摘要

A current integration method in which an SOC of an energy storage device is estimated by time integration of a current flowing in/from the energy storage device, and an OCV method in which an SOC is estimated, based on a V-SOC correlation between a voltage and a state of charge of the energy storage device can be executed. When this V-SOC correlation is sectioned into a plurality of SOC regions, if a first SOC region and a second SOC region are different from each other, a predetermined value of the second SOC region is employed as an SOC estimated value, the first SOC region being the SOC region that the SOC estimated by the current integration method belongs to, and the second SOC region being the SOC region that the SOC estimated by the OCV method belongs to. The predetermined value may be set between a boundary value on a side close to the first SOC region of boundary values sectioning the second SOC region, and an intermediate value of the second SOC region.
