<p>This charging/discharging device (30) determines ahead of time the capacity-voltage characteristics of each storage battery (22) configuring a battery block (20), and from the state at the current point in time, continues charging/discharging under set conditions of the battery block as a whole. The capacity of another storage battery when one storage battery has reached a charging upper limit is estimated on the basis of the capacity-voltage characteristics, and the capacity of each storage battery is added together, the result being considered a first capacity; the capacity of another storage battery when one storage battery has reached a discharging lower limit is estimated on the basis of the capacity-voltage characteristics, and the value resulting from adding the capacity of each storage battery is considered to be a second capacity; and the value resulting from subtracting the second capacity from the first capacity is estimated to be the fully charged capacity of the battery block as a whole.</p> |
