Abstract

The invention provides a method for realizing monotone change of battery power. The method comprises the following steps: (1) sampling the battery to obtain the sampling value of the current voltage; (2) calculating the current effective value according to the obtained sampling value of the current voltage; (3) detecting the bottommost sampling value of the battery voltage, and judging whether the bottommost sampling value of the current voltage is greater than the effective value obtained in step (2); and (4) if the detected bottommost sampling value of the current voltage is greater than the effective value, using the effective value as the sampling value of the current voltage, and if the detected bottommost sampling value of the current voltage is less than or equal to the effective value, directly using the bottommost sampling value of the current voltage as the sampling value of the current voltage. When detecting the voltage, the invention continuously updates the sampling value of the regulation voltage to ensure that the sampling value of the current voltage is the lowest, thereby solving the problem of electric quantity display error caused by the virtual electricity of the battery; and thus, the battery power display monotonely changes in a gradual decrease way and accurately reflects the current battery state.

Description

technical field

[0001] The invention relates to portable electronic products, in particular to a method for monotonously changing battery power of the electronic product. Background technique

[0002] Now more and more users are using portable electronic consumer products, and the types and functions of electronic products are also developing rapidly, such as mobile phones, digital cameras, electronic dictionary machines, etc. However, almost all users of electronic consumer products will encounter such problems. During use, there will often be changes in the battery power, and the display of the remaining battery power will often change from "one bar" to "two bars". "Gate battery", commonly known as virtual power or floating power, makes it impossible for users to know the exact battery power and whether it should be charged, causing troubles to users. see figure 1 , when the battery has empty power, the sampling value of the voltage is different each time, resulting in t...
