Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery management, in particular to a terminal device terminal voltage and power calibration method, system and storage medium in the technical field of battery management. BACKGROUND

[0002] In related technologies, one of the important technical routes of lithium battery power is the power display scheme based on coulomb counter and open circuit voltage (OCV) curve. The problem of coulomb counter is that there is cumulative error, and the error becomes larger due to the continuous accumulation of error in long time charging and discharging. The problem of OCV curve is that although the OCV curve is accurate in power, it is very difficult to obtain OCV in real time. The calculation of OCV by Ohm's law depends on the battery internal resistance model, and the battery internal resistance model is very complex. Therefore, the existing power estimation schemes based on coulomb counter and OCV cannot guarantee 100% accuracy of power accuracy, especially as the battery ages, the error of power accuracy increases.

DETAILED DESCRIPTION

[0010] In order to further illustrate the technical means and effects taken by the application to achieve the predetermined object of the application, the following describes in detail the specific implementation, structure, features and effects of a terminal device terminal voltage and electric quantity calibration method according to the application, combined with the preferred embodiments and the drawings. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics in one or more embodiments can be combined in any suitable form.

[0012] Hereinafter, the terms "first", "second" are only used for description purposes, and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more features.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as understood by those skilled in the art to which the application belongs.

[0014] The accuracy of battery charge display has always been a major concern for end users, especially mobile phone users. Inaccurate battery levels prevent users from accurately estimating their phone's remaining usable time, leading to unexpected battery drain and shutdown. Inaccurate battery levels can also cause the battery's shutdown voltage to drop, potentially leading to prolonged system operation in unexpectedly low-performance or unsafe voltage ranges. Inaccurate battery levels can also cause the phone to prematurely shut down after indicating 0%, impacting user usage. These issues can cause unnecessary disruption to normal phone use and may even lead users to believe there's a hardware issue with the phone, leading to complaints at best and even cancellations.

[0015] Mobile terminals are basically powered by lithium batteries, and the open circuit voltage-state of charge (OCV-SOC) curve of lithium batteries at different temperatures is one of the most accurate and reliable basic solutions for estimating the power of lithium batteries. Figure 1 As shown, three OCV curves under different parameters are Figure 1 The horizontal axis (DoD) represents the depth of discharge, and the vertical axis (Voltage) represents the voltage. Once the accurate OCV is determined during system operation, the battery level can be accurately displayed using a pre-calibrated OCV-SOC curve table at different temperatures.

[0016] Under load, the battery terminal voltage (VBAT) is greater than OCV during charging, and less than OCV during discharging. The relationship between the OCV curve and the VBAT curve in the discharge state is as follows: Figure 2 As shown, the VBAT curve exhibits a voltage drop (IR drop) due to load, and VBAT is generally less than OCV. Therefore, during discharge, the measured VBAT must be less than OCV. To do so, use VBAT as the OCV and consult an OCV table to obtain the charge level and calibrate the current charge level to ensure it is not less than the charge level represented by VBAT. Similarly, during charge, the measured VBAT must be greater than OCV. This means you can use VBAT as the OCV and consult an OCV table to obtain the charge level and calibrate the current charge level to ensure it is not greater than the charge level represented by VBAT. Terminal voltage measurement has accuracy deviations, which only need to be taken into account.

[0017] The following describes in detail a method for calibrating terminal voltage and electricity of a terminal device provided by the present invention in conjunction with the accompanying drawings. Figure 3 , which shows a schematic diagram of an implementation flow of a terminal voltage and electricity calibration method for a terminal device provided by an embodiment of the present invention, the method comprising: 301. Determine the charge and discharge status of the battery of the terminal device.

[0018] Here, the terminal device can be any type of device, such as a mobile phone, a tablet, etc. The charge-discharge state of the battery of the terminal device includes a charging state and a discharging state.

[0019] 302, based on the charge-discharge state, determine the duration that the battery is in the charge-discharge state.

[0020] Here, after determining the charge-discharge state of the battery, it is further determined whether the duration that the battery is in the charge-discharge state reaches a preset duration.

[0021] In some possible implementations, if the charge-discharge state is a discharging state, the duration that the battery is in the discharging state is determined; for example, if the battery is in a discharging state, it is further determined how long the battery has been continuously in the discharging state, i.e., the duration. If the charge-discharge state is a charging state, the duration that the battery is in the charging state is determined; for example, if the battery is in a charging state, it is further determined how long the battery has been continuously in the charging state, i.e., the duration.

[0022] 303, in the case where the duration meets the preset duration, determine the current power consumption of the battery.

[0023] Here, the preset duration is a self-defined configurable value. Taking a preset duration of 30 minutes as an example: if the charge-discharge state is a discharging state, it is determined whether the duration that the battery has been continuously in the discharging state reaches 30 minutes, and if so, it is determined that the duration meets the preset duration, and the current power consumption of the battery is further determined. In the case where the duration reaches 30 minutes, the current of the battery is determined, and the power consumption is calculated based on the current.

[0024] In some possible implementations, the above step 303 can be implemented by the steps shown in FIG. 4: Figure 4 401, if the charge-discharge state is a discharging state, determine whether the duration that the battery has been continuously in the discharging state reaches the preset duration. 402, if the duration that the battery has been continuously in the discharging state reaches the preset duration, determine the discharging current of the battery.

[0025] Here, if the charge-discharge state is a discharging state and the duration that the battery has been continuously in the discharging state reaches half an hour, the discharging current of the battery is further determined. If the charge-discharge state is a charging state and the duration that the battery has been continuously in the charging state reaches half an hour, the charging current of the battery is further determined.

[0026] 403, based on the discharging current, determine the current power consumption.

[0027] ​

[0028] Here, after the discharge current is calculated, the current power consumption under the discharge current is further calculated, so as to determine whether the small-current discharge occurs, and further to accurately calculate the current power consumption.

[0029] 304, if the current power consumption is less than the preset power consumption, a calibration voltage of the battery is determined based on the terminal voltage of the battery and the corresponding voltage accuracy.

[0030] For example, in the discharge state, it is determined whether the discharge current is less than 0.5 ampere (A), and if the discharge current is less than 0.5 A, it is determined that the current power consumption is less than the preset power consumption. Then, the terminal voltage (VBAT) of the battery and the corresponding voltage accuracy (Vthd) are obtained. The calibration voltage (Vadj) of the battery is calculated based on the terminal voltage of the battery and the corresponding voltage accuracy.

[0031] In some possible implementation manners, if the charge-discharge state is the discharge state and the current power consumption is less than the preset power consumption, a difference between the terminal voltage of the battery and the corresponding voltage accuracy is determined to determine the calibration voltage of the battery. For example, in the small-current discharge state, VBAT – Vthd is calculated to obtain the calibration voltage of the battery.

[0032] If the charge-discharge state is the charge state and the current power consumption is less than the preset power consumption, a sum of the terminal voltage of the battery and the corresponding voltage accuracy is determined to determine the calibration voltage of the battery.

[0033] For example, in the small-current charge state, VBAT + Vthd is calculated to obtain the calibration voltage of the battery. In this way, the calibration voltage of the battery can be accurately calculated based on the terminal voltage of the battery and the corresponding voltage accuracy.

[0034] 305, a voltage state of charge of the battery that matches the calibration voltage is determined.

[0035] Here, according to the calibration voltage, a table lookup operation is performed in a preset mapping table to obtain the voltage state of charge of the battery that matches the calibration voltage. The preset mapping table can represent a mapping relationship between the OCV and the SOC.

[0036] In some possible implementation manners, the step 305 can be implemented by the following steps 351 and 352 (not shown in the figure): 351, a preset mapping table representing a corresponding relationship between the remaining capacity of the battery and the open circuit voltage is obtained.

[0037] Here, the preset mapping table can be constructed by the remaining capacity of the battery and the corresponding open circuit voltage, and can represent the corresponding relationship between the remaining capacity of the battery and the open circuit voltage.

[0038] 352, determine the voltage state of charge of the battery based on the preset mapping table and the calibration voltage.

[0039] Here, after creating the preset mapping table, a lookup operation is performed in the preset mapping table according to the calibration voltage, so as to obtain the voltage state of charge of the battery.

[0040] In some possible implementation manners, the calibration voltage is determined as the open circuit voltage of the battery, and in the preset mapping table, the voltage state of charge matched with the open circuit voltage is determined.

[0041] Here, the calibration voltage Vadj is taken as the open circuit voltage OCV, and the preset mapping table is looked up, so as to obtain the voltage state of charge VSOC.

[0042] 306, determine the target battery remaining capacity of the battery based on the voltage state of charge and the charge-discharge state of the battery.

[0043] Here, the charge-discharge state of the battery is calibrated by the voltage state of charge, so as to obtain the target battery remaining capacity of the battery.

[0044] In some possible implementation manners, the above step 306 can be implemented by the following steps 361 to 363 (not shown in the figure): 361, determine the initial battery remaining capacity of the battery based on the power algorithm.

[0045] Here, the battery remaining capacity is calculated by the power algorithm, so as to obtain the initial battery remaining capacity of the battery, that is, the battery remaining capacity (RM_SOC) calculated by the power algorithm.

[0046] 362, determine the calibration mode based on the charge-discharge state of the battery.

[0047] Here, if the battery is in the charging state, the calibration mode is to determine whether the voltage state of charge is less than the initial battery remaining capacity; if the battery is in the discharging state, the calibration mode is to determine whether the voltage state of charge is greater than the initial battery remaining capacity.

[0048] 363, calibrate the initial battery remaining capacity based on the voltage state of charge by using the calibration mode, so as to obtain the target battery remaining capacity.

[0049] Here, if the battery is in the charging state, it is determined whether the voltage state of charge is less than the initial battery remaining capacity, and if the voltage state of charge is less than the initial battery remaining capacity, the voltage state of charge is assigned to the initial battery remaining capacity, so as to calibrate the initial battery remaining capacity by the voltage state of charge, and obtain the target battery remaining capacity.

[0050] If the battery is in a discharging state, it is judged whether the voltage state of charge is greater than the initial battery remaining capacity, if the voltage state of charge is greater than the initial battery remaining capacity, the voltage state of charge is assigned to the initial battery remaining capacity, the voltage state of charge is calibrated to the initial battery remaining capacity, and the target battery remaining capacity is obtained.

[0051] In some embodiments, if the current power consumption is greater than the preset power consumption, the terminal voltage of the battery is obtained; and the terminal voltage is determined as the calibration voltage of the battery. That is, if the current is in a large current scenario, the terminal voltage VBAT of the battery is taken as the calibration voltage Vadj.

[0052] In the embodiment of the application, after the charging and discharging state of the battery of the terminal device is determined, it is judged whether the duration of the battery in the charging and discharging state reaches a preset duration based on the charging and discharging state; in the case where the duration meets the preset duration, it is further determined whether the current power consumption of the battery is less than a preset power consumption; in this way, in the case where the duration is long, it is further determined whether the current power consumption of the battery is less than the preset power consumption, so that the battery remaining capacity can be calculated more accurately. If the current power consumption is less than the preset power consumption, the calibration voltage of the battery is determined based on the terminal voltage of the battery and the corresponding voltage accuracy, and the voltage state of charge of the battery matched with the calibration voltage is determined; in this way, for the case of small power consumption, the calibration voltage of the battery can be quickly calculated through the terminal voltage of the battery and the voltage accuracy, and then the target battery remaining capacity of the battery can be more accurately calculated through the voltage state of charge of the battery matched with the calibration voltage and the charging and discharging state of the battery; thereby the display accuracy of the battery power is improved.

[0053] In some embodiments, the terminal voltage power calibration method provided by the embodiment of the application can be implemented by the flow shown in the figure: Figure 5 Firstly, the charging and discharging state is judged.

[0054] Here, in the discharging scenario, it is judged whether it is in a discharging state, and the discharging calibration is only performed in the discharging state; Secondly, if it is in a discharging state, it is judged whether it is continuously discharged for 30 minutes; If it is not continuously discharged for 30 minutes, no calibration is performed.

[0055] Thirdly, if it is continuously discharged for 30 minutes, the terminal voltage VBAT is obtained.

[0056] Secondly, it is judged whether it is small power consumption discharging.

[0057] If it is not small power consumption discharging, the calibration voltage Vadj=VBAT is determined. If it is small power consumption discharging, the calibration voltage Vadj=VBAT-Vthd is determined.​

[0058] Here, it is judged whether the continuous discharge exceeds a certain time (e.g., 30 minutes), and after a certain time of stable discharge, the VBAT obtained under any discharge current is less than the OCV. The current battery terminal voltage VBAT is obtained, and it is judged whether it is a small-current discharge. The voltage impact of the small-current discharge IBAR*RBAT (i.e., the product of the battery internal resistance and the current) is very small, and can be less than the voltage precision when VBAT is collected. Therefore, in the small-current discharge scenario, the calibration voltage Vadj = VBAT-Vthd, and Vthd is the VBAT collection precision voltage.

[0059] Again, Vadj is used to query the OCV-SOC table (i.e., the preset mapping table) to obtain the capacity VSOC (i.e., the voltage state of charge of the battery).

[0060] Here, Vadj is used to query the OCV-SOC table as the OCV to obtain the capacity, so as to obtain VSOC. At this time, VSOC is certainly less than the true capacity of the battery.

[0061] Finally, the capacity calibration is realized. If the battery remaining capacity (RM_SOC) calculated by the capacity algorithm < the voltage state of charge (VSOC) of the battery, the RM_SOC is calibrated, and RM_SOC = VSOC.

[0062] In the charging scenario, first, it is judged whether it is in the charging state. Only in the charging state, the charging calibration is performed. Secondly, if it is in the charging state, it is judged whether it is continuously charged for 30 minutes. It is judged whether the continuous charging exceeds a certain time (e.g., 30 minutes), and after a certain time of stable charging, the VBAT obtained under any charging current is greater than the OCV. If the continuous charging is not 30 minutes, no calibration is performed.

[0063] Thirdly, if the continuous charging is 30 minutes, the terminal voltage VBAT is obtained.

[0064] Secondly, it is judged whether it is a small-power-consumption charging.

[0065] It is judged whether it is a small-current charging. The voltage impact of the small-current charging IBAR*RBAT is very small, and can be less than the voltage precision when VBAT is collected. Therefore, in the small-current charging scenario, the calibration voltage Vadj = VBAT + Vthd, and Vthd is the VBAT collection precision voltage. In the large-current charging scenario, Vadj = VBAT.

[0066] Thirdly, Vadj is used to query the OCV-SOC table (i.e., the preset mapping table) to obtain the capacity VSOC (i.e., the voltage state of charge of the battery).

[0067] Here, use Vadj as OCV to check the OCV-SOC table to obtain VSOC, at this time VSOC must be greater than the true capacity of the battery.

[0068] Finally, the capacity calibration is implemented, if the battery remaining capacity (RM_SOC) calculated by the capacity algorithm > voltage state of charge (VSOC) of the battery, then the RM_SOC is calibrated, RM_SOC = VSOC.

[0069] In one specific example, taking the discharge calibration as an example, the effect diagram is as shown in Figure 6 , the horizontal axis is time, the left vertical axis is the capacity percentage, the right vertical axis is the voltage V, BATT_SOC is the capacity percentage counted by the capacity meter, CALI_SOC is the capacity percentage after calibration; MSOC is the final output capacity percentage of the capacity meter; IBAT_AVG is the real-time discharge current; SMSOC is the smooth capacity reported to the upper layer; UISOC is the capacity seen by the user. Figure 6 It can be seen that after artificially introducing 20% error, continuously discharging for more than 30 minutes, the capacity starts to be calibrated (the effect of the first triggered calibration is as shown in the calibration result 61 in Figure 6 ), which can quickly calibrate the capacity to a small error range, with the current gradually decreasing, triggering the second calibration (the calibration result of the second triggered calibration is as shown in the calibration result 62 in Figure 6 ), which calibrates the capacity to a very accurate value.
