Document Type and Number:
Japanese Patent JP7422378
Kind Code:
B2
Abstract:
To achieve shortening of a read time, appropriate determination of reuse of a battery cell, and appropriate maintenance management of a battery cell.SOLUTION: Regularity information among respective data regarding non-defective or defective battery cells is extracted from a plurality of past data regarding non-defective or defective battery cells in respective steps, and the regularity information among the respective data regarding the non-defective or defective battery cells is input to extract common points of the non-defective or defective battery cells and singular points of the non-defective and defective battery cells. Then, a determination model based on a conditional expression that can discriminate a non-defective battery cell and a defective battery cell from each other on the basis of the singular points is used to collect data necessary for determination using the determination model from data of the battery cells obtained in the respective steps of a manufacturing process, etc., and each management process, and the determination model is used to determine whether a battery cell is non-defective or defective.SELECTED DRAWING: Figure 1
