<P>PROBLEM TO BE SOLVED: To provide a method and device for performing charge/discharge control of an electrified section such that the SOC includes a predetermined value required for running in a non-electrified section for a train continuously running in the non-electrified section after the electrified section. <P>SOLUTION: A vehicle with a drive battery, which operates across the electrified section and the non-electrified section, includes a charge/discharge control system for a secondary battery 15. In this control system, constant-current constant-voltage charge control 31 is performed for battery-charge demand, pantagraph current restrained control 32 is performed for battery-discharge demand, and battery current zero control is performed when no charge/discharge is needed. Each of these control outputs is made to correct the command value of a DC voltage control 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
