Title:
STORAGE BATTERY CONTROL DEVICE AND ELECTRICITY STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/116679
Kind Code:
A1
Abstract:
A storage battery control device (2) comprises: a plurality of first control devices (21) that are provided in respective strings (ST1 to STx) and control string auxiliary units (5); and a second control device (22) that communicates with the plurality of first control devices (21) and a higher-level server (7) outside an electricity storage system (1). The first control devices (21) acquire information on the states of the strings (ST1 to STx) and transmit the information to the second control device (22). The second control device (22) calculates, on the basis of the charging/discharging power instruction value of the electricity storage system (1) received from the higher-level server (7) and the information on the states of the plurality of strings (ST1 to STx) received from the plurality of first control devices (21), charging/discharging power instruction values to be allocated to the respective plurality of strings (ST1 to STx) and sends the charging/discharging power instruction values to the first control devices (21).
