Abstract: A power supply system includes a plurality of power supply units and a plurality of battery units. Each power supply unit is coupled to a common bus through a first switch. Each battery unit is corresponding to each power supply unit, and is coupled to the common bus through a second switch. Any one of the power supply units turns on the corresponding first switch and turns on the second switches of other battery units so that the power supply unit acquires power electricity from other battery units through the common bus.
