Embodiment Construction

[0021] refer to figure 1 , figure 1 It is a schematic flow chart of an embodiment of the battery capacity detection method of the present invention, the method comprising:

[0022] S11: Obtain the accumulative sum of the capacity of the standard battery.

[0023] Wherein, the accumulated capacity of the standard battery is obtained according to the accumulated capacity of each cycle of use of the standard battery.

[0024] Such as figure 2 as shown, figure 2 It is a schematic diagram of the power change of the battery during the use cycle, where the left side of the horizontal axis represents the number of use cycles of the battery, and the vertical axis represents the power of the battery. from figure 2 It can be seen from the figure that with the continuous increase of the battery life cycle, the power of the battery continues to decrease. Among them, when the power of the battery decreases to a certain value (N), the performance of the battery is extremely poor and ...

Abstract

The invention discloses a battery capacity detection method and device. The detection method comprises steps as follows: a capacity accumulated sum of a standard battery is acquired; the capacity accumulated sum of the standard battery is obtained by accumulating capacity of the standard battery during each use cycle; the discharge capacity of the current battery is detected, each discharge capacity during the current use cycle is accumulated, and the accumulated sum of the discharge capacity is obtained; the accumulated sum of the discharge capacity is compared with the capacity accumulated sum of the standard battery to determine the capacity of the current battery. By means of the scheme, the battery capacity after cyclic use can be simply and accurately determined.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a method and device for detecting battery capacity. Background technique [0002] Most of the existing mobile terminals work with a built-in battery and external charging. During the charging and discharging process of the battery, the mobile terminal needs to display the battery power in real time. For example, the battery power displayed on the status bar of a commonly used mobile phone is average. is displayed as a percentage. [0003] At present, in the algorithm processing of fuel gauges in the industry, there are mainly the following steps: 1. Modeling at different temperatures and different discharge currents; 2. Proposing the initial capacity of the battery; 3. The charging and discharging power algorithm; 4. In the cycle In the process of updating the capacity of the battery. In the algorithm of the fuel gauge, a very important parameter is the capacity Q MAX As we a...
