Abstract
Provided is a storage battery diagnostic device including: a positive/negative electrode OCV model function generation unit () configured to generate a positive electrode OCV model function and a negative electrode OCV model function for N storage batteries by a sum of OCV element functions; and a storage battery model function parameter group estimation unit (), which is configured to generate a storage battery model function based on the positive electrode OCV model function and the negative electrode OCV model function, and to generate an evaluation function L indicating an error between the time-series data stored in the data storage unit () and time-series data on estimation data calculated by using the storage battery model function, to thereby calculate such an optimal group of estimation parameters of the storage battery model functions for the respective storage batteries as to minimize a value of the evaluation function L.
