<p>An electrically powered vehicle includes an electric motor, an internal combustion engine, a power storage device configured to input and output electric power to and from the electric motor, a power generation mechanism generating charge power for the power storage device by electric power generation using an output of an internal combustion engine, a charging state estimation unit for estimating a remaining capacity of the power storage device based on a state value of the power storage device, and a charge/discharge control unit for controlling charging and discharging of the power storage device based on the remaining capacity estimate value by the charging state estimation unit. The charge/discharge control unit includes a charge instruction unit for, in the case where the remaining capacity estimate value falls below a predetermined lower limit value, controlling the internal combustion engine to be in the load operation state to generate charge power and controlling the internal combustion engine to be in the no-load operation state or in the stopped state when it is determined that a prescribed charge termination condition is satisfied. The charge instruction unit sets the charge termination condition such that the charging time for the power storage device is shortened as the charge power that can be received by the power storage device in the present state is decreased.</p> |
