[0042] The example embodiments will be described in detail herein with reference to the accompanying drawings. When the following description refers to accompanying drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The following description of example embodiments is not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0043] It should be noted that all actions of acquiring signals, information or data in the present disclosure are performed with authorization from the corresponding device owner.

[0044] It is also found in the process of presenting the present disclosure that, for the case where no coulomb meter or the like is used to calculate the battery electric quantity, the related art can be used to obtain a rough mapping from voltage to electric quantity, but the electric quantity is usually divided into three segments, and when the battery load is large, i.e., the battery current is small, the change of the battery electric quantity will appear a more obvious jump. It can be seen that the way of obtaining the battery electric quantity in the related art is too simple and rough, and the battery electric quantity cannot be accurately obtained, resulting in poor user experience.

[0045] To solve the above problems, the disclosure provides a power determination method, device, equipment, storage medium and chip. The terminal device involved in the disclosure can also be called a terminal or a computer device, which can include but is not limited to, for example, a smart phone, a wearable device (personal hub), a personal or mobile multimedia player, a personal digital assistant, a laptop, a tablet computer, a smart book, a palm computer, or other electronic devices with communication functions.

[0046] Please refer to Figure 1 It is a flowchart of a power determination method according to an exemplary embodiment. As shown in the method, the method is applied to a terminal device, and the method can include the following implementation steps: Figure 1

[0047] S101, obtain the current working parameter of the target battery, the current working parameter including the current battery voltage and the battery performance parameter, the battery performance parameter including the current battery internal resistance and / or the current battery temperature.

[0048] The current working parameter (or battery working parameter) of the battery in the disclosure can refer to the relevant working parameter involved in the description of the battery working, which can include but is not limited to, for example, the battery voltage, the performance parameter of the battery or other battery description parameter information, etc. The performance parameter refers to the parameter information for describing the performance of the battery, which can include but is not limited to any one or a combination of more of the following: for example, the battery internal resistance, the battery temperature, the battery load, the battery current or other parameters for affecting the performance of the battery, etc.

[0049] The disclosure does not limit the specific implementation mode of the above-mentioned current working parameter, for example, it can directly read the corresponding working parameter of the battery in the terminal device, or it can be obtained by sampling calculation, etc. Taking the current battery voltage as an example of the above-mentioned current working parameter, in order to ensure the accuracy of the power determination, the above-mentioned current battery voltage involved in the disclosure can refer to the average voltage of the target battery working in a preset period. In actual application, the disclosure can obtain the real-time voltage of the target battery in a preset period, and then average the real-time voltage to obtain the above-mentioned current battery voltage.

[0050] ​In some optional embodiments, to further improve the accuracy of the power determination, the disclosure can increase the number of sampling points, that is, increase the number of sampling points of the real-time voltage collected in the above-mentioned preset period, to obtain a plurality of real-time sampling voltages. Then a preset smoothing algorithm is used to smooth and average process these sampling voltages to obtain the above-mentioned current battery voltage, that is, the above-mentioned current battery voltage is obtained after the smoothing and average process of the plurality of sampling voltages in the above-mentioned preset period. In this way, the power determination can be more smooth, and the situation of large voltage fluctuation and repeated jump of power can be avoided.

[0051] S102, determining the power based on the M power mapping tables obtained by pre-modeling and the current working parameters to obtain the current battery power of the target battery, the power mapping table comprising a one-to-one mapping relationship between the battery voltage and the battery power, and M being a positive integer.

[0052] The above-mentioned power mapping table of the disclosure is obtained in advance by the system or the user according to the actual demand through the mapping table modeling. The power mapping table can be a charging (power) mapping table, that is, a voltage-power mapping table representing the target battery in the charging state; or a discharging (power) mapping table, that is, a voltage-power mapping table representing the target battery in the discharging state. The above-mentioned power mapping table can comprise one or more mapping relationships, and the mapping relationship is a one-to-one mapping between the battery voltage and the battery power. How to obtain the above-mentioned power mapping table will be described in detail below. The disclosure does not limit the specific implementation of the above-mentioned power determination, for example, it can be specifically referred to the related introduction in the embodiments of the disclosure shown below. Figure 2

[0053] By implementing the embodiments of the disclosure, the terminal device obtains the current working parameters of the target battery, the current working parameters comprising the current battery voltage and the battery performance parameters, the battery performance parameters comprising the current battery internal resistance and / or the current battery temperature; determines the power based on the M power mapping tables obtained by pre-modeling and the current working parameters to obtain the current battery power of the target battery, the power mapping table comprising a one-to-one mapping relationship between the battery voltage and the battery power, and M being a positive integer. As can be seen, in the case of limited battery information, the disclosure can also use the mapping table to obtain an accurate current battery power. In this way, the technical problem that the accurate battery power cannot be obtained according to the current battery voltage in the related art can be solved. Thus, it is beneficial to improve the accuracy of the power determination.

[0054] Please refer to Figure 2 is a flow diagram of another power determination method according to an exemplary embodiment. As Figure 2 The method shown can be applied to the terminal device, and the method can comprise the following implementation steps:

[0055] ​S201, obtain a current working parameter of a target battery. Wherein, the related introduction of step S201 can correspond to the related introduction of step S101 in the foregoing Figure 1 embodiment, which will not be repeated here.

[0056] S202, obtain a first battery voltage.

[0057] The first battery voltage in the present disclosure can refer to the last battery voltage before the current battery voltage. The first battery voltage can also refer to the average value of the battery voltage before a preset time, for example, the average voltage of the battery during the last period of time which has the same length as the preset period of time. The first battery voltage can correspond to the related introduction of the current battery voltage, which will not be repeated here.

[0058] S203, determine a target mapping table matched with the current working parameter from M power mapping tables based on the first battery voltage and the current working parameter. The target mapping table includes a charging mapping table or a discharging mapping table. The charging mapping table is the power mapping table of the target battery in the charging state, and the discharging mapping table is the power mapping table of the target battery in the discharging state.

[0059] The present disclosure does not limit the specific determination implementation of the target mapping table. For example, the present disclosure can select N candidate mapping tables matched with the first battery voltage and the current battery voltage from M power mapping tables. The N candidate mapping tables have the same type, i.e., they are all charging mapping tables or discharging mapping tables. N is a positive integer less than or equal to M. In a specific implementation, the present disclosure can determine the N candidate mapping tables according to the size relationship between the first battery voltage and the current battery voltage. Specifically, when the first battery voltage is greater than the current battery voltage, it means that the voltage decreases, and at this time, the candidate mapping table can be a discharging mapping table. Conversely, when the first battery voltage is less than or equal to the current battery voltage, it means that the voltage increases or remains unchanged, and at this time, the candidate mapping table can be a charging mapping table. After obtaining the N candidate mapping tables, the present disclosure can find a target mapping table matched with the battery performance parameter (such as the current battery internal resistance or the current battery temperature) from the N candidate mapping tables.

[0060] S204, find a battery remaining power matched with the current battery voltage in the target mapping table and determine it as the current battery power. After obtaining the target mapping table, the present disclosure can find a battery remaining power matched with the current battery voltage from the target mapping table by table lookup and determine it as the current battery power of the target battery.

[0061] Based on the foregoing two embodiments, some optional embodiments related to the present disclosure are introduced below.

[0062] In an optional embodiment, after obtaining the current battery power, the disclosure can also process some special cases of the battery, such as voltage rebound or sudden drop caused by charge-discharge switching or load switching. In specific implementation, the disclosure can also obtain the current working state of the target battery, which can include a charging state or a discharging state. The specific implementation of the disclosure for obtaining the above-mentioned current working state is not limited, for example, it can be obtained by obtaining the working state of the terminal charging chip. When the working state is used to indicate charging for the terminal battery, the current working state of the battery is charging state; otherwise, the current working state of the battery is determined to be discharging state.

[0063] After obtaining the above-mentioned current working state, the current battery power can be displayed based on the above-mentioned current working state. In specific implementation, the disclosure can determine whether the above-mentioned current working state and the battery working state corresponding to the above-mentioned target mapping table are the same. If they are the same, it means that the determination method of the above-mentioned current battery power is correct, and the above-mentioned current battery power can be normally displayed. Otherwise, if they are different, it means that the determination method of the above-mentioned current battery power is incorrect, that is, the determination of the above-mentioned target mapping table is wrong, at this time the battery power can be inhibited from increasing, and the above-mentioned current battery power can be prohibited from being displayed. Alternatively, the disclosure can still display the battery remaining power corresponding to the first battery voltage, and not display the above-mentioned current battery power.

[0064] For example, when the above-mentioned current working state is a charging state, and the battery working state corresponding to the above-mentioned target mapping table is a discharging state, that is, due to the terminal device currently being in a charging state, the battery voltage should increase; and based on the determination indication of the above-mentioned target mapping table, the first battery voltage is greater than the current battery voltage, that is, the battery voltage actually used decreases, indicating that the battery power consumption is greater than the charging, at this time the battery power should be inhibited / limited from increasing, to prevent voltage fluctuation and abnormal power, and the above-mentioned current battery power is not displayed.

[0065] For another example, when the above-mentioned current working state is a discharging state, and the battery working state corresponding to the above-mentioned target mapping table is a charging state, that is, the terminal device is currently in a discharging state, the battery voltage should decrease; and based on the determination indication of the above-mentioned target mapping table, the first battery voltage is less than or equal to the current battery voltage, that is, the battery voltage actually used increases or remains unchanged, in this case, the battery load may decrease, and voltage rebound may occur, at this time the battery power should be inhibited / limited from increasing, to avoid voltage rebound phenomenon or virtual power phenomenon, which is beneficial to improve user experience. And the current battery power obtained by using the above-mentioned charging mapping table (target mapping table) is also not accurate, and the above-mentioned current battery power should be prohibited from being displayed.

[0066] The following describes embodiments of the above power mapping table. The above power mapping table can be obtained by modeling in advance. In a specific implementation, the present disclosure can obtain the charging and discharging data of the target battery under different historical performance parameters, which can at least include historical battery voltage, and can also include historical battery power, battery charging and discharging characteristic (curve) data or other customized data, etc. Optionally, when the above charging and discharging data includes the above historical battery voltage, the charging and discharging data can also be referred to as charging and discharging characteristic data (or charging and discharging characteristic curve data). The above historical performance parameters can include, but are not limited to, for example, historical battery current, historical battery temperature, and historical battery internal resistance of the target battery, or other parameters for affecting battery performance, etc.

[0067] Further, the present disclosure can model and convert the voltage and power based on the charging and discharging data under different historical performance parameters, convert the charging and discharging characteristic data into a voltage and power mapping table, and obtain M power mapping tables obtained by modeling, which can include a charging (power) mapping table and a discharging (power) mapping table. For example, please refer to Figure 3 is a schematic diagram of power mapping table modeling according to an exemplary embodiment. As shown in Figure 3 , taking the above historical performance parameters including battery temperature and battery current as an example, the present disclosure can obtain the charging and discharging characteristic (curve) data of the target battery under different temperatures and different currents (i.e. different loads), and convert these charging and discharging characteristic data into corresponding power mapping tables (i.e. charging and discharging mapping tables) through modeling. Wherein, a combination of a pair of battery current and temperature corresponds to a charging and discharging power mapping relationship, which can include a charging mapping table and a discharging mapping table. When the battery temperature and the battery current change, the corresponding charging and discharging mapping table can be dynamically switched to. As shown in the figure, when a combination of a pair of battery temperature and battery power is input, the corresponding charging and discharging mapping table can be found by looking up the table.

[0068] It can be understood that when the number of combinations of battery temperature and battery current is sufficient and the division is sufficient, the above power mapping table will also be more and more, which can make the result of power determination more accurate / precise. In this case, the present disclosure will only use the current sensor to obtain the battery current in the modeling stage of the mapping table, and will not use devices such as coulomb meter, current sensor, etc. in subsequent other stages. It also shows that the present disclosure can obtain a relatively accurate current battery power even in the case of limited battery information.

[0069] It can be seen that the present disclosure can obtain the power mapping table according to the battery performance parameters without the power meter or the current sensor and the like, and switch the corresponding target mapping table according to the dynamic change of the performance parameters in working, so as to avoid the jump phenomenon such as virtual power, low power consumption, small power consumption, and power rebound. At the same time, the mapping relationship in the power mapping table is more accurate, and the current battery power can be obtained more truly and accurately without increasing the power meter and the current sensor, thereby saving the cost. In a specific implementation, the terminal device of the present disclosure can obtain the current working parameters of the target battery, the current working parameters including the current battery voltage and the battery performance parameters, the battery performance parameters including the current battery internal resistance and / or the current battery temperature; the power is determined based on the M power mapping tables obtained by pre-modeling and the current working parameters, to obtain the current battery power of the target battery, the power mapping table including the one-to-one mapping relationship between the battery voltage and the battery power, and M is a positive integer. It can be seen that in the case of limited battery information, the present disclosure can also use the mapping table to obtain the accurate current battery power. In this way, the technical problem that the accurate battery power cannot be obtained according to the current battery voltage in the related art can be solved. Thus, the accuracy of power determination is improved.

[0079] determine the target mapping table from the N candidate mapping tables based on the battery performance parameter;

[0080] wherein, when the first battery voltage is greater than the current battery voltage, the candidate mapping table is the discharging mapping table; and when the first battery voltage is less than or equal to the current battery voltage, the candidate mapping table is the charging mapping table.

[0087] In some embodiments, the current battery voltage is an average voltage of the target battery within a preset time period.

[0088] In some embodiments, the current battery voltage is obtained by smoothing and averaging a plurality of sampling voltages in the preset time period.

[0089] In some embodiments,

[0090] The acquisition module 401 is further configured to acquire charging and discharging data of the target battery under different historical performance parameters, the charging and discharging data including historical battery voltage and historical battery capacity.

[0091] The processing module 402 is further configured to perform voltage-capacity modeling conversion based on the charging and discharging data under different historical performance parameters to obtain M battery capacity mapping tables.
