The invention provides a small and safe storage battery system capable of detecting the point of failure of signal isolation at an early stage, a monitoring device thereof and a hybrid railway vehicle using the same. The storage battery system comprises a plurality of storage batteries (101) being connected in series, an assembled resistance (114) connecting a plurality of resistances (131, 132, 133) in series so as to connect to both terminals of the respective storage batteries (101) to determine a midpoint potential higher than the negative terminal potential and lower than the positive terminal potential, a processing means (112) at the midpoint potential for detecting the respective statuses of the storage batteries (101), and communication means (111) and (113) at negative terminal potentials of the respective storage batteries (101) so as to enable the processing means (112) to communicate with each other or the processing means (112) to communicate with the exterior via isolation means (116) and (117), wherein the processing means (112) includes a current detection means (115) for detecting the current flowing in the assembled resistance (114).
