Abstract
An electric storage device management system includes a voltage sensor configured to detect a voltage across an electric storage device having a correlation between an open circuit voltage (OCV) and a state of charge (SOC), the correlation including a slight change region and a sharp change region, the slight change region being a region in which a variation in OCV relative to the SOC is equal to or smaller than a reference value, and the sharp change region being a region in which the variation is larger than the reference value.
