CHARGE AND DISCHARGE CONTROL DEVICE, CHARGE AND DISCHARGE SYSTEM, CHARGE AND DISCHARGE CONTROL METHOD, AND CHARGE AND DISCHARGE CONTROL PROGRAM

According to an approach, there is provided a charge and discharge control device (7) that controls charging and discharging of a battery module (2) in which a plurality of cell blocks (B to B), each including one or more unit cells (11), are connected in parallel to one another. A controller (12) of the charge and discharge control device (7) controls a current flowing through each of the cell blocks (B to B) based on at least one of a current load of each of the cell blocks (B to B) or a parameter relating to the current load.
