<P>PROBLEM TO BE SOLVED: To inhibit a circulation current from running among electric storage devices connected in parallel during maintenance. <P>SOLUTION: A control device is provided, including: a control unit 51 that carries out a charge-discharge control of an electric storage system including a plurality of electric storage devices 20A, 20B connected in parallel; and an abnormality detection unit 52 that detects abnormality in components disposed in each of the electric storage devices and relating to charge-discharge processes. When abnormality of a component is detected in a part of the plurality of electric storage devices connected in parallel, the control device controls in such a manner that power of electric storage devices other than the electric storage device having the abnormal component is output to a motor 33 for traveling while prohibiting charging/discharging of the electric storage device having the abnormal component. Further, when a difference in the charging capacity between the electric storage device having the abnormal component and other electric storage devices excluding the electric storage device having the abnormal component decreases to a predetermined value or less, the control device controls to terminate the power supply from the electric storage system to the motor 33 for traveling. <P>COPYRIGHT: (C)2013,JPO&INPIT |
