Document Type and Number:
WIPO Patent Application WO/2012/128252
Kind Code:
A1
Abstract:
In a power storage system (10) according to the present invention, control devices (16-1 to 16-5) respectively rank connection systems (17-1 to 17-5) on the basis of at least either the past discharging frequency or charging frequency of storage battery modules of the connection systems (17-1 to 17-5). The control devices (16-1 to 16-5) control such that, when discharging, the connection systems discharge in order starting with the connection system that has the smallest discharging frequency among the charged connection systems, and when charging, the connection systems are charged in order starting with the connection system that has the smallest charging frequency among the connection systems determined to require charging, until each said connection system reaches a target charge capacity. Thus, in power storage systems according to the present invention that connect a plurality of connection systems which includes storage battery modules and power conversion devices, the charging frequency and discharging frequency of each power storage system can be leveled.
