Document Type and Number:
WIPO Patent Application WO/2019/188889
Kind Code:
A1
Abstract:
The present invention suppresses unevenness in a charging state between battery rows by means of uniform charging with a simple configuration in a power storage system having a multi-parallel battery module. This storage system (100) is characterized by being provided with: a multi-parallel battery module (2) in which battery rows (20) comprising at least one lead battery cell (200) are connected to each other in a plurality of parallel rows; switches (4_1 to 4_n) which are provided to correspond to the respective battery rows and are connected in series between the battery rows and AC/DC conversion devices (3) corresponding to each other; and a control device (1), wherein the control device turns on the switches and supplies electric power from the AC/DC conversion devices to the battery rows so as to fully charge the battery rows by means of the uniform charging, and determines whether the uniform charging has been completed for the respective battery rows and turns off the switches of the battery rows to which the uniform charging is determined to have been completed.
