided by an embodiment of the present invention. As shown in FIG. 1, the method includes the following steps:

Step 101: Obtain the target battery capacity value of the mobile terminal and the power value consumed by the mobile terminal, and determine the first power value according to the target battery capacity value and the power consumption value; determine the open circuit voltage of the mobile terminal, and search for a preset value according to the open circuit voltage. The battery aging parameter table is obtained from the battery aging parameter table, and the second power value corresponding to the open circuit voltage at the current temperature is obtained.

In this step, the above-mentioned target battery capacity value is calculated according to the theoretical battery capacity value and the battery capacity value detected by the fuel gauge device. The calculation process may be to take the smaller battery capacity value of the two or the average battery capacity value of the two The capacity value serves as the target battery capacity value here.

The theoretical battery capacity value may be determined by querying the battery aging parameter table preset when the battery leaves the factory. The battery aging parameter table is the parameter table obtained by the aging test of the mobile terminal battery before the mobile terminal leaves the factory. Parameter information such as the percentage of capacity), remaining power value, battery open circuit voltage (potential difference between the two poles of the battery when the battery is not discharged and open circuit), these parameter information form a corresponding parameter table; the battery capacity value detected by the fuel gauge device can be is the battery capacity value obtained according to the coulomb integral of the fuel gauge. The above-mentioned power consumption value of the mobile terminal is the total power consumption when the mobile terminal is used, which can be calculated by using the current Coulomb current integral, or can be detected by a power meter device such as a power meter chip of the mobile terminal.

The above-mentioned first power value is the percentage of the current remaining power value of the mobile terminal to the target battery capacity value, and the determination process may be to subtract the target battery capacity value from the power value consumed by the mobile terminal to obtain a difference value, and the difference value is: The current remaining power value of the mobile terminal, and then the ratio of the difference to the target battery capacity value is determined as the first power value. For example, if the target battery capacity value is 1000 mA, and the battery capacity value consumed by the mobile terminal is 100 mA, the first power value can be calculated to be 90%.

The above-mentioned open-circuit voltage is the potential difference between the two poles of the battery when the battery is not discharged and open-circuited. Alternatively, the load voltage of the mobile terminal is detected, and then the open circuit voltage is obtained through I (current intensity, currentintensity) R (resistor, Resistor) compensation, that is, the product of the load current and the preset internal resistance of the battery is taken as the consumption voltage, and the load voltage The sum of the consumption voltage is regarded as the open circuit voltage. In this embodiment, on the one hand, the open-circuit voltage can be determined by means of IR compensation, which makes up for the shortage of determining the open-circuit voltage when the mobile terminal does not have a fuel gauge device or the fuel gauge device detects incorrectly; The open-circuit voltage is calibrated, such as taking the average value of the above-mentioned open-circuit voltages to improve the accuracy of the determination of the open-circuit voltage.

Second, if the first power value is greater than the second power value, calculate the difference between the first power value and the second power value; calibrate the first power value according to the difference, and use the calibrated power value as the target power value. The calibration process is to determine the electric power calibration speed according to the difference value, and then gradually calibrate the first electric power value to the second electric power value. Among them, the larger the difference, the faster the corresponding power calibration speed. For example, if the first power value is 70%, the second power value is 50%, and the difference is 20%, the corresponding power calibration speed can be 1% per second. In this way, the calibration process can be completed after 20 seconds. Get a more accurate power value.

The battery aging parameter table is obtained from the battery aging parameter table, and the second power value corresponding to the open circuit voltage at the current temperature is obtained.

In this step, the above-mentioned target battery capacity value is calculated according to the theoretical battery capacity value and the battery capacity value detected by the fuel gauge device. The calculation process may be to take the smaller battery capacity value of the two or the average battery capacity value of the two The capacity value serves as the target battery capacity value here.

The theoretical battery capacity value may be determined by querying the battery aging parameter table preset when the battery leaves the factory. The battery aging parameter table is the parameter table obtained by the aging test of the mobile terminal battery before the mobile terminal leaves the factory. Parameter information such as the percentage of capacity), remaining power value, battery open circuit voltage (potential difference between the two poles of the battery when the battery is not discharged and open circuit), these parameter information form a corresponding parameter table; the battery capacity value detected by the fuel gauge device can be is the battery capacity value obtained according to the coulomb integral of the fuel gauge. The above-mentioned power consumption value of the mobile terminal is the total power consumption when the mobile terminal is used, which can be calculated by using the current Coulomb current integral, or can be detected by a power meter device such as a power meter chip of the mobile terminal.

For example, if the target battery capacity value is 1000 mA, and the battery capacity value consumed by the mobile terminal is 100 mA, the first power value can be calculated to be 90%.

In this embodiment, the target battery capacity value is determined by the theoretical battery capacity value and the battery capacity value detected by the fuel gauge device, a calibration process of the theoretical battery capacity value is added, and the target battery capacity is improved when the fuel gauge device is damaged or detected incorrectly. accuracy of the value.

Alternatively, the load voltage of the mobile terminal is detected, and then the open circuit voltage is obtained through I (current intensity, currentintensity) R (resistor, Resistor) compensation, that is, the product of the load current and the preset internal resistance of the battery is taken as the consumption voltage, and the load voltage The sum of the consumption voltage is regarded as the open circuit voltage. In this embodiment, on the one hand, the open-circuit voltage can be determined by means of IR compensation, which makes up for the shortage of determining the open-circuit voltage when the mobile terminal does not have a fuel gauge device or the fuel gauge device detects incorrectly; The open-circuit voltage is calibrated, such as taking the average value of the above-mentioned open-circuit voltages to improve the accuracy of the determination of the open-circuit voltage.

The calibration process may be to perform calibration according to the power calibration speed determined by the difference. Description in the Examples. In this way, when the displayed power value of the mobile terminal is greater than the theoretical power value (the second power value), the power value is smoothed to improve the accuracy of power display.

For example, the larger the difference, the faster the corresponding power calibration speed. For example, if the first power value is 70%, the second power value is 50%, and the difference is 20%, the corresponding power calibration speed can be 1% per second. In this way, the calibration process can be completed after 20 seconds. Get a more accurate power value. It can also be a negative correlation corresponding relationship, that is, the larger the difference, the smaller the corresponding power calibration speed, which can be set according to the actual situation.
