In the related art, the monitoring method for SOH is mainly to obtain the corresponding SOH through the number of battery cycles and the internal resistance of the battery. However, this monitoring method only considers some battery characteristics, but does not take into account the working conditions of the battery. Therefore, the accuracy of the monitored SOH is not high, that is, it cannot truly reflect the current state of health of the battery, which leads to The battery cannot be replaced in time or needlessly.

Based on this technical problem, the present application improves the acquisition of battery state of health information, that is, mainly by acquiring the current voltage data and current data of the battery and obtaining the current accumulated energy of the battery according to the voltage data and current data, according to the current accumulated energy of the battery.

Since the current accumulated energy of the battery can be acquired based on the acquired voltage data and current data, that is, the current accumulated energy of the battery can be acquired in real time according to the working conditions of the battery, so that the battery can be further determined based on the current accumulated energy and the last monitoring of the battery. The current state of health information of the battery is determined in real time and accurately, and then the battery is processed accordingly when the state of health information of the battery is less than the battery safety threshold.

FIG. 1 is a flowchart of a battery-based processing method provided by an embodiment of the present application. As shown in FIG. 1 , the method of this embodiment may include:

S101. Acquire current voltage data and current data of the battery, and acquire current accumulated energy of the battery according to the voltage data and current data.

S102 , according to the current accumulated energy of the battery and the obtained battery state of health information determined by the last monitored battery, query the corresponding relationship between the preset accumulated energy and the information of the battery state of health, and determine the current state of health information of the battery.

In this embodiment, the mobile terminal is provided with a battery. Regardless of the working state of the battery at this time, the voltage data and current data on the battery can be detected, and the battery can be obtained based on the detected voltage data and current data. Current cumulative energy. Wherein, the detection of the battery is periodic, for example, the detection is performed every 1 minute.

In addition, the accumulative energy refers to the accumulative energy of the battery that has been used for many times since the beginning of use, for example, during the charging or discharging process, which has a certain corresponding relationship with the SOH value of the battery's health status information. And the SOH value determined by the last monitoring battery, based on the corresponding relationship between the accumulated energy and the SOH value, through a certain calculation method, the monitoring result of this time, that is, the current SOH value of the battery can be obtained.

S103. When it is determined that the battery health state information is less than the battery safety threshold, perform corresponding processing on the battery.

In this embodiment, the used battery has its service life. How to accurately obtain the SOH value of the battery is very important to whether the mobile terminal to which the battery belongs can work normally. After the current SOH value of the battery is obtained, it can be judged whether the battery can maintain the stable operation of the mobile terminal according to the SOH value, and when the stable operation of the mobile terminal cannot be maintained, a prompt message is generated to remind the mobile terminal and use The user of the mobile terminal detects or replaces the battery in time, thereby preventing other problems caused to the operation of the mobile terminal due to the battery not working or failing.

In some embodiments, the monitoring of the state of health of the battery may be periodic, and when the monitoring time is reached in each cycle, steps S101-S102 are performed until a certain monitoring result determines that the state of health information of the battery is less than the battery safety threshold, Only execute S103.

Based on the self-attribute information, the corresponding relationship between the accumulative energy of the battery and the SOH value of the battery can be calculated and obtained. For example, through the cycle life data, it can be known that after 10 complete charge-discharge cycles, the SOH value drops from 71% to 70%, and then through the terminal voltage curve, it can be calculated that by the end of these 10 times of charge and discharge, The accumulated total energy is 1kWH, so the corresponding relationship between the accumulated energy and the SOH value can be known. It can be understood that the same effect can also be obtained by using other similar data of the battery's own attribute information.

The working environment of the battery is different, which may lead to an unstable state of the voltage or current during the charging or discharging process. It has been found through experiments that the relatively stable state of the voltage or current is more accurate for the calculation of the SOH value of the battery. For example, for a battery in a new energy vehicle, the voltage and current of the charging pile in the charging process are more stable than the voltage and current in the discharging process of driving, so the working state information of the battery can be determined as the charging state.

S203 , according to the current accumulated energy of the battery, the obtained battery state of health information determined by the last monitoring battery, and the working state information of the battery, query the corresponding relationship between the preset accumulated energy and the information of the battery state of health, and determine the current state of health information of the battery .
