<p><P>PROBLEM TO BE SOLVED: To provide an electric power supply system with high safety at the time of error occurrence. <P>SOLUTION: An electric power supply system includes a plurality of lines having a PCS 2, a PCS management control part 3, a BSU 4, a BMU 5, and storage batteries 7. In the electric power supply system, respective series are connected with one another so that the storage batteries 7 of the respective series can be connected in parallel. Moreover, in the electric power supply system, the PCS management control part 3 periodically transmits information including the own state to the BMU 5 of the same series and the BMU 5 periodically transmits information including the own state to the PCS management control part 3 of the same series, thereby allowing the PCS management control part 3 and the BMU 5 of the same series to detect an error on the partner's side with each other. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
