Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a battery system that makes it possible to reduce the number of current sensors and yet easily bring each current sensor into correspondence with each module. SOLUTION: The battery system is constructed by connecting multiple series lines 50, 60 in parallel and in each series line, at least one battery block 10 is interposed. In each of the multiple series lines 50, 60, a respective single current sensor 51, 61 is placed and the individual battery blocks 10 are respectively connected with control units 11, 21, 31, 41 to construct modules 1 to 4. A module where voltage fluctuates when a current is passed through a specific series line is detected by the voltage monitoring unit of each control unit 11, 21, 31, 41. The correspondence between each current sensor 51, 61 and each module 1 to 4 is defined based on the result of this detection. COPYRIGHT: (C)2009,JPO&INPIT
