A battery cell monitoring system includes multiple battery monitoring circuits, each connected to a corresponding battery cell, and a microcomputer for controlling the monitoring circuits. The battery monitoring circuits include a data output circuit that outputs a data signal corresponding to the monitoring results for the battery cell monitored thereby and a multiplexer that outputs either the monitoring results received from the data output circuit or monitoring results received from another battery monitoring circuit. The battery cell monitoring circuit includes a flip-flop circuit receiving a clock signal and the signal output from the multiplexer which is latched in synchronization with the clock signal.
