A multi-cell battery system includes a plurality of modules connected in series, each of the modules comprising a battery cell and a slave for monitoring a state of the battery cell, and a master for monitoring the state of the battery cell by communicating with the slave of each of the plurality of modules. The master transmits, in order, to the plurality of modules a series of numbers to be numbered on each module as a numbering signal. Each of the plurality of modules numbers the series of numbers in the series-connected order by receiving the numbering signal from the master and executing numbering based on number information contained in the numbering signal when receiving a numbering reception request signal for executing the numbering, and transmitting the numbering reception request signal to a module of a next stage in the series when the numbering is completed.
