A battery system monitoring apparatus that monitors a battery system is provided having a cell group having a plurality of unit cells connected in series, including: a first control device that controls the cell group; and a plurality of voltage detection lines that connect positive electrodes and negative electrodes of the unit cells to the first control device, for measuring inter-terminal voltages of the unit cells. The first control device includes a balancing switch connected between the voltage detection line connected to the positive electrode of each unit cell and the voltage detection line connected to the negative electrode thereof for conducting balancing discharge of the unit cell, for each of the unit cells. A first resistor is disposed in series with each of the voltage detection lines, a first capacitor is connected between the voltage detection line, and a GND which is a lowest-level potential of the cell group.
