In the related art, the SOH is monitored mainly by acquiring the corresponding SOH through the cycle number and the internal resistance of the battery. However, this monitoring method only considers part of the battery characteristics, but does not consider the working condition of the battery, so the accuracy of the monitored SOH is not high, that is, the current state of health of the battery cannot be truly reflected, and the battery cannot be replaced in time or replaced unnecessarily.
Based on the technical problem, the method improves the acquisition of the battery health state information, namely, the current accumulated energy of the battery is acquired mainly by acquiring the current voltage data and current data of the battery and according to the voltage data and the current data, the corresponding relation between the preset accumulated energy and the battery health state information is inquired according to the current accumulated energy of the battery and the acquired battery health state information determined by monitoring the battery last time, the current health state information of the battery is determined, and the battery is correspondingly processed when the battery health state information is determined to be smaller than a battery safety threshold value. 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 condition of the working condition of the battery, so that the current health state information of the battery can be accurately determined in real time based on the current accumulated energy and the battery health state information determined by monitoring the battery last time, and the battery is correspondingly processed when the battery health state information is smaller than the battery safety threshold.
Fig. 1 is a flowchart of a battery-based processing method according to an embodiment of the present disclosure, and as shown in fig. 1, the method of the present embodiment may include:
s101, acquiring current voltage data and current data of the battery, and acquiring current accumulated energy of the battery according to the voltage data and the current data.
S102, according to the current accumulated energy of the battery and the acquired battery health state information determined by monitoring the battery last time, inquiring the corresponding relation between the preset accumulated energy and the battery health state information, and determining the current health state information of the battery.
In the embodiment, a battery is arranged in the mobile terminal, voltage data and current data on the battery can be detected no matter how the battery works, and the current accumulated energy of the battery is acquired based on the detected voltage data and current data. The detection of the battery is periodic, for example, every 1 minute.
In addition, the accumulated energy refers to the energy accumulated since the battery is started to be used for multiple operations, for example, during the charging or discharging process, and has a certain corresponding relationship with the SOH value of the battery health state information, and according to the obtained current accumulated energy of the battery and the SOH value determined by monitoring the battery last time, the current monitoring result, that is, the current SOH value of the battery, can be obtained through a certain calculation mode based on the corresponding relationship between the accumulated energy and the SOH value.
And S103, when the battery health state information is determined to be smaller than the battery safety threshold, correspondingly processing the battery.
In this embodiment, the service life of each battery to be used is long, and how to accurately obtain the SOH value of the battery is critical to whether the mobile terminal to which the battery belongs can normally operate, so that after the current SOH value of the battery can be accurately obtained, whether the battery can maintain the stable operation of the mobile terminal can be judged according to the SOH value, and when the current SOH value of the battery cannot be maintained, a prompt message is generated to remind the mobile terminal, and a user using the mobile terminal can timely detect or replace the battery, thereby preventing other problems caused by the non-operation or failure of the battery to the operation of the mobile terminal.
In some embodiments, the monitoring of the battery health status may be periodic, and when each period reaches the monitoring time, the steps S101-S102 are executed, and the step S103 is not executed until the monitoring result determines that the battery health status information is smaller than the battery safety threshold value.
In some implementations, the construction basis data of the preset correspondence between the accumulated energy and the battery health status information is derived from the battery own attribute information. The self attribute information of the battery includes parameters such as the specification and the charge and discharge performance of the battery, for example: terminal voltage curve, cycle life, etc. Based on the self attribute information, the correspondence between the acquired battery accumulated energy and the battery SOH value can be calculated. For example, from the cycle life data, it can be known that after 10 complete charge and discharge cycles, the SOH value is reduced from 71% to 70%, and then the SOH value is calculated from the terminal voltage curve, and the cumulative total energy is 1kWH by the end of the 10 complete charge and discharge cycles, so that the corresponding relationship between the cumulative energy and the SOH value can be known. It will be appreciated that the same effect can be obtained by other similar data using the battery own attribute information.
In addition, the corresponding relationship can be further updated based on factors such as the current use environment of the battery, so as to better conform to the corresponding relationship of the current battery.

The working environment of the battery is different, so that the voltage or the current may have an unstable state in the charging or discharging process, and experiments show that the state of the voltage or the current which is relatively stable is more accurate for calculating the SOH value of the battery. For example, for a battery in a new energy automobile, the voltage and the current of the charging pile in the charging process are more stable than those in the discharging process of driving, that is, the working state information of the battery can be determined to be the charging state.
