An acquirer acquires driving data of an electrically-powered moving body. A predictor predicts, based on the driving data of the electrically-powered moving body, an aging failure of an electromechanical transducer including a motor driving a driving wheel of the electrically-powered moving body and a drive circuit driving the motor. The driving data include an input voltage of the drive circuit, an input current of the drive circuit, a rotational speed of the motor driven by the drive circuit, and a rotational torque of the motor. The predictor predicts the aging failure of the electromechanical transducer based on a change of a value statistically representing a relationship between an input electric power of the drive circuit, obtained based on the input voltage and the input current of the drive circuit, and a shaft output power of the motor, obtained based on the rotational speed and the rotational torque of the motor.
