ABSTRACT:
Upon detecting a disconnection, a current detection circuit supplies a detection current to connection lines between each cell and the corresponding voltage monitoring circuit. The detection current is larger than a consumption current flowing via each voltage monitoring circuit in a normal state. When the disconnection occurs, a diode changes a route in which the detection current flows so as to reverse an electric potential relation between a positive-side power line and a negative-side power line of the corresponding cell and a reverse detection circuit detects the reverse of the electric potential relation to output a disconnection detection signal.
