Abstract
An ECU includes a nonvolatile memory. An SOC acquisition unit acquires SOCc, which is a current SOC of a battery. A ΔSOC calculation unit calculates a difference ΔSOC (=|SOCm−SOCc|) between an SOCm (memory SOC) stored in the nonvolatile memory and the SOCc. A rewriting unit rewrites the SOCm stored in the nonvolatile memory to the SOCc, on the condition: ΔSOC>threshold value Sduring charging, ΔSOC>threshold value Sduring discharging, or ΔSOC>predetermined value α when an ignition switch is operated to switch from ON to OFF.
