Abstract
An ECU is configured to execute SOC estimation control for estimating an SOC of a battery. The ECU obtains 'first voltage' indicating an OCV of the battery in the SOC estimation control. The ECU controls an engine and a PCU such that the battery is charged with an amount of electric power equal to or larger than a prescribed amount, when the first voltage is within a voltage range where hysteresis occurs. The ECU obtains 'second voltage' indicating an OCV of the charged battery, and estimates the SOC of the battery from the second voltage.
