PROBLEM TO BE SOLVED: To improve output characteristics by increasing chances of a plurality of sub-batteries simultaneously discharging while simplifying facility configuration in a power supply facility using the plurality of sub-batteries.SOLUTION: The power supply device includes: a plurality of power storage modules connected in parallel, each of which includes a power storage unit and a switch that brings the power storage unit and a driving device of a transportation device into a conductive state or a cutoff state; and a control device that calculates an increase/decrease trend of deviation of at least one of a charge rate and a voltage of the power storage unit in the plurality of power storage modules, and controls the state of each of the switches of each of the plurality of storage modules on the basis of the increase/decrease trend.SELECTED DRAWING: Figure 9
【課題】複数のサブバッテリを用いた電源設備において、設備構成を簡素化しつつ、複数のサブバッテリが同時に放電を行う機会を増加させ、出力特性を向上させること。【解決手段】電源装置は、各々が蓄電部と、前記蓄電部と輸送機器の駆動装置との間を導通状態または遮断状態にするスイッチとを備える、並列に接続された複数の蓄電モジュールと、複数の前記蓄電モジュールにおける前記蓄電部の充電率および電圧の少なくとも一方の偏差の増減傾向を算出し、前記増減傾向に基づき、複数の前記蓄電モジュールの各々の前記スイッチの状態を制御する制御装置とを備える。【選択図】図9
