Description

Technical Field

[0001] This application belongs to the field of smart charging technology, specifically relating to a battery power calibration method, device, electronic device, and storage medium. Background Technology

[0002] Accurate estimation of the remaining battery charge (SOC) is the core foundation for energy management and range prediction in electric vehicles, directly impacting user experience and driving safety. Precise SOC is crucial for ensuring the reliability of vehicle range display and for the battery management system (BMS) to assess and manage battery charge.

[0003] Currently, the industry generally adopts a battery calibration method based on full charge calibration to reset the remaining battery level displayed in the range indicator or correct the error between the remaining battery level and the actual battery condition. However, since the vehicle only meets the condition to trigger full charge calibration when the charging limit is set to 100%, if users want accurate battery level display in the range indicator, they need to fix the charging limit to the full charge calibration limit. Frequent full charging will put lithium-ion batteries under high pressure stress for a long time, which will accelerate the structural decay of the positive electrode material and electrolyte decomposition, and accelerate the thickening of the SEI film and lithium deposition on the negative electrode surface, thus significantly shortening the battery life. If users want to protect the battery life, they need to fix the charging limit to, for example, 8. The battery is charged within a range of 0% to 90% to avoid entering the high-voltage zone. However, this directly prevents the battery management system from having a full charge calibration opportunity for a long time. The SOC estimation error continues to accumulate and cannot be effectively calibrated, putting users in a dilemma: if they choose not to fully charge to protect the battery, they have to bear the risk of inaccurate battery level display; if they fully charge for a long time to obtain accurate battery level, they will sacrifice the long-term battery life. Thus, the current contradiction of long-term full charging leading to battery life damage and not fully charging leading to inaccurate battery level display cannot balance the user's need for battery life and accurate range display, affecting the user's driving experience. Summary of the Invention

[0004] The purpose of this application is to provide a battery power calibration method, device, electronic device, and storage medium, which can solve the current contradiction that long-term full charging leads to battery life damage, while partial charging results in inaccurate display of remaining battery power. This fails to balance the user's pursuit of battery life and range display accuracy, thus affecting the user's driving experience.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: In a first aspect, embodiments of this application provide a battery power calibration method, the method comprising: When the vehicle is charging, obtain the user's currently set charging limit; If the charging limit is lower than the battery's full charge threshold, then the vehicle is judged one by one in a preset order to determine whether it meets the preset calibration trigger conditions; wherein the preset calibration trigger conditions are set based on at least one of the following factors: ambient temperature, driving style, driving mileage, idle time and vehicle usage cycle. If the vehicle meets any of the calibration trigger conditions, a prompt message to perform full charge calibration will be sent to the user; In response to receiving confirmation from the user regarding the prompt information, the system controls the vehicle to perform a full charge calibration.

[0006] Based on the aforementioned technical means, when the vehicle is charging, it is determined whether the user's currently set charging limit meets the conditions for full charge calibration. Therefore, even when the user selects a non-full charge charging limit, the system comprehensively considers multiple factors affecting the accuracy of the range display and efficiently and orderly triggers the full charge calibration. This reasonable and automatic triggering of full charge calibration effectively reduces battery life damage caused by prolonged full charging. Appropriate full charge calibration effectively corrects deviations in battery power estimation and improves the accuracy of the range display. This avoids the contradiction between prolonged full charging causing battery life damage and inaccurate battery power display due to insufficient charging. It balances the user's needs for extending battery life and ensuring range display accuracy, achieving intelligent battery power calibration and further enhancing the user experience.

[0007] Optionally, if the charging limit is lower than the battery's full charge threshold, then the vehicle is checked one by one in a preset order to determine whether it meets the preset calibration trigger conditions, including: If the charging limit is lower than the battery's full charge threshold, a preset order for determining the calibration trigger conditions is determined; wherein, the preset order is, in order, ambient temperature, driving style, mileage, resting time, and vehicle usage cycle. According to the preset sequence, the system acquires the vehicle's ambient temperature, driving style, mileage, resting time, and usage cycle, and then determines whether the vehicle meets the preset calibration trigger conditions.

[0008] Based on the above technical means, and the judgment order of calibration trigger conditions, the judgment of full charge calibration is carried out efficiently and orderly, and the SOC estimation deviation is detected and calibrated in a timely manner. It can make intelligent judgments based on the user's actual usage, reducing the inconvenience of manual operation for the user, thereby achieving accurate full charge calibration.

[0009] Optionally, the step of acquiring the vehicle's ambient temperature, driving style, mileage, resting time, and usage cycle in a preset order, and determining whether the vehicle meets the preset calibration trigger conditions one by one, includes: Determine whether the vehicle's ambient temperature meets the first calibration trigger condition. If so, the vehicle meets the calibration trigger condition and the determination ends. If not, determine whether the user's driving style meets the second calibration trigger condition; if so, the vehicle meets the calibration trigger condition and the judgment ends. If not, determine whether the vehicle's mileage meets the third calibration trigger condition. If yes, the vehicle meets the calibration trigger condition and the judgment ends. If not, determine whether the vehicle's stationary time meets the fourth calibration trigger condition. If yes, the vehicle meets the calibration trigger condition and the judgment ends. If not, determine whether the vehicle's usage cycle meets the fifth calibration trigger condition. If yes, the vehicle meets the calibration trigger condition and the judgment ends; otherwise, the vehicle does not meet the calibration trigger condition.

[0010] Based on the aforementioned technical means, and according to the judgment order of calibration trigger conditions, the judgment of full charge calibration is carried out efficiently and orderly, so as to reasonably and effectively trigger full charge calibration, ensure that the battery power is calibrated in a timely and effective manner, and meet the user's needs for the accuracy of battery life display.

[0011] Optionally, the method further includes: If the cumulative duration of the vehicle's ambient temperature being within the preset temperature range exceeds the first threshold, then the vehicle's ambient temperature meets the first calibration trigger condition. If the number of times the user performs emergency acceleration and deceleration within the preset driving mileage exceeds the second threshold, or the vehicle's average energy consumption is greater than the third threshold, then the user's driving style meets the second calibration trigger condition. If the vehicle's mileage exceeds the fourth threshold within a preset period, then the vehicle's mileage meets the third calibration trigger condition. If the vehicle's stationary time exceeds the fifth threshold within the preset period, then the vehicle's stationary time satisfies the fourth calibration trigger condition. If the vehicle's usage period exceeds the sixth threshold, then the vehicle's usage period meets the fifth calibration trigger condition.

[0012] Based on the above technical means, by calibrating and triggering judgments of multi-dimensional influencing factors, full charge calibration is triggered appropriately and reasonably, which effectively alleviates the contradiction that long-term full charging will damage battery life, while incomplete charging will result in inaccurate display of remaining battery power. This balances the user's needs to extend battery life and ensure the accuracy of battery life display.

[0013] Optionally, if the vehicle meets any of the calibration trigger conditions, a prompt message to the user to perform a full charge calibration is sent, including: If the vehicle meets any of the aforementioned calibration trigger conditions, the judgment ends and a prompt message to the user to perform full charge calibration is sent; wherein, the prompt message is displayed locally on the vehicle's infotainment system or on a remote terminal, and is used by the user to confirm whether to perform full charge calibration.

[0014] Based on the aforementioned technical means, the system intelligently determines whether to trigger full charge calibration based on multiple triggering conditions, and interacts with the user through user-friendly prompts. After user confirmation, full charge calibration is performed, effectively correcting the deviation in battery status estimation and ensuring the accuracy of battery power when the user uses the vehicle next time.

[0015] Optionally, the step of controlling the vehicle to perform a full-charge calibration in response to receiving confirmation from the user regarding the prompt information includes: In response to receiving confirmation from the user regarding the prompt information, the charging limit for this charge is adjusted from the user-set charging limit to the full charge calibration threshold. The battery is controlled to charge according to the full charge calibration strategy until the battery level meets the full charge threshold, and the charging limit for this charge is restored to the charging limit set by the user.

[0016] Based on the above technical means, full charge calibration is automatically performed according to the user's confirmed operation. Full charge calibration is triggered appropriately when the conditions are met, which effectively corrects the deviation of battery power estimation. After the full charge calibration is completed, the user settings are automatically restored, realizing intelligent management of battery charging.

[0017] Optionally, the method further includes: If the vehicle does not meet any of the calibration trigger conditions, the timing or count associated with the calibration trigger condition determination will be reset, and the battery will be charged according to the charging limit currently set by the user.

[0018] Based on the aforementioned technical means, charging is performed according to the user-set charging limits to ensure that the user can charge according to their needs, avoiding interference from frequent full-charge calibration. By resetting the timer or counter, the calibration trigger condition is accurately determined during the next charge, thus improving the user experience.

[0019] Secondly, embodiments of this application provide a battery power calibration device, the device comprising: The charging limit acquisition module is used to acquire the charging limit currently set by the user when the vehicle is in a charging state. The condition judgment module is used to determine whether the vehicle meets the preset calibration trigger conditions one by one in a preset order if the charging limit is lower than the full charge threshold of the battery; wherein the preset calibration trigger conditions are set based on at least one of the following factors: ambient temperature, driving style, driving mileage, rest time and vehicle usage cycle. The calibration prompt module is used to send a prompt message to the user to perform full charge calibration if the vehicle meets any of the calibration trigger conditions. The control calibration module is used to control the vehicle to perform full charge calibration in response to receiving confirmation from the user regarding the prompt information.

[0020] Thirdly, embodiments of this application provide an electronic device including a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the battery power calibration method as described in the first aspect.

[0021] Fourthly, embodiments of this application provide a readable storage medium storing a program or instructions that, when executed by a processor, implement the steps of the battery power calibration method as described in the first aspect.

[0022] The battery power calibration method provided in this application obtains the user's currently set charging limit when the vehicle is in a charging state. If the charging limit is lower than the battery's full charge threshold, the method determines whether the vehicle meets preset calibration trigger conditions one by one in a preset order. The preset calibration trigger conditions are set based on at least one of the following factors: ambient temperature, driving style, mileage, idle time, and vehicle usage cycle. If the vehicle meets any calibration trigger condition, a prompt message to perform full charge calibration is sent to the user. In response to receiving the user's confirmation of the prompt message, the method controls the vehicle to perform full charge calibration. This embodiment of the application, when the vehicle is in a charging state, determines whether the user's currently set charging limit meets the conditions for full charge calibration. Therefore, even when the user selects a non-full charge charging limit, it efficiently and systematically triggers full charge calibration by considering multiple factors affecting the accuracy of the range display. This reasonable and automatic triggering of full charge calibration effectively reduces battery life damage caused by prolonged full charging. Appropriate full charge calibration effectively corrects deviations in battery power estimation, improving the accuracy of the range display. This avoids the contradiction between prolonged full charging causing battery life damage and inaccurate battery power display due to insufficient charging. It balances the user's needs for extending battery life and ensuring accurate range display, achieving intelligent battery power calibration and further enhancing the user experience.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The battery power calibration method, apparatus, electronic device, and storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0028] Example 1 Reference Figure 1 The diagram illustrates a flowchart of a battery power calibration method provided in an embodiment of this application. The method may include: Step 110: While the vehicle is charging, obtain the charging limit currently set by the user.

[0029] In this embodiment, to address the contradiction between prolonged full charging leading to battery lifespan damage and inaccurate battery remaining charge display due to partial charging, thus failing to balance users' demands for battery lifespan and accurate range display, the battery management system first obtains the user's currently set charging limit when the vehicle is charging. This determines whether the user's current charging limit meets the conditions for full charge calibration. If the user selects a non-full charge charging limit, the system automatically triggers full charge calibration by considering multiple factors that reduce the accuracy of range display for lithium batteries, especially lithium iron phosphate batteries. This timely and effective full charge calibration balances the user's demands for battery lifespan and accurate range display.

[0030] It should be noted that in this embodiment, "vehicle in charging state" refers to the vehicle's charging port being connected to a charging station or other charging equipment, ready to start charging. This ensures that the full charge calibration process is triggered safely and effectively while the vehicle is charging. The charging limit is a maximum charging capacity that the user can set when charging the vehicle, usually expressed as a percentage such as 80% or 90%. The charging limit determines when charging will stop once the user-set percentage is reached. When the vehicle is ready to charge, the battery management system automatically obtains the user-set charging limit to determine whether full charge calibration is necessary.

[0031] Reference Figure 2 This illustration shows a schematic diagram of the architecture of a battery charge calibration method provided in this application embodiment. This embodiment takes the battery management system as the execution subject as an example for description. The battery management system is communicatively connected to the vehicle control unit (VCU). The battery management system can obtain the vehicle data required for full charge calibration from the vehicle control unit. The vehicle control unit is communicatively connected to the brake control system (BCS), drive motor control unit (DCU), and central control unit (CCU). The brake control system is used to collect the vehicle's braking data from the brake pedal, and the drive motor control unit is used to collect the vehicle's throttle data from the accelerator pedal. The central control unit is communicatively connected to the T-box controller and the infotainment domain controller. The T-box controller is used to provide timing and remote control services for the vehicle, and the infotainment domain controller is used to control the vehicle screen, such as the central control display screen, and interact with the user. In addition, the central control unit can also be connected to the collision G-value sensor and the outside temperature sensor to obtain the acceleration and deceleration g-value collected by the collision G-value sensor and the ambient temperature collected by the parking space temperature sensor. This embodiment will not elaborate on these aspects.

[0032] Step 120: If the charging limit is lower than the battery's full charge threshold, then determine whether the vehicle meets the preset calibration trigger conditions one by one in a preset order; wherein, the preset calibration trigger conditions are set based on at least one of the following factors: ambient temperature, driving style, mileage, rest time, and vehicle usage cycle.

[0033] In this embodiment, if the charging limit is lower than the battery's full charge threshold, a full charge calibration judgment is performed. This proactively confirms with the user and performs full charge calibration when the calibration trigger conditions are met. In this embodiment, the vehicle's compliance with the preset calibration trigger conditions is determined sequentially according to a preset order, i.e., according to a certain priority order. The preset calibration trigger conditions are set based on at least one of the following factors: ambient temperature, driving style, mileage, idle time, and usage cycle. The preset order is a priority order determined based on the battery characteristics and charging status of a large number of vehicles. The preset order can be obtained by ranking the influence of the main factors causing a decrease in the accuracy of the range display for lithium batteries, especially lithium iron phosphate batteries. This embodiment does not limit the process for determining the influence of each factor.

[0034] It should be noted that, to ensure the effectiveness of the full-charge calibration trigger, based on the battery characteristics of different vehicle models, the main influencing factors causing reduced range display accuracy for lithium batteries, especially lithium iron phosphate batteries, were comprehensively determined. These factors include ambient temperature, driving style, mileage, resting time, and usage cycle. Ambient temperature refers to the external ambient temperature of the vehicle, usually monitored in real-time by the vehicle's external temperature sensor. Ambient temperature has a significant impact on battery performance and the estimation of remaining battery capacity. Low or high temperatures may cause changes in the battery's chemical reaction rate, thus affecting the actual usable capacity and the accuracy of remaining battery capacity estimation. Driving style refers to the user's... Driving behavior characteristics exhibited during driving, including rapid acceleration, rapid deceleration, continuous high-speed driving, and average energy consumption, can lead to changes in the battery's discharge rate and energy consumption pattern. Mileage refers to the cumulative distance a vehicle travels within a certain period; prolonged driving can cause deviations in battery SOC estimation. Idle time refers to the cumulative time a vehicle remains undriven or uncharged within a certain period; prolonged idle time can lead to battery self-discharge, thus affecting the accuracy of SOC estimation. Usage cycle refers to the time interval between the last full-charge calibration and the current state; a long usage cycle can lead to accumulated deviations in battery SOC estimation.

[0035] In this embodiment, the above-mentioned influencing factors are evaluated for their impact, and prioritized according to their influence from largest to smallest. Correspondingly, the preset calibration trigger conditions are set based on at least one of the following factors: ambient temperature, driving style, mileage, rest time, and vehicle usage cycle. Thus, the vehicle is judged one by one according to the preset order to determine whether it meets the preset calibration trigger conditions. The judgment is performed in order of the influence of the factors, which can clearly determine the logic, and the code is concise and efficient. The battery management system does not need to process the monitoring data of all influencing factors at the same time. It only needs to judge the calibration trigger conditions one by one in sequence to obtain the judgment result of full charge calibration in a timely and effective manner, reducing the amount of data processing and reducing hardware configuration costs.

[0036] Step 130: If the vehicle meets any calibration trigger condition, a prompt message to perform full charge calibration is sent to the user.

[0037] In this embodiment, if the vehicle meets any calibration trigger condition of ambient temperature, driving style, mileage, rest time, or usage cycle, the battery management system will send a prompt message to the user to perform full charge calibration. The prompt message can be displayed locally on the vehicle or on a remote terminal so that the user can confirm in a timely and effective manner whether to perform full charge calibration.

[0038] Step 140: In response to receiving confirmation from the user regarding the prompt message, control the vehicle to perform a full charge calibration.

[0039] In this embodiment, after the user confirms the prompt message, the battery management system responds by controlling the vehicle to perform a full-charge calibration upon receiving the confirmation. Specifically, the charging limit for this charge can be adjusted from the user-set limit (e.g., 80% or 90%) to the full-charge calibration threshold of 100%. The battery is then controlled to charge according to the full-charge calibration strategy until the battery capacity reaches the full-charge threshold. After the full-charge calibration is completed, the charging limit for this charge is restored to the user-set limit.

[0040] This embodiment of the application, when the vehicle is in a charging state, determines whether the user's currently set charging limit meets the conditions for full charge calibration. Therefore, even when the user selects a non-full charge charging limit, it efficiently and systematically triggers full charge calibration by considering multiple factors affecting the accuracy of the range display. This reasonable and automatic triggering of full charge calibration effectively reduces battery life damage caused by prolonged full charging. Appropriate full charge calibration effectively corrects deviations in battery power estimation, improving the accuracy of the range display. This avoids the contradiction between prolonged full charging causing battery life damage and inaccurate battery power display due to insufficient charging. It balances the user's needs for extending battery life and ensuring accurate range display, achieving intelligent battery power calibration and further enhancing the user experience.

[0041] Example 2 In some embodiments of this application, if the charging limit is lower than the full charge threshold of the battery in step 120, then the vehicle is judged one by one according to a preset order to determine whether the vehicle meets the preset calibration trigger conditions. Specifically, the following steps may be included: S11, if the charging limit is lower than the full charge threshold of the battery, determine the preset order of judging the calibration trigger conditions; wherein, the preset order is ambient temperature, driving style, driving mileage, rest time and vehicle usage cycle. S12, in a preset order, acquires the vehicle's ambient temperature, driving style, mileage, resting time and usage cycle, and determines whether the vehicle meets the preset calibration trigger conditions one by one.

[0042] In the above steps of this application embodiment, if the charging limit is lower than the battery's full charge threshold, a preset order for judging calibration trigger conditions is determined. The preset order is, in order, ambient temperature, driving style, mileage, resting time, and usage cycle. The charging limit is a user-set charging upper limit, such as 80% or 90%, while the full charge threshold is typically 100%. If the user-set charging limit is lower than 100%, the battery management system will enter the calibration trigger condition judgment process, judging the calibration trigger conditions one by one according to the preset order. The preset order is, in order, ambient temperature, driving style, mileage, resting time, and usage cycle. Since ambient temperature has the most direct and significant impact on battery performance, it is set as the primary judgment condition. If the ambient temperature does not meet the calibration trigger condition, the battery management system will continue to judge other influencing factors.

[0043] In this embodiment, the battery management system can efficiently determine whether a full charge calibration is needed by using a preset sequence, avoiding the waste of resources caused by disordered judgment. Ambient temperature is used as the primary judgment condition to ensure that calibration can be performed first in extreme temperature environments, thereby avoiding SOC estimation deviation caused by temperature affecting battery performance. The preset sequence can be adjusted according to actual needs to adapt to different vehicle or user usage scenarios, which will not be elaborated here.

[0044] In this embodiment, the system acquires the vehicle's ambient temperature, driving style, mileage, resting time, and usage cycle in a preset order, and then determines whether the vehicle meets the preset calibration trigger conditions one by one. The system will acquire the relevant data of ambient temperature, driving style, mileage, resting time, and usage cycle corresponding to the current calibration trigger condition in a preset order after determining the current calibration trigger condition, thereby determining whether the vehicle meets the preset calibration trigger conditions one by one. In specific implementation, if a calibration trigger condition currently being judged is met, full charge calibration is triggered; if all calibration trigger conditions have been judged and none are met, the judgment process ends.

[0045] Based on the judgment order of calibration trigger conditions, the embodiments of this application efficiently and orderly perform the judgment of full charge calibration, promptly detect and calibrate the SOC estimation deviation, and can make intelligent judgments according to the user's actual usage, reducing the inconvenience of manual operation for the user, thereby achieving accurate full charge calibration.

[0046] In some embodiments of this application, S12 involves acquiring the vehicle's ambient temperature, driving style, mileage, resting time, and usage cycle in a preset order, and determining whether the vehicle meets the preset calibration trigger conditions one by one. Specifically, this may include the following steps: Sub-step 01: Determine whether the ambient temperature of the vehicle meets the first calibration trigger condition. If so, the vehicle meets the calibration trigger condition and the determination ends. Sub-step 02: If not, determine whether the user's driving style meets the second calibration trigger condition; if yes, the vehicle meets the calibration trigger condition and the judgment ends. Sub-step 03: If not, determine whether the vehicle's mileage meets the third calibration trigger condition; if yes, the vehicle meets the calibration trigger condition and the judgment ends. Sub-step 04: If not, determine whether the vehicle's stationary time meets the fourth calibration trigger condition; if yes, the vehicle meets the calibration trigger condition and the judgment ends. Sub-step 05: If not, determine whether the vehicle's usage cycle meets the fifth calibration trigger condition. If yes, the vehicle meets the calibration trigger condition and the judgment ends; otherwise, the vehicle does not meet the calibration trigger condition.

[0047] In the above steps of this application embodiment, since ambient temperature has the most significant impact on battery performance, it is the primary factor in determining the calibration trigger condition. The first calibration trigger condition is used to determine whether the ambient temperature of the vehicle meets the requirements for full-charge calibration. If the ambient temperature of the vehicle meets the first calibration trigger condition, full-charge calibration can be directly triggered. If the ambient temperature of the vehicle does not meet the first calibration trigger condition, the next calibration trigger condition is determined according to a preset order. By using ambient temperature as the primary determination condition, full-charge calibration is prioritized in extreme temperature environments, avoiding the impact of temperature on battery performance.

[0048] In this embodiment, if not, the system continues to determine the next calibration trigger condition according to a preset sequence. This involves determining whether the user's driving style meets the second calibration trigger condition. Driving style is the second determining factor, including rapid acceleration, rapid deceleration, high-speed driving, and average energy consumption. The second calibration trigger condition is used to determine whether the user's driving behavior meets the requirements for full-charge calibration. If the user's driving style meets the second calibration trigger condition, the vehicle meets the calibration trigger condition and the determination ends. If the user's driving style does not meet the second calibration trigger condition, the system continues to determine the next calibration trigger condition. This determination based on the user's driving behavior ensures personalized full-charge calibration and prevents "phantom battery" or "battery trip" issues during the user's next vehicle use.

[0049] In this embodiment, if not, the system continues to determine the next calibration trigger condition according to a preset sequence. This involves checking whether the vehicle's mileage meets the third calibration trigger condition. Mileage is the third determining factor, reflecting the vehicle's usage frequency and battery discharge depth. The third calibration trigger condition is used to determine whether the vehicle's mileage meets the requirements for full-charge calibration. If the vehicle's mileage meets the third calibration trigger condition, the vehicle meets the calibration trigger condition and the determination ends. If the vehicle's mileage does not meet the third calibration trigger condition, the system continues to determine the next calibration trigger condition. Based on actual usage, for vehicles used frequently, timely calibration can be performed, avoiding the accumulation of SOC estimation deviations.

[0050] In this embodiment, if not, the system continues to determine the next calibration trigger condition according to a preset sequence. This involves determining whether the vehicle's resting time meets the fourth calibration trigger condition. Resting time is the fourth determining factor, reflecting the vehicle's usage frequency and battery self-discharge. The fourth calibration trigger condition is used to determine whether the vehicle's resting time meets the requirements for full-charge calibration. If the vehicle's resting time meets the fourth calibration trigger condition, the vehicle meets the calibration trigger condition and the determination ends. If the vehicle's resting time meets the fourth calibration trigger condition, the system continues to determine the next calibration trigger condition. By determining the resting time, the system adapts to different users' habits. For vehicles that have not been used for a long time, timely calibration can be performed, avoiding SOC estimation deviations caused by battery self-discharge.

[0051] In this embodiment, if not, the next calibration trigger condition is determined according to a preset order. This involves determining whether the vehicle's usage cycle meets the fifth calibration trigger condition. If yes, the vehicle meets the calibration trigger condition and the determination ends; otherwise, the vehicle does not meet the calibration trigger condition. The usage cycle is the fifth determining factor, reflecting the vehicle's usage frequency and the cumulative SOC estimation deviation. The fifth calibration trigger condition is used to determine whether the vehicle's usage cycle meets the requirements for full-charge calibration. If the usage cycle does not meet the fifth calibration trigger condition, the vehicle is determined not to meet the calibration trigger condition. All influencing factors and calibration trigger conditions have been determined, and the requirements for full-charge calibration have not been met. Full-charge calibration will not be performed during this charge, and the determination will be repeated during the next charge.

[0052] This application embodiment is based on the judgment order of calibration trigger conditions to efficiently and orderly judge full charge calibration, so as to reasonably and effectively trigger full charge calibration, ensure that the battery power is calibrated in a timely and effective manner, and meet the user's needs for the accuracy of battery life display.

[0053] In some embodiments of this application, the method further includes: Step 01: If the cumulative duration of the vehicle's ambient temperature being within the preset temperature range exceeds the first threshold, then the vehicle's ambient temperature meets the first calibration trigger condition. Step 02: If the number of times the user performs emergency acceleration and deceleration within the preset driving mileage exceeds the second threshold, or the average energy consumption of the vehicle is greater than the third threshold, then the user's driving style meets the second calibration trigger condition. Step 03: If the vehicle's mileage exceeds the fourth threshold within the preset period, then the vehicle's mileage meets the third calibration trigger condition. Step 04: If the vehicle's stationary time exceeds the fifth threshold within the preset period, then the vehicle's stationary time satisfies the fourth calibration trigger condition. Step 05: If the vehicle's usage period exceeds the sixth threshold, then the vehicle's usage period meets the fifth calibration trigger condition.

[0054] As a specific implementation of this application embodiment, in the above steps, based on the acquired ambient temperature, driving style, mileage, resting time, and usage cycle of the vehicle, it is determined whether the vehicle meets the preset calibration trigger conditions one by one, according to a preset order. Each influencing factor corresponds to a calibration trigger condition. Through multi-dimensional calibration trigger judgment, full charge calibration is appropriately and reasonably triggered when needed, so as to effectively alleviate the contradiction that long-term full charging will damage the battery life, while incomplete charging will result in inaccurate display of the remaining battery power.

[0055] In practice, the preset temperature range is obtained by dividing the ambient temperature into three intervals. For example, an ambient temperature below 5°C is considered a low-temperature environment, an ambient temperature above 5°C but below 35°C is considered a normal-temperature environment, and an ambient temperature above 35°C is considered a high-temperature environment. If the cumulative duration of the vehicle's ambient temperature within the preset temperature range exceeds a first threshold, then the vehicle's ambient temperature meets the first calibration trigger condition. For example, if the cumulative duration of the vehicle being stationary in a low-temperature environment exceeds the first threshold (e.g., 8 hours) or the cumulative duration of driving / stationary operation in a high-temperature environment exceeds the first threshold (e.g., 72 hours), then the ambient temperature meets the first calibration trigger condition. Under extreme temperature conditions, battery performance and the estimation of remaining battery capacity may be affected. By performing full-charge calibration in a timely manner under extreme temperature conditions, the accuracy of the battery status is ensured, avoiding "phantom battery" and "battery trip" situations for users during the next vehicle use.

[0056] In this embodiment, driving style factors include rapid acceleration / deceleration, continuous high-speed driving, and average energy consumption. If the number of times the user performs emergency acceleration / deceleration within a preset driving mileage exceeds a second threshold, or the vehicle's average energy consumption exceeds a third threshold, then the user's driving style meets the second calibration trigger condition. For example, within a preset driving mileage, such as a cumulative driving of 200km, if the user performs rapid acceleration more than or equal to the second threshold (e.g., 15 times), or rapidly decelerates more than or equal to the second threshold (e.g., 20 times), or the average energy consumption exceeds the third threshold (e.g., more than 25% of the vehicle's rated energy consumption), then the driving style meets the second calibration trigger condition. Aggressive driving styles can lead to inaccurate battery SOC estimation. By performing full-charge calibration under specific driving behaviors, the accuracy of SOC estimation can be restored, ensuring the reliability of the battery state when the user uses the vehicle again.

[0057] In this embodiment, if the vehicle's mileage exceeds the fourth threshold within a preset period, the vehicle's mileage meets the third calibration trigger condition. For example, if the vehicle's cumulative mileage exceeds the fourth threshold (e.g., 2000 km) within 30 days, the mileage meets the third calibration trigger condition. Prolonged and high-mileage driving may lead to battery aging or SOC estimation errors. Performing full-charge calibration when the mileage exceeds the threshold ensures the accuracy of the battery status and prevents "phantom battery" and "sudden battery drain" issues during the next vehicle use. In this embodiment, if the vehicle's idle time exceeds the fifth threshold within a preset period, the idle time meets the fourth calibration trigger condition. For example, if the vehicle's continuous idle time exceeds the fifth threshold (e.g., 15 days) within 30 days, the idle time meets the fourth calibration trigger condition. Prolonged idle time may lead to battery self-discharge or SOC estimation errors. By performing full-charge calibration promptly after the idle time exceeds the threshold, the accuracy of the battery status can be restored, ensuring the reliability of the battery status during the next vehicle use. It should be noted that this embodiment does not specifically limit the preset period, which can be set according to user needs or vehicle usage. This embodiment uses 30 days as an example for explanation.

[0058] In this embodiment, if the vehicle's usage period exceeds the sixth threshold, the usage period meets the fifth calibration trigger condition. The usage period represents the time interval from the last full-charge calibration to the present. A long usage period may lead to the accumulation of battery SOC estimation deviations. For example, if the user does not perform a full-charge calibration within 35 days, i.e., the usage period is greater than the sixth threshold, such as 30 days, then the usage period meets the fifth calibration trigger condition. The lack of a full-charge calibration for a long time may lead to accumulated errors in battery state. A benchmark calibration period ensures that full-charge calibration is performed on time.

[0059] This application embodiment uses calibration trigger judgment based on multi-dimensional influencing factors to appropriately and reasonably trigger full charge calibration, effectively alleviating the contradiction that long-term full charging will damage battery life, while incomplete charging will result in inaccurate display of remaining battery power. This balances the user's needs to extend battery life and ensure the accuracy of battery life display.

[0060] Example 3 In some embodiments of this application, step 130, if the vehicle meets any of the calibration trigger conditions, sends a prompt message to the user to perform a full charge calibration, which may specifically include: If the vehicle meets any of the aforementioned calibration trigger conditions, the judgment ends and a prompt message to the user to perform full charge calibration is sent; wherein, the prompt message is displayed locally on the vehicle's infotainment system or on a remote terminal, and is used by the user to confirm whether to perform full charge calibration.

[0061] In the steps described above in this application embodiment, when the vehicle meets any calibration trigger condition of ambient temperature, driving style, mileage, rest time, or usage cycle, the battery management system will end the judgment and send a prompt message to the user to perform full charge calibration. This prompt message can be displayed locally on the vehicle's infotainment system (e.g., the central control screen) or remotely via a T-box, mobile app, or cloud platform, allowing the user to promptly and effectively confirm whether to perform full charge calibration. The prompt message typically includes the reason for full charge calibration and operation options such as "Confirm Execution" or "Cancel." Users can choose whether to perform full charge calibration according to their needs, enhancing their right to know and their right to choose, eliminating the need for frequent manual adjustments to charging limits.

[0062] In this embodiment, by continuously and multidimensionally judging the calibration trigger conditions, when the vehicle meets any calibration trigger condition, a prompt message to perform full charge calibration is actively sent to the user. The user can clearly understand the reason and necessity of full charge calibration and choose whether to perform calibration according to their own needs. This effectively alleviates the contradiction between long-term full charging causing damage to battery life and inaccurate display of remaining battery power when not fully charged, thus balancing the user's needs for pursuing battery life and range display accuracy.

[0063] This application embodiment intelligently determines whether to trigger full charge calibration based on multiple triggering conditions, and interacts with the user through user-friendly prompts. After user confirmation, full charge calibration is performed, effectively correcting the deviation in battery state estimation and ensuring the accuracy of battery power when the user uses the vehicle next time.

[0064] In some embodiments of this application, step 140, in response to receiving confirmation from the user regarding the prompt information, controls the vehicle to perform a full-charge calibration, may specifically include: In response to receiving confirmation from the user regarding the prompt information, the charging limit for this charge is adjusted from the user-set charging limit to the full charge calibration threshold. The battery is controlled to charge according to the full charge calibration strategy until the battery level meets the full charge threshold, and the charging limit for this charge is restored to the charging limit set by the user.

[0065] In the above steps of this application embodiment, after the user confirms the prompt information, the battery management system will control the vehicle to perform full charge calibration. Specifically, the charging limit for this charge will be adjusted from the user-set charging limit, such as 80% or 90%, to the full charge threshold of 100% for full charge calibration. The battery will be controlled to charge according to the full charge calibration strategy until the battery capacity reaches the full charge threshold. After the full charge calibration is completed, the charging limit for this charge will be restored to the charging limit originally set by the user.

[0066] In this embodiment, after receiving the full charge calibration prompt message on the vehicle's central control display screen or remote terminal, the user confirms whether the vehicle should perform full charge calibration for this charge. The battery management system receives the user's confirmation and begins to execute the full charge calibration process. The full charge calibration strategy may include controlling the charging equipment to charge according to a preset full charge calibration charging curve. The charging curve includes at least a constant current charging stage and a constant voltage charging stage. When the battery terminal voltage reaches the full charge voltage threshold and the charging current drops to the preset cutoff current and is maintained for a preset duration, the full charge calibration is determined to be complete. This embodiment does not limit the specific process of full charge calibration.

[0067] In this embodiment, when the vehicle battery starts charging, the battery management system monitors the battery status in real time until the battery level reaches 100%. Once the battery level reaches 100%, the full charge calibration is completed, and the charging limit for this charge is restored from 100% to the user's original setting, such as 80%, to ensure that the user charges according to the set limit on the next charge. By automatically adjusting the charging limit to 100%, the accuracy of the full charge calibration is achieved, correcting the deviation in battery status estimation. After the full charge calibration is completed, the user-set charging limit is automatically restored to ensure that the user charges according to the set limit on the next charge. The user only needs to confirm the execution of the full charge calibration, and the charging limit adjustment, full charge calibration, and limit restoration are automatically completed, simplifying the user operation.

[0068] This application embodiment automatically performs full charge calibration based on user confirmation, appropriately triggers full charge calibration when conditions are met, effectively corrects deviations in battery power estimation, and automatically restores user settings after full charge calibration is completed, thus realizing intelligent management of battery charging.

[0069] In some embodiments of this application, the method further includes: If the vehicle does not meet any of the calibration trigger conditions, the timing or count associated with the calibration trigger condition determination will be reset, and the battery will be charged according to the charging limit currently set by the user.

[0070] In the above steps of this application embodiment, if the vehicle does not meet any calibration trigger condition such as ambient temperature, driving style, mileage, idle time, or usage cycle, the timer or counter associated with the calibration trigger condition judgment will be reset, and the battery will be charged according to the user's currently set charging limit. Specifically, the timer or counter associated with the calibration trigger condition judgment will be reset, such as the cumulative duration of ambient temperature, the number of rapid acceleration / deceleration times, high-speed driving time, average energy consumption, cumulative mileage, idle time, etc. The battery will be charged according to the user's currently set charging limit, such as 80% or 90%, and full charge calibration will not be performed.

[0071] This application embodiment charges according to the user-set charging limit, ensuring that the user can charge according to their needs, avoiding the interference of frequent full-charge calibration on the user's charging needs, and by resetting the timer or counter, it ensures that the calibration trigger condition is accurately determined during the next charge, thus improving the user experience.

[0072] Example 4 Reference Figure 3 The diagram illustrates a flowchart of a battery power calibration method provided in an embodiment of this application. In its specific implementation: S1, determine the charging limit set by the user; S2, determine whether the ambient temperature meets the calibration trigger condition; S3, determines whether the driving style meets the calibration trigger conditions; S4, determine whether the driving mileage meets the calibration trigger conditions; S5, determine whether the resting time meets the calibration trigger condition; S6, determine whether the vehicle usage cycle meets the calibration trigger conditions; S7, charge to the user-set charging limit; S8, perform full charge calibration; S9, resets counter and timer after full charge calibration.

[0073] In this embodiment of the application, the vehicle charging port is connected to charging equipment such as a charging pile. When charging is started, the process proceeds to step S1. The battery management system first obtains the charging limit currently set by the user to determine whether the charging limit currently set by the user meets the conditions for full charge calibration. If the charging limit is lower than the battery's full charge threshold, such as 100%, then full charge calibration is performed and the process proceeds to step S2. Otherwise, if the charging limit is equal to the battery's full charge threshold, such as 100%, the process proceeds directly to step S8 to perform full charge calibration.

[0074] In the specific implementation, the full charge calibration judgment is performed, proceeding sequentially to steps S2 to S6. Ambient temperature is the primary factor in determining the calibration trigger condition. In step S2, it is determined whether the ambient temperature meets the calibration trigger condition. If the vehicle's ambient temperature meets the calibration trigger condition, the process proceeds to step S8 to perform full charge calibration. If the vehicle's ambient temperature does not meet the calibration trigger condition, the process proceeds to step S3 according to a preset order to determine whether the driving style meets the calibration trigger condition. If the user's driving style meets the calibration trigger condition, the process proceeds to step S8 to perform full charge calibration. If the user's driving style does not meet the calibration trigger condition, the process continues to determine the next calibration trigger condition, proceeding to step S4 according to a preset order to determine whether the mileage meets the calibration trigger condition. If the vehicle's mileage meets the calibration trigger condition, the process proceeds to step S8 to perform full charge. If the vehicle's mileage does not meet the calibration trigger condition, the system continues to determine the next calibration trigger condition, proceeding to step S5 in a preset order to determine if the resting time meets the calibration trigger condition. If the resting time meets the calibration trigger condition, the system proceeds to step S8 to perform full-charge calibration. If the resting time does not meet the calibration trigger condition, the system continues to determine the next calibration trigger condition, proceeding to step S6 in a preset order to determine if the vehicle usage cycle meets the calibration trigger condition. If the vehicle usage cycle meets the calibration trigger condition, the system proceeds to step S8 to perform full-charge calibration. If the usage cycle does not meet the calibration trigger condition, all influencing factors and calibration trigger conditions have been determined, and the full-charge calibration requirement has not been met. The system then proceeds to step S7 to charge to the user-set charging limit. Full-charge calibration is not performed during this charge, and the system waits for the next charge to re-determine the trigger condition. After full-charge calibration, the counter and timer are reset to ensure accurate determination of the calibration trigger condition during the next charge.

The third judgment module is used to determine if the vehicle's mileage exceeds the fourth threshold within a preset period, in which case the vehicle's mileage meets the third calibration trigger condition. The fourth judgment module is used to determine if the vehicle's stationary time exceeds the fifth threshold within a preset period, in which case the vehicle's stationary time satisfies the fourth calibration trigger condition.

[0079] Optionally, the calibration prompt module 230 includes: The prompt submodule is used to end the judgment and send a prompt message to the user to perform full charge calibration if the vehicle meets any of the calibration trigger conditions; wherein, the prompt message is displayed locally on the vehicle's infotainment system or on a remote terminal, and is used by the user to confirm whether to perform full charge calibration.

[0080] Optionally, the control calibration module 240 includes: The adjustment submodule is used to adjust the charging limit of this charge from the user-set charging limit to the full charge calibration threshold in response to the user's confirmation operation of the prompt information.

[0082] The battery power calibration device provided in this application obtains the user's currently set charging limit when the vehicle is in a charging state. If the charging limit is lower than the battery's full charge threshold, the device checks whether the vehicle meets preset calibration trigger conditions one by one in a preset order. The preset calibration trigger conditions are set based on at least one of the following factors: ambient temperature, driving style, mileage, idle time, and vehicle usage cycle. If the vehicle meets any calibration trigger condition, the device sends a prompt message to the user to perform full charge calibration. In response to receiving the user's confirmation of the prompt message, the device controls the vehicle to perform full charge calibration. This embodiment of the application, when the vehicle is in a charging state, determines whether the user's currently set charging limit meets the conditions for full charge calibration. Therefore, even when the user selects a non-full charge charging limit, it efficiently and systematically triggers full charge calibration by considering multiple factors affecting the accuracy of the range display. This reasonable and automatic triggering of full charge calibration effectively reduces battery life damage caused by prolonged full charging. Appropriate full charge calibration effectively corrects deviations in battery power estimation, improving the accuracy of the range display. This avoids the contradiction between prolonged full charging causing battery life damage and inaccurate battery power display due to insufficient charging.
