Embodiment Construction

[0044] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] The main solution of the embodiment of the present invention is: for a mobile terminal including a coulomb counter, detect the current temperature of the mobile terminal, and determine the calibration coefficient of the coulomb counter according to the current temperature of the mobile terminal, and then obtain the current coulomb value and history detected by the coulomb counter Detect the coulomb value and obtain the historical calibrated coulomb value, and finally calibrate the current coulomb value according to the coulomb meter calibration coefficient, the historical detected coulomb value and the historical calibrated coulomb value to obtain the current calibrated coulomb value.

[0046] Due to the inertia problem caused by the rapid change of the battery voltage with the current, the battery power display...

Abstract

The invention discloses a coulometer calibration method, a mobile terminal and a computer storage medium. For the mobile terminal comprising a coulometer, present temperature of the mobile terminal isdetected, a coulometer calibration coefficient is determined according to the present temperature of the mobile terminal, secondly, a present coulomb value and historical detection coulomb values detected by the coulometer are acquired, historical calibration coulomb values are further acquired, and lastly, the present coulomb value is calibrated according to the coulometer calibration coefficient, the historical detection coulomb values and the historical calibration coulomb values to acquire a present calibration coulomb value. The method is advantaged in that through calibrating the present coulomb value detected by the coulometer according to the coulometer calibration coefficient, the historical detection coulomb values and the historical calibration coulomb values, accuracy of the coulomb value is substantially improved, and accuracy of the cell capacity acquired through measurement is substantially improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a coulomb counter calibration method, a mobile terminal and a computer storage medium. Background technique [0002] With the advent of lithium batteries, lithium batteries have been widely used in mobile terminals such as smart phones, tablet computers or multimedia players due to their advantages such as high storage energy, long life, light weight and no memory effect. In order to accurately calculate and display the battery capacity, an integrated circuit (Integrated Circuit, IC) chip is embedded in the mobile terminal, and the IC chip supports the monitoring function of the battery voltage and battery temperature, and also supports the calculation of the coulomb counter. In such a hardware environment, the calculation of battery capacity generally adopts the voltage method or the coulomb counting method. Charge to estimate battery capacity. [0003] When using the...
