摘要

PROBLEM TO BE SOLVED: To provide a method for determining a constraint condition capable of estimating a parameter with high accuracy. SOLUTION: This is a method for determining a constraint condition 47 used for estimating a parameter in a model of a storage battery 10, and by measuring the characteristics of the storage battery 10 under each of a plurality of different operating conditions, a plurality of characteristic measurement values are obtained. Is included, and the range of the constraint condition is determined based on the plurality of characteristic measurement values. [Selection diagram] Fig. 1
