Abstract
A battery manufacturing method according to the present disclosure includes generating a virtual identifier (ID) corresponding to a battery cell, shifting the virtual ID according to a progression of processes included in a process line for the battery cell, storing the shifted virtual ID and associating the shifted virtual ID with process data generated for the battery cell, extracting a cell ID for the battery cell, and matching the process data associated with the shifted virtual ID with the cell ID, and transmitting the process data to an upper control system.
Claims17
A battery manufacturing method comprising:
- generating, by a process controller, a virtual identifier (ID) corresponding to a battery cell, wherein the process controller is configured to shift the virtual ID across performance of battery processing operations which comprises first to nth processes and a barcode process, n is a natural number of 2 or greater, included in a battery manufacturing process for the battery cell;
- performing, by battery cell processing equipment, a battery processing operation on the battery cell;
- generating, by the battery cell processing equipment, process data for the battery cell indicating a work result or a test result related to the battery cell;
- associating, by the process controller, the virtual ID with the process data generated for the battery cell;
- physically marking a cell ID on the battery cell when one of the first to nth processes is performed;
- extracting, by a cell ID collector, the cell ID of the battery cell during the barcode process after the first to nth processes are completed;
- generating process information, by the process controller, by matching the process data associated with the virtual ID with the cell ID extracted by the cell ID collector;
- and
- transmitting, by the process controller, the process information including matched process data and the cell ID to an upper control system for analysis of a quality of the battery cell or cause of a battery cell degradation.
A battery manufacturing system comprising:
- a process controller stored as program instructions on one or more memory devices which are executed by one or more processing devices, the process controller configured to generate a virtual identifier (ID) corresponding to a battery cell and shift the virtual ID across performance of battery processing operations which comprises first to nth processes and a barcode process, n is a natural number of 2 or greater, included in a battery manufacturing process for the battery cell;
- battery cell processing equipment configured to perform a battery processing operation on the battery cell and to generate process data for the battery cell indicating a work result or a test result related to the battery cell;
- and
- an upper control system configured to evaluate the battery cell based on process information generated by the processing operations included in the manufacturing process for the battery cell;
- wherein:
- the process controller associates the virtual ID with the process data generated for the battery cell;
- the battery cell is physically marked with a cell ID when one of the first to nth processes is performed;
- the process controller matches the process data associated with the virtual ID with the cell ID after extracting the cell ID during the barcode process after the first to nth processes are completed and generates process information;
- and
- the process information including matched process data and the cell ID is transmitted to the upper control system for analysis of a quality of the battery cell or cause of a battery cell degradation.
