<P>PROBLEM TO BE SOLVED: To solve the problem that, even when a measured voltage of a cell is settled within a normal range, there is the case where disconnection may occur between the cell and a detection terminal and in such a case, the presence of the disconnection cannot be detected. <P>SOLUTION: A disconnection detection apparatus comprises: terminals (q<SB POS="POST">1</SB>to q<SB POS="POST">N+1</SB>) provided in a plurality of connecting parts connecting a plurality of cells in series; a voltage measuring section (4) connected to a plurality of terminal couples provided in connecting parts in both ends of each cell, among the plurality of terminals, for measuring voltage between the plurality of terminal couples; a terminal voltage control section (9) which controls voltage of at least one terminal for each of the plurality of terminal couples; and a disconnection determination section (7) which determines the presence/absence of disconnection between the terminal and the connecting part on the basis of the voltage between the terminal couples measured by the voltage measuring section in the case where the voltage of the terminal is changed by the terminal voltage control section. <P>COPYRIGHT: (C)2013,JPO&INPIT |
