A battery rack includes: a housing; a module unit provided in the housing, including a plurality of battery cells, and having at least one vent hole; and a cooling unit provided to face the vent hole in the housing, and including a cooling line in which a coolant is provided, wherein the cooling line is provided so that at least a portion of an outer periphery thereof is melted by heat generated from the module unit to supply the coolant toward the vent hole.

Battery rack

A battery module includes a battery sub-module including a cell support member, at least one battery cell accommodated in the cell support member, and a case provided to partially surround the at least one battery cell, and a first barrier disposed on a first side of the battery sub-module, wherein the at least one battery cell is enclosed and sealed by the cell support member and the case, and the first barrier includes a first protrusion configured to press a part of the case inwardly of the battery sub-module.

Battery module

A battery module is proposed. The battery module includes a plurality of battery sub-modules, and a front cover part configured to cover an outermost stacking surface of the plurality of stacked battery sub-modules. The front cover part includes a front plate including a contact terminal electrically connected to an outside, a bus bar electrically connecting the plurality of battery sub-modules to each other, and a disconnection induction bus bar coupled to an inside end of the contact terminal to press and contact the bus bar, and a switching slider configured to slide between the bus bar and the disconnection induction bus bar.

A plug-in type energy storage system is proposed. The system includes: a plurality of battery racks configured to store power; and a panel configured to control charging or discharging of the plurality of battery racks, where each battery rack includes: a plurality of battery modules configured to store the power; a control module connected to each battery module and the panel to control the charging or discharging of each battery module according to a control signal received from the panel; a conversion module connected to the control module to convert waveforms of the power into direct current or alternating current according to a control signal received from the control module; and a casing configured to accommodate each battery module, the conversion module, and the control module. In addition, the plurality of battery modules and the battery power management unit integrally constitute each battery rack.
