<P>PROBLEM TO BE SOLVED: To provide a power storage system which is low-cost and has high reliability. <P>SOLUTION: Respective positive polarity and negative polarity voltages of a plurality of battery cells 201 which a cell group corresponding to one of first integrated circuits 330a electrically connected to each other via a voltage transmission circuit 337 has are taken into the other of the first integrated circuits 330a electrically connected to each other via the voltage transmission circuit 337 and a second integrated circuit 330b, and inter-terminal voltages between respective positive polarities and negative polarities of the plurality of battery cells 201 which the cell group corresponding to one of the first integrated circuits 330a has are detected in both one and the other of the first integrated circuits 330a and the second integrated circuit 330b, whereby redundancy is achieved due to duplexing of a voltage detection system. <P>COPYRIGHT: (C)2013,JPO&INPIT |
