Abstract: An electric storage device management system includes a voltage sensor, a memory, and a controller. The voltage sensor detects a voltage across an electric storage device having a correlation between an open circuit voltage (OCV) and a state of charge (SOC) including a slight change region and a sharp change region. The memory stores information on correlation between OCV and SOC in the sharp change region. The controller is configured to: determine an OCV based on a voltage detected by the voltage sensor; determine whether the defined OCV is within the sharp change region; determine an SOC corresponding to the defined OCV based on the stored information stored if the defined OCV is within the sharp change region; determine the determined SOC as an estimated SOC; and prohibit the determining of the SOC as an estimated SOC if the defined OCV is out of the sharp change region.
