Abstract
A state estimation apparatus configured to estimate a state of an assembled battery including a plurality of energy storage devices. The energy storage devices each have a small-variation region where an open circuit voltage (OCV) variation amount relative to a residual capacity is smaller, and a variation region where the OCV variation amount relative to the residual capacity is greater than the OCV variation amount relative to the residual capacity in the small-variation region. The state of the assembled battery is estimated based on a varying position of the variation region relative to an actual capacity of the plurality of energy storage devices.
