【Technical field】

The present invention relates to the field of terminal technology, in particular to a battery performance detection method and a battery performance detection device.

【Background technique】

At present, batteries are essential accessories of existing electronic mobile devices, especially lithium batteries, which are widely used. Generally speaking, the deep charge and discharge cycle of a lithium battery is about 500 times. The deep discharge cycle refers to the process of using up the battery power and then recharging it. The aging speed of the lithium battery is determined by the temperature and the state of charge. In actual use, try to Avoid using in an environment where the temperature is too high, and avoid deep charging and discharging of lithium batteries. The main reason for the decrease in battery capacity is the increase in the internal resistance of the battery due to oxidation.

Because existing electronic mobile devices are often used to watch movies and play games, they discharge quickly, and sometimes need to be charged twice a day, and their high-temperature use often leads to battery aging and serious capacity drop. Therefore, although the charge and discharge times of lithium batteries are much higher than those of nickel-hydrogen nickel-cadmium and lead-acid batteries, due to the difference in the capacity of lithium batteries, long-term charging and discharging, and differences in the ambient temperature of use, the battery will continue to age and the capacity will decrease. That is, there is a relatively large reduction from the initial nominal capacity, especially for high-current fast-charge batteries. The reduction of battery capacity will lead to a reduction in the working time and battery life of users when using electronic devices, and the power display will also produce obvious deviations.

In addition, the existing mobile devices basically rely on users to subjectively judge the performance of the battery, and do not have a prompt function for battery capacity aging, and there is no clear prompt information.

Therefore, how to accurately detect the performance of the battery has become a technical problem to be solved urgently.

In any of the above-mentioned technical solutions, preferably, the predetermined power percentage is one or more; the battery performance detection device 200 further includes: a threshold value setting unit 208, which is used to set the The received threshold setting command is used to set the first predetermined percentage, predetermined power percentage and second predetermined percentage for the battery; the initial setting unit 210 is used to obtain the initial capacity of the battery according to the received initial setting command during the first charging process of the battery Initial charging parameters at values and predetermined charge percentages.

In this technical solution, there are one or more predetermined power percentages, that is to say, the difference between the real-time charging parameter at one predetermined power percentage and the initial charging parameter can be selected to be detected, or the difference between multiple predetermined power percentages can be detected separately. The difference between the real-time charging parameters and the initial charging parameters. In the latter case, it can be set to determine battery aging only when all the detection results are yes, or it can be set to determine battery aging when at least one of the detection results is yes. Through this technical solution, the battery performance detection and prompting solution is more flexible and practical, and the required setting can be selected according to the actual situation of the user or the terminal.

Fig. 3 shows a block diagram of a terminal according to an embodiment of the present invention.

As shown in FIG. 3, a terminal 300 according to an embodiment of the present invention includes the battery performance detection device 200 shown in FIG. 2, therefore, the terminal 300 has the same technical effect as that of the battery performance detection device 200 shown in FIG. , which will not be repeated here.

Fig. 4 shows a flow chart of an initial setting method for battery performance detection according to an embodiment of the present invention.

As shown in FIG. 4, the initial setting method for battery performance detection according to an embodiment of the present invention includes the following steps:

Step 402, judge whether the current power of the battery is zero, if the judgment result is no, go to step 404, if the judgment step is yes, it means that the initial setting step can be entered, and go to step 406.

Step 404, charging normally.

Step 406, enable the charging information recording function, and record the charging information through software or hardware fuel gauge.

Step 408, recording the charging parameters when the battery capacity reaches 10%.

Step 410, for every 10% increase in the battery capacity value, record the corresponding charging parameters once.

Step 412, judging whether the battery capacity reaches 100%, if the judging result is yes, go to step 414, and if judging step is no, go back to step 410.

Step 414, saving the charging parameters corresponding to each battery capacity value.

Step 416, save the current battery capacity value.

In this technical solution, the standard capacity of each battery of the mobile device is the same, but there are individual differences, so the user needs to automatically test and save the above parameters when the device is charged for the first time. After the measurement and calculation of the initial capacity of the built-in battery of the mobile terminal, it can be saved in the mobile phone memory as the initial capacity value of the battery, and the parameters such as the charging voltage, charging current, and power node time of each battery charging point can be saved to the mobile phone. stored in memory as initial charging parameters. After completing the initial setting of the above-mentioned capacity value and charging parameters, the performance test of the battery itself can be carried out.

The first charging of the user's new mobile phone is divided into two situations. One is that the user's battery has run out of power and the power is 0%, and the other is that the battery power is random; if the power is not 0%, then Charge according to the normal charging process and end. When the power is judged to be 0%, start the lithium battery capacity and initial power point parameter test, and record the first complete charging information of the mobile phone.

The mobile phone starts the internal fuel gauge to calculate the battery charging power. The mobile phone fuel gauge is divided into two types. One is the hardware type that is measured by the chip. This type of fuel gauge has high accuracy. The second is the software type. Calculate the charging current and time and update the battery meter. For example, if the charging current is 1A and the charging time is 30 minutes, then the calculated battery capacity is 500mAh.

When the charging capacity reaches 10%, the software records the charging current and battery voltage, such as: charging current 1A, battery voltage 3.6V.

When the charging capacity increases by 10%, repeat the recording of the above charging current and battery voltage information.

When the charging power reaches 100%, the battery charging is completed, and the charging current and battery voltage information of each group with the power between 10% and 90% is saved to the mobile phone memory.

At the same time, it is necessary to save the battery capacity value recorded by the fuel gauge to the mobile phone memory. Since the capacity of each battery is not exactly the same, each battery needs to be tested and saved separately.

Fig. 5 shows a flowchart of a method for detecting battery performance according to another embodiment of the present invention.

Step 502, judging whether the current power of the battery is zero, if the judging result is yes, go to step 504, and if the judging step is no, go to step 512.

Step 504, turn on the software or hardware fuel gauge.

Step 506, charging to 100% battery power value.

Step 508, save the battery power value.

Step 510, judge whether the battery power value is less than or equal to 80% of the initial power value, if the judgment result is yes, enter step 522, if the judgment step is no, determine that the battery is not aging, and end the process.

Step 512, recording the real-time charging parameters when the battery capacity reaches 10%.

Step 514, for every 10% increase in the battery capacity, record the corresponding real-time charging parameters.

Step 516, judging whether the battery capacity reaches 100%, if the judging result is yes, go to step 518, and when judging step is no, go back to step 514.

Step 518, save the real-time charging parameters corresponding to each battery capacity percentage.

Step 520, judging whether at least one set of real-time charging parameters and the corresponding initial charging parameters with the same percentage of battery capacity have an increase value greater than or equal to 10%, when the judging result is yes, enter step 522, when the judging step is no, determine The battery is not aging, end the process.

Step 522, prompting that the battery is aging. In addition, when it is detected that the battery is not aging, a prompt can also be issued.

Specifically, it can be judged first whether the power of the battery is 0%. When the power is 0%, start the software or hardware fuel gauge test method to calculate the battery charging power. Compared with the initial battery capacity value, if it decreases by a certain percentage relative to the initial value, such as 15%, the terminal prompts the user that the battery capacity has decreased by 15%, prompting the user to replace the battery.

When the power is not 0%, it will enter the judgment of the charging voltage, current, time and other parameters of each power point of the battery. When the above-mentioned charging parameters recorded are compared with the initially stored parameter values of each power point, When the time is reduced by a certain percentage compared with the initial value, such as 10%, the mobile terminal prompts that the battery is aging and the capacity is reduced, and can prompt replacement.

The reason for battery aging is that the internal resistance of the battery increases. When the power drops, the corresponding charging current will decrease, the time will decrease, and the voltage will increase. For example, when the original power is 50%, the battery voltage is 3.8V, and the charging current is 1A, charging from 40% to 50% % takes 20 minutes, when the battery is aged, the parameters recorded to be 50% are the battery voltage is 3.95V, the charging current is 0.8A, and it takes 15 minutes to charge from 40% to 50%.

In general, the purpose of the present invention is to effectively detect the performance of the battery, so that users can know the life cycle of the product battery in a timely manner, quantify the aging condition and life time of the battery, and suggest replacement batteries in time, so as to improve the battery life and experience of the product Spend.
