<P>PROBLEM TO BE SOLVED: To provide an assembled battery monitoring device which allows for more accurate determination of the presence or absence of disconnection in a detection line by suppressing variation in voltage among cells without opening and closing control of a switch device, compared with a configuration in which resistances connected in parallel to the respective neighboring cells have an identical value of resistance. <P>SOLUTION: In an assembled battery monitoring device 3, resistances R1 in a first group which are connected in parallel to the respective neighboring cells C have different values of resistance from each other. And resistances R2 in a second group which are connected in parallel to the respective neighboring cells have different values of resistance from each other. In addition, a plurality of the cells each have an identical combined resistance of the resistance in the first group and the resistance in the second group which are connected in parallel to the respective cells. <P>COPYRIGHT: (C)2013,JPO&INPIT |
