蓄電池の特性推定装置および特性推定方法

Japanese Patent JP7069412

B2

Provided is a characteristic estimation device for a storage battery including: a voltage detection unit configured to detect a terminal voltage of the storage battery; a time-series data acquisition unit configured to acquire time-series data on the terminal voltage in a stopped state of the storage battery; a model provision unit configured to provide a storage battery model; and a model parameter estimation unit configured to estimate a model parameter of the storage battery model based on the time-series data on the terminal voltage acquired by the time-series data acquisition unit and on the storage battery model provided by the model provision unit. The storage battery model includes an OCV term for expressing OCV of the storage battery and an interparticle diffusion term which is based on a fundamental solution of a one-dimensional diffusion equation expressing ion diffusion among particles forming electrodes of the storage battery.
