A hybrid vehicle illustrated as a representative example of an electrically-powered vehicle includes a chargeable/dischargeable power storage device, a motor configured to generate a vehicle drive force by receiving supply of power from the power storage device, an internal combustion engine as a drive force source, and a generator configured to generate charging power for the power storage device by power generation using an output of the internal combustion engine. If the generator cannot be operated normally, the control unit causes the electrically-powered vehicle to perform limp-home mode traveling by traveling using only the motor. During the limp-home mode traveling, the control device calculates a remaining travelable distance in the limp-home mode traveling, based on at least a remaining capacity of the power storage device and a vehicle speed.
