Power distribution system using multiple rechargeable power sources and method for distributing power using multiple rechargeable power sources

A power distribution system using multiple rechargeable power sources, comprising:

• multiple rechargeable power units, each rechargeable power unit having:
• a rechargeable power source storing or outputting DC (Direct Current) power;
• and
• a power regulator electrically connected to the rechargeable power source to regulate the DC power outputted from the rechargeable power source;
• a power distribution board electrically connected to the power regulators of the multiple rechargeable power units to converge the DC power received from the rechargeable power sources;
• a power converter electrically connected to the power distribution board, converting the DC power received from the power distribution board into AC (Alternating Current) power, and supplying the AC power to a load;
• and
• a control device electrically connected to the multiple power regulators and the load;
• wherein
• the control device creates an output power reference table according to multiple power setting values and an output power range and battery efficiency of each rechargeable power unit, wherein the output power reference table includes the multiple power setting values and multiple pieces of power distribution information corresponding to the respective power setting values, and each piece of power distribution information has multiple output power values corresponding to the respective rechargeable power sources;
• the control device selects the power setting value and the piece of power distribution information from the output power reference table according to a consumed power value of the load and controls the power regulators of the multiple rechargeable power units to regulate power according to the selected piece of power distribution information for the multiple rechargeable power sources to simultaneously supply power according to the multiple output power values of the selected piece of power distribution information to the load.
