(EN) 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 controls the state of each of the switches of each of the plurality of power storage modules on the basis of at least one of a voltage and a charging rate of the power storage unit.
