Abstract: An energy storage system is provided in this application, which includes at least one energy storage container, and the energy storage container includes a battery management system and m battery clusters. Third controllers corresponding to n battery packs in each battery cluster determine a first third controller connected in series, and set a physical position of the first third controller to a first physical position. An ith third controller in the third controllers corresponding to then battery packs in each battery cluster determines a physical position of the ith third controller based on a position signal sent by an (i−1)th third controller, where i=2, 3, . . . , or n. A first controller determines physical positions of remaining second controllers according to a rapid spanning tree protocol (RSTP) and a known physical position of a second controller.
