Original Abstract Submitted

A power supply system is composed of a plurality of cell units connected in parallel. Each of the cell units includes a battery pack and a converter. The control device carries out feedback control only under proportional control such that a unit output voltage which is an output voltage from the cell unit attains to a voltage command inputted from a PCS.
