Problems solved by technology

[0002] Current smart devices usually use a variety of external devices due to their diverse requirements for external functions. Since the voltage and power consumption of different external devices are very different, the original single boost to the main chip or current metering chip The working voltage cannot be fixed, some equipment needs high voltage, and some equipment needs low voltage, the maximum current and normal working current allowed by the main chip or the current metering chip cannot meet the requirements.
[0003] By obtaining the voltage and current of the onboard peripherals, the internal galvanometer calculates the power consumed per unit time, and then obtains the power consumed by the entire working process through quantitative statistics, thereby calculating the current battery power. However, in many When it is installed externally and supports some high-current and high-voltage working equipment, the original single power metering chip cannot meet the demand, and the high-voltage power metering chip not only needs to rewrite the driver code, but the cost is high

Abstract

The invention provides a curve acquisition metering method and an apparatus thereof. The method comprises the following steps of collecting a plurality of voltage values of a battery, and acquiring charge and discharge data according to a relation curve corresponding to the voltage values; calculating the plurality of voltage values through using an average algorithm to obtain a stable voltage value; analyzing discreteness of the stable voltage value within preset time so as to obtain a changed voltage value; determining whether a fluctuation the changed voltage value is reasonable; if the fluctuation is reasonable, storing the stable voltage value; and analyze a state of a charging IC, and acquiring an electric quantity value of a current battery according to the stable voltage value and the charge and discharge data. An electric quantity metering chip does not need to be used. Through acquiring the voltage values of the battery, the electric quantity value of the current battery can be calculated so that a workload of a hardware design is greatly reduced and cost is saved.

Description

technical field [0001] The invention relates to the technical field of Android systems, in particular to a method and device for curve collection and measurement. Background technique [0002] Current smart devices usually use a variety of external devices due to their diverse requirements for external functions. Since the voltage and power consumption of different external devices are quite different, the original single booster chip or current metering chip The working voltage cannot be fixed, some equipment needs high voltage, and some equipment needs low voltage, and the maximum current and normal working current allowed by the main chip or current metering chip cannot be satisfied. [0003] By obtaining the voltage and current of the onboard peripherals, the internal galvanometer calculates the power consumed per unit time, and then obtains the power consumed by the entire working process through quantitative statistics, thereby calculating the current battery power.
