A motor generator operates as a generator and a motor. A converter switches a discharge state where power is supplied from a capacitor to the motor generator and a charge state where the capacitor is charged by the power generated from the motor generator. Electric power that is output from the capacitor in the discharge state and electric power that is input to the capacitor in the charge state are controlled. A capacitor voltmeter measures a terminal-terminal voltage of the capacitor. A capacitor ammeter measures charge/discharge current of the capacitor. The measurement result is input from the capacitor voltmeter and the capacitor ammeter to a controller. The controller controls the converter based on the measurement result. |
