Embodiment 1

[0131] Please refer to figure 1 , a method for measuring battery power, comprising the steps of:

[0132] S1. Determine the state of the battery, judge whether battery voltage sampling can be performed according to the state, if yes, execute step S2, otherwise, return to step S1;

[0133] Wherein, judging whether battery voltage sampling can be performed according to the state specifically includes:

[0134] S11. Preset the status of the battery, the status includes a normal status, a ready-to-collect status, a charge stabilization delay status, and a voltage ripple delay status;

[0135] S12. Judging whether the battery is in a ready-to-collect state, if so, battery voltage sampling can be performed; otherwise, turn on the setting of reducing the sampling voltage ripple, and set the state of the battery to a voltage ripple delay state;

[0136] S13. Determine whether there is an external power connection, if so, turn off battery charging, and set the state of the battery to...

Embodiment 2

[0172] The difference between the embodiment and the first embodiment is that the step S22 also includes:

[0173] Setting an alarm flag, if the sampling is unsuccessful, setting the alarm flag and performing an alarm prompt;

[0174] After determining the power consumed in the unit sampling time t according to the correction value, and calculating the current battery power, it is judged whether the alarm flag is set. If so, the correction value needs to be adjusted according to the current battery power, specifically:

[0175] Judging the charging status of the battery, if there is an external power connected, it is in a fully charged state, then judge whether the current battery power is greater than or equal to the total power of the standard battery, if so, adjust the correction value to 0; if there is an external power connected, it is in a fully charged state Status, to judge whether the current battery power is less than or equal to the total power of the standard batte...

Embodiment 3

[0178] The difference between the described embodiment and the first embodiment is that step S1 is executed at preset time intervals, wherein, for the determination of the sampling time period t, if there is an external power access, the sampling period t is 10s; if there is no external power access, Then the sampling period t is 2s.

Abstract

The invention provides a method and terminal for measuring the electric quantity of a battery. The method comprises the steps of judging whether voltage sampling can be performed on the battery or notaccording to the state of the battery; determining a correction value according to the real-time battery electric quantity and the historical battery electric quantity in the calculation of the electric quantity; determining the electric quantity consumed within the sampling time according to the correction value; and determining the current battery electric quantity according to the consumed electric quantity and the historical battery electric quantity. According to the invention, the stability of battery voltage obtained in the sampling is ensured, and thus the stability and accuracy of the electric quantity converted according to the real-time voltage are ensured, so that the current electric quantity state of electric equipment can be accurately obtained by a user.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a method for measuring battery power and a terminal. Background technique [0002] Battery power is an important indicator of an electronic device. Through the battery power, a user can obtain the current power state of the electronic device and determine whether charging is required. Therefore, the measurement of battery power has always been a research hotspot in the industry. [0003] At present, there are several methods for measuring battery power: open circuit voltage measurement method, power accumulation method, internal resistance measurement method, mathematical model establishment measurement method, and measurement method based on fuzzy reasoning and neural network. However, in the above measurement methods, either the scope of application is limited, or the measurement error is large, or the complexity is large, therefore, the battery power cannot be measured well. Conten...
