Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0053] Example 1

[0054] The purpose of the embodiments of this application is to provide a power battery raw material data management method based on blockchain technology, which can achieve full life cycle management of power battery raw materials from mining, processing, transportation, use to recycling, and ensure the authenticity, integrity, credibility, security, interoperability and efficiency of power battery raw material data to meet the legal and regulatory requirements of countries and regions such as the European Union. The embodiments of this application also use blockchain technology combined with data analysis to evaluate and analyze power battery raw material data and stored evidence information, obtain corresponding analysis reports and certification documents, and improve the efficiency of power battery raw material evaluation and analysis.

[0055] The present application provides a method for managing raw material data of a power battery. In a first embodiment of the method for managing raw material data of a power battery of the present application, referring to FIG1 , the method for managing raw material data of a power battery includes:

[0056] Step S10, writing the collected power battery raw material data into the blockchain network;

[0057] Step S20: Evaluate the power battery raw material data in the blockchain network according to preset power battery raw material rules, and generate an analysis report corresponding to the power battery raw material data;

[0058] Step S30: generating a certification document corresponding to the power battery raw material data based on the evidence information of the power battery raw material data in the blockchain network;

[0059] Step S40: In response to the user's query request, the target data corresponding to the query request in the blockchain network is displayed to the user, wherein the target data includes at least one of the power battery raw material data, the analysis report, or the certification document.

[0060] In the embodiments of the present application, it should be noted that the power battery raw material data includes relevant data of various types of raw materials used as power batteries, including attribute data of the raw materials themselves, such as location, temperature, weight, voltage and current, etc., as well as the corresponding flow data of the raw materials during the circulation process, including the participants involved in the circulation process of the power battery raw materials, for example, the participants include mines, smelters, material producers, battery manufacturers, logistics companies, automobile manufacturers and recycling companies, etc. The blockchain network is composed of multiple nodes, each of which stores the same data and consensus mechanism. After being written into the blockchain network, the power battery raw material data can be evaluated according to the preset power battery raw material rules, wherein the power battery raw material rules are various laws and regulations, procurement standards and qualification requirements for participants input as needed, etc., which are used to evaluate the data of each dimension of the power battery raw materials separately to generate an analysis report corresponding to the power battery raw material data to achieve a detailed analysis of the various raw materials of the power battery. The certification documents specifically include the corresponding evidence information generated by each participant when uploading power battery raw material data to the blockchain network. This information can include identity information, time information, and signature information, used to characterize the source and credibility of the power battery raw material data in the blockchain network. Furthermore, users can enter query requests through a pre-set user interface. The query requests can query one or more items from the power battery raw material data, analysis reports, and certification documents, and present them to the user in a visual manner.

[0061] The embodiments of the present application use blockchain technology to achieve the decentralization, non-tamperability, traceability, and verifiability of power battery raw material data, thereby ensuring the authenticity, integrity, credibility, and security of power battery raw material data.

[0062] As an example, steps S10 to S40 include: collecting attribute data of power battery raw materials in each link through an Internet of Things device, and obtaining the flow data of power battery raw materials input by the user through a preset user interface to obtain power battery raw material data; encrypting the power battery raw material data, and uploading the encrypted power battery raw material data to the blockchain network node; verifying the uploaded encrypted power battery raw material data through the consensus mechanism in the blockchain network node, and if passed, writing the encrypted power battery raw material data into the blockchain network; evaluating the power battery raw material data according to the power battery raw material rules pre-written in the blockchain network to obtain an analysis report corresponding to the power battery raw material data; generating a certification document corresponding to the power battery raw material data based on the corresponding existence information of each participant when uploading the power battery raw material data to the blockchain network; when a query request initiated by the user is received, querying the target data corresponding to the query request in the blockchain network, wherein the target data at least includes one or more of the power battery raw material data, the analysis report or the certification document.

[0063] Further, referring to FIG2 , the step of evaluating the power battery raw material data in the blockchain network according to the preset power battery raw material rules and generating an analysis report corresponding to the power battery raw material data includes:

[0064] Step S21, obtaining preset power battery raw material rules, wherein the power battery raw material rules at least include evaluation criteria corresponding to various power battery raw material types;

[0065] Step S22, evaluating data of each dimension in the power battery raw material data according to an evaluation standard corresponding to the raw material type of the power battery raw material data, to obtain an evaluation result of the data of each dimension in the power battery raw material data;

[0066] Step S23 : generating an analysis report corresponding to the power battery raw material data based on the evaluation results of the data of each dimension in the power battery raw material data.

[0067] In the embodiment of the present application, it should be noted that the power battery raw material rules may include various laws and regulations on power battery raw materials, and may also include procurement standards for power battery raw materials, and may also include the qualifications of each participant in the power battery raw materials and business logic and rules required by other industries in the traceability process of power battery raw materials. The embodiment of the present application can realize the automation, standardization, and normalization of the above business logic and rules through smart contract technology, thereby improving the interoperability and efficiency of power battery raw material data. The power battery raw material rules are mainly used to evaluate and assess each dimension of the power battery raw material data and generate corresponding analysis reports for reference by regulatory agencies and consumers, thereby improving the trust and transparency of power battery raw material data to consumers and regulatory agencies, and can also be used as a reference for participants to avoid potential legal risks. Specifically, the analysis report includes the evaluation results of each dimension of the power battery raw material data and the comprehensive evaluation results. The evaluation results can be the evaluation level, evaluation score, or pass status of each data under the evaluation criteria, and the comprehensive evaluation results can be the comprehensive evaluation level or evaluation score of each data of the power battery raw material according to the preset standards.

[0068] It should be noted that there is no fixed order between step S21-step S22 and step S23. They can be performed in the order of step S21-step S22-step S23, or in the process of step S23-step S21-step S22, or step S21-step S22 and step S23 can be performed simultaneously. The embodiment of the present application realizes the in-depth analysis, legality assessment, report generation and other features of power battery raw material data through the power battery raw material rules stored in each node of the blockchain, thereby improving the visualization and provability of power battery raw material data.

[0069] As an example, steps S21 to S23 include: obtaining pre-input power battery raw material rules, wherein the power battery raw material rules include at least evaluation criteria corresponding to various types of raw materials of power batteries; evaluating each dimension of the power battery raw material data according to the evaluation criteria of each dimension of the raw material type corresponding to the power battery raw material data, and obtaining the evaluation level, evaluation score or pass status of each dimension of the power battery raw material data, wherein the raw material type may include rare metals such as cobalt, lithium, nickel, manganese or other non-metallic materials such as graphite, and each dimension of the data may include the position corresponding to the power battery raw material, Attribute data such as temperature, weight, voltage and current may also include detailed flow data of various participants such as mines, smelters, material manufacturers, battery manufacturers, logistics companies, automobile manufacturers and recycling companies; the power battery raw material data is comprehensively evaluated according to the evaluation level, evaluation score or pass status of the data of each dimension in the power battery raw material data to obtain the comprehensive evaluation level or evaluation score of the power battery raw material data; the evaluation level, evaluation score or pass status of the data of each dimension in the power battery raw material data and the comprehensive evaluation level or evaluation score of the power battery raw material data are aggregated to obtain an analysis report corresponding to the power battery raw material data.

[0070] In addition, the power battery raw material data includes at least attribute data and flow data. Before the step of writing the collected power battery raw material data into the blockchain network, referring to FIG3 , the method further includes:

[0071] Step A10: collecting attribute data of power battery raw materials during the mining, processing, transportation, use, and recycling of power battery raw materials through IoT devices, wherein the attribute data includes at least one of location, temperature, weight, voltage, and current;

[0072] Step A20: Acquire flow data input by the user, wherein the flow data includes participants involved in the flow of power battery raw materials, and the participants include at least one of a mine, a smelter, a logistics company, an automobile manufacturer, and a recycling company;

[0073] Step A30: encrypt the collected power battery raw material data to obtain encrypted power battery raw material data.

[0074] In the embodiment of the present application, it should be noted that step A10 and step A20 can be performed simultaneously, and step A30 is performed after the data collection of all power battery raw materials is completed. The embodiment of the present application collects data of various dimensions of power battery raw materials in two ways. Relevant data (such as location, temperature, weight, voltage, current, etc.) can be collected from the mining, processing, transportation, use and recycling of power battery raw materials through Internet of Things devices (such as sensors, RFID (Radio Frequency Identification) technology, GPS (Global Positioning System), etc.). It can also be collected from various participants in the power battery raw materials (such as mines, smelters, material manufacturers, battery manufacturers, logistics companies, automobile manufacturers, recycling companies, etc.) through manual input (such as scanning QR codes, filling out forms, importing, etc.) Relevant data (such as identity information, contract information, certificate information, etc.) can be collected. Finally, in order to ensure that the data is not tampered with or leaked during transmission, the collected data needs to be encrypted.

[0075] Since the traceability of power battery raw materials requires the collection, analysis, verification, and review of a large amount of power battery raw material data, if traditional manual or semi-automated methods are used to process the data, it may cause problems such as low data processing efficiency, high costs, and poor timeliness. Therefore, the embodiment of the present application improves the efficiency and accuracy of data collection through the above-mentioned data collection method, and further improves the timeliness of data through the blockchain network. In addition, since the traceability of power battery raw materials involves sensitive information such as commercial secrets and personal privacy, if traditional centralized databases or cloud platforms are used to store data, there may be risks such as data leakage, hacker attacks, and malicious tampering. The embodiment of the present application overcomes the above-mentioned technical defects through the above-mentioned method and improves the security of power battery raw material data.

[0076] As an example, steps A10 to A30: collect attribute data such as location, temperature, weight, voltage, current, etc. in the entire life cycle of power battery raw materials through sensors, RFID, GPS and other technologies; obtain the identity information, contract information, certificate information and other flow data of all participants in the entire life cycle of power battery raw materials collected by staff through scanning QR codes, filling out forms or importing; encrypt the collected attribute data and flow data according to a preset key to obtain corresponding encrypted power battery raw material data, so as to complete the encryption of the attribute data and the flow data.

[0077] Furthermore, the step of writing the collected power battery raw material data into the blockchain network includes:

[0078] Step S11, performing a hash operation on the encrypted power battery raw material data to obtain a hash value;

[0079] Step S12: digitally sign the hash value according to a preset private key to obtain a digital signature value;

[0080] Step S13: sending the encrypted power battery raw material data and the digital signature value to a blockchain network, and verifying the digital signature value according to a consensus mechanism in the blockchain network to obtain a verification result;

[0081] Step S14: If the verification result is passed, the encrypted power battery raw material data is written into the blockchain network.

[0082] In the embodiment of the present application, it should be noted that the embodiment of the present application first performs a hash operation on the encrypted power battery raw material data and performs a digital signature to obtain a corresponding digital signature value. The digital signature value is used for the consensus mechanism on the blockchain network to identify the identity of the data uploader, ensure the validity of the data, and prevent unrelated personnel from maliciously uploading data.

[0083] In another feasible embodiment, a manual review step can be added. When the digital signature value and the encrypted power battery raw material data are uploaded to the node of the blockchain network, manual review can be performed to determine whether they have passed the verification, thereby further improving the reliability of the data source.

[0084] As an example, steps S11 to S14 include: performing a hash operation on the encrypted power battery raw material data according to a preset hash algorithm to obtain a hash value corresponding to the encrypted power battery raw material data; encrypting the hash value according to a preset private key to obtain a digital signature value; uploading the encrypted power battery raw material data and the digital signature value to a node of the blockchain network; decrypting the digital signature value by using a public key preset in a consensus mechanism on the blockchain network node to obtain a second hash value; performing a hash operation on the encrypted power battery raw material data by using a hash algorithm preset in a consensus mechanism on the blockchain network node to obtain a third hash value; comparing the second hash value and the third hash value for consistency; if they are consistent, the verification result is passed, and the encrypted power battery raw material data is written into the blockchain network; if they are inconsistent, the verification result is failed.

[0085] In addition, in response to the user's query request, the step of displaying the target data corresponding to the query request in the blockchain network to the user includes:

[0086] Step S41: obtaining a query request input by a user through a preset user interface, wherein the query request includes at least one of a raw material batch number, a participant identity, and a time range;

[0087] Step S42, searching the blockchain network for target data corresponding to the query request;

[0088] Step S43: presenting the target data to the user in a visual manner, wherein the visual manner includes at least one of a table, a chart, and a map.

[0089] In this embodiment, it should be noted that the preset user interface can be a user interface on the system or platform corresponding to the blockchain network, or a user interface on other systems or platforms. Other systems or platforms can be connected to the blockchain network through standardized interfaces, so that users can initiate query requests in the user interfaces of more systems or platforms. Users can enter one or more information such as raw material batch number, participant identity, and time range in the user interface to query the target data stored in the blockchain network. The information corresponding to the query request entered by the user in the user interface can be set according to specific needs and is not limited here, so that users can query the required target data based on multi-dimensional request information. Specifically, the target data can include a combination of one or more of tables, charts, and maps. The table can include data of various dimensions of power battery raw materials. The chart includes a statistical chart made based on data of various dimensions of power battery raw materials, allowing users to browse the data of various dimensions of power battery raw materials more intuitively. The map is used to characterize the location information corresponding to the power battery raw materials in the entire life cycle.

[0090] As an example, steps S41 to S43 include: obtaining a query request input by a user through a preset user interface, wherein the query request may be composed of one or more of raw material batch number, participant identity, time range or other information, and the query request also includes one or more of original data, evaluation reports and certification documents, and the original data is the collected power battery raw material data; querying the nodes of the blockchain network for one or more of the encrypted power battery raw material data, the evaluation report corresponding to the power battery raw material data, and the corresponding certification documents that match the query request; if the query request includes power battery raw material data, it is first decrypted and then displayed; finally, the matched target data is displayed to the user in the user interface in a visual manner, wherein the visualization manner includes one or more of tables, charts and maps.

[0091] Furthermore, the step of retrieving target data corresponding to the query request in the blockchain network includes:

[0092] Step S421: If the query request includes power battery raw material data, then searching the blockchain network for the encrypted power battery raw material data corresponding to the query request;

[0093] Step S422, decrypting the encrypted power battery raw material data to obtain the power battery raw material data;

[0094] Step S423: If the query request includes an analysis report or certification document corresponding to the power battery raw material data, the analysis report or certification document corresponding to the query request is retrieved in the blockchain network.

[0095] In the embodiments of the present application, it should be noted that, in each node of the blockchain network, the encrypted power battery raw materials are stored in groups with the corresponding analysis reports and certification documents. Users can select one or more of the power battery raw materials, analysis reports, and certification documents according to the query request. Generally, when querying the target data in each node of the blockchain network according to the query request initiated by the user, the corresponding power battery raw material data is usually queried first, and then the corresponding analysis report or certification document is queried according to the demand. In addition, since the power battery raw material data is stored in an encrypted form in each node of the blockchain network, it needs to be decrypted first. The key used for decryption corresponds to the key used for encryption after the power battery raw material data is collected.

[0096] As an example, steps S421 to S423 include: if the query request includes power battery raw material data, then matching the corresponding encrypted power battery raw material data in the blockchain network according to the raw material batch number, participant identity, time range and other information in the query request; decrypting the matched encrypted power battery raw material data according to a preset key to obtain the decrypted power battery raw material data; if the query request includes an analysis report or certification document, then matching the qualified analysis report or certification document in the blockchain network according to the raw material batch number, participant identity and time range and other information in the query request.

[0097] An embodiment of the present application provides a method for managing power battery raw material data. The method comprises the following steps: first, writing collected power battery raw material data into a blockchain network; then, evaluating the power battery raw material data in the blockchain network according to preset power battery raw material rules, generating an analysis report corresponding to the power battery raw material data; and, based on the evidence information stored in the blockchain network, generating a certification document corresponding to the power battery raw material data; and finally, in response to a user's query request, displaying target data corresponding to the query request in the blockchain network to the user. The target data includes at least one of the power battery raw material data, the analysis report, or the certification document. The technical solution of the embodiment of the present application ensures the authenticity, integrity, credibility, and security of the power battery raw material data by utilizing the blockchain network to share the power battery raw material data, thereby reducing the difficulty of tracing the power battery raw materials. The method also combines blockchain technology with data analysis to evaluate and analyze the power battery raw material data and the evidence information, obtaining corresponding analysis reports and certification documents, thereby improving the efficiency of the evaluation and analysis of power battery raw materials. The method further enables users to query the required target files in the blockchain network as needed, thereby improving the interoperability and efficiency of power battery raw material data.

[0098] Example 2

[0099] Furthermore, based on the first embodiment of the present application, in another embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction and will not be repeated hereafter. On this basis, the power battery raw material data management method further includes:

[0100] Step B10: converting the data in the blockchain network into a form compatible with other systems or platforms, and transmitting the data in the blockchain network to other systems or platforms through a preset standardized data interface; and / or,

[0101] Step B20: Convert the data sent by other systems or platforms into a form compatible with the blockchain network through the standardized data interface.

[0102] In the embodiments of the present application, it should be noted that the traceability of power battery raw materials involves multiple different systems and platforms. There may be differences in data formats, standards, protocols, etc. between each system and platform, which makes it difficult to achieve data interconnection across systems, platforms, countries and regions.
