摘要： The invention enables to control the currents charged to and discharged from respective power storage systems individually even if the properties such as the types, the ages and the power storage capacities of the means of energy storage constituting the power storage systems mounted in dispersed manner in multiple cars vary, to thereby equalize and elongate the replacement period and cut down the replacement work of the power storage systems. The present system provides a current control means to power lines provided to share power for driving power storage systems and inverter units mounted in dispersed manner among multiple cars so as to individually control the current being charged to and discharged from the respective power storage systems, wherein a specific power storage system out of the plurality of storage units mounted in dispersed manner tomultiple cars controls a current control means so as tomaintain the voltage value of a power line for sharing the power for driving inverter units among cars to a constant value, and the remaining power storage systems control the current control means so as to reduce or increase the charge-discharge power or current so that the dispersion of deterioration indexes of means of energy storage is minimized, and further, the specific power storage system selects a power storage system with a means of energy storage having a deterioration index closest to the average value.
