[0082] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings in the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present application belong to the scope of protection of the present application.

[0083] In the related art, the monitoring method for SOH mainly obtains the corresponding SOH by means of the battery cycle count and the battery internal resistance. However, this monitoring method only considers some battery characteristics and does not take into account the battery operating conditions. Therefore, the accuracy of the monitored SOH is not high, that is, it cannot truly reflect the current health state of the battery, which in turn leads to the inability to replace the battery in a timely manner or unnecessary replacements.

[0084] Based on this technical problem, the present application improves the acquisition of battery health state information. That is, mainly by acquiring the current voltage data and current data of the battery and based on the voltage data and current data, the current cumulative energy of the battery is obtained. According to the current cumulative energy of the battery and the battery health state information determined by the previous battery monitoring, the preset corresponding relationship between the cumulative energy and the battery health state information is queried to determine the current health state information of the battery. When it is determined that the battery health state information is less than the battery safety threshold, corresponding processing is performed on the battery. Since the current cumulative energy of the battery can be obtained based on the acquired voltage data and current data, that is, the current cumulative energy of the battery can be obtained in real time according to the battery working conditions, and thus the current health state information of the battery can be determined in real time and accurately based on the current cumulative energy and the battery health state information determined by the previous battery monitoring. Furthermore, when the battery health state information is less than the battery safety threshold, corresponding processing is performed on the battery.

[0085] Figure 1 The flowchart of the processing method based on the battery provided by an embodiment of the present application is as Figure 1 shown. The method of this embodiment may include:

[0086] S101. Acquire the current voltage data and current data of the battery, and based on the voltage data and current data, acquire the current cumulative energy of the battery.

[0087] S102. According to the current cumulative energy of the battery and the battery health state information determined by the previous battery monitoring, query the preset corresponding relationship between the cumulative energy and the battery health state information to determine the current health state information of the battery.

[0088] In this embodiment, a battery is provided in the mobile terminal. Regardless of the working state of the battery at this time, the voltage data and current data on the battery can be detected, and based on the detected voltage data and current data, the current cumulative energy of the battery is acquired. Among them, the detection of the battery is periodic. For example, the detection is performed once every 1 minute.

[0089] In addition, the cumulative energy refers to the energy accumulated during multiple operations of the battery since it started to be used, such as during the charging or discharging process. It has a certain corresponding relationship with the state of health (SOH) value of the battery. According to the currently acquired cumulative energy of the battery and the SOH value determined by the previous battery monitoring, based on the corresponding relationship between the cumulative energy and the SOH value, through a certain calculation method, the monitoring result this time, that is, the current SOH value of the battery, can be obtained.

[0090] S103. When it is determined that the battery health state information is less than the battery safety threshold, perform corresponding processing on the battery.

[0091] In this embodiment, the batteries used all have their service lives. How to accurately obtain the SOH value of the battery is crucial for whether the mobile terminal to which the battery belongs can work properly. Therefore, when the current SOH value of the battery can be accurately obtained, the SOH value can be used to determine whether the battery can maintain the stable operation of the mobile terminal. When the battery cannot maintain the stable operation of the mobile terminal, a prompt message is generated to remind the mobile terminal and the user using the mobile terminal to detect or replace the battery in time, thereby preventing other problems from occurring to the operation of the mobile terminal due to the battery not working or malfunctioning.

[0092] In some embodiments, the monitoring of the battery health state can be periodic. When the monitoring moment arrives at each period, steps S101 - S102 are executed until it is determined in a certain monitoring result that the battery health state information is less than the battery safety threshold, then S103 is executed.

[0093] In some implementation manners, the construction basic data of the preset corresponding relationship between the cumulative energy and the battery health state information comes from the battery's own attribute information. The battery's own attribute information includes parameters such as the battery's specifications and charge-discharge performance, for example: terminal voltage curve, cycle life and other data. Based on this own attribute information, the corresponding relationship between the battery cumulative energy and the battery SOH value 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%. Then, through the terminal voltage curve, it can be calculated that as of the end of these 10 charge-discharges, the cumulative total energy is 1 kWH. Thus, the corresponding relationship between the cumulative 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.

[0094] In addition, the corresponding relationship can be further updated based on factors such as the current usage environment of the battery to better conform to the current corresponding relationship of the battery.

[0095] Figure 2 The flowchart of the processing method based on the battery provided by another embodiment of the present application is as Figure 2 shown. The method of this embodiment may include:

[0096] S201. Obtain the current voltage data and current data of the battery, and obtain the current cumulative energy of the battery according to the voltage data and the current data.

[0097] In this embodiment, the specific implementation process of step S201 can refer to the relevant description of the Figure 1 shown embodiment, and will not be elaborated here.

[0098] S202. Obtain the working state information of the battery; wherein, the working state information includes one of the following:

[0099] Charging state, discharging state, charging and discharging state.

[0100] Different working environments of the battery may cause unstable voltage or current during the charging or discharging process. Through experiments, it is found that the relatively stable state of voltage or current is more accurate for calculating the SOH value of the battery. For example, for the battery in a new energy vehicle, the voltage and current during the charging process of the charging pile are more stable than those during the discharging process of driving. That is, it can be determined that the working state information of this battery is the charging state.

[0101] S203. According to the current cumulative energy of the battery, the battery health state information determined by the previous monitored battery, and the working state information of the battery, query the preset corresponding relationship between the cumulative energy and the battery health state information, and determine the current health state information of the battery.

[0102] After adding the parameter of the working state information, the corresponding cumulative energy is exactly the energy consistent with the working state information. Still taking the battery in the above new energy vehicle as an example, the cumulative energy corresponding to the charging state refers to the energy accumulated during multiple charging processes of the battery since it started to be used. It has a certain corresponding relationship with the SOH value of the battery health state information. According to the currently obtained cumulative energy of the battery, the SOH value determined by the previous monitored battery, and the working state information, based on the corresponding relationship between the cumulative energy and the SOH value, through a certain calculation method, the monitoring result this time, that is, the current SOH value of the battery, can be obtained.

[0103] S204. When it is determined that the battery health state information is less than the battery safety threshold, perform corresponding processing on the battery.

[0104] In this embodiment, the specific implementation process of step S204 can refer to Figure 1 the relevant description of the shown embodiment, which will not be elaborated here.

[0105] The processing method based on the battery provided in this embodiment will also obtain the working state information of the battery as a condition for querying the corresponding relationship between the cumulative energy of the battery and the battery health state information, realizing more accurate calculation and monitoring of the current health state information of the battery, so as to more timely perform corresponding processing on the battery when the battery health state is less than the safety threshold.

[0106] In some specific implementation manners, the way to obtain the current cumulative energy of the battery can be to obtain the voltage data and current data of the battery in real time, calculate the electric energy in real time, and accumulate to obtain the cumulative energy during the two monitoring periods. The specific calculation formula is as follows:

[0107] E(t) = E(t - 1) + U * I * T

[0108] Where t > 0, E(t) is the cumulative energy at time t, E(t - 1) is the cumulative energy at time t - 1, U is the voltage data at time t, I is the current data at time t, and T is the cumulative time from time t - 1 to time t. E(0) = 0. For example, if the time interval between two measurements is determined to be 1 hour, and during this period, the cumulative time T for calculating the current cumulative energy is 1 minute, then the cumulative energy E(1) at the 1st minute = U * I * T, and the cumulative energy E(2) at the 2nd minute = E(1) + U * I * T.

[0109] In some embodiments, the voltage data includes one of the following: terminal voltage, estimated electromotive force, and estimated open - circuit voltage.

[0110] Among them, the terminal voltage is the working voltage of the battery, that is, the voltage measured in real - time during the charge - discharge process; the estimated open - circuit voltage is the voltage of the battery under no - load conditions, that is, ignoring the energy consumption of the load; the estimated electromotive force is the voltage ignoring the internal resistance of the battery. Correspondingly, for the terminal voltage curve listed in the previous example, the corresponding open - circuit voltage curve and electromotive force curve can be obtained through calculation, and the corresponding cumulative energy values can also be obtained.

[0111] In some other embodiments, the cumulative energy is set as the energy consumed by the battery, and the corresponding voltage data is the voltage data corresponding to the internal resistance of the battery, which is reflected as the difference between the battery terminal voltage and the estimated open - circuit voltage, or the difference between the battery terminal voltage and the estimated electromotive force. Correspondingly, to obtain the current voltage data of the battery, it includes: obtaining the terminal voltage of the battery and the estimated open - circuit voltage of the battery, and taking the difference between the terminal voltage of the battery and the estimated open - circuit voltage of the battery as the current voltage data of the battery; or, obtaining the terminal voltage of the battery and the estimated electromotive force of the battery, and taking the difference between the terminal voltage of the battery and the estimated electromotive force of the battery as the current voltage data of the battery.

[0112] In some specific embodiments, the method for determining the current health state of the battery is as follows: according to the battery health state information determined by the previous battery monitoring, query the preset correspondence between the cumulative energy and the battery health state information to determine the previous cumulative energy corresponding to the battery health state information determined by the previous battery monitoring; calculate the current cumulative energy based on the previous cumulative energy and the current cumulative energy; query the correspondence according to the current cumulative energy to determine the health state information corresponding to the current cumulative energy; determine the health state information as the current health state information of the battery.

[0113] In some other embodiments, the method for determining the current health status information of the battery is as follows: according to the battery health status information determined in the last battery monitoring, query the preset corresponding relationship between the cumulative energy and the battery health status information, and determine the relationship between the attenuation rate of the battery health status information determined in the last battery monitoring and the change amount of the cumulative energy; according to the relationship between the attenuation rate of the battery health status information determined in the last battery monitoring and the change amount of the cumulative energy, and the current cumulative energy of the battery, calculate the change amount of the battery health status information; according to the change amount of the battery health status information, determine the current health status information of the battery.

[0114] Figure 3 The flowchart of the processing method based on the battery provided in another embodiment of the present application is as Figure 3 shown. The method of this embodiment may include:

[0115] S301. Obtain the current voltage data and current data of the battery, and obtain the current cumulative energy of the battery according to the voltage data and the current data.

[0116] In this embodiment, the specific implementation process of step S301 may refer to the relevant description of the Figure 1 shown embodiment, which will not be elaborated here.

[0117] S302. Obtain the ambient temperature at which the battery is currently located.

[0118] Different temperatures in the battery working environment will lead to different battery losses. The more extreme the ambient temperature is, the faster the battery will be damaged.

[0119] S303. According to the current cumulative energy of the battery, the battery health status information determined in the last battery monitoring that has been obtained, and the ambient temperature, query the preset corresponding relationship between the cumulative energy and the battery health status information, and determine the current health status information of the battery.

[0120] After adding the parameter of ambient temperature, the corresponding relationship between the cumulative energy and the SOH value specifically also includes the corresponding relationships at different ambient temperatures. According to the obtained current cumulative energy of the battery, the SOH value determined in the last battery monitoring, and the ambient temperature, based on the corresponding relationship between the cumulative energy and the SOH value at the same ambient temperature, through a certain calculation method, the monitoring result this time, that is, the current SOH value of the battery, can be obtained.

[0121] S304. When it is determined that the battery health status information is less than the battery safety threshold, perform corresponding processing on the battery.

[0122] In this embodiment, the specific implementation process of step S304 may refer to the relevant description of the Figure 1 shown embodiment, which will not be elaborated here.

[0123] The battery-based processing method provided in this embodiment further obtains the working state information of the battery as a condition for querying the corresponding relationship between the battery's cumulative energy and the battery health state information, so as to more accurately calculate and monitor the current battery health state information, and facilitate more timely handling of the battery when the battery health state is less than the safety threshold.
