[0002] With the rapid development of the new energy vehicle industry, power batteries are increasingly used in the automotive field. Power batteries are the "heart" of new energy vehicles, and their performance and service life directly affect the vehicle's range and cost of use. Therefore, it is crucial to manage power batteries throughout their life cycle.

[0003] At present, the management of power batteries in new energy vehicles mainly relies on battery management systems, which can perform basic battery status monitoring and data analysis. It mainly focuses on the performance of the battery during use, that is, it only evaluates the performance of the battery based on the parameters of a single battery during use. This method does not comprehensively evaluate the entire life cycle of the battery, resulting in low battery management utilization. Summary of the invention

[0004] The present application provides a method, system, medium and equipment for the full life cycle management of a power battery, which enables a comprehensive assessment of the battery at all stages of its life cycle, including use, maintenance and scrapping and recycling, and improves the utilization rate of battery management.

[0005] In a first aspect, the present application provides a method for managing the entire life cycle of a power battery, the method comprising: obtaining battery data of power batteries in a plurality of vehicles of the same batch, and environmental parameters of each of the vehicles;

[0010] By adopting the above technical solution, the battery data and environmental parameters of multiple vehicles in the same batch are obtained, the influence of environmental factors on battery aging is fully considered, and the defect of one-sided evaluation caused by analyzing only the data of a single vehicle is avoided. The processing type of the power battery is determined according to the battery data of a preset number of vehicles and the corresponding environmental parameters, which can effectively judge whether the battery needs to be repaired or scrapped and recycled, and avoid continuing to use batteries with serious performance degradation or scrapping them prematurely. For batteries determined to be to be repaired, differentiated maintenance strategies are formulated according to battery data to improve the pertinence and efficiency of maintenance and extend the battery life.

For batteries determined to be to be recycled, a recycling report is generated according to the battery data, the battery is valued and classified, and the battery utilization rate is improved. The battery usage recommendations or recycling reports are sent to the vehicle terminal, which provides guidance and basis for subsequent battery use and recycling processing, realizes the comprehensive management of batteries in all stages of the entire life cycle, such as use, maintenance, scrapping and recycling, and improves the battery management utilization rate.

[0011] Optionally, determining the processing type of the power batteries in each of the vehicles under the corresponding environment based on the battery data of a preset number of vehicles and the corresponding environmental parameters includes: determining the health value of each power battery under the corresponding environment and the average health value of the power batteries of a preset number of vehicles under the corresponding environment based on the battery data of each of the vehicles and the corresponding environmental parameters; when the health value is greater than a health threshold and less than the average health value, determining that the processing type of the power battery under the corresponding environment is a type to be repaired; when the health value is less than or equal to the health threshold, determining that the processing type of the power battery under the corresponding environment is a battery to be recycled.

[0012] By adopting the above technical solution, based on the battery data of the power battery and the corresponding environmental parameters, the health value of the battery and the average health value of a preset number of vehicles in the environment are determined, and based on the average health value and the health threshold, it is determined whether the battery is to be repaired or recycled, and the batteries are classified and managed in a refined manner. This on-demand classification is conducive to maximizing the exploration and utilization of the residual value of the battery and avoiding extensive waste of resources.

[0013] Optionally, the battery data includes battery voltage, battery current, battery temperature, charge and discharge times, and remaining capacity, and the environmental parameters include ambient temperature, ambient humidity, and vehicle amplitude. According to the battery data of each vehicle and the corresponding environmental parameters, determining the health value of each power battery in a corresponding environment includes: substituting the battery voltage, battery current, battery temperature, charge and discharge times, remaining capacity, and the ambient temperature, ambient humidity, and vehicle amplitude into a health value calculation formula to obtain the health value of the power battery;

[0014] The health value calculation formula is:

[0015] Among them, SOH is the health value, α, β, γ, δ, ∈ are the physical parameters for adjusting the battery, η, θ, ι are the environmental adjustment parameters, V max is the maximum battery voltage, V b is the battery voltage, V min is the minimum battery voltage, I is the battery current, T S is the standard temperature, T b is the battery temperature, F b is the number of charge and discharge times, F max is the maximum charge and discharge times, C b is the remaining capacity, C s is the standard capacity, T e is the ambient temperature, H e is the ambient humidity, H s is the standard humidity and V is the vehicle amplitude.

[0016] By adopting the above technical solution, the health value calculation formula that comprehensively considers the internal parameters of the battery and external environmental factors can more accurately reflect the complex mapping relationship between the internal and external conditions of the battery and its health status, thereby obtaining a more reliable health value assessment result.

[0017] Optionally, if the processing type of the power battery is a battery to be repaired, a corresponding maintenance strategy for the power battery is determined according to the battery data, and the maintenance strategy is sent to a management terminal, including: if the processing type of the power battery is a battery to be repaired, the maintenance level of the power battery is determined according to the health value, and the maintenance type is determined according to the battery data; required maintenance tools are determined based on the maintenance level and the maintenance type; a maintenance strategy is generated based on the maintenance level, the maintenance type and the maintenance tools, and the maintenance strategy is sent to the management terminal, so that the management terminal determines a maintenance worker in the idle work dispatch list according to the maintenance strategy.

[0018] By adopting the above technical solution, for power batteries whose evaluation results are "batteries to be repaired", the decision module will formulate a detailed maintenance strategy based on their health values, battery data and other information, and send the strategy content to the management terminal to guide the subsequent maintenance dispatch process and realize the use and maintenance management of the battery during use.

[0020] By adopting the above technical solution, after the maintenance worker completes the maintenance work on the power battery, the decision module will receive the maintenance completion signal sent by the management terminal, and then automatically start the vehicle's battery test mode, and obtain the power battery data in this test mode after a preset time, providing a quality feedback mechanism for the maintenance work and realizing effective management of the maintenance stage.

[0021] Optionally, generating the usage suggestion of the power battery based on the current battery data includes: comparing each dimensional parameter in the current battery data with each dimensional standard parameter corresponding to the vehicle to determine a dangerous dimensional parameter; and obtaining a historical battery usage record corresponding to the dangerous dimensional parameter;

[0022] The historical battery usage records are analyzed to generate usage recommendations for the power battery.

[0023] By adopting the above technical solution, when generating usage recommendations for the power battery, the current parameter data of each dimension of the power battery is compared with the standard parameters of the vehicle model, and dangerous dimension parameters that deviate from the standard are screened out. Based on the historical usage records of these dangerous dimension parameters, targeted usage recommendations are generated. This can accurately identify the weak links of the battery, enable the recommendation content to directly focus on solving practical problems, and effectively realize the management of the usage recommendation process.

[0024] Optionally, if the processing type of the power battery is a battery to be recycled, a recycling report for the power battery is generated based on the battery data, including: if the processing type of the power battery is a battery to be recycled, obtaining the historical maintenance record of the power battery; based on the historical maintenance record, evaluating the physical value and safety value of the power battery; based on the various dimensional parameters in the battery data, evaluating the performance value of the power battery; combining the physical value, the safety value and the performance value, calculating the recycling value of the power battery; determining the recycling type of the power battery based on the recycling value, and generating a recycling report for the power battery based on the recycling value and the recycling type.

[0043] The embodiments of the present application can be applied but not limited to various fields that require power batteries or energy storage batteries. It can realize the comprehensive management of the entire life cycle of the battery and improve the battery management utilization rate. For example, it can be directly applied to the power battery management of new energy passenger vehicles, commercial vehicles and other vehicles.

[0044] The battery management background to which the embodiment of the present application is applied can manage all power batteries, which can be batteries from the same batch produced by a manufacturer or batteries that need to be managed. The battery management background can include a data communication module, a central database, an interactive interface, a security and management module, a data analysis module, etc. The data communication module is used to collect the basic information and performance data of each power battery in real time, and can use encrypted communication protocols such as TLS / SSL to ensure the security of data transmission; the central database is used to store the historical and real-time data of all power batteries; the interactive interface is used for administrators to interact and display all battery data; the data analysis module is used to analyze and process the acquired battery data, and the security and management module is used for security and user access authority control.

[0045] Please refer to Figure 1 , a flow chart of a method for managing the life cycle of a power battery is proposed. The method can be implemented by a computer program, a single-chip microcomputer, or run on a power battery life cycle management system. The computer program can be integrated in the battery management background, or run as an independent tool application. Specifically, the method includes steps 10 to 50, and the steps are as follows:

[0046] Step 10: Obtain battery data of power batteries in multiple vehicles of the same batch, as well as environmental parameters of each vehicle.

[0047] In the embodiment of the present application, power batteries refer to batteries that need to be managed, such as power batteries produced from the same production line and the same batch by a battery manufacturer. These batteries have the same design parameters, materials and manufacturing processes and can be regarded as a batch of power batteries for centralized management.

[0048] Specifically, the power batteries of the same batch are consistent in production and initial performance, but in actual use, due to the different environments, such as temperature, humidity, vibration and other factors, the degree of battery aging and health status are different. Only by obtaining the battery data and usage environment parameters of multiple vehicles in the same batch can the overall health level of the batch of batteries be fully and accurately evaluated. The battery data of each vehicle can be collected in real time through the on-board sensors and vehicle communication modules, including battery voltage, current, temperature, charge and discharge times, remaining capacity, etc.; at the same time, the temperature, humidity, vibration amplitude and other parameters of the vehicle's environment can be obtained. These data are uploaded to the battery management platform through the wireless communication network. The battery management platform can store the battery data and environmental parameters of all vehicles in the same batch in the corresponding database, and manage and analyze these data in a unified manner.

[0049] Step 20: According to the battery data of a preset number of vehicles and the corresponding environmental parameters, determine the processing type of the power battery in each vehicle under the corresponding environment.

[0050] After obtaining the battery data and environmental parameters of multiple vehicles in the same batch, the treatment type of each vehicle's power battery in its use environment is determined for a preset number of vehicles based on their battery data and corresponding environmental parameters. Although the batteries of different vehicles belong to the same batch, there will be a certain difference in the health of the batteries due to differences in the use environment. By analyzing the data of a certain number of vehicles, the overall health level of the batch of batteries can be comprehensively evaluated, providing a basis for determining a reasonable treatment type.

[0051] The environmental parameters corresponding to the preset number of vehicles refer to these vehicles in similar use environments, which can also be understood as being within a certain range of environmental parameters. When determining the treatment type of each vehicle's power battery, a preset number of vehicles will be screened out first to ensure that the ambient temperature, humidity, vibration and other parameters of these vehicles are within a similar range. For example, the ambient temperature is 20-30℃, the humidity is 40%-60%, and the vibration is below a certain threshold. Analyzing a batch of vehicles in a similar environment can truly reflect the health level of the batch of batteries in this environment, thereby determining a reasonable treatment type.

[0052] Specifically, based on the preset health value algorithm, the battery data (such as voltage, current, temperature, number of cycles, capacity, etc.) and environmental parameters (such as ambient temperature and humidity, vibration, etc.) of each vehicle are substituted into the calculation to obtain the health value of the vehicle's power battery in its operating environment. Then the average health value of the batteries of a preset number of vehicles is calculated. By comparing the health value of each vehicle's battery with the average health value and the preset health threshold, it can be determined whether the power battery is a healthy battery, a battery to be repaired, or a battery to be recycled, that is, its treatment type is determined. By dividing the power batteries into different treatment types, differentiated management strategies can be adopted for different states, thereby improving the pertinence and efficiency of management.

[0053] Based on the above embodiment, as an optional embodiment, the step of determining the processing type of the power battery in each vehicle under the corresponding environment according to the battery data of a preset number of vehicles and the corresponding environmental parameters may further include the following steps:

[0054] Step 201: Determine the health value of each power battery in the corresponding environment and the average health value of the power batteries of a preset number of vehicles in the corresponding environment according to the battery data of each vehicle and the corresponding environmental parameters.

[0055] The actual health status of the battery depends not only on the parameters of the battery itself, but also needs to be comprehensively evaluated in combination with external conditions such as the use environment. It fully reflects the overall health level of the batch of batteries in different environments and provides an accurate basis for determining the treatment type.

[0056] Specifically, battery data mainly includes battery voltage, battery current, battery temperature, charge and discharge times, and remaining capacity, which reflects the operating status of the battery under the actual working environment and usage conditions; environmental parameters include ambient temperature, ambient humidity, and vehicle amplitude, which reflect the environmental conditions of the power battery. Substitute the battery voltage, battery current, battery temperature, charge and discharge times, remaining capacity, ambient temperature, ambient humidity, and vehicle amplitude into the health value calculation formula to obtain the health value of the power battery. Then, for a preset number of vehicles, calculate the health values ​​of their batteries respectively, and then calculate the arithmetic mean of these health values ​​as the average health value of the batch of batteries in this environment.

[0057] The health value calculation formula is:

[0058] Among them, SOH is the health value, α, β, γ, δ, ∈ are the physical parameters for adjusting the battery, η, θ, ι are the environmental adjustment parameters, V max is the maximum battery voltage, V b is the battery voltage, V minis the minimum battery voltage, I is the battery current, T S is the standard temperature, T b is the battery temperature, F b is the number of charge and discharge times, F max is the maximum charge and discharge times, C b is the remaining capacity, C s is the standard capacity, T e is the ambient temperature, H e is the ambient humidity, H s is the standard humidity and V is the vehicle amplitude.

[0059] The health value calculation formula consists of two parts. The first part is to calculate the impact of battery data on battery health, where α is used to adjust the impact of voltage deviation on SOH, and the impact of voltage is evaluated by comparing the relationship between battery voltage and the maximum and minimum voltage values. β is used to adjust the impact of current on SOH. The square term of current indicates the nonlinear characteristics of the impact of current on battery health. γ is the weight factor of temperature difference, which reflects the impact of temperature on battery health through the deviation between the operating temperature and the standard temperature. δ is the weight factor of charge and discharge times, which reflects the aging of the battery through the number of charge and discharge times and the maximum number of charge and discharge times completed by the battery. ∈ is the battery capacity factor, which reflects the loss of battery capacity through the current capacity and the standard capacity of the battery. The second part is to calculate the impact of environmental parameters on battery health, where η is the temperature weight factor, which reflects the impact of temperature on battery performance through the difference between the external ambient temperature and the standard temperature, θ is the humidity weight factor, which reflects the impact of temperature on battery health through the ratio of the external humidity temperature to the standard humidity, and ι is the amplitude weight factor, which reflects the impact of amplitude on battery health by multiplying with the amplitude of the vehicle.

[0060] In summary, the formula combines these parameters of the battery dimension and the environmental dimension to derive a percentage value between 0 and 100, which represents the health status of the battery. 1 minus the sum of all these influencing factors (adjusted by weights), multiplied by 100, gives the battery's health value (SOH). The closer this value is to 100%, the better the health of the battery; the lower the health value, the battery's performance may be degraded and require maintenance or replacement. The multiple influencing factors and weight factors included in the calculation formula enable it to comprehensively consider different battery degradation parameters to provide a more comprehensive and accurate health status assessment.

[0061] Step 202: When the health value is greater than the health threshold value and less than the average health value, it is determined that the processing type of the power battery in the corresponding environment is a type to be repaired.

[0062] Specifically, the health value can comprehensively reflect the operating status and performance level of the battery. When the health value is high, it means that the battery is operating normally under the actual working environment and usage conditions, and the performance has not shown obvious attenuation. At this time, the battery is still in a healthy state and does not require immediate maintenance or scrapping measures. It can continue to be used normally.

[0063] In the embodiment of the present application, a health threshold is pre-set as the threshold of a healthy battery, and this threshold can be adjusted according to factors such as the battery type and the design operating conditions. For example, for a certain power battery, when its comprehensive health value reaches 85 points (out of 100 points), it can be considered that the battery is in good condition and the processing type is a healthy battery. When the health value of the power battery is greater than the health threshold but less than the average health value, the processing type of the power battery is determined as a type to be repaired, because the health value is higher than the threshold, indicating that the battery can still be used, but lower than the average value, indicating that it is in poor health compared to other batteries in the same batch, and may accelerate aging if not repaired in time. Therefore, taking maintenance measures for this part of the battery can appropriately extend its service life.

[0064] Step 203: When the health value is less than or equal to the health threshold, it is determined that the processing type of the power battery in the corresponding environment is a battery to be recycled.

[0065] Specifically, when the health value is less than or equal to the health threshold, it means that the power battery has been seriously aged and its performance has greatly declined. Even if maintenance measures are taken, it is difficult to completely restore it. Continuing to use it is not only inefficient, but may also bring safety hazards. At this time, the best way to deal with it is to recycle these batteries, that is, to determine their treatment type as batteries to be recycled, which can avoid waste of resources and classify them for treatment, and maximize the reuse of batteries and materials.

[0066] Step 30: If the processing type of the power battery is a battery to be repaired, determine the corresponding maintenance strategy for the power battery according to the battery data, and send the maintenance strategy to the management terminal; obtain the current battery data of the power battery after maintenance, and generate usage recommendations for the power battery based on the current battery data.

[0067] A battery to be repaired refers to a battery whose health value is greater than the health threshold and less than the average health value after evaluation by the battery management background. It has some faults or performance degradation, but the problem has not yet worsened to the point where it cannot be repaired. Targeted repair measures need to be taken to extend the service life of the battery.

[0068] The maintenance strategy refers to a series of specific maintenance plans and guidelines formulated by the battery management background for the power battery that has been identified as a battery to be repaired, based on the type and degree of its fault. The maintenance strategy may include the maintenance level, maintenance type, tools and materials required for maintenance, expected maintenance results, etc.

[0069] The management terminal refers to a terminal device connected to the battery management background, which is used to receive and execute various management instructions and strategies issued by the background. When the battery management background determines that the power battery is a battery to be repaired, it will formulate a maintenance strategy for the power battery and send it to the maintenance station management terminal. The management terminal can automatically assign maintenance personnel, and the maintenance personnel can view the policy content on the management terminal, including maintenance level, maintenance type, operation steps, required tools and materials, etc., and carry out maintenance work in an orderly manner on site according to these instructions.

[0070] Specifically, when it is determined that the processing type of the power battery is a battery to be repaired, the type and degree of the fault is evaluated based on the battery data of the power battery, and a targeted maintenance strategy is formulated. The strategy includes specific guidelines such as maintenance level (mild, moderate, severe), maintenance type (replacement of single battery, end repair, thermal runaway repair, etc.), required tools and materials. The battery management background sends the maintenance strategy information to the management terminal of the maintenance station. After the maintenance staff obtains the maintenance strategy, they perform on-site maintenance operations on the faulty battery according to the maintenance methods and steps therein, aiming to eliminate or alleviate the battery failure and restore its normal performance. After the maintenance is completed, the current battery data of the repaired power battery is fed back to the battery management background. Based on these new battery data, the battery repair effect and remaining performance are evaluated, and special usage recommendations are generated. Usage recommendations include the battery's safe operating temperature range, charging and discharging parameters, operating condition restrictions, etc., aiming to maximize the remaining performance of the battery and avoid similar failures from happening again.

[0071] Based on the above embodiment, as an optional embodiment, if the processing type of the power battery is a battery to be repaired, the step of determining the corresponding maintenance strategy of the power battery according to the battery data may further include the following steps:

[0072] Step 3011: If the processing type of the power battery is a battery to be repaired, the maintenance level of the power battery is determined according to the health value, and the maintenance type is determined according to the battery data.

[0073] Specifically, when it is determined that the processing type of the power battery is a battery to be repaired, not all of them will take the same maintenance measures. Instead, the maintenance level and maintenance type are determined based on the specific battery data of the power battery, so as to formulate a more accurate and targeted maintenance strategy. Because different batteries to be repaired may have different degrees and natures of faults, by formulating personalized maintenance strategies in a targeted manner, it is possible to ensure the quality of maintenance, reduce maintenance investment, and improve resource utilization efficiency. The maintenance level of the power battery can be determined according to its health value. For example, a battery with a score of 75-85 is a light maintenance; a battery with a score of 65-75 is a moderate maintenance; and a battery with a score of 60-65 is a severe maintenance. The lower the health value, the more serious the battery failure, and the greater the maintenance effort required. By determining the maintenance level, a basis can be provided for the subsequent formulation of maintenance types.

[0074] Combined with the detailed battery data of the power battery, the fault type is further analyzed to determine the type of maintenance. These battery data include operating data such as battery usage history, working environment, charge and discharge curves, internal resistance readings, as well as detection data such as thermal runaway degree, monomer consistency, and end joint conditions. Through data analysis, the specific fault type of the battery can be determined, such as monomer battery failure, poor end contact, thermal runaway, etc., so as to formulate targeted maintenance types, such as monomer battery replacement for individual monomer failures; end maintenance to solve the problem of poor contact at the battery end; thermal runaway maintenance to deal with serious thermal runaway problems of the battery. Different maintenance types will take different operating steps and use different tools and spare parts for repair construction.

[0075] Step 3012: Determine the required maintenance tools based on the maintenance level and maintenance type.

[0076] Specifically, different maintenance levels and types correspond to different maintenance work contents and difficulties, and the types and quantities of tools required will also vary. Only when the required tools are fully prepared can on-site maintenance work be carried out smoothly and efficiently, thereby ensuring the quality of maintenance and avoiding waste of resources. A maintenance tool library can be pre-set, which is classified and stored by tool type, model, purpose, etc. After determining the maintenance level and maintenance type of the power battery, the corresponding required tool list is automatically retrieved from the tool library. For example, for the replacement of single cells in light maintenance, only basic battery disassembly and assembly tools, spot welding equipment, etc. may be needed; while thermal runaway maintenance in heavy maintenance requires professional X-ray detectors, radiation shielding equipment, etc. Different tool combinations are suitable for different maintenance operations. The tool list not only lists the tool name, but also includes specific information such as the required quantity, model specifications, and corresponding instructions for use, safety precautions, and other guidance content. With these detailed information, on-site maintenance personnel can prepare tools in advance to ensure that maintenance work is carried out in an orderly manner.

[0077] Step 3013: Generate a maintenance strategy based on the maintenance level, maintenance type and maintenance tools, and send the maintenance strategy to the management terminal so that the management terminal determines the maintenance worker in the idle work assignment list according to the maintenance strategy.

[0078] Specifically, in order to ensure that on-site maintenance work can be carried out in an orderly manner, all relevant maintenance information is unified into a maintenance strategy, which is not only convenient for the management terminal to receive and process it centrally, but also can avoid omissions or errors in information transmission, thereby providing accurate guidance for on-site operations. First, the corresponding strategy template file will be retrieved from the strategy template library according to the previously determined maintenance level, maintenance type and tool list. The template includes the basic framework of the strategy and various modules, such as maintenance target description, fault analysis, operation instructions, precautions, etc. The specific information required for this maintenance is filled into the corresponding modules one by one, and other explanatory content is supplemented as needed to generate a maintenance strategy specifically for the power battery. The maintenance strategy may include: basic battery information and fault overview, maintenance level, maintenance type, specific steps for maintenance operations, lists of required tools and spare parts, safety precautions for operations, expected maintenance effects, other instructions, etc. After the maintenance strategy is reviewed and confirmed, it will be sent to the management terminal. After receiving the maintenance strategy, the management terminal will determine and assign the corresponding maintenance workers to carry out the maintenance work from the idle dispatch list of the maintenance workers of this station according to the difficulty and complexity of the operation required in the strategy content.

[0079] Based on the above embodiment, as an optional embodiment, the step of obtaining the current battery data of the power battery after maintenance may further include the following steps:

[0080] Step 3021: After receiving the maintenance completion signal sent by the management terminal, the battery test mode of the vehicle is turned on.

[0081] After the maintenance work is completed on site, the management terminal will send a maintenance completion signal to the battery management background. After the maintenance, it is necessary to evaluate whether the battery performance has been improved or restored through testing to determine whether the maintenance has achieved the expected effect. Only when the maintenance effect is good can the next step of use management be continued. The maintenance process will have a certain impact on the battery. In order to fully and accurately understand the current status of the battery after maintenance, it is necessary to collect new battery data after maintenance in the test mode. This data will provide a basis for the subsequent formulation of usage strategies. The battery test mode can simulate the real working environment and working conditions, conduct a comprehensive and comprehensive test of the battery, discover potential safety hazards, and provide support for the formulation of usage strategies.

[0082] Specifically, when the battery management background receives the maintenance completion signal sent by the management terminal, it will immediately send the test mode start command to the vehicle terminal loaded with the maintenance battery. After receiving the command, the vehicle terminal will automatically switch to the battery test mode and start the battery module to perform a series of preset test processes, such as cyclic charging and discharging, loading high current conditions, thermal runaway pressure testing, etc., to simulate the various working conditions of the battery in actual application scenarios. At the same time, various detection sensors on the vehicle will collect multi-dimensional data such as battery temperature, voltage, current, internal resistance, etc. in real time, and upload these test data to the background in real time through the vehicle terminal.

[0083] Step 3022: After a preset time period, obtain battery test data of the power battery in the battery test mode.

[0084] Specifically, the test process in the battery test mode often takes a certain amount of time to be fully executed, including multiple links such as charge and discharge cycles, high current loading, temperature and pressure experiments, and each link takes a period of time. At the same time, in order to ensure the accuracy of the test data, the battery needs to operate under relatively stable conditions during these tests. Therefore, if the data is read when the test mode is just started, it is likely that only a small amount of irregular fragmented data will be obtained because the test process has not yet started or the test conditions have not yet stabilized, which makes it difficult to truly reflect the overall performance of the battery. Therefore, a time period can be pre-set, such as 12 hours or 24 hours, so that the battery can be fully operated in the test mode for a period of time, and then all the test data of the power battery in the time period can be uniformly obtained. The vehicle terminal will roll and store the multi-dimensional data such as battery voltage, current, temperature, internal resistance, etc. collected during the test according to the preset time granularity (such as 5 minutes). When the battery management background decision module issues a read request after the preset time period, the vehicle terminal will upload all the test data in the time period together, thereby obtaining the battery test data of the power battery in the battery test mode.

[0085] Step 3023: If the battery test data is abnormal, a re-repair prompt message is sent to the management terminal;

[0086] Step 3024: If the battery test data is normal, the battery test data is used as the current battery data of the power battery.

[0087] In order to ensure that the performance and safety of the battery to be used fully meet the use requirements, if the repaired battery has abnormal test data due to failure to achieve the expected repair effect or other hidden dangers, then putting it directly into use will undoubtedly bring great safety risks. Only after confirming that the battery is in good condition through data evaluation can it be used safely.

[0088] Specifically, the obtained battery test data is compared with the normal value range in the existing battery standard database to check whether the core parameters such as voltage, temperature rise, internal resistance, etc. are within a reasonable range and whether there are abnormal fluctuations or exceeding the standard. At the same time, these test data will be comprehensively analyzed in combination with previous maintenance records, fault analysis and other information to determine whether the original fault point has been resolved and whether potential new faults have occurred. If the analysis results show that the test data has obvious abnormalities and does not meet the safety requirements, then it will be determined that the maintenance effect is not ideal, and a reminder message for re-maintenance will be sent to the maintenance station management terminal for the battery. After receiving the prompt, the management terminal will arrange for a special person to perform a second or even multiple maintenance on the battery until the test data returns to normal. On the contrary, if the test data analysis results show that the battery performance indicators are normal and no abnormal problems are found, it is determined that the maintenance has achieved the expected effect and the power battery can be put into normal use. At this time, this batch of test data will be stored for a long time and used as the latest valid battery data of the power battery to provide a reference for the next step of formulating the use strategy.

[0089] Based on the above embodiment, as an optional embodiment, the step of generating a usage recommendation of a power battery based on current battery data may further include the following steps:

[0090] Step 3031: Compare the dimensional parameters in the current battery data with the dimensional standard parameters corresponding to the vehicle to determine the dangerous dimensional parameters.

[0091] Specifically, compare the parameters of each dimension in the current battery data with the standard parameters of the vehicle type corresponding to the power battery, and pay special attention to those dangerous dimension parameters that are close to the lower limit of the normal range. Because after maintenance, all the parameters of the dimensions may be within the normal range, but there are also some dimensional parameters that are close to the lower limit of the normal range. These dimensional parameters are regarded as dangerous dimensional parameters. The dangerous dimensional parameters need to be paid attention to in subsequent use. If they continue to be used in the previous way, the power battery may soon be in an abnormal state in this dimension.

[0092] A vehicle battery standard parameter library can be set up to store the standard range of various core performance parameters according to different vehicle models and battery models, such as the voltage range, temperature rise range, and discharge rate range of the battery pack of the vehicle model. The current voltage, temperature, internal resistance, cycle life and other multi-dimensional data parameters of the power battery are compared one by one with the standard range values ​​of the vehicle model to which the battery belongs in the parameter library. Those parameters within the normal range will be marked as "normal"; for parameters that are within the normal standard range but close to the lower limit, such as the minimum allowable voltage of the battery pack is only 0.05V higher than the lower limit, it will be marked as "dangerous" level. All parameters marked as dangerous levels are dangerous dimension parameters that need to be focused on. These parameters reflect that the performance of the battery in certain dimensions is close to the limit state. If it is not used in accordance with the standard method, it is very likely that the performance indicators of this dimension will exceed the lower limit range, causing safety hazards.

[0093] Step 3032: Obtain the historical battery usage records corresponding to the risk dimension parameters.

[0094] Step 3033: Analyze the historical battery usage records and generate power battery usage recommendations.

[0095] The reasons why the performance of different dangerous dimension parameters approaches the lower limit may vary. By analyzing historical usage records, it is possible to more accurately determine whether the performance degradation is due to certain usage behaviors or the natural aging of the battery itself, so as to make targeted usage recommendations. Since it is difficult to predict the future trend of dangerous dimension parameters by simply looking at current data, analyzing historical records helps to discover the evolution of parameters, thereby evaluating their development status and taking timely countermeasures.

[0096] Specifically, first, relevant data of the power battery in the past use process will be retrieved from the battery usage record library, such as the discharge capacity, temperature rise curve, voltage change, etc. under different working conditions, and sorted in chronological order. Then, for the determined dangerous dimension parameters, the change trend in the historical data will be traced back and analyzed. For example, if the dangerous dimension is too high temperature rise, the module will analyze the temperature rise change of the battery at different discharge powers and ambient temperatures to determine its relevance to the usage mode. In addition, the potential causes of dangerous parameters can be comprehensively analyzed and diagnosed in combination with the model characteristics, service life, fault maintenance records, etc. of the battery. Based on a comprehensive analysis, usage recommendations for the power battery are generated, and clear usage recommendations are made for power batteries with dangerous dimension parameters, such as limiting the maximum allowable power or maximum discharge capacity of the battery, shortening the use cycle and appropriately increasing the rest time, etc.

[0097] Step 40: If the processing type of the power battery is a battery to be recycled, a recycling report of the power battery is generated according to the battery data.

[0098] Specifically, if the processing type of the power battery is a battery to be recycled, it means that it can no longer be used. For batteries that can no longer be used, there may be some residual value, such as metal shells, positive electrode materials and other recyclable parts. Differentiated recycling reports can be formulated according to factors such as battery type and fault conditions. The reasons for its classification into the category to be recycled can be determined based on information such as the historical use records and fault repair records of the power battery, such as the exhaustion of the cycle life and serious damage to the main body. Then the latest test data of the battery will be analyzed, and core parameters such as voltage, temperature, and internal resistance will be extracted and compared with the standard values ​​to analyze its performance status and potential risk points. On this basis, a complete recycling report will be compiled according to the preset recycling report template. The main contents of the report may include: 1. Basic information of the battery, 2. Explanation of the reasons for scrapping, 3. Current performance data of the battery, 4. Existing safety hazards and preventive measures, 5. Disassembly and disposal suggestions, 6. Analysis of the recycling value of residual materials, etc.

[0099] Based on the above embodiment, as an optional embodiment, if the processing type of the power battery is a battery to be recycled, the step of generating a recycling report of the power battery according to the battery data may further include the following steps:

[0100] Step 401: If the processing type of the power battery is a battery to be recycled, the historical maintenance record of the power battery is obtained.

[0101] Specifically, since it is difficult to fully evaluate the true residual value of a battery based on the latest test data alone, the combination of historical maintenance records can restore the entire process from the battery being put into use to being scrapped, which is more conducive to making an accurate judgment on its condition. The maintenance records record in detail the various types of failures that have occurred in the battery, as well as the time and working conditions when the failure occurred. Analyzing these data helps to clarify the cause of the failure and determine the possibility of the failure worsening, thereby providing more basis for value assessment. Especially for batteries with serious faults or defects, understanding their specific problems in combination with maintenance records can better assess the potential safety hazards during the disassembly process, thereby formulating a more reasonable safety disassembly plan. All previous maintenance records of the scrapped battery can be retrieved from the historical maintenance record library, including maintenance time, failure cause analysis, maintenance measures taken, maintenance effect evaluation, and other content.

[0102] Step 402: Based on historical maintenance records, assess the physical value and safety value of the power battery.

[0103] Specifically, combined with historical maintenance records, the physical value and safety value of the battery are evaluated separately. For physical value assessment: it will analyze whether the battery has suffered serious external physical damage from commissioning to scrapping, such as shell cracks, pole deformation, etc. If there is no such damage, or only a slight bump, the module will determine that the overall structure of the battery shell, box, etc. is intact, and its metal materials and positive and negative active materials may still have a certain physical recycling value. For example, according to the pre-set scoring rules, combined with factors such as the appearance integrity of the battery, the proportion of metal materials, and the preservation of positive and negative electrode materials, a physical value score can be given according to a scoring range of 0-100. For example, a complete and undamaged battery shell can get 50 points, and 20 points can be added if the positive and negative materials are well preserved, but if the overall structure is severely damaged, it will directly get 0 points. In the end, the higher the score of this item, the greater the actual physical value of the battery's metals, materials, etc.

[0104] For safety value assessment: combined with the battery failure repair history, the focus will be on analyzing whether the battery has a record of thermal runaway, electrolyte leakage, internal short circuit, etc. If so, there is a high risk of disassembly safety. At the same time, it will also be evaluated whether the battery has serious internal defects that cannot be repaired, such as positive and negative electrode material peeling, which will also affect the safety of the subsequent disassembly process. The safety value will also refer to the preset rules, combined with whether the battery has risk records such as thermal runaway and leakage in the maintenance records, and whether key components such as positive and negative electrodes have irreparable defects, to give a safety value score of 0-100. If the battery has never had a safety accident in history and there are no obvious defects inside, a higher score can be obtained. Otherwise, the score will be significantly reduced. The higher the score, the lower the risk of safety problems occurring in the subsequent disassembly process.

[0105] Step 403: Evaluate the performance value of the power battery based on the parameters of each dimension in the battery data.

[0106] Specifically, even if the battery is classified as scrapped, if some of its performance parameters are still at a relatively good level, then after targeted secondary use or repair, it may still have a certain residual value in a specific scenario. The current values ​​of key performance parameters such as voltage, temperature, internal resistance, and number of cycles can be extracted from the battery data and compared with the standard values ​​of the battery model. On this basis, a comprehensive evaluation of the applicability of these parameters in different potential reuse scenarios will be conducted to give a performance value score of 0-100. For example, for a battery, if its discharge rate is still at a high level, it may be more suitable for use as an auxiliary power source for energy storage battery packs; if its temperature control capability is good, it may be more suitable for the production of battery-derived materials, etc.

[0107] Step 404: Calculate the recycling value of the power battery by combining the physical value, safety value and performance value.

[0108] Step 405: Determine the recycling type of the power battery based on the recycling value, and generate a recycling report of the power battery according to the recycling value and the recycling type.

[0109] Scoring in a single dimension is inevitably one-sided. Only by taking into account various factors such as physics, safety and performance can the true residual value of a battery be reflected more comprehensively and accurately.

[0110] Specifically, the physical value score, safety value score and performance value score obtained from the previous evaluation are weighted and summed according to a certain weight coefficient to obtain a total score, that is, the recycling value of the battery. For example, the physical value weight can be set to 30%, the safety value weight to 40%, and the performance value weight to 30%. Based on this recycling value, the power battery will be judged and divided into recycling types according to the preset score range. For example, it can be preset that: 80 points or more are "good battery" recycling types, which will be given priority to the reuse channel; 60-79 points are "general battery" recycling types, which will be directed to disassembly and processing; 60 points or less are "defective battery" recycling types, which will be directly harmlessly treated. According to the corresponding recycling type, a final recycling report will be generated, and key information such as the total recycling value score and the corresponding recycling type will be recorded. At the same time, the report content will also include basic information of the battery, historical maintenance records, value assessment results of each dimension, and specific recycling and utilization methods that should be adopted for this type of battery in the future. After the report is reviewed and signed, it will be sent to the corresponding battery recycling center via the Internet, serving as an important basis for guiding the center to plan on-site operations and formulate recycling and utilization plans.

[0111] Step 50: Send the usage suggestion or recycling report to the vehicle terminal.

[0112] Specifically, the communication ID and networking method of the target vehicle are obtained from the vehicle database, and a communication connection with the vehicle terminal is established based on this information. Then, the content data of the previously generated usage recommendation report or recycling report is encapsulated and transmitted to the vehicle terminal through channels such as the Internet or vehicle network in accordance with the standardized communication protocol and data format. After receiving the report data, the vehicle terminal will parse and display it, and adopt different display and interaction methods according to the report type. For example, if it is a usage recommendation report, the vehicle terminal will display the key content such as the battery usage evaluation results and the maintenance measures to be taken to the user in the form of text, charts or voice prompts on the display screen. If it is a recycling report, the vehicle terminal will display the main data of the recycling report in the form of a list, and the user can check the basic parameters, fault analysis, recycling suggestions, etc. of the battery. At the same time, the address of the nearest recycling outlet will be given to facilitate user contact.
