PROBLEM TO BE SOLVED: To provide a charge and discharge system capable of ensuring the charge and discharge amount as a system, while performing the equalization of a battery pack.SOLUTION: In a charge and discharge system 1 performing the charge and discharge control of a power storage device 2 constituted of a plurality of battery packs 21(1)-21(n), the plurality of battery packs 21(1)-21(n) are grouped into an equalization cluster executing equalization, an equalization preparation cluster performing preparation of the equalization, and a charge and discharge cluster performing charge and discharge control. The clusters to which respective battery packs belong are subjected to time rotation in the order of the charge and discharge cluster, equalization preparation cluster and equalization cluster, so that at least one battery pack belongs to the equalization cluster, equalization preparation cluster and charge and discharge cluster.SELECTED DRAWING: Figure 1 |
