[0023] Before describing the specific embodiments of the present application, the related technologies of the present application are described as follows:

[0024] Based on the extreme gradient boosting decision tree algorithm (eXtreme Gradient Boosting, referred to as XGBoost) using the gradient boosting framework, it aims to provide an efficient, flexible and portable gradient boosting library. XGBoost belongs to the Boosting type of integrated learning method.

[0025] Non-dominated Sorting Genetic Algorithm II (NSGA-Ⅱ) is a genetic algorithm used to solve multi-objective optimization problems. It is an improved version of NSGA and solves the problems of the original NSGA in computational complexity, convergence and parameter setting.

[0026] Non-dominated sorting

[0027] Perform non-dominated sorting on the individuals in the population and divide them into different levels. The higher the level, the higher the priority. Sort and select those solutions that are not dominated by other solutions at the same time on multiple objectives. If a solution is not surpassed by another solution on all objectives, it is non-dominated (or not inferior). In multi-objective optimization, the condition for solution A to dominate solution B is that solution A is not worse than solution B on all objectives and solution A is better than solution B on at least one objective. Compare each candidate solution with other solutions to find those solutions that are not dominated by other solutions. These solutions constitute the first layer of non-dominated frontier (Pareto front or layer). After removing the first layer of non-dominated solutions that have been found, repeat the above process for the remaining solutions to find the second layer of non-dominated solutions. Then continue this process until all solutions are sorted into a certain layer. For the first layer of non-dominated solutions, compare the two fitness values ​​of each solution to find those that are not dominated by any other solution. These solutions constitute the first layer. Assuming that solutions A, B, and C are not dominated by any other solution, they belong to the first layer of non-dominated solutions. The second layer of non-dominated solutions, remove the population after the first layer, compare again, find the solution that is not dominated by any other solution, and form the second layer. Assume that solution D and solution E belong to the second layer. Subsequent layers: continue the previous step until all solutions are assigned to a certain layer.

[0028] Genetic Evolution of Non-Dominated Sorting Genetic Algorithm II

[0029] Once the non-dominated sorting is completed, these sorting layers can be used to perform selection, crossover and mutation operations to generate the next generation of populations. The lower the number of layers, the higher their priority, which means that these solutions are better balanced in multi-objective optimization; selection, crossover and mutation: use the selection, crossover and mutation operations in the genetic algorithm to generate a new population to ensure population diversity and accelerate the optimization process. Iterative solution: through multiple iterations, new populations are continuously generated and selected, gradually approaching the optimal solution. Each generation includes - calculation of fitness function, non-dominated sorting and crowding distance calculation, selection, crossover and mutation operations. The final optimization result is a Pareto frontier containing a set of non-inferior solutions.

[0030] The causes of the technical problems solved by the intelligent warehousing in the embodiment of the present application and the corresponding technical means and principles are explained as follows:

[0031] The reason for the recycling and reuse of power batteries is that retired power batteries can be used in energy storage facilities in the power system as energy storage devices for renewable energy to improve energy efficiency; retired power batteries can also be used to build power frequency regulation and backup power systems to provide auxiliary services for the power grid. By using intelligent storage systems, retired batteries can be tested and reclassified, and batteries that meet the standards can be reorganized, distributed, and then reused, thereby creating new economic value.

[0032] In the prior art, since retired power batteries of different brands have special battery management systems (BMS), the battery status is monitored and managed through their respective BMSs, for example, one or more of the following internal characteristic parameters: voltage, temperature, charge and discharge, and battery balancing. Since the BMS of retired power batteries of each brand is different and the corresponding authorization permissions are different, it is not feasible to obtain all battery information of retired power batteries of different brands. For example, for power batteries of brand A, due to permission issues, after the power batteries are retired, their corresponding battery balancing parameters and charge and discharge parameters cannot be collected or obtained, and some internal characteristic parameters of power batteries of brand A are not available. At this time, it costs a huge cost to obtain all the battery information of the complete retired power batteries, which is not advisable for enterprises that use and recycle power batteries in a gradient manner. Therefore, the problem of inability to effectively sort retired power batteries arises, which is the technical problem that needs to be solved by the embodiments of the present application.

[0033] For the technical problem to be solved by the embodiment of the present application, the means adopted by the embodiment of the present application is: by proposing to use the available external characteristic parameter data (that is, a large amount of external characteristic data of power battery consistency indicators obtained according to the retired power battery trading platform data, the battery popularity in the network and the measurable structured data, such as: battery name, battery type, battery supply quantity parameters) combined with some measurable internal characteristic parameters (for some measurable data of the disassembled battery, such as: residual capacity, voltage, current), the retired power batteries are managed, and the retired power batteries are sorted according to the above external characteristic parameters and internal characteristic parameters. That is, when some internal characteristic parameters of the retired power battery are not available or missing, the external characteristic parameters that can characterize the relevant characteristics of the retired power battery obtained based on the existing data are used to replace some of the unavailable internal characteristic parameters. The combination of the two jointly characterizes the consistency of the power battery to be reassembled, and then the retired power batteries are effectively sorted, so that the reassembled batteries can be used in energy storage scenarios in a timely manner, thereby improving the utilization rate of the retired power batteries.

[0034] The specific embodiments of the present application are described below:

[0035] The method embodiment provided in this embodiment can be executed in a terminal, a computer or a similar computing device. Taking running on a terminal as an example, Figure 1 : is a hardware structure block diagram of a terminal of the retired power battery intelligent storage method of the embodiment of the present application. Figure 1 As shown, the terminal may include one or more ( Figure 1Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data. Optionally, the terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is for illustration only and does not limit the structure of the above terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0036] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the intelligent storage method for retired power batteries in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0037] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0038] This embodiment provides a method for intelligent storage of retired power batteries running on the above terminal. Figure 2 is a flow chart of a method for intelligent storage of retired power batteries according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps:

[0039] Step S201, obtaining target information of multiple target power storage batteries AEVB to be stored, wherein each target information includes multiple target index parameters, and the target index parameter is used to characterize a characteristic parameter of the corresponding target AEVB, and the characteristic parameter includes an internal characteristic parameter and an external characteristic parameter.

[0040] In this embodiment, in order to sort the target AEVB (corresponding to retired power batteries), it is necessary to use the internal characteristic parameters and external characteristic parameters corresponding to the AEVB. After receiving the target AEVB to be stored, the measurable internal characteristic parameters in the target information can be measured and collected after the power battery is retired, or can be measured and collected in real time after the target AEVB is acquired. In this embodiment, the measurable internal characteristic parameters include voltage, temperature, and remaining capacity, and the internal characteristics are necessary parameters; and for the corresponding external characteristic parameters (for example, battery brand, generation date), it means that after the power battery is retired and determined to be used for reorganization, the more important (for example, the indicator parameters are sorted, and the indicator parameters ranked first) indicator parameters are selected from the preset indicator parameters (related to the external characteristic parameters) and assigned to the corresponding target AEVB. That is, after receiving the target AEVB to be stored, the target indicator parameters related to the external characteristic parameters in the target information of each target AEVB already exist.

[0041] Step S202, after preprocessing the various target indicator parameters corresponding to each target AEVB and generating the corresponding various standard feature parameters, the various standard feature parameters corresponding to each target AEVB are processed using the trained evaluation classification model to obtain classification label data corresponding to each target AEVB, wherein the classification label data includes a target recombination heat classification and a target recombination heat score value corresponding to the target AEVB, the target recombination heat classification is used to characterize the priority of the target AEVB when being recombined, and the evaluation classification model is a machine learning model trained based on the extreme gradient boosting decision tree algorithm XGBoost, and is trained to generate classification label data corresponding to the corresponding battery according to the input recombination battery characteristic parameters.

[0042] In this embodiment, before inputting a plurality of target indicator parameters into a trained evaluation classification model, the plurality of target indicator parameters need to be preprocessed first, that is, the plurality of target indicator parameters are processed into a data format recognizable by the evaluation classification model, and the evaluation classification model is trained using a sample data set of the corresponding data format; in this embodiment, after the preprocessing conversion generates corresponding standard feature parameters, the plurality of standard feature parameters are input into the evaluation classification model, and the plurality of standard feature parameters corresponding to each target AEVB are sorted, and then the important standard feature parameters are selected based on the sorting to perform AEVB classification and AEVB demand forecasting, wherein AEVB classification refers to dividing the AEVB to be stored into battery classifications for whether they are better reorganized, that is, whether the corresponding AEVB will be used for reorganization first; AEVB demand forecasting refers to evaluating the AEVB to be stored, and determining whether the AEVB is a recombinant battery product required in the future according to the evaluation results (corresponding score values), for example: when the score values ​​of the corresponding two AEVBs are 8.555 and 9.122 respectively, at this time, the probability that the AEVB with a high score value will be used as a recombinant battery product in the future is greater than that of the AEVB with a low score value.

[0043] In this embodiment, the evaluation and classification model of machine learning is used to sort the consistency indicators, classify the AEVB, and predict the AEVB demand. Then, the corresponding indicators and corresponding weights are determined at different nodes to obtain the target reorganization heat classification and the target reorganization heat score. The corresponding target reorganization heat classification is used to determine the approximate storage area of ​​the AEVB to be stored (that is, it indicates roughly which area), and the target reorganization heat score is used for the specific storage area of ​​the AEVB to be stored. In this embodiment, the actual space of the warehouse is divided into several independent areas, which can be allocated according to the heat level (corresponding to the consistent reorganization heat classification), for example: high heat (extremely hot, hot) storage area The storage area with high heat is set at the core position of the warehouse or the area with easy access. The high-heat storage area has a better environmental control system (for example: temperature and humidity control) and higher safety standards; the medium-heat (warm) storage area is allocated to the secondary central area. The regional environmental control and safety measures of the medium-heat storage area are medium, which is suitable for storing batteries with moderate access frequency; the low-heat (cool, cold) storage area is allocated to the edge of the warehouse or the area that is not frequently visited. The environmental control and safety measures of the low-heat storage area are relatively low. In this way, the reorganization heat classification and the target reorganization heat score can be used to reasonably layout the AEVB battery recycling storage to ensure the safety and efficiency of battery storage.

[0044] In this embodiment, the target reorganization heat classification and the target reorganization heat score are the expected targets of the corresponding target AEVB when allocating them to the storage area, that is, the most ideal storage location of the target AEVB to be stored at present. For example, the storage areas with high reorganization heat classification (corresponding heat score range of 8.000-10.000) are storage area 1, storage area 2, storage area 3, storage area 4 and storage area 5, and the corresponding reorganization heat score values ​​are 8.25, 8.5, 8.75, 9.0, 9.5 respectively; and one target AEVB corresponds to If the target recombinant heat classification in the classification label data is high heat and the target recombinant heat score value is 8.5, then the target storage area corresponding to the target AEVB is storage area 2; in the storage allocation planning process, the target recombinant heat classification and the target recombinant heat score value in the classification label data are used to guide the storage area allocated to the target AEVB from the initial randomly allocated storage area to the corresponding target storage area gradually, until it is allocated to the target storage area whose corresponding recombinant heat classification and recombinant heat score value correspond to the target recombinant heat classification and target recombinant heat score value respectively.

[0045] Step S203, based on the layout parameter information corresponding to the preset storage area and multiple target AEVBs, a multi-objective genetic NSGA-II algorithm is used to perform storage allocation planning to generate corresponding initial storage allocation information, wherein the initial storage allocation information includes the alternative storage area allocated to each target AEVB.

[0046] In this embodiment, after determining the classification label data corresponding to the target AEVB, storage allocation planning is performed according to the layout parameter information of the current warehouse area, that is, the corresponding optimal storage allocation is solved using the NSGA-II algorithm; in the solution process, the population is first randomly initialized, that is, a storage allocation plan is randomly generated, and the individuals in the randomly initialized population (corresponding to the initial storage allocation information) represent a consistent possible AEVB storage area configuration plan, that is, an alternative storage area allocated to each target AEVB, and the alternative storage area is a currently idle one in the preset storage area; it can be understood that the initial storage allocation information is a randomly initialized generated plan, and the corresponding storage fitness is likely to be greatly deviated from the target storage fitness. Therefore, it is necessary to perform non-dominated sorting iteration and genetic evolution operation iteration based on the NSGA-II algorithm on the initial storage allocation information.

[0047] Step S204, determine the first storage fitness corresponding to all the alternative storage areas in the initial storage allocation information, and according to the difference between the target storage fitness corresponding to the target recombination heat classification and the target recombination heat score value and the first storage fitness, perform non-dominated sorting iteration and genetic evolution operation iteration based on the NSGA-II algorithm on the initial storage allocation information until the difference is no more than a preset threshold, and generate the corresponding target storage allocation information, wherein the target storage allocation information includes the target storage area assigned to each target AEVB.

[0048] In this embodiment, a fitness function is used to measure the quality of individuals (corresponding to a storage area assigned to a target AEVB) corresponding to the storage allocation information generated during the storage allocation planning process, that is, by calculating the first storage fitness of the corresponding storage area in the storage allocation information solved based on the NSGA-II algorithm, the quality of the storage area allocation scheme solved at the time is measured, and by comparing the first storage fitness corresponding to the storage area assigned to all the target AEVBs at the time with the target storage fitness corresponding to the corresponding target AEVB, the storage allocation information generated at the time is guided to perform non-dominated sorting iterations and genetic evolution operation iterations based on the NSGA-II algorithm until the target storage allocation information is generated; it can be understood that in the process of performing non-dominated sorting iterations and genetic evolution operation iterations, the target recombination heat classification and target recombination heat score value in the classification label data are used to guide the storage area assigned to the corresponding target AEVB to gradually move closer to the corresponding target storage area until the corresponding recombination heat classification and recombination heat score value are respectively assigned to the target storage area corresponding to the target recombination heat classification and target recombination heat score value.

[0049] It should be noted that in this embodiment, the steps of non-dominated sorting and corresponding genetic evolution operations are corresponding operations in the relevant technology. Those skilled in the art can understand the steps of non-dominated sorting and corresponding genetic evolution operations, and they do not constitute unclear limitations on the present application.

[0050] Through the above steps S201 to S204, target information of multiple target power storage batteries AEVB to be stored is obtained, each target information includes multiple target indicator parameters, and the target indicator parameters are used to characterize a characteristic parameter of the corresponding target AEVB, and the characteristic parameters include internal characteristic parameters and external characteristic parameters; after preprocessing the multiple target indicator parameters corresponding to each target AEVB to generate the corresponding multiple standard characteristic parameters, the multiple standard characteristic parameters corresponding to each target AEVB are processed by using the trained evaluation classification model to obtain classification label data corresponding to each target AEVB, and the classification label data includes the target reorganization heat classification and the target reorganization heat score value corresponding to the target AEVB, and the target reorganization heat classification is used to characterize the priority of the target AEVB used during reorganization; based on the layout parameter information corresponding to the preset storage area and the multiple target AEVB, the multi-objective genetic NSGA-II algorithm is used to perform storage allocation planning to generate the corresponding initial storage allocation information, and the initial storage allocation information includes the alternative storage area allocated to each target AEVB; determine the location of all the alternative storage areas in the initial storage allocation information The corresponding first storage fitness is obtained, and according to the difference between the target storage fitness corresponding to the target recombination heat classification and the target recombination heat score and the first storage fitness, the initial storage allocation information is iterated by non-dominated sorting iteration and genetic evolution operation iteration based on the NSGA-II algorithm until the difference is no more than the preset threshold, and the corresponding target storage allocation information is generated, and the target storage allocation information includes the target storage area allocated to each target AEVB; the problem that retired power batteries cannot be effectively sorted during the storage process, the recycling rate of power batteries is reduced, and the intelligent storage effect is reduced in the related technology is solved, and the retired power batteries are managed and sorted by combining the obtainable external characteristic parameter data with some measurable internal characteristic parameters, so as to realize intelligent power battery storage and management, and can determine the reorganization consistency index and storage rules of retired power batteries according to different scenarios when some internal characteristic data are missing, effectively classify the incoming batteries, so that the reorganized batteries can be used in the energy storage scenario in time, thereby improving the utilization rate of retired power batteries, and reasonably plan and arrange the storage locations of the batteries in stock according to the storage location optimization rules, so that they meet certain safety and storage efficiency.

[0051] In some embodiments, preprocessing is performed on a plurality of target indicator parameters corresponding to each target AEVB to generate a plurality of corresponding standard feature parameters, which is achieved by the following steps:

[0052] Step 21 : extracting a plurality of target indicator parameters corresponding to each target AEVB from the target information of each target AEVB, wherein the target indicator parameter includes one of the following: AEVB type, AEVB brand, AEVB type, and AEVB electrical parameter.

[0053] In this embodiment, the target indicator parameters corresponding to the external characteristic parameters (for example: AEVB type, AEVB brand, AEVB type) refer to that after the power battery is retired and determined to be used for reorganization, more important indicator parameters are screened out from the preset indicator parameters and assigned to the corresponding target AEVB. When the target AEVB to be stored is received, the target information of each target AEVB already has the target indicator parameters corresponding to the external characteristic parameters; and the target indicator parameters characterizing the internal characteristic parameters can be measured when the power battery is retired as a target AEVB, or can be measured when it is stored in the warehouse.

[0054] Step 22, filtering, denoising and cleaning the target indicator parameters corresponding to all target AEVBs to generate standard indicator parameters.

[0055] In this embodiment, the target indicator parameters are filtered, that is, deduplication processing is performed to remove repeated items in the target indicator parameters to ensure that each data is unique, and then the format is converted to standardize different units of measurement, for example: the working voltage is uniformly converted into volts (V), and the battery capacity is uniformly converted into kilowatt-hours (kWh); the target indicator parameters are denoised, which means detecting abnormal values, detecting and eliminating obviously abnormal data points, for example: the power supply of the target AEVB is obviously too high or too low, and for example: the missing values ​​in the target indicator parameters are uniformly processed by filling the missing values ​​or eliminating data rows with seriously incomplete information; the target indicator parameters are cleaned, including: the target indicator parameters are formatted in a unified manner to ensure that all text fields are normalized, and redundant information is removed to retain core data.

[0056] Step 23, normalize the standard index parameters corresponding to all target AEVBs to generate standard feature parameters.

[0057] In this embodiment, the standard indicator parameters are normalized so that all standard feature parameters input into the evaluation classification model are at the same level.

[0058] Through the above steps, a variety of target indicator parameters corresponding to each target AEVB are extracted from the target information of each target AEVB, wherein the target indicator parameters include one of the following: AEVB type, AEVB brand, AEVB type, AEVB electrical parameters; the target indicator parameters corresponding to all target AEVBs are filtered, denoised and cleaned to generate standard indicator parameters; the standard indicator parameters corresponding to all target AEVBs are normalized to generate standard feature parameters, thereby preprocessing the target indicator parameters in the target information of all target AEVBs, so that the formed standard feature parameters have high quality, high consistency and analyzability, so as to evaluate the classification model for AEVB classification and demand forecasting.

[0059] In some of the embodiments, before obtaining target information of a plurality of target power storage batteries AEVB to be stored, the following steps are further implemented:

[0060] Step 31 uses a preset data collector to obtain corresponding hypertext markup language HTML page data from the target network platform.

[0061] In this embodiment, before collecting data, the target network platform is also identified to identify the network platform for trading retired power batteries; then, different data collectors (for example: Python's BeautifulSoup and Scrapy) are configured for different network platforms, and the data collectors regularly and automatically access the target network platform to obtain dynamic data and extract HTML page data.

[0062] Step 32, extracting the transaction data corresponding to the AEVB from the HTML page data, and parsing the first indicator parameter corresponding to the external characteristic parameter from the transaction data.

[0063] In this embodiment, the transaction data corresponding to the AEVB is extracted by parsing the HTML page data. The corresponding transaction data includes the AEVB name, brand, AEVB type, supply quantity, application scenario, and power supply. Among them, the AEVB names include automotive batteries, industrial batteries, and energy storage batteries. The brand refers to the corresponding battery supplier; the AEVB types include battery packs (Pack), modules (Module), and cells (Cell); the supply quantity provides batch quantity, total quantity, units such as kWh or number of groups and other data; the application scenario refers to the corresponding usage scenario description, for example: electric vehicles, power tools, energy storage systems; the power supply includes voltage (V) and capacity (Ah or kWh).

[0064] Step 33: Use the second indicator parameter and the first indicator parameter corresponding to the collected intrinsic characteristic parameters as target indicator parameters.

[0065] In this embodiment, after the first indicator parameter is obtained, the first indicator parameter is used as an indicator parameter library. When an AEVB is retired and used for reorganization, the corresponding first indicator parameter is selected from the parameter library and assigned to the corresponding AEVB, so that the target information of the AEVB has target indicator parameters representing external characteristic parameters. At the same time, some internal characteristic parameters can be obtained through measurement, and then the second indicator parameters corresponding to the measured internal characteristic parameters are associated with the AEVB, so that the target information of the AEVB has complete target indicator parameters. It should be understood that using the second indicator parameter and the first indicator parameter as target indicator parameters refers to a parameter library corresponding to the corresponding target indicator parameters, and the target indicator parameters associated with a specific AEVB need to be generated or obtained by assigning the corresponding first indicator parameter and measuring the second indicator parameter.

[0066] By utilizing the preset data collector in the above steps, the corresponding hypertext markup language HTML page data is obtained from the target network platform; the transaction data corresponding to the AEVB is extracted from the HTML page data, and the first indicator parameter corresponding to the external characteristic parameter is parsed from the transaction data; the second indicator parameter and the first indicator parameter corresponding to the collected internal characteristic parameter are used as the target indicator parameter, thereby realizing the construction and preset of the target indicator parameter, and then the target indicator parameter of the retired AEVB as the recombinant battery can be quickly determined, and then the target AEVB can be quickly sorted and stored.

[0067] In some of the embodiments, based on the layout parameter information corresponding to the preset storage area and multiple target AEVBs, a multi-objective genetic NSGA-II algorithm is used to perform storage allocation planning and generate corresponding initial storage allocation information, which is achieved through the following steps:

[0068] Step 41, obtain the coding information corresponding to multiple target AEVBs and the layout parameter information of each storage area, wherein the layout parameter information includes the reorganization picking efficiency parameters, storage safety parameters and storage status parameters corresponding to each storage area, the reorganization picking efficiency parameters are determined based on the location information of the storage area, and the storage safety parameters are determined based on the storage environment and location information corresponding to the storage area.

[0069] Step 42, after determining the currently idle storage area according to the storage status parameters, randomly assign codes to the currently idle storage area and each coding information to obtain multiple coding bodies corresponding to multiple target AEVBs, and use the storage area corresponding to each coding body as the corresponding candidate storage area.

[0070] Step 43, determine the first storage fitness corresponding to each alternative storage area, and generate initial storage allocation information based on the alternative storage areas and the first storage fitness corresponding to all target AEVBs, wherein the first storage fitness is generated by weighting the reorganization picking efficiency parameters and storage safety parameters corresponding to the corresponding storage areas.

[0071] In this embodiment, the degree of superiority of each storage allocation scheme is determined based on the two indicators of reorganization picking efficiency and storage safety parameters, that is, the first storage fitness corresponding to the alternative storage area allocated to each target AEVB is calculated to measure the excellence of the allocation scheme, wherein the reorganization picking efficiency is calculated based on the storage record data, the picking path length and time corresponding to each storage area, and then the corresponding reorganization picking efficiency is calculated; the reorganization safety parameter is based on the storage environment and location of the corresponding storage area. The heat classification and corresponding safety score, for example: the storage area equipped with an environmental control system and safety protection measures has a high corresponding safety score.

[0072] Through the above steps 41 to 43, a random generation of a storage allocation plan is achieved, providing data for determining target storage allocation information.

[0073] In some embodiments, according to the difference between the target storage fitness and the first storage fitness corresponding to the target recombination heat classification and the target recombination heat score value, the initial storage allocation information is subjected to non-dominated sorting iteration and genetic evolution operation iteration based on the NSGA-II algorithm, including the following steps:

[0074] Step 51, determine the fitness interval corresponding to the target reorganization heat classification corresponding to each target AEVB, and determine whether the first storage fitness corresponding to each candidate storage area is in the corresponding fitness interval.

[0075] Step 52, when it is determined that the first storage fitness corresponding to at least one alternative storage area is not in the fitness interval, the initial storage allocation information is subjected to multiple non-dominated sorting iterations and genetic evolution operation iterations based on the NSGA-II algorithm, until the first storage fitness corresponding to the current storage area allocated to each target AEVB in the generated current storage allocation information is in the corresponding fitness interval, wherein the genetic evolution operation includes a coding body selection operation, a coding body crossover operation and a coding body mutation operation.

[0076] Step 53, determine whether the difference between the first storage fitness corresponding to the current storage area and the target storage fitness corresponding to the target reorganization heat score is greater than a preset threshold. When it is determined that the difference between the first storage fitness corresponding to the current storage area and the target storage fitness is not greater than the preset threshold, the current storage area is used as the target storage area corresponding to the target AEVB, and the target storage allocation information is generated.

[0077] Step 54, when it is determined that the difference between the first storage fitness corresponding to the current storage area and the target storage fitness corresponding to the target reorganization heat score value is greater than a preset threshold, the current storage allocation information is iterated by non-dominated sorting and genetic evolution operations based on the NSGA-II algorithm.

[0078] In some of the embodiments, before the first storage fitness corresponding to at least one current storage area is in the corresponding fitness interval, the following steps are also implemented: repeatedly executing non-dominated sorting iterations and genetic evolution operation iterations based on the NSGA-II algorithm on the storage allocation information generated this time.

[0079] In some embodiments, evaluating the training of the classification model includes:

[0080] Step 61, obtaining a preset data set, wherein the data set includes target indicator parameters corresponding to a plurality of AEVBs.

[0081] Step 62, after preprocessing the target indicator parameters corresponding to each AEVB in the data set to generate a feature parameter set, all standard feature parameters corresponding to each AEVB in the feature parameter set are divided into recombinant battery feature groups, and the recombinant battery feature groups corresponding to each AEVB are annotated with corresponding classification label data to generate a recombinant battery feature parameter set.

[0082] Step 63, cutting the recombinant battery characteristic parameter set into a recombinant battery characteristic parameter training set and a recombinant battery characteristic parameter test set according to a preset ratio, and using the recombinant battery characteristic parameter training set to train the initially constructed XGBoost machine learning model until regression fitting is achieved to obtain a trained XGBoost machine learning model.

[0083] In this embodiment, the XGBoost machine learning model is initially constructed, the relevant parameters and objective function of the XGBoost model are configured, and all standard feature parameters in the recombinant battery feature parameter training set are used as input, and the corresponding classification label data is used as supervision for training; the optimal parameters are selected by setting parameters such as the number of trees, depth, and learning rate, and performing cross-validation.

[0084] Step 64, using the recombinant battery characteristic parameter test set, the trained XGBoost machine learning model is tested and evaluated to train and generate an evaluation classification model.

[0085] In this embodiment, when the recombinant battery characteristic parameter test set is used to evaluate the model, all standard characteristic parameters in the recombinant battery characteristic parameter test set are used as input, and the deviation between the classification label data output by the model and the classification label data annotated for the recombinant battery characteristic parameter test set is compared, thereby evaluating the effect of the evaluation classification model; in this embodiment, the evaluation classification model effect is evaluated by using indicators such as accuracy, precision, recall rate, and F1-score.
