DESIGN DEVICE, DESIGN METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a design device capable of accurately evaluating an operating life of an assembled battery made up of a plurality of storage battery cells.SOLUTION: A statistical cell deterioration characteristic derivation section 102 derives statistical cell deterioration characteristics, which is statistical data on a plurality of cell deterioration characteristics, on the basis of the plurality of cell deterioration characteristics which are respective deterioration characteristics of a plurality of storage battery cells used in an assembled battery. A calculation procedure derivation section 103 derives a calculation procedure to obtain statistical assembled battery deterioration characteristics which is evaluation data obtained by evaluating the deterioration characteristics of the assemble battery on the basis of connection structure information indicating a connection structure between the plurality of storage battery cells. A statistical assembled battery deterioration characteristic derivation section 104 derives statistical assembled battery deterioration characteristics from the statistical cell deterioration characteristics in accordance with the calculation procedure. A life distribution derivation section 105 evaluates an operating life of the assembled battery on the basis of the statistical assembled battery deterioration characteristics.SELECTED DRAWING: Figure 1
