Title:
ENERGY STORAGE SYSTEM, AND ELECTRIC POWER CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/238332
Kind Code:
A1
Abstract:
This energy storage system (21) comprises an input/output terminal pair (29P, 29N) that are connected to an electric power converter (20), and a plurality of power storage units (2_1 to 2_n) that are connected in parallel between one (29P) from the input/output terminal pair and the other (29N) from the input/output terminal pair. The power storage units (2_1 to 2_n) include power storage element groups that are configured from a plurality of power storage elements (4). When one power storage unit from among the plurality of power storage units is exchanged with a new power storage unit, the one power storage unit is exchanged with the new power storage unit such that the difference between current flowing through the remaining power storage units other than the one power storage unit and current flowing through the new power storage unit decreases.
