Title:

DEVICE FOR CALCULATING EXPANSION/CONTRACTION AMOUNT, PROGRAM FOR CALCULATING EXPANSION/CONTRACTION AMOUNT, INDIVIDUAL IDENTIFICATION DEVICE, AND INDIVIDUAL IDENTIFICATION PROGRAM

Document Type and Number:

Japanese Patent JP2023112470

Kind Code:

A

Abstract:

To provide a device for calculating the expansion/contraction amount, a program for calculating the expansion/contraction amount, an individual identification device, and an individual identification program that can identify characteristic points in 3D data of an electrode in order to calculate the deformation of the electrode based on the expansion/contraction amount of the electrode in order to improve the energy efficiency of a battery.SOLUTION: An expansion/contraction amount calculation device 1 calculates the deformation amount of an electrode by calculating the expansion/contraction amount of the electrode on the basis of 3D data of the electrode. The expansion/contraction calculation device 1 includes a control unit 10 that has a characteristic point identification unit 11 that identifies characteristic points from array information of an active material in the 3D data, a coordinate generating unit 12 that generates coordinates for calculating the deformation amount on the basis of relative location information of the characteristic points, and a calculation unit 14 that compares first 3D data with second 3D data and calculates the expansion/contraction amount and deformation amount of the electrode.SELECTED DRAWING: Figure 1
