[0044] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0045] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0046] The following, in conjunction with the accompanying drawings, describes in detail the battery power calculation method, battery power calculation device, electronic device and readable storage medium provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0047] The battery power calculation method provided in the embodiment of the present application can be executed by an electronic device or a functional module or functional entity in the electronic device that can implement the battery power calculation method. The battery power calculation method provided in the embodiment of the present application is described below using an electronic device as an example of the execution entity.

[0048] As shown in FIG3 , the battery can be used as a system, which may include a battery module, a battery protection board and corresponding protection metal-oxide-semiconductor (MOS), a power metering module, a sampling resistor, a charging module, and a discharging module.

[0049] Among them, the battery module is a module for storing electricity.

[0050] The function of the battery protection board and the corresponding protection MOS is to protect the battery module. When the battery module is in an abnormal state such as overcharge, over-discharge, overcurrent and short circuit, the protection MOS will be turned off, cutting off the path from the charging module and the discharging module to the battery module, thereby protecting the battery module.

[0051] The power measurement module obtains the battery voltage and battery current and calculates the battery power, including power initialization and power measurement at other times.

[0052] The charging module charges the battery module, and the discharging module draws power from the battery module to supply power to other modules.

[0053] The battery operating state may include a shutdown state and a charge and discharge state, and the charge and discharge state may include a charge state and a discharge state.

[0054] The battery operating status can be determined by detecting the status of the charging module and the discharging module. When the charging module is operating, the battery is determined to be in the charging state; when the discharging module is operating, the battery is determined to be in the discharging state; and when both the charging module and the discharging module are not operating, the battery is determined to be in the off state. The battery power calculation method provided in the embodiment of the application can be applied to a power meter module to calculate the battery power.

[0055] As shown in FIG1 , the method for calculating battery power includes steps 110 and 120 .

[0056] Step 110 : In response to the battery being in a charging state, when the battery voltage of the battery exceeds a first voltage threshold for a period exceeding a first duration threshold, obtaining first power data of the battery, and determining a target initial power of the battery based on the first power data.

[0057] The battery voltage is the actual output voltage of the battery when it is loaded, which is affected by the internal resistance of the battery.

[0058] The first voltage threshold is a preset voltage value, which may be the over-discharge release voltage of the battery protection board. The first time threshold is a preset time, which may be the over-discharge detection delay time of the battery protection board.

[0059] The power data is data obtained by calculating the battery voltage and battery current obtained in real time and used to represent the remaining storage capacity of the battery.

[0060] The first power data is power data obtained when the battery is in a charging state and the duration for which the battery voltage exceeds a first voltage threshold exceeds a first duration threshold.

[0061] In this embodiment, when the battery is in a charging state, it cannot be determined whether the battery protection board is in a protection state. In the charging state, the battery voltage is continuously detected. When it is detected that the battery voltage exceeds the first voltage threshold for a period of time exceeding the first time threshold, it can be determined that even if the battery protection board is in a protection state when the power is off, the battery protection board can be charged and turned on after charging and is in an unprotected state.

[0062] After the battery voltage of the battery exceeds the first voltage threshold for a period longer than the first time threshold, the acquired first power data is accurate power data.

[0063] In this embodiment, the target initial power is an accurate power, and the target initial power can be used as a benchmark for the power metering module, providing a basis for subsequent accurate real-time power metering.

[0064] The first power data may be used as the target initial power, or the target initial power may be obtained by calibrating the first power data.

[0065] Step 120: Calculate the real-time battery capacity based on the target initial capacity.

[0066] In this step, the battery's charge and discharge current and duration can be detected, and the battery's consumed or increased power can be calculated using the ampere-hour integration method. The battery's real-time power can be obtained by subtracting the consumed power from the target initial power or adding the increased power.

[0067] According to the battery power calculation method provided in the embodiment of the present application, by continuously detecting the battery voltage when the battery is in a charging state, when it is detected that the battery voltage of the battery exceeds the first voltage threshold for a period of time exceeding the first time threshold, it can be determined that even if the battery protection board was previously in a protection state, the battery protection board can be charged and is in an unprotected state after charging. The first power data obtained is accurate power data and can be used as the target initial power. The real-time power of the battery calculated based on the target initial power is more accurate.

[0068] In some embodiments, the battery is in a powered-off state before being in a charging state, and the method further comprises:

[0069] In response to the battery being in a power-off state, obtaining second battery power data;

[0070] Determining a target initial battery capacity based on the first battery capacity data includes:

[0071] The target initial power level is determined based on the first power level data and the second power level data, wherein the second power level data is power level data obtained when the battery is in a powered-off state.

[0072] It should be noted that when the battery is in the off state, no charging or discharging actions are performed, and it cannot be determined whether the battery protection board is in the protection state. If the battery protection board is in the unprotected state, the second power data is accurate data and can be used as the target initial power. If the battery protection board is in the protection state, the current battery voltage is only the floating charge accumulated, not the actual voltage of the battery. The calculated second power data is inaccurate and cannot be used as the target initial power.

[0073] A second initialization is performed according to the charge and discharge state after the shutdown state is converted, and the second power data is verified to determine whether the second power data is accurate. When the second power data is determined to be accurate, it can be used as the target initial power. When it is determined that the second power data is not accurate, the second power data can be calibrated or replaced with other accurate power data as the target initial power.

[0074] In this embodiment, when the battery is switched from a shutdown state to a charging state, it cannot be determined whether the battery protection board is in a protection state in the shutdown state. In the charging state, the battery voltage is continuously detected. When it is detected that the battery voltage exceeds the first voltage threshold for a time period exceeding the first time threshold, it can be determined that even if the battery protection board is in a protection state in the shutdown state, the battery protection board can be charged and turned on after charging and is in an unprotected state.

[0075] After the battery voltage of the battery exceeds the first voltage threshold for a period of time that exceeds the first time threshold, the first power data obtained is accurate power data. By comparing the first power data with the second power data, it can be determined whether the battery protection board is in a protection state in the shutdown state and whether the second power data is accurate, thereby determining whether the second power data is determined as the target initial power or the first power data is determined as the target initial power.

[0076] In some embodiments, determining the target initial power based on the first power data and the second power data includes:

[0077] Calculating the absolute value of the difference between the first power data and the second power data;

[0078] When the absolute value of the difference is greater than or equal to the first difference threshold, taking the first power data as the target initial power;

[0079] Alternatively, when the absolute value of the difference is smaller than the first difference threshold, the second power data is used as the target initial power.

[0080] Among them, the first difference threshold is a preset value, which can be comprehensively considered according to the errors of the battery internal resistance in the shutdown state, charging state and discharging state, and can be set to 5%, 10%, 20%, etc.

[0081] For example, the second power data is Pinit1, the first power data is Pinit2, and the absolute value of the difference Pinit_delta between the first power data and the second power data is calculated

[0082] Pinit_delta = |Pinit1 - Pinit2|

[0083] The first difference threshold is Pinit_threshold. If Pinit_delta >= Pinit_threshold, it is considered that the battery protection board in the shutdown state is in the protection state, and the calculated second power data Pinit1 is inaccurate, while the first power data Pinit2 is accurate. The first power data Pinit2 is used as the target initial power Pinit_final.

[0084] If Pinit_delta < Pinit_threshold, it is considered that the battery protection board in the shutdown state is not in the protection state, and the calculated second power data Pinit1 is accurate. Therefore, the second power data Pinit1 is used as the target initial power Pinit_final.

[0085] It should be noted that the battery internal resistance may introduce errors in the charging state, and the calculated first power data may have errors. If the difference between the first power data and the second power data is small, it means that the battery protection board is in the unprotected state in the shutdown state, and the second power data calculated in the shutdown state is accurate. At the same time, in the shutdown state, since the battery current is zero, the battery voltage is the battery terminal voltage, and the battery internal resistance does not need to be introduced, and the error of the battery internal resistance will not be introduced. Compared with the first power data, the second power data is more accurate, and the second power data is used as the target initial power.

[0086] In some embodiments, determining the target initial power of the battery based on the first power data includes:

[0087] Determining the first power data as the target initial power.

[0088] In this embodiment, when the battery is initially in the charging state, the first power data can be directly determined as the target initial power.

[0089] In some embodiments, the method further includes:

[0090] In response to the battery being in a discharging state, third power data of the battery is acquired, and the third power data is determined as the target initial power.

[0091] The third power data is power data obtained when the battery is in a discharging state.

[0092] In this embodiment, when the battery is in the discharging state, the discharge module will detect the battery voltage before turning on. The discharge module can only be turned on normally if the battery voltage is higher than the undervoltage threshold of the discharge module. In addition, the undervoltage threshold of the discharge module is generally higher than the protection voltage of the battery protection board. The fact that the discharge module is in the turned-on state indicates that the battery protection board is not in the protection state. The third power data directly obtained is accurate power data and can be used as the target initial power.

[0093] In some embodiments, the method further comprises:

[0094] In response to the battery being in a power-off state, obtaining second battery power data;

[0095] In response to the battery being switched from a shutdown state to a discharge state, the second power data is determined as the target initial power.

[0096] When the battery switches from the shutdown state to the discharge state, the discharge module will detect the battery voltage before turning on. The discharge module can only be turned on normally if the battery voltage is higher than the undervoltage threshold of the discharge module. In addition, the undervoltage threshold of the discharge module is generally higher than the protection voltage of the battery protection board. If the discharge module is in the turned-on state, it means that the battery protection board is not in the protection state. The second power data obtained in the shutdown state is accurate, and the second power data can be determined as the target initial power.

[0097] In some embodiments, the first power data is obtained by the following steps:

[0098] Get the battery voltage and battery current of the battery;

[0099] determining a battery terminal voltage of the battery based on the battery voltage and the battery current;

[0100] Based on the battery terminal voltage, first power data is determined.

[0101] Among them, the battery voltage is the actual output voltage of the battery when it is loaded, which is affected by the internal resistance of the battery. The battery current is the charging current or discharging current of the battery. The battery terminal voltage is the voltage of the battery when it is unloaded, reflecting the true electromotive force of the battery and is not affected by the battery current.

[0102] In this embodiment, the current flowing through the sampling resistor can be collected as the battery current, and the voltage on the side of the sampling resistor close to the battery module can be collected as the battery voltage. The battery voltage, battery current and battery internal resistance are calculated to obtain the battery terminal voltage.

[0103] For example, the battery voltage is Vbat, the battery current is Ibat, and the battery internal resistance is Rdc. The battery terminal voltage Vocv is calculated as Vocv=Vbat-Ibat*Rdc.

[0104] In this embodiment, a mapping relationship between the battery terminal voltage and the battery power level may be preset, and the obtained battery terminal voltage is substituted into the preset mapping relationship to obtain the first power level data.

[0105] In some embodiments, determining the first power data based on the battery terminal voltage includes:

[0106] Substitute the battery terminal voltage into the voltage-to-electricity mapping curve to obtain first electric quantity data.

[0107] The voltage-to-capacity mapping curve is a curve that describes the relationship between the battery terminal voltage and the battery capacity.

[0108] In this embodiment, the battery terminal voltage is substituted into the voltage-to-capacity mapping curve, and the corresponding first power data is calculated using a difference algorithm. A specific embodiment of a battery power calculation method is described below.

[0109] Under different battery operating conditions, power data is acquired in different ways or at different times, and a target initial power level is determined based on the power data in different ways under different battery operating conditions to ensure that the target initial power level is the accurate power level of the battery when it is not in a protection state. In this embodiment, the battery power calculation method is applied to the power meter module, which can achieve power initialization during the process of assembling the battery into the corresponding equipment.

[0110] As shown in Figure 2, when the power metering module is powered on for the first time, the battery working status of the battery is obtained. When the charging module is working, it can be determined that the battery is in the charging state. When the discharging module is working, it can be determined that the battery is in the discharging state. When both the charging module and the discharging module are not working, it can be determined that the battery is in the shutdown state.

[0111] If the battery is in the off state when the power meter module is powered on for the first time, obtain the battery voltage Vbat and battery current Ibat, and calculate the battery terminal voltage Vocv as follows:

[0112] Vocv=Vbat+Ibat*Rdc

[0113] Wherein Rdc is the internal resistance of the battery, and the value of the internal resistance of the battery is pre-stored in the power metering module. Since the charging module and the discharging module are not working, Ibat is zero at this time, and Vocv is equal to Vbat.

[0114] Substitute the battery terminal voltage Vocv into the voltage-to-energy mapping curve, and use the difference algorithm to calculate the corresponding energy Pinit1 as the second energy data of the energy metering module.

[0115] When the battery is powered off, the discharge module is never turned on, so it cannot be determined whether the battery protection board is in a protected state. If the battery protection board is in an unprotected state, the second power data is accurate and can be used as the target initial power. If the battery protection board is in a protected state, the current battery voltage is only the floating charge of accumulated charge, not the actual battery voltage. The calculated second power data is inaccurate and cannot be used as the target initial power.

[0116] A second initialization is performed according to the charge and discharge state after the shutdown state is converted, and the second power data is verified to determine whether the second power data is accurate data.

[0117] When the battery is converted from the shutdown state to the discharge state, the discharge module will detect the battery voltage before turning on. The discharge module can only be turned on normally if the battery voltage is higher than the undervoltage threshold of the discharge module. The undervoltage threshold of the discharge module is generally higher than the protection voltage of the battery protection board. The discharge module is in the turned-on state, which means that the battery protection board is not in the protection state. The second power data Pinit1 obtained in the shutdown state is accurate. The second power data Pinit1 can be determined as the target initial power Pinit_final, and the initialization process ends.

[0118] When the battery is switched from the shutdown state to the charging state, it cannot be determined whether the battery protection board is in the protection state in the shutdown state. In the charging state, the battery voltage is continuously detected. When it is detected that the battery voltage exceeds the first voltage threshold for a time period exceeding the first time threshold, it can be determined that even if the battery protection board is in the protection state in the shutdown state, the battery protection board can be charged and opened after charging and is in the unprotected state. At this time, the battery voltage Vbat and the battery current Ibat are obtained, and the battery terminal voltage Vocv is calculated as follows:

[0119] Vocv=Vbat-Ibat*Rdc

[0120] Substitute the battery terminal voltage Vocv into the voltage-to-electricity mapping curve, and use the difference algorithm to calculate the corresponding electric quantity Pinit2 as the first electric quantity data of the electric quantity measurement module.

[0121] Calculate the absolute value of the difference between the first power data and the second power data Pinit_delta

[0122] Pinit_delta=|Pinit1-Pinit2|

[0123] The first difference threshold is Pinit_threshold. If Pinit_delta >= Pinit_threshold, it is considered that the battery protection board is in a protected state under the shutdown state, and the calculated second power data Pinit1 is inaccurate. Only the first power data Pinit2 is accurate. The first power data Pinit2 is used as the target initial power Pinit_final.

[0124] If Pinit_delta < Pinit_threshold, it is considered that the battery protection board is not in a protected state under the shutdown state, and the calculated second power data Pinit1 is accurate. Therefore, the second power data Pinit1 is used as the target initial power Pinit_final, and the initialization process ends.

[0125] If the battery is in a discharging state when the power measurement module is powered on for the first time, the discharging module will detect the battery voltage before it is turned on. Only when the battery voltage is higher than the undervoltage threshold of the discharging module can the discharging module be normally turned on. Generally, the undervoltage threshold of the discharging module is higher than the protection voltage of the battery protection board. The fact that the discharging module is in an open state indicates that the battery protection board is not in a protected state. Obtain the battery voltage Vbat and the battery current Ibat, and calculate the battery terminal voltage Vocv as

[0126] Vocv = Vbat + Ibat * Rdc

[0127] Substitute the battery terminal voltage Vocv into the voltage-power mapping curve, and use the difference algorithm to calculate the corresponding power Pinit3 as the third power data of the power measurement module.

[0128] Since the discharging module can be normally turned on, it indicates that the battery protection board is not in a protected state, and the third power data Pinit3 is accurate. At this time, the third power data Pinit3 can be used as the target initial power Pinit_final of the power measurement module, and the initialization process ends.

[0129] If the battery is in a charging state when the power measurement module is powered on for the first time, continuously detect the battery voltage. When the duration for which the detected battery voltage exceeds the first voltage threshold exceeds the first duration threshold, it can be determined that even if the battery protection board is in a protected state when the device is shutdown, the battery protection board can be charged and opened after charging and is in an unprotected state. Obtain the battery voltage Vbat and the battery current Ibat, and calculate the battery terminal voltage Vocv as

[0130] Vocv = Vbat + Ibat * Rdc

[0131] Substitute the battery terminal voltage Vocv into the voltage-to-energy mapping curve, and use the difference algorithm to calculate the corresponding energy Pinit2, which is used as the first energy data Pinit2 of the energy metering module. At this time, the first energy data Pinit2 can be used as the target initial energy Pinit_final of the energy metering module, and the initialization process ends. The battery power calculation method provided in the embodiment of the present application can be executed by a battery power calculation device. In the embodiment of the present application, the battery power calculation method provided in the embodiment of the present application is described by taking the battery power calculation device executing the battery power calculation method as an example.

[0135] The second processing module 420 is configured to calculate the real-time power level of the battery based on the target initial power level.

[0136] According to the battery power calculation device provided in the embodiment of the present application, by continuously detecting the battery voltage when the battery is in a charging state, when it is detected that the battery voltage of the battery exceeds the first voltage threshold for a period of time exceeding the first time threshold, it can be determined that even if the battery protection board was previously in a protection state, the battery protection board can be charged and is in an unprotected state after charging. The first power data obtained is accurate power data and can be used as the target initial power. The real-time power of the battery calculated based on the target initial power is more accurate.

[0141] Alternatively, when the absolute value of the difference is smaller than the first difference threshold, the second power data is used as the target initial power.

[0142] In some embodiments, the first processing module 410 is configured to determine the first power data as the target initial power.
