A battery system monitoring apparatus for monitoring a cell group having a plurality of battery cells, and includes a cell controller IC which monitors and controls the states of the plurality of battery cells. A battery controller controls the cell controller IC and a plurality of voltage detection lines measure the voltage across the terminals of the battery cell. The voltage detection lines connect positive and negative electrodes of the battery cell, respectively, to a plurality of voltage input terminals of the cell controller IC. A power line connects the positive electrode of the battery cell having the highest potential among the plurality of battery cells to a power supply terminal of the cell controller IC and a ground line which connects the negative electrode of the battery cell having the lowest potential among the plurality of battery cells to a ground terminal of the cell controller IC.
