摘要
The present disclosure provides an open-circuit voltage estimation device that estimates a high-precision open-circuit voltage value, a power storage apparatus, and an open-circuit voltage estimation method. The open-circuit voltage estimation device includes: an open-circuit voltage calculator that calculates an open-circuit voltage value of a secondary cell; a polarization voltage estimator that estimates a component having a relatively large time constant among polarization voltage components of the secondary cell; and an open-circuit voltage corrector that corrects the open-circuit voltage value calculated by the open-circuit voltage calculator with the component having the relatively large time constant estimated by the polarization voltage estimator.
