[0002] Currently, although the level of automation in power battery manufacturing has significantly improved, the level of information technology in production is still low, and the management level of the production process is relatively backward. For example, the production cycle of power batteries is relatively long, there are many production equipment, and the estimation of equipment capacity in different production sections is complex. The uneven production and lack of sharing of dynamic production information bring great difficulties to on-site management. Enterprises urgently need to take detailed and accurate measures such as production planning and scheduling, work scheduling, production tracking, on-site semi-finished product inventory management, and material management.

[0003] The production process of lithium-ion battery cells is quite complex, involving more than fifty steps from battery materials to battery capacity assessment. Since the material information, process parameters, and quality inspections for each step are different, the cell production process is divided into multiple segments. Each segment's processes correspond to various equipment information, and the production equipment for each process needs to collect parameters for the cell and verify whether the materials and process parameters are qualified.

[0066] Figure 1a This is a schematic flowchart of a lithium-ion battery cell production process control method according to Embodiment 1 of this application. Embodiment 1 includes the following steps:

[0067] S101. Obtain lithium-ion battery cell production work order information.

[0068] In this embodiment, the lithium-ion battery cell production work order information includes the priority of the lithium-ion battery cell production work order, the equipment information for lithium-ion battery cell production, the production line for lithium-ion battery cell production, the process information to be performed, batch information, and material information. The batch information includes processes such as in production, abnormal completion, and queued.

[0069] In this embodiment, the lithium-ion battery cell production work order information is differentiated into front-end execution and mid-to-back-end execution stages based on the different production characteristics of the front, mid, and back-end processes of lithium-ion battery cells, and corresponding interfaces are provided. The interface display format can be the same as that of a manufacturing execution system. Further details can be found in [reference needed]. Figure 1b A schematic diagram of a pre-process execution interface is shown. Figure 1c The diagram shows a schematic of the execution interface for a mid-to-late stage of the process.

[0070] S102. Based on the priority of lithium-ion battery cell production work order information, obtain the equipment information corresponding to the work order information.

[0071] In this embodiment, the corresponding equipment information is obtained according to the priority of the lithium-ion battery cell production work order information. Specifically, lithium-ion battery cell production work order information with higher priority is processed first, followed by lithium-ion battery cell production work order information with the second highest priority.

[0072] S103. Based on the equipment information, control the production process of the production equipment associated with the equipment information, and display the production process.

[0073] In this embodiment, different equipment information corresponds to different production processes. The production process executed by the equipment can be determined through the equipment information, and the production process is displayed on the interface of the manufacturing execution system.

[0074] This application provides a method for controlling the production process of lithium-ion battery cells. The method involves acquiring lithium-ion battery cell production work order information; obtaining equipment information corresponding to the work order information based on its priority; controlling the production process of the associated production equipment based on the equipment information; and displaying the production process. By displaying the production process of all equipment, the real-time production status of the cells can be observed on-site, allowing for timely handling of problematic cells in case of issues.

[0075] Figure 2 This is a schematic flowchart of a lithium-ion battery cell production process control method according to Embodiment 2 of this application. Embodiment 2 includes the following steps:

[0076] S201. Obtain lithium-ion battery cell production work order information.

[0077] The lithium-ion battery cell production work order information is divided into the front-stage execution stage and the middle-stage execution stage according to the different production characteristics of the front, middle and rear stages of the lithium-ion battery cell process.

[0078] For example, this step can refer to step S101 above, and will not be repeated here.

[0079] S202. Based on the priority of lithium-ion battery cell production work order information, obtain the equipment information corresponding to the work order information.

[0080] For example, this step can refer to step S102 above, and will not be repeated here.

[0081] S203. Based on the equipment information, obtain the material information associated with the equipment information.

[0082] In this embodiment, the Bill of Material (BOM) is a file that describes the product structure in a data format. It is a product structure data file that a computer can recognize and is also the leading file of ERP. The types of BOM in the ERP system mainly include five categories: indented BOM, summary BOM, reverse lookup BOM, cost BOM, and planning BOM.

[0083] S204. Adjust the material information according to the preset material information table to obtain the adjusted material information.

[0084] In this embodiment, the material loading process is carried out according to the process characteristics and the work order BOM information. The material loading will call the material loading verification interface information to verify whether this batch of materials can be loaded into this process. The remaining amount of materials loaded into the current equipment and the batch material consumption information can be viewed. The unloading operation can also be performed on the loaded materials. That is, the loading and unloading operations can be performed on the manufacturing execution system execution interface without calling the equipment interface.

[0085] S205. Based on the material production equipment, lithium-ion battery cells are produced according to the adjusted material information.

[0086] In this embodiment, lithium-ion battery cells are produced after the material production equipment updates and adjusts the material information.

[0087] S206. Based on the equipment information, obtain the process parameter information of the lithium-ion battery cells produced by the corresponding equipment.

[0088] In this embodiment, for lithium-ion battery cells that are in production, the cell completion operation can be performed on the execution interface, and the process parameter information of the end of this process can be entered. That is, there is no need to call the save history interface to save the process parameter information returned by the equipment. The lithium-ion battery cell can be completed when the equipment cannot save data of the cells in production or other situations.

[0089] S207. Adjust the process parameter information according to the preset process parameter information table to obtain the adjusted process parameter information.

[0090] In this embodiment, for the lithium-ion battery cells that have been manufactured, the equipment uploads process parameters and material depletion data. Based on the preset process parameter information table, it determines whether the lithium-ion battery cell has missing parameters or materials. The lithium-ion battery cell data is displayed on this interface. For the lithium-ion battery cell with missing parameters or materials, the parameters and consumption of the batch of lithium-ion battery cells can be supplemented.

[0091] S208. Production equipment based on process parameters, producing lithium-ion battery cells according to the adjusted process parameter information.

[0092] In this embodiment, the process parameter production equipment produces lithium-ion battery cells according to the adjusted process parameter information.

[0093] S209. If the lithium-ion battery cells corresponding to the equipment information are abnormal.

[0094] In this embodiment, NG entry is performed on cells in each production state. For the handling of abnormal products in QMS, NG entry can be performed on cells in the current process, and the NG information of the cells is synchronized to QMS. The flow of lithium-ion battery cells is controlled according to the judgment result.

[0095] S210: Control the corresponding equipment to handle abnormalities in lithium-ion battery cells.

[0096] In this embodiment, after the lithium-ion battery cells enter the production state upon arrival at the station, if an emergency disposal of lithium-ion battery cells is required before production is completed, an inspection and processing operation is performed. The manufacturing execution system executes a cancellation operation on the corresponding lithium-ion battery cell, and the field equipment discharges the lithium-ion battery cell into the NG tank. Depending on the on-site processing situation, the lithium-ion battery cell may be re-entered into the station or scrapped. Batch cancellation of lithium-ion battery cells is possible.

[0097] S211. If the lithium-ion battery cells produced by the equipment information need to be returned to the production line.

[0098] In this embodiment, after the lithium-ion battery cell production is completed, the equipment uploads parameter information. If the parameter information determines that the cell is NG (not good), the NG parameters have not been configured for rework. The lithium-ion battery cell can be reworked in the abnormal handling interface of the quality management system. This execution interface can also be used to re-enter the lithium-ion battery cell in this process. The lithium-ion battery cell enters the equipment for this process for production. Furthermore, lithium-ion battery cells can be re-entered in batches.

[0099] S212, Control the production equipment to restart the production of lithium-ion battery cells.

[0100] In this embodiment, after the lithium-ion battery cell production is completed, the next process is initiated to remove NG (Not Found) lithium-ion battery cells. For example, if an RKD (Recycled Knockout) cell results in an NG, it needs to be processed. This situation will damage the coating, requiring the cell to be re-coated. The cell needs to be modified to BMD (Browser Deposit) and re-coated. Executing the interface transfer operation can transfer this lithium-ion battery cell to the previous process or multiple previous processes for production. Production operations are executed according to the process route configuration under the lithium-ion battery cell production work order information, allowing for batch transfer of lithium-ion battery cells.

[0101] S213. Based on the equipment information, perform first and last component inspections on the lithium-ion battery cells associated with the equipment information, and obtain the first and last component inspection results.

[0102] In this embodiment, the quality management system performs first and last piece inspections on normally completed lithium-ion battery cells. The first piece collection function synchronizes information such as the lithium-ion battery cell work order number and materials, and pushes the lithium-ion battery cell inspection data to the quality management system for aggregation.

[0103] S214. Based on the test results of the first and last parts, produce lithium-ion battery cells.

[0104] In this embodiment, if the first and last parts are tested and found to be good, then lithium-ion battery cells are produced.

[0105] S215. Demonstrate the production process.

[0106] For example, this step can refer to step S103 above, and will not be repeated here.

[0107] This application provides a method for controlling the production process of lithium-ion battery cells. By controlling different production processes linked to control equipment information, such as material information, process parameters of the lithium-ion battery cells, and abnormal information of the lithium-ion battery cells, the method processes the lithium-ion battery cells. Using this technical solution, based on the actual situation of the lithium-ion battery cells produced in each process, operations such as transferring, re-injecting, and canceling lithium-ion battery cells can be performed. Furthermore, the method can synchronize equipment material consumption and predict whether replenishment is needed for continued production of lithium-ion battery cells.
