A power source current control unit (102) controls a magnetic-field current PWM control signal (PW) for PWM-controlling a magnetic-field current of an electric rotating machine (3) so that the value of a power source current flowing in a power source apparatus (2) can be controlled in a non-energization manner to be zero or a value near to zero; in the case where the power source voltage stability determination unit (104) determines that during a predetermined period, variation in a power source inter-terminal voltage value (V) of the power source apparatus (2) is within a predetermined range, the power source SOC estimation unit (101) estimates the state of charge of the power source apparatus (2), based on the voltage value (V) of the power source apparatus (2).
