Title:
COMPENSATION METHOD AND APPARATUS FOR BATTERY VOLTAGE, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/087373
Kind Code:
A1
Abstract:
The present application provides a compensation method and apparatus for battery voltage, and a terminal device. Battery power can be calculated accurately by calculating smooth voltage, without collecting the charge and discharge current of a battery. In scenarios in which battery power is false high or false low, the battery power can be accurately calculated on the basis of the obtained smooth voltage, so that the power displayed is more accurate. The method is applicable to a terminal device comprising a battery. The method comprises: a terminal device obtains acquired voltage, VT acquisition, of a battery at the Tth time point; the terminal device determines actual compensation voltage at the Tth time point according to the smoothed voltage, VT-1 smoothing, at the T-1th time point and the acquired voltage, VT acquisition; the terminal device uses the actual compensation voltage at Tth time point to compensate for the acquired voltage, VT acquisition, at the Tth time point to obtain a compensated voltage value; the terminal device performs smoothing processing using the compensated voltage value and the smoothed voltage values at the first N time points of the Tth time point to obtain the smoothed voltage, VT smoothing, at the Tth time point.
