<P>PROBLEM TO BE SOLVED: To facilitate shortening of time for identifying a position of each battery module in the case of plural battery modules being serially connected. <P>SOLUTION: Battery modules M1 through Mn each includes: a secondary battery B; a connection terminal T1 connected to an external connection terminal T(+); an information obtainment part 3 for obtaining as voltage-related information a voltage across an anode terminal P(-) and the connection terminal T1; a storage part 43 for pre-storing identification information identifying the battery module itself; and a communication part 42 for transmitting the voltage-related information correlated with the identification information. Further, a battery management device 1 includes: a management-side communication part 22 for receiving the voltage-related information and the identification information that are transmitted from the communication parts 42 of the battery modules M1 through Mn; and a position identification part for identifying positions of the battery modules M1 through Mn within a serial circuit on the basis of each piece of voltage-related information and each piece of identification information received by the management-side communication part 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
