To achieve the above-described object, the battery rack includes a plurality of battery modules arranged in a first direction, at least one rack case including a plurality of rack frames configured to mount the plurality of battery modules, and at least one fixing frame including a body in the shape of a plate extending along the plurality of battery modules and a fixing portion formed on one surface of the body and configured to be attached and detached to/from each of the plurality of battery modules. ## Claims ### Claim 1 A battery rack comprising: a plurality of battery modules arranged in a first direction; at least one rack case including a plurality of rack frames configured to mount the plurality of battery modules; at least one fixing frame including a body in the shape of a plate extending along the plurality of battery modules; and a fixing portion formed on one surface of the body and configured to be attached to each of the plurality of battery modules or detached from each of the plurality of battery modules. ### Claim 2 (depends on 1) The battery rack according to claim 1, further comprising a plurality of hanger members respectively coupled to an outer surface of the plurality of battery modules: wherein the fixing portion of the fixing frame has a plurality of hook structures, and wherein each hanger member of the plurality of hanger members is configured to be coupled to a respective one of the plurality of hook structures of the fixing portion of the fixing frame. ### Claim 3 (depends on 2) The battery rack according to claim 2, wherein each of the plurality of battery modules includes a module housing including an upper cover, a base plate, a front cover and a rear cover, and wherein each hanger member of the plurality of hanger members is disposed on an outer side of the rear cover of a respective one of the plurality of module housings. ### Claim 4 (depends on 2) The battery rack according to claim 2, wherein each hanger member of the plurality of hanger members includes: a hanger bar in the shape of a plate in which the hook structure is inserted and fixed on one side, the hanger bar spaced a predetermined distance from the outer surface of the battery module; and a leg extending from each of two ends of the hanger bar, wherein each leg is fixed to the outer surface of the battery module, and wherein each leg has a bent portion. ### Claim 5 (depends on 4) The battery rack according to claim 4, wherein the at least one fixing frame includes a support portion extending vertically along the body and extending from the body such that a surface wraps around at least part of an outer surface of each leg. ### Claim 6 (depends on 5) The battery rack according to claim 5, wherein the support portion is configured to wrap around at least part of the outer surface of each leg of the hanger member even when the hook structure is separated from the hanger bar of the hanger member. ### Claim 7 (depends on 4) The battery rack according to claim 4, wherein upper and lower ends of the body of the at least one fixing frame have a case coupling portion that is coupled to the rack case. ### Claim 8 (depends on 7) The battery rack according to claim 7, wherein the rack case includes a connecting bar connected to the case coupling portion to couple the case coupling portion to the rack case. ### Claim 9 (depends on 8) The battery rack according to claim 8, wherein the case coupling portion of the at least one fixing frame includes: an upper bolting hole configured to couple the plurality of hook structures to the plurality of hanger members when coupled to the connecting bar; and a lower bolting hole spaced from the upper bolting hole at a predetermined distance in the vertical direction and configured to separate the plurality of hook structures from the plurality of hanger members when coupled to the connecting bar. ### Claim 10 (depends on 9) The battery rack according to claim 9, wherein the fixing frame further includes an indicator configured to indicate whether the plurality of hook structures is coupled to the plurality of hanger members. ### Claim 11 (depends on 1) The battery rack according to claim 1, wherein the fixing frame further includes a wall coupling portion configured to fix the fixing frame to a wall adjacent to the battery rack. ### Claim 12 (depends on 1) The battery rack according to claim 1, wherein the rack case includes: a front frame including a plurality of pillars disposed at a front end of the plurality of battery modules and extending in a vertical direction, and a connecting part connecting the pillars in a horizontal direction; a rear frame including a plurality of pillars disposed at a rear end of the plurality of battery modules and extending in the vertical direction and a connecting part connecting the pillars in the horizontal direction; and a top plate disposed on top of the plurality of battery modules, and wherein a lower end of each of the front frame and the rear frame has a bent portion having one surface parallel to the ground, and a bolting hole formed in the bent portion. ### Claim 13 (depends on 12) The battery rack according to claim 12, wherein the battery rack includes two or more rack cases stacked in a vertical direction, wherein each pillar of the front frame and the rear frame has a bolting hole configured to be coupled to another rack case at an upper end, wherein a bolting hole is disposed at the bent portion of the pillar, and wherein the rack case disposed at an upper position is bolt-coupled to a bolting hole of the pillar of the rack case disposed at a lower position. ### Claim 14 (depends on 12) The battery rack according to claim 12, wherein each pillar includes an outer pillar extending in a vertical direction and having one open horizontal side and an inner pillar inserted into the outer pillar and extending in the vertical direction. ### Claim 15 (depends on 14) The battery rack according to claim 14, wherein the outer pillar is a C-shaped steel that is open to one side when viewed in a horizontal cross section, and the inner pillar is in a rectangular pipe. ### Claim 16 (depends on 12) The battery rack according to claim 12, wherein the bent portion of the rear frame has a slit into which a body of a bolt is slidably inserted in a horizontal direction. ### Claim 17 (depends on 1) An energy storage system comprising at least one battery rack according to claim 1.
