Disclosed are a battery state notifying unit readily exchangeable between battery packs differing in the number of battery cell, a bus bar module and a battery pack including the battery state notifying unit, and a battery state monitoring system including the battery state notifying unit. The battery state notifying unit (39) includes a plurality of subunits (40) corresponding to every battery cell (21), and the subunits (40) in accordance with a cell temperature signal corresponding to a voltage outputted by a bus bar (32) and a terminal fitting (33), generates a battery state data composed of a digital signal including a data indicating a state of the battery cell (21) corresponding to the subunit (40), and transmits the battery state data to the external battery state monitoring unit (60). |
