  • Battery state estimating device
    Patent number: 10890625
    Abstract: A battery model includes a series connection of a direct current resistance model, a charge transfer resistance model derived from the Butler-Volmer equation, and a diffusion resistance model. A battery state estimating device includes a storage unit and a parameter calculating unit. The storage unit stores information on the resistance parameter related to the resistance component of the diffusion resistance model, the time constant parameter related to the time constant of the diffusion resistance model, and the charge parameter of the charge transfer resistance model, in association with temperature information of the secondary battery. The parameter calculating unit calculates each of the parameters corresponding to the detected temperature value based on a detected temperature value of the secondary battery and the information stored in the storage unit.
