A method for realizing battery power display of current discharge

Abstract

The invention discloses a heavy current electric quantity display realization method. The heavy current electric quantity display realization method comprises steps of S1: respectively testing working time of a standard battery under various system states when the standard battery is in 100% electric quantity, S2: equally dividing the standard battery into 100 parts when the standard battery is in the 100% electric quantity, respectively calculating the working time of the standard battery which is spent on consuming one equally-divided value of the electric quantity under various system states and storing, S3, detecting practical residual electric quantity of a practical working battery, obtaining a total equally-divided value of the practical residual electric quantity and displaying in a non-system state, S4, detecting practical working time of the practical working battery under various system states, respectively calculating practical equally-divided values which are consumed, calculating the residual electric quantity equally-divided value after practical working and displaying and S5, repeating a step S4 until a residual equally-divided value is 0. Through the heavy current electric quantity display realization method, electric quantity detection is even, electric quantity detection is stable and display is direct.

Description

technical field [0001] The invention relates to the field of computer software applications, in particular to a method for realizing battery power display of current discharge. Background technique [0002] In the prior art, all kinds of portable electronic products on the market are basically powered by batteries, and the corresponding power display is measured by the voltage detection method of the ADC circuit of the MCU to measure the battery capacity, which is usually displayed in the form of power grids or percentages. However, this power display has the following disadvantages: [0003] 1. The accuracy (resolution) of the power is not high; [0004] 2. The power display will change repeatedly, for example, after a heavy load is lowered from two bars to one bar, the load is lighter after a while, and then bounces back to two bars; [0005] 3. The sampling method of the ADC battery voltage is generally only suitable for the voltage when the current consumption is low. ...
