<p>A charge/discharge control system for a storage cell assembly, wherein a parallel off is appropriately cancelled when a plurality of cell blocks is connected in parallel, and a parallel off subsequently occurs in which one of the cell blocks becomes disconnected from parallel connection. A charge/discharge control system for a storage cell assembly comprises a plurality of cell blocks (32) each connected in parallel to a charge/discharge main bus (18) via protective resistors (22), and a plurality of switches (24) connected in parallel to the protective resistors (22), between the charge/discharge main bus (18) and the plurality of cell blocks (32). In a state in which the plurality of switches (24) are all on, when one of the plurality of switches (24) turns off and a parallel off occurs, a charge/discharge control device (52) performs processing for throttling, in accordance with a pre-set reference, the charge/discharge power that flows to the charge/discharge main bus (18). When the parallel off is cancelled by the throttling processing, the charge/discharge power is restored.</p> |
