Provided is a power-generation control device and a power-generation control method for a hybrid vehicle, which are capable of suppressing a temperature rise of an electric motor while controlling a field-weakening current to flow through the electric motor to protect the electric motor and a battery even when an induced voltage increased by an increase in rpm of the electric motor exceeds an allowable voltage of the battery. Power generation by an electric motor is stopped when a voltage of a battery is equal to or higher than a predetermined first voltage, and an in-vehicle electric load is supplied with power generated by the electric motor and a power-generation amount by the electric motor is controlled so that the voltage of the battery becomes equal to a predetermined second voltage, when the voltage of the battery is lower than the predetermined second voltage.
