Problems solved by technology

[0009] In addition, the total power of the existing battery will not increase after the battery is fully charged until it is fully discharged, but the latest Impedance Technology Battery can also increase the total power of the battery in addition to the battery remaining. It is impossible to accurately express the percentage of battery remaining

Embodiment Construction

[0023] The method for calculating the remaining battery level of the above-mentioned portable terminal will be described in detail below with reference to the accompanying drawings.

[0024] figure 1 It is a schematic diagram of the structure of the display system of the present invention.

[0025] refer to figure 1 , the whole system composition of the present invention comprises the following parts: the battery 100 that provides driving power to the portable terminal; the EC102 that reads the total electric quantity of the inserted battery and the remaining quantity; A battery management module 104 that calculates the remaining capacity; and a display unit 106 that displays the percentage of remaining battery capacity calculated by the battery management module 104;

[0026] The above-mentioned battery 100 is chargeable and dischargeable, and is a battery used in a portable terminal.

[0027] The EC 102 reads the total power and remaining power of the battery 100 at any t...

Abstract

The invention relates to a battery margin computational method of a portable terminal. The battery margin computational method of the portable terminal comprises the stages of: computing and displaying the total quantity of electricity of the battery when the battery is inserted; judging whether the battery margin variable quantity exceeds the prescribed value; computing the modified margin and informing the computed margin to a battery management modular; computing and displaying the ratio between the modified margin and the total quantity of electricity of the battery when the battery is inserted. By adopting the method, the information of the battery margin can be supplied more accurately, thus being very useful.

Description

technical field [0001] The present invention relates to a battery of a portable terminal, in particular to a method for calculating the remaining battery capacity. Background technique [0002] When using a mobile terminal, it is very important for the user to check the battery information. Because if the user confirms the usage status of the battery at any time and knows how much the battery is used, he can prepare in advance. [0003] In a portable terminal equipped with a battery, the expression method for providing the user with battery remaining information can be as follows: [0004] Battery (battery) (%) = Remaining Capacity (battery remaining capacity) / Full Capacity (battery total capacity) × 100 [0005] That is to say, the percentage (%) of the remaining battery capacity is represented by the ratio of the remaining capacity of the battery (Remaining Capacity) to the total capacity of the battery (Full Capacity). [0006] In order to calculate the above-mention...
