[Problem to be Solved] To provide a battery state notifying unit, a bus bar module, a battery pack and a battery state monitoring system allowing the number of electric wires guided to a unit monitoring a battery state to reduce, and signal voltage applied to the electric wires to lower. [Solution] A battery power source system 1 is provided with a battery state notifying unit 40 corresponding to each the battery pack 10, wherein the battery state notifying unit 40 generating battery state information of digital signal including information indicating electrode voltage and temperature of the battery cells 21, and transmitting the battery state to the battery state monitoring unit 60, the information being based on cell voltage signal corresponding to electrode voltage outputted from terminal fittings 33 of the battery pack 10, and cell temperature signal corresponding to voltage outputted from temperature sensor 34. |
