Abstract
An ECU controls charging of a power storage device such that an SOC of the power storage device does not exceed a prescribed upper control limit. When an electrically powered vehicle moves in a downhill direction with an MG generating travel torque in an uphill direction on an uphill road (downhill-movement state), the ECU allows charging in which the SOC exceeds the upper control limit. Further, when a request to stop a system of the vehicle is made with the SOC exceeding the upper control limit, the ECU performs a discharge process of discharging the power storage device.
