A storage battery arrangement includes a plurality of storage battery cells connected in series, a central network node designed to transmit data using the storage battery cells and connected to the series connection of storage battery cells, a plurality of cell network nodes designed to transmit data using the storage battery cells, where each cell network node is connected in parallel to a storage battery cell. The storage battery arrangement also includes a control device designed to command at least one first cell network node to apply a test signal having at least one predetermined frequency to a first storage battery cell to which said first cell network node is connected, and to command a second cell network node connected to a second storage battery cell to determine, based on a signal response of the second storage battery cell to the test signal, at least one condition of the second storage battery cell.
