Description

Technology Field

[65535] The present invention relates to an energy storage system, and specifically, to an assembleable modular energy storage system container. Background Technology With the expansion of energy supply, the demand for large-capacity Energy Storage Systems (ESS) is surging, and containerized ESS are widely used for their convenience in installation and mobility. Conventional containerized ESS systems can house various control and electrical components within standardized cargo containers. These containers can be designed based on a skid, an integrated support structure located at the bottom. The skid provides robust support for multiple battery racks weighing thousands of kilograms from below and serves as a passageway for complex power cables and cooling water piping between system components. However, these conventional integrated containers may be subject to transport weight limitations. As energy density increases, filling a standard container larger than 20 feet with batteries can result in excessive weight that exceeds the shipping weight limits of container ships, thereby reducing logistics efficiency. Furthermore, conventional integrated containers may entail construction complexity at the installation site. To connect containers to the external power grid, a large volume of cable laying and wiring work must be performed individually, which can extend the construction period and increase the risk of fire due to assembly errors.

Therefore, the definition should be based on the content throughout this specification. FIG. 1 illustrates, by way of example, a modular energy storage system container (100A) and an expandable container system (100B) according to one embodiment of the present disclosure. Referring to FIG. 1, a modular energy storage system container (100: 100A and 100B) comprising a plurality of modular blocks is disclosed. For example, reference numeral 100A refers to a modular energy storage system container, and reference numeral 100B may refer to a combined structure or combined system of modular energy storage system containers. In the present disclosure, a modular block may mean an independent functional container constituting a modular energy storage system container (100). For example, a modular block may be formed to have an external shape corresponding to the international standard 10-foot (ft) Bi-con standard.In one embodiment, the modular block may be manufactured independently by being divided into a battery block (110), an electrical block (130), and a chiller block (120) according to the main devices and functions housed inside. In one embodiment, the modular block may have a coupling structure that supports physical, electrical, and fluid connections with one another, thereby forming an architectural structure that allows for vertical stacking as well as horizontal expansion to meet the required capacity and site conditions of the installation site. In one embodiment, the battery block (110) may have a plurality of batteries for storing energy and a DC power control device (DCPM) inside that controls and manages power output from the battery rack. In one embodiment, a deflagration venting system (DVS) may be installed on the wall (e.g., rear wall) of the battery block (110) to safely vent pressure and flames generated during an internal explosion. In one embodiment, the battery block (110) may include an air intake and / or exhaust fan to vent internal heat generated by the battery pack to the outside. In this disclosure, a modular energy storage system container (100) may refer to an integrated energy solution formed by combining a plurality of modular blocks to store and manage large-capacity power (e.g., 10 MWh per 30-foot installation area). In one embodiment, the modular energy storage system container (100) may include at least one battery block (110) including a battery rack and a DC power control device for controlling the battery rack, an electrical block (130) including a power conversion device (PCS), and a chiller block (120) providing cooling to the battery block (110). In one embodiment, the modular energy storage system The container (100) may be in the form of a battery block (110), an electrical block (130), and a chiller block (120) combined in various ways.In one embodiment, the modular energy storage system container (100) may be in a form in which a battery block (110), an electrical block (130), and a chiller block (120) are directly connected to each other in a horizontal or vertical direction. In one embodiment, the modular energy storage system container (100) may be in a form in which the battery block (110), the electrical block (130), and the chiller block (120) are additionally connected by a separate common lower support structure (140). Depending on the implementation mode, the modular energy storage system container (100) may be configured such that components of the common lower support structure (140) are included or placed in other modules of the modular energy storage system container (100) without a separate common lower support structure (140). The modular energy system container (100) may have a structure that can be connected to other modular energy system containers (e.g., in parallel). In one embodiment, the energy storage system container may be an integrated infrastructure structure for storing, controlling, converting, and supplying a large amount of power to an external power grid. The modular energy storage system container illustrated in FIG. 1 of the present disclosure may be composed of a first modular energy storage system container (100A) that operates as a single unit and an expandable (or combined) container system (100B) in which multiple single units are combined in parallel to collect large-scale power. In the present disclosure, "container" refers to a single container, and "container system" may refer to a combined structure of multiple containers. Although FIG. 1 exemplarily illustrates the first modular energy storage system container (100A) as a structure including a skid (140), depending on the implementation mode, a structure that does not include the skid (140) and in which the components of the skid (140) are arranged (e.g., distributed) within the modules inside the container (100A), such as in FIG. 6, may also be included within the scope of the present disclosure.The first modular energy storage system container (100A) may include a plurality of individual blocks (120, 130, 140) that are physically and spatially divided according to functional purposes, and these may be stacked and combined in horizontal and vertical directions to form a single three-dimensional block-type architecture. As an example of a parallel configuration, the specifications of the system may be expanded in various ways by combining individual blocks of 10-foot (ft) bi-con specifications into a 20-foot container, a 30-foot high-cubic (HC) container, or a mega-scale unit of 40 feet or more. Through this modular block division and stacking architecture, load limiting issues that occur during the transportation of containers can be fundamentally avoided, and cooling and power modules can be selectively combined to suit the site environment (e.g., desert, extreme environment, humid region), thereby maximizing the space efficiency, installation freedom, and transportation cost reduction effects of the container. The modular blocks of the container (100A) may include at least one battery block (110) that accommodates a battery rack, an electrical block (130) that accommodates a power conversion device (PCS), and a chiller block (120) that supplies cooling water. The battery block (110) may be arranged in a vertical stacking structure of, for example, two layers or more, and the chiller block (120) and the electrical block (130) may be stacked vertically on one side of the battery block (110) and combined. For example, a structure in which the chiller block (120) is located on the first floor and the electric block (130) is located on the second floor, or a structure in which the electric block (130) is located on the first floor and the chiller block (120) is located on the second floor, or a structure in which they are separated and accommodated within an integrated housing by a partition wall, may all be included within the scope of the container structure of the present disclosure.Through this functional block independence structure, when a specific device (e.g., chiller or PCS) fails or is replaced by a next-generation high-efficiency model, only the corresponding block can be individually separated without dismantling the entire system, thereby drastically reducing maintenance time and dramatically improving the life cycle efficiency of the system. In one embodiment, the battery block (110), electrical block (130), and chiller block (120) may each be formed in a 10-foot (ft) bi-con standard. In addition, the multiple blocks may be configured so that two blocks are combined during transport to be transported in a 20-foot high-cubic container unit, thereby avoiding the container transport weight limit that occurs when batteries are loaded inside. In one embodiment, the common lower support structure (140) may include components located at the bottom of the modular energy storage system container (100) to physically support the multiple modular blocks placed on top and manage the infrastructure inside the container. For example, the common lower support structure (140) may include components for managing power within the modular energy storage system container (100) (e.g., power supply unit, power control unit, power converter, transformer, heat exchanger, battery management system, power path and busbar for connecting power), and a device for detecting a fire within the modular energy storage system container (100) and providing an alarm thereon. In the present disclosure, the common lower support structure (140) may correspond to or include a skid. In one embodiment, the busbar may be a rigid conductor power path provided to efficiently transmit high voltage and high current power within the modular energy storage system container (100) according to the present disclosure.For example, the busbar can serve as a main power line to collect direct current power output from multiple battery racks and transmit it to a power converter, or to transmit alternating current power converted by the power converter to an external power grid. In one embodiment, in a structure (100A) including a common lower support structure (SKID, 140), the busbar can be pre-embedded and arranged in parallel with the cooling water pipe (200) in the internal space. This can provide the effect of eliminating complex wiring work at the site and supporting rapid power system formation through standardized block placement alone. In one embodiment, the busbar can be pre-embedded and embedded inside the common lower support structure during the factory manufacturing process prior to installation at an external site. For example, the busbar formed from a solid metal body can provide structural rigidity that does not deform even under electromagnetic repulsion or external vibrations. In one embodiment, the busbar can contribute to increasing the thermal stability of the container or container system by effectively dissipating heat generated during current flow through a large surface area. In one embodiment, the busbar may be provided with an insulating coating, a heat shrink tube, or a separate insulating support on its surface to prevent short-circuit accidents in a high-voltage environment. In one embodiment, the busbar can be formed to extend along the length of the internal space of a common lower support structure in place of a cable, thereby improving the space efficiency and electrical efficiency of the container. Consequently, the busbar can serve as a "main line of power" that electrically integrates each of the modularized blocks and can be a core power interface component of the container that maximizes internal space efficiency and reduces power loss by minimizing cable usage. For example, the common lower support structure (140) is formed of a steel frame to firmly support loads such as high-density battery racks and heavy power conversion devices (PCS), and can serve to protect internal components from moisture or impact from the ground.For example, the common lower support structure (140) may be characterized by performing complex functions through a hollow space formed inside, going beyond a simple support structure. For example, the common lower support structure (140) may perform the function of providing a path to distribute power and cooling of the modular energy storage system container (100). For example, the common lower support structure (140) may provide a routing path in which DC cables connecting the modular blocks, AC power lines, and communication cables are laid. For example, the common lower support structure (140) may provide an integrated routing environment in which cooling water piping for delivering cooling water supplied from the chiller block (120) to each battery module is provided in parallel with the power path. In one embodiment, the modular energy storage system container (100A) may be combined by including at least one or a plurality of battery blocks (110) (e.g., four), at least one electrical block (130), and at least one chiller block (120), and additionally including at least one common lower support structure (140). For example, when there are four plurality of battery blocks (110), the plurality of battery blocks (110) may be provided in a stacked form of two on top of the common lower support structure (140), and the electrical block (130) and chiller block (120) may be provided on top of the common lower support structure (140) at at least one side (e.g., left, right, top, bottom) of the battery blocks (110). For example, the electric block (130) may be located to the right of the battery block (110) on the upper part of the common lower support structure (140), and the chiller block (120) may be located on the upper part of the electric block (130). In one embodiment, if there are two or more battery blocks (110), they may be arranged in a vertical two-layer stacked configuration.In one embodiment, when the battery blocks (110) are arranged in a stack, the chiller blocks (120) include independent first chillers and second chillers, and without additional pump or motor mounting, the piping of the first chiller can be directly connected to the battery blocks (110) of the upper layer, and the piping of the second chiller can be directly connected to the battery blocks (110) of the lower layer. In one embodiment, the modular energy storage system container (100B) may be in the form of multiple modular energy storage system containers (100A) combined. For example, the modular energy storage system container (100B) may be in the form of one additional modular energy storage system container (100A) located at at least one side (e.g., left, right, top, bottom) of the modular energy storage system container (100A) and combined. In one embodiment, the modular energy storage system container (100) may be in the form of a plurality of modular energy storage system containers (100) combined, each comprising a different number of battery blocks (110), chiller blocks (120), and electrical blocks (130), and the number of each of the battery blocks (110), chiller blocks (120), and electrical blocks (130), the number of modular energy storage system containers (100) combined, and the location and method of combination are not limited to the examples listed. In one embodiment, the modular energy storage system container (100) may be in the form of a battery block (110), electrical blocks (130), and chiller blocks (120) directly combined in a mutually horizontal or vertical direction without a separate common lower support structure (140). In one embodiment, a modular energy storage system container (100) without a separate common lower support structure (140) may be provided in such a way that the components included in the common lower support structure (140) are included in the battery block (110), electrical block (130), and chiller block (120) instead of the common lower support structure (140).For example, the battery block (110) may include a DC power control device that controls power by being directly connected to a battery rack built into the inner lower part of the battery block (110) in place of the common lower support structure (140). For example, the electrical block (130) may be configured to include a transformer, an uninterruptible power supply, a dehumidifier, a fire alarm controller, and a heat exchanger together with a power converter inside, thereby replacing the function of the common lower support structure (140). Accordingly, it is possible to implement an energy storage system container (100A) without the common lower support structure (140). In one embodiment, the modular energy storage system container (100) may include a cable connected to an external site power grid that is provided on the outside of the container and is connected to transmit and receive power to and from the container. In one embodiment, the cable may be directly fed into the container through the rear panel or lower panel of the electrical block (130) and connected to a transformer or power converter inside the electrical block (130). In one embodiment, the electrical connection between the DC power controller of the battery block (110) and the power converter of the electrical block (130) may be directly coupled to each other via a block connecting member including a quick connector and a cable gland structure provided on the lower left or right side of each block. In one embodiment, a gland structure including a gasket, a lock nut, and a dedicated connector and a flexible cable may be applied to the hole of the block connecting member through which the cable between the blocks passes. For example, the gland structure including a gasket, a lock nut, and a dedicated connector and the flexible cable can absorb vibrations caused by the movement of the modular energy storage system container (100) and errors caused during assembly, and can perform waterproof or dustproof functions. For example, absorbing vibration and error can mean reducing generated vibration and reducing errors that occur during assembly.In one embodiment, the cooling water piping between the chiller block (120) and the battery block (110) is directly connected in a horizontal or vertical direction through a quick connector provided on the joint surface of the chiller block (120) and the battery block (110), and the cooling water generated in the chiller block (120) can be directly supplied to each battery of the battery block (110). In one embodiment, as the common lower support structure (140) is omitted, the routing of cables and piping between the blocks is routed only in a horizontal direction between the plurality of battery blocks (110), and can be routed simultaneously in horizontal and vertical directions from the chiller block (120) and the electrical block (130) to the battery block (110). In one embodiment, as the common lower support structure (140) is omitted, the power output from the battery block (110) is transmitted to the busbar provided in the electrical block (130) after sequentially passing through the DC power control device, the power converter of the electrical block, and the fuse, and then directly output to the external site power grid. In one embodiment, a busbar may refer to a rigid conductive power path provided to efficiently transmit high voltage and high current power within a modular energy storage system container (100) according to the present disclosure. For example, a busbar may serve as a main power line for collecting direct current power output from a plurality of battery racks and transmitting it to a power converter, or for transmitting alternating current power converted by a power converter to an external power grid. For example, in a structure including a common lower support structure (140), the busbar may be pre-embedded and arranged in parallel with cooling water pipes within the space of the common lower support structure (140). This can provide the effect of eliminating complex wiring work at the site and supporting rapid power system formation through standardized block placement alone. For example, a busbar formed of a rigid metal body may provide structural rigidity that does not deform even under electromagnetic repulsion or external vibrations.In addition, busbars can contribute to enhancing the thermal stability of the system by effectively dissipating heat generated during current flow through their large surface area. For example, to prevent short-circuit accidents in high-voltage environments, busbars may be equipped with an insulating coating, heat-shrink tubing, or separate insulating supports on their surfaces. Consequently, the busbar serves as a 'power mainline' that electrically integrates each modularized block and can be a key power interface component that maximizes internal space efficiency and reduces power loss by minimizing cable usage. In one embodiment, the modular energy storage system container (100) may be electrically and fluidly connected through joint surfaces between the blocks. In one embodiment, the modular energy storage system container (100) may include a block connecting member that directly connects external ports of a battery block (110) and an electrical block (130) via a quick connector. In one embodiment, an external port may refer to an integrated connection interface provided to support power and signal transmission between the modular energy storage system container (100) and the external environment, and the circulation of a cooling medium (e.g., the cooling medium may be coolant). In one embodiment, the block connecting member may allow power output from a plurality of battery blocks to be routed directly to the electrical block. In one embodiment, the modular energy storage system container (100) may include configurations for connecting a plurality of modular blocks. For example For example, the modular energy storage system container (100) may further include a semi-automatic twist lock for joining vertical corners between blocks and a C-shaped bracket for joining upper corners of horizontal joint surfaces between blocks, when the container does not include a common lower support structure (140) for connecting multiple modular blocks.For example, the semi-automatic twist lock and the C-shaped bracket may replace the lower support structure (140) to provide a direct connection structure for binding the shapes between blocks and supporting the load. In one embodiment, the semi-automatic twist lock may refer to a fixing device that physically restrains the corner castings of vertically adjacent blocks by connecting them when stacking the modular blocks according to the present disclosure vertically or fixing them to a transport vehicle. In one embodiment, the semi-automatic twist lock is inserted into an ISO standard corner casting hole and operates, and unlike a general manual method, it may have the following technical features. For example, during the process of placing the upper modular block onto the lower block or the common lower support structure (140), the internal spring or cam structure may operate due to the self-weight of the block, thereby automatically switching to a locking state without any separate manual operation. For example, when implementing an architecture by stacking 10-foot bi-con blocks in two or more layers, the semi-automatic twist locks located at the four corners of each block not only firmly support the vertical load between the blocks but also fundamentally prevent horizontal displacement caused by external vibrations such as pitching or rolling. For instance, given the characteristics of modular blocks, which are heavy objects containing high-density batteries, the semi-automatic twist locks allow for rapid fastening using only crane operations, without the need for a worker to climb onto the top of a high-positioned container to manually operate a handle. This significantly reduces on-site assembly time and can function as a safety aid to prevent the risk of personal injury associated with working at heights.For example, the semi-automatic twist lock is designed to allow the lock to be easily released from the ground using a provided wire or a dedicated tool when the stacking is released for system maintenance or block replacement, thereby supporting variable operation of the modular energy storage system container (100). Consequently, the semi-automatic twist lock may be a key fastening means for integrating standardized bi-cone modules into a single rigid structure. In one embodiment, the C-shaped bracket may refer to a support member having a 'C'-shaped cross section provided to reinforce the structural bonding of the modular block according to the present disclosure or to securely fix internal key components (e.g., cooling water pipes, cables, panels, etc.) to the frame. In one embodiment, the C-shaped bracket may be formed of high-strength steel or a corrosion-resistant alloy material and may be characterized by performing the following technical functions in implementing the architecture of the present disclosure. For example, when joining multiple modular blocks horizontally or vertically, C-shaped brackets can minimize assembly errors and provide structural integrity by fastening them in a way that wraps around the frame corners or joints of adjacent blocks. For example, C-shaped brackets can serve to restrain each block so that it maintains its designated position even in the event of external impact or vibration. For example, C-shaped brackets can function as edge brackets to fix and reinforce the edges of explosion-proof panels installed on the rear of battery blocks, enabling them to withstand high pressure during an explosion while maintaining a thin thickness of 15 mm or less. For example, C-shaped brackets can provide a shape optimized for preventing interference between blocks by firmly gripping the ends of panels while minimizing external protrusion. For example, C-shaped brackets can serve as guides to ensure that cooling water plumbing and DC cables placed inside the blocks are fixed without shaking.For example, a C-shaped bracket is applied to the fastening area between the enclosure panel and the main frame to increase the adhesion of the sealing material, thereby contributing to securing waterproof and dustproof performance of IP65 or higher required by electrical blocks, etc. For example, the C-shaped bracket may be a key fastening means that physically supports each modularized block to ensure independent durability, while simultaneously allowing the entire system to have rigidity as a single integrated container. In one embodiment, the explosion-proof panel may refer to a safety device that prevents explosions and chain fires in the system by rupturing or opening at a set pressure when the pressure inside the battery block rises rapidly due to thermal runaway of the battery module, etc., thereby safely discharging internal high-pressure gas and flames to the outside. For example, the explosion-proof panel is individually provided on one side (e.g., top, rear, front) of each battery block (110), so that even if an accident occurs in a specific battery block (110), it can block the transfer of flames to adjacent blocks or electrical blocks and independently relieve only the pressure of that block. For example, the explosion-proof panel is designed so that the panel unfolds upward upon explosion, thereby guiding flames and debris to be released into the air rather than onto the ground or adjacent equipment. This can serve to alleviate safety clearance requirements around the container installation site and ensure the safety of inspection personnel. In one embodiment, the battery block (110) may include rear wall-type explosion-proof panels that are individually installed on the rear of the battery block (110). For example, the rear wall-type explosion-proof panels are positioned on the rear of each battery block instead of the roof surface to allow for a stacked structure of two or more layers for multiple blocks, and may be configured to remain folded without protrusions under normal conditions, and to open upon explosion to discharge flames upward.In one embodiment, the rear wall-type explosion-proof panel is configured with a thickness to prevent structural interference during stacked assembly of a plurality of blocks, and is configured so that when opened by an explosion, the angle at which the explosion-proof panel opens is limited to a preset upward angle (e.g., 45 degrees), thereby reducing the required radius of the safety zone in the surrounding space. For example, if the opening angle of the explosion-proof panel is limited to 45 degrees or less, the trajectory of the flame and high-pressure gas ejected during an explosion may be guided steeply upward rather than horizontally. This allows for a significant reduction in the required radius of the legal and technical safety zone that must be secured at the rear of the system, which can lead to site efficiency that allows for more containers to be densely placed within a limited site. For example, when the panel opens within the gap between vertically stacked blocks, an angle of 45 degrees or less can prevent the panel body from physically colliding with the outer wall of the upper layer block or the protruding quick connector (103) area. For example, by limiting the opening angle, instantaneous impact torque applied to the hinge or tether wire can be dispersed. This prevents accidents where the panel completely detaches from the body and scatters, and allows the panel to maintain a constant angle even after pressure release and act as a guide to block secondary external ingress. For example, if the opening angle of the explosion-proof panel exceeds 45 degrees, as the opening angle exceeds 45 degrees and approaches the horizontal direction (90 degrees), flames and debris ejected from the inside can travel further parallel to the ground. This can cause direct damage to workers passing around the system or other adjacent facilities, and consequently, may impair space efficiency by forcing extensive safety clearances. For example, in a vertically stacked battery block structure, if a panel opens excessively beyond 45 degrees, the top of the panel may collide forcefully with the lower frame or piping structure of the block located directly above it.Such impact may cause structural deformation of the upper block where no accident occurred, or conversely, cause functional defects that make the discharge path incomplete as the panel itself is flung away. For example, if the panel is excessively open, the opening area after discharge is completely exposed to the outside, increasing the likelihood that firefighting water or external foreign substances may flow directly into the internal battery rack during the fire suppression process. This may carry the risk of inducing a secondary short circuit in surrounding battery cells in addition to the block where the accident occurred. For example, to fundamentally block physical interference between blocks when assembling multiple modular blocks by arranging them adjacently or stacking them vertically, the thickness of the explosion-proof panel (e.g., the thickness of the explosion-proof panel may be the thickness of the explosion-proof panel protruding outward when attached to a container) may be formed to be 15 mm or less. For example, by configuring the thickness of the explosion-proof panel to be 15 mm or less, a structure of complete contact between the outer walls of the blocks can be formed without the need to secure a separate gap when combining multiple battery blocks (110) in a horizontal or vertical direction. This can result in minimizing the overall installation area of ​​the system and enhancing structural integrity. For example, by designing the explosion-proof panel thickness to be 15mm or less so that it does not protrude outside the frame within ISO standard container specifications, damage to the panel from external impacts that may occur during crane operations or loading / unloading processes during maritime or land transport can be prevented, thereby maximizing transport stability. For example, by adopting a high-strength thin-film structure capable of withstanding high-pressure explosive forces even within a thin thickness, the explosion-proof panel thickness can be 15mm or less, allowing for the stable maintenance of an IP65 or higher sealing rating that effectively blocks the intrusion of external moisture or dust during normal operation.In one embodiment, the battery block (110) may include a detachable assembly panel applied to the left side to allow the initial loading of an internal battery and a double door that opens and closes applied to the front to allow maintenance. For example, external ports of the battery block (110), which are coupled with block connecting members for electrical and fluid connections between a plurality of blocks, may be positioned at the bottom of the front of the battery block (110) so as not to interfere with the opening space of the double door for maintenance. In one embodiment, when a common lower support structure (140) is provided, the common lower support structure (140) may include a first common lower support structure on which modular blocks are seated. For example, the first common sub-support structure may include a skid connection that directly electrically connects the first internal busbar for delivering power to blocks inside the container and the second internal busbar of the second common sub-support structure of another modular energy storage system container placed adjacent to the container. In one embodiment, power output from a power converter included in the electrical block (130) may be integrated through the first internal busbar, the skid connection, and the second internal busbar and output to the outside of the container and other containers that are not containers. In one embodiment, the modular energy storage system container (100) may include a single external connection port provided in the first common sub-support structure of the container, and the power integrated through the skid connection may be output to an external site power grid only through the single external port, so that individual site cabling work of other containers may be omitted under the combined structure of containers. In one embodiment, the external site power grid may receive power output from the container (100) of the present invention or supply power for charging the battery inside the container (100), of any form It includes external systems and may include the following examples depending on the installation environment and purpose.For example, the external site power grid may include a public power system, a renewable energy generation complex, an industrial and commercial microgrid, an electric vehicle fast charging station, and a multi-container parallel interconnection network. In one embodiment, the skid connection may connect the first common sub-support structure and the second common sub-support structure with a cable. For example, the skid connection may include a power cable made of a conductor used for power transmission over relatively long distances and wiring of complex paths, which is a structure in which a central circular conductor (stranded wire) is wrapped with an insulator and a sheath, and a flexible busbar having a structure in which thin copper or aluminum foil is laminated or fine wires are braided into a mesh. In one embodiment, the cable is a flexible cable that is a flexible line for transmitting power, and the skid connection includes quick connectors provided at both ends of the flexible cable, so as to be able to physically and electrically connect the first and second common lower support structures while absorbing vibration and assembly errors. In one embodiment, the skid connection can connect the first common lower support structure and the second common lower support structure with a flexible busbar. In one embodiment, the skid connection may further include a cable gland or busbar bushing that is coupled to a side hole of the first common lower support structure and the second common lower support structure through which the skid connection passes. In one embodiment, the cable gland may be a mechanism installed at the entry point of a cable penetrating the outer wall of a block or common lower support structure (140) to firmly secure the cable and maintain a seal at the penetration point. In one embodiment, the busbar bushing may refer to an insulating and sealing member that is coupled to a hole to maintain a seal when a skid connection connecting the first common lower support structure (140) and the second common lower support structure of the modular energy storage system container (100) penetrates a side hole of the structure.In one embodiment, the busbar bushing performs a purpose similar to that of a cable gland (400) but has a through structure corresponding to the shape of a busbar, which is a rigid conductor in the form of a plate or rod, and can perform the following technical functions in the present invention. In one embodiment, the cable gland or busbar bushing can perform waterproof and dustproof functions by maintaining the seal of the skid connection. In one embodiment, the first internal busbar is formed to extend along the longitudinal direction in the internal space of the first common lower support structure in place of a cable, thereby improving the space efficiency and electrical efficiency of the container. In one embodiment, the skid connection provides a hierarchical power routing structure between the container and another container, so that the first common lower support structure is directly electrically connected to the power converter of the electrical block mounted on top, and the second common lower support structure can be electrically connected to the power converter (PCS) of the electrical block via the first internal busbar through the skid connection. In one embodiment, the container and another modular energy storage system container are arranged adjacently to each other in the transverse direction, and the first common lower support structure and the second A common lower support structure can allow for the expansion of modular containers by forming a parallel connection structure in the transverse direction through a skid connection. In one embodiment, modular blocks are placed in a stacked structure on top of a first common lower support structure, and a plurality of battery blocks are arranged vertically in a plurality of layers on the first common lower support structure, and the battery power inside the stacked battery blocks is collected by a DC power control device provided at the bottom of the battery block of the bottom layer of the stacked structure and then routed horizontally toward a power conversion device of an electrical block. In one embodiment, the first internal busbar of the modular energy storage system container (100) can be embedded in the interior of the first common lower support structure in advance during the factory manufacturing process prior to installation at an external site.In one embodiment, the modular energy storage system container (100) may include a main power cable extending from an electrical block (130) located at the top or outside of the first common lower support structure. In one embodiment, the main power cable may be routed into the interior of the first common lower support structure so that power output from the electrical block (130) is directly electrically interfaced with the first internal busbar. In one embodiment, the modular energy storage system container (100) may include a cooling water plumbing path provided inside the first common lower support structure. For example, the first common lower support structure may be configured to share a cooling water piping path internally in parallel with a power connection path through the first internal busbar, thereby supplying cooling water supplied from the chiller block to each block inside the container in parallel. In one embodiment, at least one battery block (110) may include a plurality of battery blocks (110) that are vertically stacked, and the plurality of battery blocks (110) may be integrated and connected into a single space to jointly discharge the pressure in the event of an explosion. For example, a ceiling-type explosion-proof panel may be installed on the top ceiling of the integrated battery blocks to discharge explosion pressure and flames. In one embodiment, at least one battery block (110) may be provided in multiple units and assembled into a stacked structure that is vertically stacked. For example, each of the plurality of battery blocks (110) may have an independent explosion-proof structure for each block, including a rear-wall type explosion-proof panel individually placed on the rear wall of the block so that the design of the stacked structure can be made without interference.In one embodiment, when the modular energy storage system container (100) is equipped with the modular energy storage system container (100), power output from the battery block (110) is transmitted from the DC power control device to the first internal busbar embedded in the first common lower support structure sequentially through the power converter and fuse of the electrical block, and then output to the external site power grid sequentially through the skid connection and the second internal busbar. In one embodiment, the blocks constituting the modular energy storage system container (100) are based on 10-foot bi-con modules and can be combined in horizontal and vertical directions to support simultaneous expansion. For example, the blocks constituting the modular energy storage system container (100) may have dimensions of 2991 x 2438 x 2896 [mm]. In one embodiment, the common lower support structure may have dimensions of 9125 x 2438 x 945 [mm]. For example, common sub-support structures may be configured by vertically stacking three of them. In one embodiment, the modular energy storage system container (100) can individually optimize thermal, electrical, and structural performance according to climate conditions (e.g., desert, high temperature, cold region) and load patterns (e.g., 2, 4, 8 hours) through the separate design of the blocks. In one embodiment, the modular energy storage system container (100) can replace the chiller or AC block with a next-generation high-efficiency model, and can provide the effect that the installation method can be standardized by enabling replacement at the block level. In one embodiment, the modular energy storage system container (100) can provide standardized installation interfaces capable of establishing strategies. For example, the modular energy storage system container (100) can provide the effect of reducing mass production costs by manufacturing standardized piping, wiring, and structural connections between multiple blocks based on predefined specifications, enabling product configuration by combining blocks to meet customer needs, and supporting rapid delivery times.In one embodiment, the modular energy storage system container (100) may have an optimized layout structure according to the site conditions of the installation site. For example, the battery blocks (110) are basically arranged in a two-tier stacked structure, but can form a total three-tier stacked structure if a first common lower support structure (140) is included. For example, the blocks constituting each container are arranged back-to-back with a spacing of about 800 mm and can form a mutually parallel connection structure through skid connections. In one embodiment, each block may be combined into standardized units to maximize transport efficiency. For example, the battery block (110), electrical block (130), and chiller block (120) can be transported in 20-foot HC (High Cubic) units when two units are connected, and the common lower support structure (140) is configured to be transported in 30-foot HC units when three units are connected, thereby avoiding logistics weight limits. In one embodiment, for example, a Sunwoda 314Ah module is applied as a 3D model inside the battery block (110), thereby improving installation efficiency through a compact mounting space compared to the same capacity. In one embodiment, through the present invention, an energy density of approximately 450 kWh / m² per area can be secured when installing one set of containers. In one embodiment, to facilitate the smooth installation of the long-axis battery, the battery block (110) may adopt a structure in which the internal module is rotated 90 degrees. In this case, the left side of the battery block (110) may be provided with an assembly panel for initial loading, and the front may be provided with double doors for maintenance of the battery rack. For example, to prevent interference with the open space of the double doors, the cable and piping connection points may be positioned at the bottom of the front of the battery block (110). In one embodiment, the present disclosure may provide different design specifications depending on the installation infrastructure and explosion-proof requirements.For example, if the design specifications include a common lower support structure (140), the DC power control device (DCPM, 141) and the power converter (PCS, 142) can be placed inside the common lower support structure (140) to form an integrated control structure at the bottom of the container. And in the case of an explosion-proof structure, the stacked blocks can take a structure in which they share a ceiling-type explosion-proof panel at the top. For example, if the design specifications do not include a common lower support structure (140), the common lower support structure (140) can be excluded for system simplification, and the structure can be composed mainly of 10-foot blocks. In this case, the DC power control device (141) is embedded in the inner bottom of the battery block (110), and the power converter (142) can be installed individually inside the electrical block (130). To ensure explosion-proof performance, an independent rear wall-type explosion-proof panel (107) is applied to the rear wall of each battery block (110) to eliminate interference during stacking. For example, the chiller block (120) performs independent cooling water routing to the battery blocks (110) of each layer, and as the circulation and pressure stability of the piping in the first layer are ensured, uniform cooling can be supported without the installation of additional motors. In one embodiment, the connection between modular blocks can be made through cable glands (400) and conduit structures placed on the lower left / right sides of the box. For example, quick connectors (103) are applied to the power and piping interfaces to maintain a waterproof and dustproof rating of IP65 or higher at all times. For example, the high voltage (HV) connection part can be combined with a quick connector and a flexible cable (401) to ensure physical and electrical connection reliability even under conditions of vibration or assembly error. In one embodiment, the container (100A) or container system (100B) of the present disclosure may use dedicated block connecting members for vertical and horizontal connection.For example, vertical corner joints may use a semi-automatic twist lock utilizing the self-weight of the block, and structural integrity may be provided by applying a C-shaped bracket to the upper corner joint of the horizontal joint surface. In one embodiment, the disassembly process for replacing a specific block of the present disclosure may proceed in the order of disconnecting the power, disconnecting cables and piping via quick connectors, releasing the C-shaped bracket (104) and the semi-automatic twist lock (105), and lifting the block using a crane. According to the present disclosure, rapid replacement of parts is possible by removing only the block to be maintained or the block located above the block to be maintained, and the maintenance efficiency of the container can be maximized as there is no need to dismantle the entire system. The battery block (110) may include a plurality of battery racks and a DC power control unit (DCPM or BCU) inside. The DC power control unit (DCPM) may refer to a hardware control unit that monitors the charging and discharging status of the battery and switches the input and output of the DC power. In the case of an embodiment in which a common substructure (140; SKID) is excluded, the DCPM may be integrally fixedly mounted at the center of the inner bottom of the battery block (110). As an additional structural feature, the outer housing of the battery block (110) may be formed of steel or aluminum alloy material and may have a dual structure for maintenance and loading. Specifically, a bolt-fastened detachable assembly panel may be applied to the left side where the battery is first loaded, and a hinged double door may be mounted on the front side where routine maintenance is performed. Additionally, external ports for electrical / fluid connection with adjacent blocks may be concentrated at the bottom of the front of the battery block so as not to interfere with the opening trajectory of the double door.As a deflagration panel structure for explosion safety, a deflagration panel for discharging explosion pressure may be installed on the roof or rear wall of the battery block (110). For the optimization of the stacking structure, the deflagration panel may be formed as a rear wall type and normally maintain a folded state with a slim thickness of, for example, 15 mm or less, but may be mechanically restricted to unfold only at a specific angle (e.g., an upward 45-degree angle) around an open hinge when internal explosion pressure occurs. Through the block-embedded structure and slim rear explosion-proof panel structure of such DCPM, battery control is possible without a separate lower skid space, allowing energy density to be increased to a maximum per unit area (e.g., 450 kWh / m²), and by restricting the direction of flame discharge in the event of an explosion upward, the required radius of the safety area for surrounding facilities can be physically reduced by more than 50%. In an embodiment in which the common lower support structure (140) is excluded, the container (100A) may include a direct connection interface configuration for transferring fluid and power between heterogeneous blocks. The direct connection interface may include a cooling water plumbing routing structure between the chiller block (120) and the battery block (110), and a power routing structure between the electrical block (130) and the battery block (110). As a sub-concept and coupling method, the blocks may be coupled to each other via a quick connector, a cable gland, a flexible cable, and a bushing structure. For example, a quick connector may refer to a connection component in which male and female terminals are joined by a push-pull or twist-lock method without a separate tool. As for shape and material characteristics, a gland structure including a lock-nut made of high-quality polyamide (PA6) and a silicone gasket may be joined to the part penetrating the hole between the blocks.As a specific embodiment of pipe routing, when the battery block (110) is stacked in two layers, the first chiller pipe inside the chiller block (120) can be vertically raised and directly fed into the second-layer battery block, and the second chiller pipe can be horizontally moved and fed into the first-layer battery block in parallel. Through this flexible material-based quick connector and gland direct connection structure, mechanical assembly tolerances occurring during module stacking and micro-vibrations occurring during system operation can be absorbed, and high-grade waterproof or dustproof performance of IP65 or higher can be achieved at the joints, thereby minimizing the risk of system shutdown due to leakage and short circuits. In addition, through independent pipe routing for each layer, uniform cooling water circulation is possible even in a two-layer structure without the installation of additional hydraulic pumps, resulting in a technical effect of reducing cooling drive power. In one embodiment, the container (100A) or container system (100B) of the present disclosure may include a base network structure (e.g., 140) that supports the blocks integrally from below and simultaneously electrically connects other container units. Containers (100A and 100B) may include a first common lower support structure (SKID, 140) on which a battery block (110), a chiller block (120), and an electrical block (130) are seated. As illustrated in 100B of FIG. 1, the first common lower support structure (140) may be continuously extended and connected in parallel through a skid connection with a second common lower support structure of another container unit arranged adjacently to the side. In the internal empty space of the first common lower support structure (140), a first internal busbar made of, for example, highly conductive copper (Cu) or aluminum (Al) material that replaces cables may be pre-installed along the length during the factory assembly stage.As various embodiments of the connection relationship, the skid connection may include at least one of the following methods: connecting the first common lower support structure (140) and the second lower support structure with a high-capacity flexible cable, connecting with a flexible busbar, or connecting with a rigid joint fitting. As a power transfer sequence, direct current power released from the battery may be sequentially transmitted and routed from the DCPM of the battery block (110) through the PCS and fuse of the electrical block to the first internal busbar and skid connection within the common lower support structure (140), and then to the second internal busbar. By embedding the busbar inside the common lower support structure (140) and establishing a parallel connection topology between the skids in this manner, the entire power can be transmitted and received only through a single external connection port (terminal) located at one end of the expandable system (100B) when connected to an external substation (MV station). This provides a powerful technical effect that drastically reduces on-site cabling and construction costs by overcoming the conventional physical labor-intensive limitations of having to individually run hundreds of high-power cables into each container when constructing large-scale sites such as power plants. In an embodiment where the common lower support structure (140) is excluded, direct connections based on quick connectors and glands can be implemented. Accordingly, electrical lines and / or fluid lines are directly connected at the joint surface between blocks without a medium called a skid (140), and flexible cables and, for example, IP65 rated quick connectors and / or glands can be used to absorb errors and vibrations that occur at this time. In an embodiment where the common lower support structure (140) is excluded, a pump-free two-layer independent piping routing structure can be utilized. Since there is no skid (140) to concentrate chiller piping at the bottom, the left chiller is routed individually to the upper battery block and the right chiller to the lower battery block, so that water pressure problems can be resolved without additional motors or pumps.In the case of embodiments where a common sub-support structure (SKID) is excluded, the present disclosure may include physical direct coupling devices that self-support the load between blocks and fix their shape. The physical direct coupling devices may include a twistlock for fastening the corners of blocks stacked vertically and a bracket member for fastening the corners of blocks that meet horizontally. The twistlock may utilize a semi-automatic twistlock mechanism in which a pin of the coupling part rotates to automatically induce fastening when blocks are lowered and fed in via a crane. The bracket member may include a structure in which both ends of a steel C-shaped bracket are inserted into the upper corner (casting corner) holes of two horizontally adjacent blocks and secured with a locking pin. By applying a modular direct connection architecture based on such semi-automatic twistlocks and C-shaped brackets, a skid-less structure can be achieved by completely removing the steel skid frame, which occupies heavy weight and volume, from the system. Accordingly, mechanical structural effects can be achieved, such as reducing the overall weight of the container, avoiding constraints on container cargo transport, simplifying crane lifting operations at the site, and maximizing intuitive modular stacking scalability like modular block assembly. FIG. 2 exemplarily illustrates the connection between blocks constituting a modular energy storage system container according to one embodiment of the present disclosure. For example, FIG. 2 illustrates an exploded view of the assembly of multiple blocks and a common lower support structure of a modular energy storage system container according to one embodiment of the present disclosure. The container of the present disclosure may include a combined form of modules configured to have individual housings by dividing functions into multiple parts according to purpose.A plurality of modular blocks may include at least one battery block (110) containing a battery rack and a DC power control device inside, a chiller block (120) that generates and circulates cooling water, and an electrical block (130) that includes a power converter. The battery block (110) may be a cubic structure of the smallest unit that physically stores power. The battery rack included in the battery block (110) may be hardware in the form of a physical shelf in which a plurality of battery cells or battery modules are loaded in series and parallel. The DC power control device may be a hardware control panel (e.g., BCU, etc.) that switches the DC power input and output of the battery and protects against overcurrent. The chiller block (120) may be a structure dedicated to thermal management for controlling the heat generated by the battery, including a compressor, a condenser, etc. The electrical block (130) may be a structure dedicated to power management that converts DC and AC and performs power system control. The power converter may be a power electronics-based hardware inverter that converts direct current power into alternating current power for transmission to the power grid. The present disclosure may include mechanical direct coupling devices for physically binding the shapes between blocks and self-supporting shaking or external loads. The direct coupling devices may include a semi-automatic twist lock that joins the corners meeting in the vertical direction and a C-shaped bracket that joins the corners meeting in the horizontal direction. The semi-automatic twist lock may be a spring-based locking hardware in which an internal pin mechanically rotates to automatically engage the casting corners of the upper and lower blocks when the upper block is lowered via crane lifting. The C-shaped bracket may be a physical clamp structure made of high-strength steel material in which both ends are inserted into holes on the upper joint surfaces of two blocks arranged horizontally adjacently to fix the lateral separation.As shown in the enlarged view 101B of FIG. 2(a), the fastening components can be applied to corner connections between battery blocks (110) or between battery blocks (110) and chiller blocks (120). In various modified embodiments, the fastening devices may be replaced by or used in conjunction with any one of a manually operated twist lock, a hexagonal bolt-nut assembly, a magnetic locking member, or a side-sliding fastening member. By applying a physical direct connection structure based on such a semi-automatic twist lock and C-shaped bracket, the block can withstand external vibration loads, such as typhoons or earthquakes, solely through the rigidity of the block itself, even under a skid-less structure in which the lower skid, which served as a heavy steel frame, is excluded. In addition, this allows for the vertical separation of only the block in the corresponding row that failed to a lower block (e.g., a first-floor battery block) using a crane without dismantling the entire system, while leaving the adjacent blocks intact, thereby improving mechanical structural performance by enhancing equipment maintenance accessibility and reducing work time. The present disclosure may include a direct connection interface configuration that does not pass through an intermediate medium (e.g., a skid) to transfer cooling fluid and high power between spatially separated heterogeneous blocks. The direct connection interface may be a plurality of block connecting members (101) provided between the connecting surfaces of the battery block (110), electrical block (130), and chiller block (120). The block connecting member (101) may include an external port (102) and a quick connector (103) structure that mediates it. The connecting surface may be a metal outer wall housing surface that physically faces the different modular blocks when assembled. The external port (102) may allow a cable or pipe to protrude or be drawn in from the outside of the block housing to allow physical input or output of power or fluid. The block connecting member (101) may refer to an assembly that electrically and fluidly penetrates and conducts power to each other between separated blocks.The quick connector (103) may be a connection component having high current or high pressure resistance performance, in which male and female terminals are connected by a push-pull method or a rotary snap connection method without the operation of a separate hand tool wrench. The cable gland may be a bushing component that hermetically seals the gap of the hole through which the cable passes through the port, and the gasket and lock-nut may be a fixing and waterproof ring made of silicone or polyamide (PA6) material that strengthens the seal of the gland. As shown in the enlarged view 101A of FIG. 2 (a), the external port (102) at the bottom of the battery block (110) and the port of the adjacent block may be directly connected in a horizontal direction via a flexible cable having quick connectors (103) provided at both ends. As an example of fluid routing, when a left chiller and a right chiller are provided inside a chiller block (120), the cooling pipe of the left chiller is directly vertically routed to the upper (e.g., 2nd floor) battery block (110), and the cooling pipe of the right chiller is directly horizontally routed to the lower (e.g., 1st floor) battery block (110) so that a fluid connection can be established. As an example of power routing, power generated from the battery may have a sequence in which it passes through a block connecting member (101), sequentially through a DC power control device (DCPM), a power conversion device (PCS), and a fuse, and then output to an external site. By applying direct routing using such flexible material-based cables and quick connectors (103), mechanical assembly errors of several millimeters that occur during stacking between container modules and micro-vibrations during container operation can be absorbed. Furthermore, through the cable gland structure of the connection joint surface, high-reliability dustproof and waterproof performance of, for example, IP65 grade or higher can be implemented in hardware.This reduces the critical shutdown rate of the entire system due to dust ingress, short circuits, and water leakage, and allows for the stable parallel distribution of cooling water to the two-layer battery without an additional hydraulic pump. Accordingly, an excellent performance improvement effect can be provided, which reduces the operating power within the container. Referring to FIG. 2(a), the modular block of the present disclosure may include a block connecting member (101A) that can form a physical or electrical connection with another modular block adjacent to the modular block, for example, at least one corner of the eight corners of the block. For example, the block connecting member (101A) may form a left-right and / or up-down connection of the modular blocks. In one embodiment, the block connecting member (101A) may include an external port (102) corresponding to a female member having a receiving space inside the block connecting member (101A) and a quick connector (103) corresponding to a male member inserted into the receiving space. For example, the external port (102) includes a casting hole that is an ISO standard container specification, so that the quick connector (103) can form an immediate physical connection and electrical conduction state with only a simple insertion or rotational motion without a separate tool. For example, the external port (102) may have at least one side of the front, left or right side and the front open to enable insertion of the quick connector (103). For example, the quick connector (103) may be configured for left-right connection and / or up-down connection. For example, if the quick connector (103) is for left-right connection, the quick connector (103) may have a left-right protruding housing structure suitable for joining by approaching from the side when a plurality of blocks are arranged horizontally in parallel. For example, if the quick connector (103) is for left-right connection, the quick connector (103) may include a cylindrical or rectangular body that protrudes a certain length outward from the side panel of the block, and may have a locking lever or a rotating sleeve with a threaded structure formed on its outer surface so that it is easy for a worker to grip and operate with their hand.For example, if the quick connector (103) is for vertical connection, the quick connector (103) may have an embedded and guide cone structure that induces a natural connection without being damaged by the load of the upper block during vertical stacking of the modular blocks. For example, it may have a flat base structure that is seated parallel to the upper surface of the lower block or the lower surface of the upper block, and may be positioned lower than the panel surface or embedded inside the protective frame so that the connector does not become a direct load support point during stacking. In one embodiment, referring to FIG. 2(b), various combinations of modular blocks connected using a block connecting member (101) are disclosed. For example, when two modular blocks are connected, the various combinations of modular blocks may include a combination of a battery block (110) and a battery block (110), a combination of a battery block (110) and a chiller block (120), and a combination of a battery block (110) and an electrical block (130). For example, when two or more modular blocks are connected, various combinations of modular blocks may include a connection of three battery blocks (110), a combination of one battery block (110), one chiller block (120), and one electrical block (130), a combination of two battery blocks (110) and one chiller block (120), a combination of two battery blocks (110) and one electrical block (130), etc. Various combinations of modular blocks are not limited to the examples listed. As illustrated in FIG. 2(b), the battery blocks (110) may be stacked vertically in two or more layers, and the electrical blocks (130) and chiller blocks (120) may be arranged in a longitudinal or transverse direction on the side of the battery blocks (110). As another variant embodiment, each block may be manufactured in 10-foot (ft) bi-con dimensions and configured so that two blocks are combined to be transported in a 20-foot high-cubic container, or three blocks are combined to be transported in the form of a 30-foot high-cubic container.By applying a structure of functional block division and 10-foot stacking to the system, it is possible to fundamentally avoid cargo weight restrictions during container ship transport, even when the interior is fully loaded with heavy batteries. Furthermore, this allows for the free combination and upgrading of the cooling and electrical blocks to match the climate of the installation site (e.g., desert, cold region) or power load patterns, thereby generating a technical effect that maximizes the design flexibility and lifecycle efficiency of the entire hardware system. In one embodiment, referring to FIG. 2(c), connections of common lower support structures (140) may be included. In one embodiment, the common lower support structure (140) may include a block connecting member (101) that enables left-right and / or up-down connection of a plurality of common lower support structures (140). For example, a plurality of common lower support structures (140) may be connected left-right to form a single layer. Additionally, multiple common lower support structures (140) forming a single layer may be connected vertically using block connecting members (101B) and stacked in multiple numbers to form a combination of common lower support structures (140). Embodiments of the present disclosure may include a common lower support structure (140) that is located at the bottom and supports the entire integrated load of the upper blocks, while simultaneously operating as a base power network structure for electrically connecting other external container units in parallel. The structure (140) may be arranged in multiple numbers as shown in FIG. 2 (c) and (d), and a battery block (110), a chiller block (120), and an electrical block (130) may be placed on top. The common lower support structure (140) may be a steel skid frame at the base that distributes and supports the load of the entire container.The internal busbar may be a thick rod-shaped conductor made of highly conductive aluminum (Al) or copper (Cu) material that is embedded along the length of the internal empty space of the common lower support structure (140) in place of an insulated cable. The skid connection may be a power connection mechanism that electrically integrates the end of the internal busbar with the end of the busbar of an adjacent structure. The skid connection may enable electrical connection between containers. As shown in FIG. 2 (c), the first common lower support structure (140) may be connected in parallel in the lateral direction through the skid connection with the second common lower support structure (140) positioned on the side. Power output from the power converter (pcs) inside the electrical block (130) is drawn in from the top to the bottom through the main power cable and interfaces with the busbar of the first common lower support structure (140), and may be sequentially routed to the second busbar of another container through the skid connection. As various modified embodiments, the skid connection may have a gland connection structure based on a high-capacity flexible cable, or may include a busbar bushing connection method that assembles a flexible busbar terminal. In this way, by pre-installing a high-capacity busbar inside the common lower support structure (140) at the factory stage and applying a transverse parallel expansion structure based thereon, the container(s) at an external power plant site where multiple modular containers are deployed on a large scale can transmit and receive to and from the entire power grid through only a single external connection port (terminal) at one end.This overcomes the physical limitations of the conventional labor-intensive process, in which dozens to hundreds of strands of site power cables had to be individually pulled in and connected to each container during power plant construction, thereby generating a power topology optimization effect that innovatively reduces the cost of expensive high-power cable materials, electrical construction labor costs, and work time required for on-site construction by more than 80%. In one embodiment, referring to FIG. 2(d), an example is disclosed in which a plurality of common lower support structures (140) are stacked by connecting left and right and up and down using block connecting members (101). For example, three common lower support structures (140) can be connected left and right to form a single layer. In addition, a combination of three common lower support structures (140) in a layer of three common lower support structures (140) and three common lower support structures (140) connected vertically to form a total of nine common lower support structures (140) may be illustrated. The container of the present disclosure may include a safety venting structure for safely venting outwardly the explosive pressure generated in the event of abnormal thermal runaway of the battery cell and internal fire. The safety venting structure may include a top explosion-proof panel structure placed on the top roof surface of the container, or a side (rear) explosion-proof panel structure (107) installed individually on the rear wall of each block instead of the roof surface. The explosion-proof panel may be a disaster safety defense component that, when the internal pressure of the module reaches a preset critical pressure (e.g., 25 to 100 mbar), the physical panel structure is destroyed or pops up around a hinge to forcibly vent flames and high-pressure gas to the outside. In the case where the module of the container is composed of a single layer or has no additional stacking, an upper explosion-proof panel (106) is applied so that two battery blocks (110) can be combined into one single space to jointly discharge pressure to the ceiling.As an alternative embodiment, in a structure requiring a vertical stacking design of two or more layers for multiple blocks, a rear explosion-proof panel that is individually divided into a wall-like shape instead of a roof may be applied. In this case, the rear explosion-proof panel (107) may be mechanically configured to maintain a folded, thin state of, for example, 15 mm or less, so that there are no external protrusions in normal conditions. This structure of an individually divided and slim rear explosion-proof panel (107) can maximize the vertical space density of the container by eliminating the mechanical panel interference problem that inevitably occurs between upper and lower blocks when modules are stacked vertically. In particular, by designing the hinge to be mechanically limited so that the opening angle when the panel is opened by an explosion is only at a specific angle, such as, for example, 45 degrees upward, the explosion flame can be prevented from spreading widely in the horizontal direction. This can achieve excellent fire safety performance enhancement effects, such as preventing fire spread to opposite equipment even in environments with a narrow rear maintenance gap of, for example, 800 mm, and reducing the physical required radius area of ​​the safety zone for container installation by, for example, more than 50%. FIG. 3 is a diagram illustrating various block connection structures constituting a modular energy storage system container according to one embodiment of the present disclosure. In one embodiment, various combinations of the number of modular energy storage system containers (100) are disclosed. For example, if the modular energy storage system container (100) includes six modular blocks and three modular blocks in the modular energy storage system container (100) form a single layer, resulting in a total of two layers, at least one modular block may be replaced. For example, when at least one modular block is replaced, at least one modular block may be removed by moving upward or left / right, and the modular block to be replaced in the removed place may be replaced by moving downward or left / right.In one embodiment, referring to FIG. 3(a), the modular energy storage system container (100) may be composed of four battery blocks (110), one chiller block (120), and one electrical block (130). For example, when one battery block (110) located in the center of the second floor is replaced, the battery block (110) being replaced may be removed from the modular energy storage system container (100) by moving in direction A. In one embodiment, referring to FIG. 3(b), when one battery block (110) located in the center of the second floor is replaced, the block connecting member (104) for horizontal connection of the battery block (110) being replaced may be moved in direction B to be connected left and right. In one embodiment, referring to FIG. 3(c), when one battery block (110) located in the center of the second floor is replaced, the block connecting member (101) for vertical connection of the battery block (110) can be moved in direction C to be connected vertically. In one embodiment, the direction in which the modular block is removed and replaced and connected is not limited to directions A, B, and C. In one embodiment, the block connecting member (101) for horizontal connection of the present disclosure may be a C-shaped bracket. In one embodiment, the C-shaped bracket may perform the function of preventing the gap between the blocks from widening or a step difference from occurring by gripping the joint frame of each of the two modular blocks arranged side by side in a horizontal direction from the outside. For example, the C-shaped bracket may be formed of a high-strength metal material so as to firmly maintain the alignment state between the blocks even in the event of external vibration or ground subsidence. For example, when two blocks are arranged in close horizontal contact, the C-shaped bracket may connect the side vertical frame ends of the two blocks together. For example, by applying a compressive force through a fastening bolt or wedge structure provided on the inner side of the bracket, the airtight gasket between the blocks is compressed, thereby simultaneously ensuring waterproof performance at the horizontal connection.In one embodiment, the block connecting member (105) for vertical connection of the present disclosure may be a semi-automatic twist lock. In one embodiment, the semi-automatic twist lock is inserted into the casting hole of an external port and operates, and may have a mechanism that switches to a locked state by the weight of the block without separate manual operation during the process of placing the upper block on top of the lower block. This can significantly increase the work speed during vertical stacking and ensure the safety of workers at height. For example, when a modular energy storage system container (100) stacks another battery block in two layers on top of a battery block, the semi-automatic twist lock is pre-mounted on the four upper corners of the lower block, and then when a crane lowers the upper block and the casting part of the external port comes into contact with the twist lock, an internal spring cam device rotates to integrate the upper and lower blocks. Through this, the modular energy storage system container (100) can have strong mechanical restraint so that the upper block does not detach or overturn even under strong winds or seismic loads. The container of the present disclosure may include a vertical hardware coupling device to suppress vertical movement between modules stacked vertically and to firmly support the load. As shown in the enlarged view according to FIG. 3 (c), the vertical hardware coupling device may be a semi-automatic twist lock (105) that mutually fastens the opposing vertical corners of blocks (110, 120, 130) stacked vertically. The semi-automatic twist lock (105) may be a fastening component made of a high-strength alloy material that is inserted into a casting corner groove formed at each corner of the block, and when the upper block is lowered and settled via a crane, an internal spring and metal pin mechanically rotate automatically to physically lock the upper and lower blocks. The semi-automatic twist lock (105) can be used for fastening between the first and second layers of the battery blocks (110), and can be applied in the same way to vertical fastening between the chiller blocks (120) and the electrical blocks (130).As another variant embodiment, the vertical hardware coupling device may be replaced by or used in parallel with any one of a manual twist lock in which a worker directly turns a lever, a hexagonal bolt and nut fastening assembly, or a hydraulic sliding pin coupling device. By applying a vertical direct connection structure based on such a semi-automatic twist lock (105), the vertical coupling rigidity between upper and lower blocks can be increased beyond external loads even under a structure in which a separate thick steel skid frame is omitted. During on-site installation, the vertical alignment and locking processes are performed together by only crane lifting and seating, thereby achieving an improvement in mechanical structural performance that reduces the manpower and assembly time required for construction. The container of the present disclosure may include a transverse hardware coupling device to prevent lateral spreading between heterogeneous or homogeneous modules arranged horizontally adjacently and to maintain lateral rigidity. As shown in the enlarged view of FIG. 3(b), the transverse coupling device may be a C-shaped bracket (104) that connects the upper corners of the joint surfaces of blocks that meet in the transverse direction. The C-shaped bracket (104) is a bridge-type clamp structure having the shape of the letter C, and may be a physical member made of steel or special steel material in which protrusions at both ends are forcibly inserted into the upper surface holes of the upper casting corners of two blocks placed side by side to fix the horizontal gap between the blocks. The C-shaped bracket (104) may be positioned to connect the upper corners between the first battery block (110) and the second battery block (110), or to cross and connect the upper corners where the battery block (110) and the chiller block (120) meet. As a modified embodiment, to additionally support a horizontal load, the C-shaped bracket (104) may be symmetrically additionally fastened to the lower corners as well as the upper corners, or a steel pin for horizontal fastening penetrating the side holes may be additionally connected.By fastening a C-shaped bracket (104) made of such steel material to the uppermost joint surface of the block, structural twisting phenomena such as the individual blocks divided into 10-foot units detaching laterally or gaps opening up can be prevented even when strong external lateral shear loads, such as seismic vibrations or typhoons, occur. Accordingly, an effect of improving hardware safety can be provided to protect against damage to flexible cables and piping introduced into the container (100) and to increase the seismic design durability of the container (100). The container of the present disclosure may include a structural selective maintenance method to prevent the shutdown and complete dismantling of the entire system in the event of a failure of a specific individual device among a plurality of stacked block hardware. This maintenance method may be a mechanism that separates only the target block by individually releasing the mechanical fastening of the semi-automatic twist lock (105) and the C-shaped bracket (104) only in the failed column. As shown in FIG. 3, if a defect occurs in a specific battery block (110) located in the center of the first floor while the system is assembled in three rows on two floors, the system power can be cut off first, and the cables and piping based on the external port side quick connector connected to the bottom of the block can be physically separated. Afterward, the C-shaped bracket (104) connected to the top of the target block is removed, and the handle of the semi-automatic twist lock (105) is rotated to release the connection. Then, without dismantling the other blocks in the adjacent left and right rows, the upper second-floor battery block of that row is lifted first using a crane, and then only the target first-floor battery block is lifted vertically upward, thereby allowing the battery block to be independently removed from the container. This modular selective removal method can be applied in the same mechanical sequence when replacing (upgrading) the chiller block (120) or electrical block (130) with a next-generation high-efficiency model, as well as the battery block (110).According to one embodiment of the present disclosure, a first embodiment may be applied in which a common lower support structure is installed at the bottom of the blocks to support the load of the entire system and to route power in parallel. As another embodiment, a second embodiment may be applied in which the entire shape is maintained solely by load support between the blocks and direct connection of the joint surfaces with the common lower support structure excluded. FIG. 4 is a drawing for explaining explosion-proof panels provided in a modular energy storage system container according to one embodiment of the present disclosure. Through FIG. 4 (a) and (b), the arrangement structure of the top explosion-proof panel (106) and the side explosion-proof panel (106) of a modular energy storage system container (100) according to one embodiment of the present disclosure is illustrated for comparison. In one embodiment, referring to FIG. 4 (a), the modular energy storage system container (100) may include at least one top explosion-proof panel (106). For example, if the modular energy storage system container (100) is in the form of three modular blocks each stacked in two layers, the battery modules provided at the top may include a top explosion-proof panel (106) on the top of the battery modules. In one embodiment, referring to FIG. 4(b), the modular energy storage system container (100) may include at least one side explosion-proof panel (107). For example, if the modular energy storage system container (100) is in the form of three modular blocks each stacked in two layers, the battery modules provided at the top may include a side explosion-proof panel (107) on the rear of the battery modules. In one embodiment, the modular energy storage system container (100) may include at least one side explosion-proof panel (107) on the top and / or rear of the battery modules. In one embodiment, the explosion-proof panel to which the present disclosure applies may be a rupture membrane type panel.For example, a rupture-membrane type panel is a panel made of a high-strength thin-film material designed to rupture at a specific critical pressure. Its simple structure and extremely thin thickness make it easy to satisfy the protrusion limit of 15 mm or less of the present disclosure. This allows the panel itself to rupture and form an immediate discharge path when the pressure inside the battery block rises rapidly. In one embodiment, the explosion-proof panel applied to the present disclosure may be a hinged relief type panel. For example, a hinged relief panel may be in a form where one side of the panel is connected to an enclosure frame with a hinged structure. For example, a hinged relief panel normally remains closed by a locking device, and when internal explosion pressure occurs, the locking part is released, allowing the panel to unfold outward. For example, a hinged open panel may be designed to open upwards and take on a form optimized for upward-guided exhaust, which directs the direction of flame exhaust upwards. In one embodiment, the explosion-proof panel to which this disclosure applies may be a spring / shear bolt type panel. For example, the spring / shear bolt type panel may maintain a closed state by utilizing a mechanical fastening force (e.g., spring pressure or the breaking strength of the shear bolt). For example, the spring / shear bolt type panel may have a structure in which, when a pressure exceeding a set pressure is applied, the fastening member breaks or the spring is compressed, causing the entire panel to be pushed outward to relieve the pressure. In one embodiment, the explosion-proof panel may be attached in the following manner to prevent interference during the stacking of modular blocks and to maintain airtightness at all times. In one embodiment, the attachment method of the explosion-proof panel may be a flush mounting.For example, in a flush mounting method, the main body and fastening frame of the explosion-proof panel may be recessed inward from the rear outer wall panel surface of the battery block, or the external protrusion may be 15 mm or less. For example, the flush mounting method may be characterized by preventing physical collisions or assembly errors caused by panel protrusions even when multiple blocks are stacked in close contact horizontally or vertically. In one embodiment, the attachment method of the explosion-proof panel may be a sealing gasket and clamping. For example, in the sealing gasket and clamping method, a gasket made of high-elasticity rubber or silicone material is interposed at the bonding interface between the panel and the block body, and the explosion-proof panel can be clamped and attached with a certain pressure by a C-shaped bracket or a retainer frame. This attachment method can guarantee a waterproof and dustproof rating of IP65 or higher in a sealed environment where an internal dehumidifier and heat exchanger are operated. In one embodiment, the attachment method of the explosion-proof panel may be anti-fragmentation tethering. For example, the anti-flying tethering method may be attached to the main body frame in a physically restrained state via high-strength wires or tethers to prevent panel fragments from flying far outward and causing damage to surrounding facilities or personnel when the panel is opened or ruptured by pressure. In one embodiment, the attachment method of the explosion-proof panel may be a shear pin-based precision attachment. For example, in a shear pin-based precision attachment method, the four corners of the panel are fixed with precisely designed shear pins or shear bolts, forming an attachment structure such that all fastening parts break simultaneously as soon as the internal pressure reaches a reference value (e.g., 0.1 to 0.5 bar), allowing the panel to open without delay. In one embodiment, the explosion-proof panel may be a safety defense component made of stainless steel that mechanically opens the physical panel structure to forcibly discharge explosive force when the internal pressure reaches a preset threshold, for example, 25 to 100 mbar.As a modified embodiment, the explosion-proof structure can be independently applied to both an embodiment environment in which blocks are stacked on a common lower support structure (skid) and an embodiment environment in which blocks are directly connected by their own weight without a lower skid. By applying this explosion-proof panel structure to a modular container, the pressure inside the sealed container can be immediately relieved even in the event of an unexpected chain explosion of battery cells, thereby preventing catastrophic mechanical damage such as the rupture or collapse of the entire housing. Additionally, this can achieve an enhanced durability effect that confines explosion damage to the block in question and prevents the disaster from spreading to surrounding high-value electrical components or other systems. The present disclosure may include an integrated safety venting structure for hydrodynamically linking multiple battery storage spaces to centrally discharge explosion pressure. As a middle concept, as illustrated in FIG. 4(a), the integrated safety venting structure may be an upper explosion-proof panel (106) installed on the uppermost ceiling (roof) surface of multiple stacked battery blocks. As a definition of the terms in the claim and as a hardware configuration, the upper explosion-proof panel (106) may be a large-area roof-type pressure relief mechanism that is bolted to cover a perforated area of ​​the roof surface and includes a silicon gasket for airtightness. As a variation of the sub-concept and spatial combination, when a stacked structure is applied, multiple battery blocks stacked vertically may be integrated and connected into a single space (1 room) where the internal pressure is shared by opening the inter-layer partitions. As another additional variation, the upper explosion-proof panel (106) may be configured in at least one of the following: a bursting foam form in which the entire panel breaks the rupture pin and completely separates and flies vertically upward upon pressure rise, or a door form that opens pop-up around one side hinge.By adopting this single-space (1 room) integration and ceiling-mounted top explosion-proof panel (106) structure as hardware, the discharge area can be maximized in the upward direction where the strongest pressure is concentrated during an explosion, thereby dramatically increasing the gas discharge speed. Additionally, since there is no need to attach a separate explosion-proof device to each floor, the structural simplicity of the system's exterior can be ensured, and the mechanical design optimization effect of reducing panel component costs and assembly labor can be provided. The container of the present disclosure may include an independent split safety venting structure to control explosion pressure on an individual module basis, while eliminating physical interference between modules so that modules can be stacked vertically. As illustrated in FIG. 4(b), the independent split safety venting structure may be a side explosion-proof panel (107) structure that is individually placed on the rear wall of each of the plurality of battery blocks instead of a roof surface. The side explosion-proof panel (107, or rear wall-type explosion-proof panel) may be a wall-type explosion vent designed to open when the container is installed in a rear-mounted structure. In order to stack multiple blocks in two or more layers according to the modular container structure, the side explosion-proof panel (107) may be configured to remain in a folded state, adhering closely to the housing wall with an ultra-slim thickness of, for example, less than 15 mm, so that no external protrusion occurs under normal circumstances. As a modified embodiment, since the risk of explosion is relatively low in the case of the full-length block, the rear cable entry port may be placed instead of the side explosion-proof panel (107), thereby diversifying the functional utilization of the space. As this individual split-type and slim-type side explosion-proof panel (107) structure is applied to the modular container, the problem of mechanical assembly interference of the explosion-proof mechanism, which inevitably occurs between upper and lower blocks when stacking modules in the vertical direction, can be resolved.Accordingly, the vertical space density of the container can be maximized regardless of the presence or absence of a lower skid, and individual separation can be allowed without damaging the explosion-proof structure of other blocks even during future independent maintenance of the lower battery block. The container of the present disclosure may include an angle limiting mechanism to prevent secondary disaster transmission to adjacent facilities by mechanically controlling the directionality of flames ejected outward in the event of a fire and explosion. The angle limiting mechanism may be a hinge limiting structure that controls the physical trajectory of opening when the side explosion-proof panel (107) is opened by an internal explosion. The opening angle refers to the maximum angle of development formed relative to the outer wall of the container when the panel is pushed out, and may be physically limited, for example, through steel supports or wire ropes. As a modified embodiment, the side explosion-proof panel (107) may be mechanically limited so that it does not completely detach upon explosion but opens around a bottom or top hinge, while the direction of flame ejection is developed only up to, for example, an upward angle of 45 degrees. As a modified embodiment, under a rear-mounted structure in which modular containers face each other's rears, the upward flame exhaust mechanism can form a safe trajectory so that flames do not reach the opposite equipment even in an extremely narrow environment where the maintenance gap between the two containers is, for example, only 800 mm. As this upward (e.g., 45 degrees) opening angle limiting mechanism is implemented in hardware, the fatal radiation phenomenon of an explosion flame spreading widely in the horizontal direction can be blocked. FIG. 5 is a drawing for illustrating piping and cable connections within a modular energy storage system container according to one embodiment of the present disclosure. In one embodiment, referring to FIG. 5, the modular energy storage system container (100) may include cooling water piping (200) and power cables (300).An enlarged exploded view illustrating the connection interface and airtight structure between heterogeneous blocks of a modular energy storage system container is illustrated in FIG. 5. The container of the present disclosure may include a direct connection interface configuration for transferring cooling fluid and high-capacity power between spatially separated heterogeneous or homogeneous hardware modules. The direct connection interface may include a block connecting member (101) and an external port (102) that mediate electrical and fluid conduction between a battery block (110), a chiller block (120), an electrical block (130), and a common lower support structure (140). In one embodiment, the block connecting member (101) may refer to an integral connection assembly that connects modules (e.g., blocks) inside the container by penetrating the outer wall of the housing of the separated physical blocks. A direct connection interface may be implemented using the block connecting member (101). In the present disclosure, a direct connection interface may refer to a connection and routing structure in which electrical and fluid are directly transmitted and received through a joint surface in which spatially divided heterogeneous blocks meet in a horizontal or vertical direction without passing through an intermediate bypass medium such as a common lower support structure. A block connecting member (101) may refer to a hardware connection component or a collection of components mounted on the outer wall (e.g., joint surface) of a block to physically implement the direct connection interface. In one embodiment, the block connecting member (101) may implement connections between cables and / or connections between pipes. In one embodiment, the block connecting member (101A) may correspond to a cooling water pipe (200) or include at least a portion of a cooling water pipe (200A). For example, if the block connecting member (101A) corresponds to a cooling water pipe (200) or includes at least a part of the cooling water pipe (200), the block connecting member (101A) may be a combination of a cooling water pipe (female) (200A) and a cooling water pipe (male) (200B).For example, if the block connecting member (101) is a combination of a cooling water pipe (female) (200A) and a cooling water pipe (male) (200B), a plurality of containers (100) may be connected by the combination of the cooling water pipe (female) (200A) and the cooling water pipe (male) (200B). In one embodiment, the block connecting member (101B) may correspond to a power cable (300) or include at least a part of the power cable (300). For example, if the block connecting member (101A) corresponds to a power cable (300) or includes at least a part of the power cable (300), the block connecting member (101B) may be a combination of a power cable (female) (300A) and a power cable (male) (300B). For example, if the block connecting member (101B) is a combination of a power cable (female) (300A) and a power cable (male) (300B), a plurality of containers (100) can be connected by the combination of the power cable (female) (300A) and the power cable (male) (300B). The external port (102) may be a base component formed in the shape of a metal perforation so that a cable or pipe can protrude or be drawn in from the outside of the housing. The direct connection interface may be directly connected in a horizontal or vertical direction between the battery block and the electrical block with the common lower support structure excluded. In another embodiment, the direct connection interface may form a hierarchical routing structure that is drawn vertically downward from the bottom of the blocks toward the common lower support structure and is directly connected to the busbar inside the skid. By applying a direct connection interface hardware structure based on such a joint surface, the physical length of wiring and piping, which previously required tens of meters per device in conventional systems, can be reduced to the shortest possible distance (e.g., a few centimeters). Consequently, this minimizes power transmission losses within the container and dramatically increases the volumetric density of equipment mounting within a confined space.The container of the present disclosure may include a fluid circulation hardware device for distributing a cooling medium generated to control heat generation to a plurality of modules in parallel. As illustrated in the upper and lower right of FIG. 5, the fluid circulation hardware device may include a cooling water pipe (200) and a cooling water pipe path connecting a chiller block (120) and a battery block (110). The cooling water pipe may be a tube structure formed of high-strength synthetic rubber or a metal alloy material to withstand high internal water pressure. As a coupling method, the cooling water pipe (200) may have a push-pull type male-female coupling structure in which a cooling water pipe (female) (200A) provided in one block and a cooling water pipe (male) (200B) provided in the other block are slidably inserted in a horizontal or vertical direction to be coupled. As a modified embodiment, if the lower support structure is omitted, the pipe routing may be routed directly only in the horizontal direction between the plurality of battery blocks. In addition, as a modified embodiment of the two-layer stacked structure, the left chiller pipe inside the chiller block may be directly connected vertically to the battery block of the upper layer, and the right chiller pipe may be connected horizontally to the battery block of the lower layer. By implementing such a direct routing structure for cooling water pipes that are independent for each layer or block, a technical effect can be achieved in which the phenomenon of water head reduction is physically prevented even in a multi-layer stacked environment, thereby enabling the stable supply of cooling water with a uniform flow rate to each battery rack without the installation of additional hydraulic pumps or motors. The container of the present disclosure may include an electrical routing device for transmitting large-capacity power output or input from the battery to a control device without loss. As illustrated in the upper and lower left of FIG. 5, the electrical routing device may include a power routing structure, a chiller power path, an externally exposed power cable, and a quick connector.The power cable may be a flexible cable made of a highly conductive copper (Cu) core wire and an insulating sheath capable of accommodating a high voltage (HV) high current of up to 350A. The quick connector may be a connection hardware in which the male and female terminals are connected by a snap motion of turning or pushing without the need for a separate hand tool. The quick connector may be integrally provided at both ends of the power cable (female) (300A) and the power cable (male) (300B) to physically and electrically connect them to each other. As a modified embodiment, in the case of an embodiment in which the upper support structure is excluded, battery power may be directly output to an external site network through the quick connector after passing through a DC power control device (DCPM), a power conversion device (PCS), and a fuse. On the other hand, in the case of an embodiment in which a common lower support structure is applied, power passing through the fuse may be introduced into the lower support structure (140) through the flexible power cable, sequentially pass through the first internal busbar and the skid connection part, and be output to the outside or extended in parallel to an adjacent container. By adopting a hardware structure for combining power cables and high-current quick connectors based on such flexible materials, mechanical assembly errors of several millimeters, which inevitably occur when stacking heavy modules weighing several tons using semi-automatic twist locks, can be flexibly absorbed. Furthermore, this protects against detachment of terminal connections or contact failures even in environments of fine vibrations from fans during power plant operation, thereby minimizing the probability of arc generation and reducing the time required for labor-intensive electrical wiring processes where workers must manually strip insulation and bolt at the site. The container of the present disclosure may include a hermetic and sealed hardware structure to prevent the interface area extending outside the housing of the block from being contaminated by external environmental factors (e.g., water, dust).The sealed hardware structure may be a cable gland structure that is fastened to a connecting member between blocks and a perforated hole of an external port, as illustrated in the center of FIG. 5. As a definition of the claimed terms and as a hardware component, the cable gland may be an assembly of bushings and joint components that prevent wire sheathing damage and physically compress and seal gaps when a power cable or cooling water pipe passes through a metal housing. The cable gland (400) may have a multi-sealed structure comprising a lock-nut assembly made of high-quality polyamide material, a silicone gasket, and a flexible conduit protection tube. In one embodiment, the modular energy storage system container (100) may include a cooling water pipe (female) (200A) on one side and a cooling water pipe (male) (200B) on the other side. For example, the cooling water pipe (female) (200A) may be provided horizontally within the modular energy storage system container (100). For example, the cooling water pipe (female) (200A) may be provided horizontally within the modular block and / or common lower support structure (140). For example, the cooling water pipe (male) (200B) may be provided vertically within the modular energy storage system container (100). For example, the cooling water pipe (male) (200B) may be provided vertically within the modular block. For example, when a battery block (110) includes a cooling water pipe (female) (200A) and a chiller block (120) includes a cooling water pipe (male) (200B), and the battery block (110) and the chiller block (120) are combined, the cooling water pipe (female) (200A) and the cooling water pipe (male) (200B) are joined together (e.g., by a snap-fit) so that a cooling medium provided inside the chiller block (120) can be introduced into the battery block (110).The cooling medium introduced into the battery block (110) can absorb heat generated in the battery rack and be returned to the chiller block (120). As another example, the cooling water pipe (female) (200A) may be provided vertically within the modular energy storage system container (100). For example, the cooling water pipe (female) (200A) may be provided vertically within the modular block and / or common lower support structure (140). For example, the cooling water pipe (male) (200B) may be provided horizontally within the modular energy storage system container (100). For example, the cooling water pipe (male) (200B) may be provided horizontally within the modular block. For example, when a battery block (110) includes a cooling water pipe (female) (200A) and a chiller block (120) includes a cooling water pipe (male) (200B), and the battery block (110) and the chiller block (120) are combined, the cooling water pipe (female) (200A) and the cooling water pipe (male) (200B) are joined together (e.g., by a snap-fit) so that a cooling medium provided inside the chiller block (120) can be introduced into the battery block (110). The cooling medium introduced into the battery block (110) can absorb heat generated from the battery rack and be returned to the chiller block (120). In one embodiment, the modular energy storage system container (100) may include a power cable (female) (300A) on one side and a power cable (male) (300B) on the other side. In one embodiment, the modular energy storage system container (100) may include a power cable (female) (300A) on one side and a power cable (male) (300B) on the other side. For example, the power cable (female) (300A) may be provided horizontally within the modular energy storage system container (100). For example, the power cable (female) (300A) may be provided horizontally within the modular block and / or common lower support structure (140).For example, a power cable (male) (300B) may be provided in a vertical or horizontal direction within a modular energy storage system container (100). For example, a power cable (male) (300B) may be provided in a vertical or horizontal direction within a modular block. For example, when a battery block (110) includes a power cable (female) (300A) and an electrical block (130) includes a power cable (male) (300B), and the battery block (110) and the chiller block (120) are combined, the power cable (female) (300A) and the power cable (male) (300B) may be joined together (e.g., by a snap-fit) to allow power generated inside the electrical block (130) to flow into the battery block (110). Power supplied into the battery block (110) can be transferred to the battery rack and used to charge the battery. As another example, a power cable (female) (300A) may be provided in a vertical or horizontal direction within the modular energy storage system container (100). For example, the power cable (female) (300A) may be provided in a vertical or horizontal direction within the modular block and / or common lower support structure (140). For example, a power cable (male) (300B) may be provided in a horizontal direction within the modular energy storage system container (100). For example, the power cable (male) (300B) may be provided in a horizontal direction within the modular block. For example, when a battery block (110) includes a power cable (female) (300A) and an electrical block (130) includes a power cable (male) (300B), and the battery block (110) and the chiller block (120) are combined, the power cable (female) (300A) and the power cable (male) (300B) are joined together (e.g., by a snap-fit) so that power generated inside the electrical block (130) can be introduced into the battery block (110). The power introduced into the battery block (110) can be transferred to a battery rack and used to charge the battery.In the present disclosure, the orientation in which the cooling water pipe (200) and power cable (300) are arranged is not limited to the examples listed and may be modified according to the user's needs. In one embodiment, the cooling water pipe (female) (200A) may include a lock nut (female) (210A) and a waterproof ring (230A). In one embodiment, the lock nut (female) (210A) securely fastens the pipe port to the outer wall housing of the battery block (110) to prevent the pipe from detaching due to external impact or water pressure generated during cooling water circulation. In one embodiment, the waterproof ring (230A) is formed of a high-elasticity silicone or synthetic rubber material, so that high-grade waterproof performance can be ensured by physically compressing the fine gap between the interfaces when the male and female pipes are joined. For example, the waterproof ring (230A) inside the cooling water pipe (female) (200A) installed at the bottom outer port of the battery block (110) can be tightly fitted to the inner wall of the pipe when the male terminal extending from the chiller block (120) is inserted, so that the high-pressure cooling medium does not leak out. In one embodiment, the cooling water pipe (male) (200B) may include a lock nut (male) (210B) and a gasket (220B). In one embodiment, the gasket (220B) is located at the tip of the male terminal so that it can be directly compressed to form a seal when joined in a push-pull manner with the cooling water pipe (female) (200A). In one embodiment, the lock nut (210B) can provide structural stability to the joint by suppressing rotation or horizontal flow of the pipe after joining. For example, when transferring cooling water generated from the left chiller (121) of the chiller block (120) to the two-layer battery block, the cooling water pipe (200B) routed vertically can maintain a stable fluid connection state while absorbing assembly errors of several millimeters that occur during stacking between blocks by utilizing the compressive force of the gasket (220B).In one embodiment, the power cable (female) (300A) may include a lock nut (female) (310A) and a lock nut (male) (310B). In one embodiment, the power cable (female) (300A) takes the form of a flexible cable (401) structure for transmitting high voltage (HV) high current, and the cable is secured without shaking within a block housing or cable gland (400) through a double lock nut (310A, 310B) fastening structure. This can minimize the risk of electrical connection failure or arc generation by dispersing the physical tensile load applied to the connection terminal by the self-weight of the cable. For example, when routing power from the DC power control device (141) inside the battery block (110) to the power converter (142) of the electrical block (130), the lock nuts (310A, 310B) provided at the bottom of each block physically restrain the high-capacity cable, thereby ensuring a stable electrical conduction state even in a vibrating environment during container movement. FIG. 6 is a diagram illustrating the configurations within the blocks constituting a modular energy storage system container according to one embodiment of the present disclosure. Referring to FIG. 6, a modular energy storage system container (100) that does not include a common lower support structure (140) is disclosed. In FIG. 6, the internal hardware device arrangement and routing structure of a modular energy storage system container (100) is schematically illustrated. In one embodiment, the battery block (110) is configured such that the explosion-proof panel is deployed upward to avoid pressure discharge interference of the upper layer when vertically stacked, and includes a quick connector-based interface on the side or bottom for connecting DC cables and cooling water plumbing between adjacent blocks. In one embodiment, the battery block (110) may include a DC power control device (DCPM) for managing DC power.For example, a battery rack within a battery block (110) can be managed by a DC power control device, and the DC power control device can supply DC power to the battery rack using power obtained from an electrical block (130). For example, the battery block (110) is fixedly mounted integrally with the battery rack to control power, and the energy density of the system is approximately 450 kWh / m² per unit area. 2Technical effects that improve up to [amount] can be provided. In one embodiment, there may be at least two chiller blocks (120), and they may be arranged as a left chiller and a right chiller depending on the installation location and assigned area. For example, each chiller block (120) can deliver a cooling medium to different battery blocks among a plurality of battery blocks. For example, if the battery blocks are arranged in two rows, the left chiller can deliver a cooling medium to the battery blocks arranged in the left row, and the right chiller can deliver a cooling medium to the battery blocks arranged in the right row. Depending on the implementation mode, a chiller block (120) using a single chiller is also possible. In one embodiment, the electrical block (130) may be a module that integrates power conversion and control of the entire system. For example, the electrical block (130) may include a power conversion device (PCS) (142), a (auxiliary) transformer (134), and an uninterruptible power supply (UPS) (131). Additionally, the electrical block (130) may include a system battery management system (SBMS) for monitoring the battery status of the entire system and a fire alarm controller (FACP) (132) for fire detection and control. As the skid is excluded, the electrical block (130) may accommodate an AC power supply (131), a fire alarm controller (132), a heat exchanger (133), and a transformer (134) inside, in addition to a power converter (142), and function as an integrated infrastructure base. The container (100) of the present disclosure may be composed of an integrated infrastructure hardware system that performs storage, control, conversion, and thermal management of large-capacity power. As illustrated in FIG. 6, the integrated infrastructure hardware system may include a plurality of battery blocks (110), chiller blocks (120), and electrical blocks (130) having independent housings according to function. The modular energy storage system container (100) may be an energy storage structure for a large-scale power plant in which a plurality of standardized modules are assembled and connected to a power grid.The battery block (110) may be a space for physically storing power, the chiller block (120) may be a space dedicated to thermal management for cooling the heat generated by the battery, and the electrical block (130) may be a space dedicated to power management for converting power and controlling a safety system. The container (100) may have a direct connection structure in which the battery block (110), chiller block (120), and electrical block (130) are directly connected to each other in a vertical or horizontal direction solely by their own weight, with the common lower support structure (140) completely excluded. The container (100) of the present disclosure may include power storage and control hardware that physically stores DC power and directly controls the input and output of said power at a lower level. The power storage and control hardware may be at least one battery block (110) that includes a plurality of battery racks and a DC power control device (141) inside. The battery rack may be a physical frame in which a plurality of battery cells that charge and discharge energy are stacked in layers. The DC power control device (141) may be a hardware control panel that monitors the voltage and current status of the battery and forcibly switches and cuts off the DC power when an abnormality occurs. In a container (100) in which a common lower support structure (140) is excluded, the DC power control device (141) may be fixedly positioned in the lowest central area inside each battery block (110) in place of the lower skid and may be electrically connected directly to the battery rack. Additionally, in an embodiment where a skid is present, the power inside the battery blocks (110) stacked in multiple layers may be collected first by the DC power control device (141) located at the bottom of the first layer and then controlled.By adopting a hardware structure in which the DC power control device (141) is directly embedded in the lower block, the battery control and cutoff functions can be performed independently and completely without mounting control components on a heavy steel skid frame. Additionally, by minimizing the length of the physical DC cable wiring between the battery and the controller, the power transmission loss (voltage drop) that inevitably occurs during operation can be suppressed, and the structural performance enhancement effect can be provided to dramatically improve hardware control reliability. The power converter (142) may be a high-capacity high-voltage inverter that converts the DC power of the battery into AC power for transmission to the power grid. The uninterruptible power supply (131) may be an uninterruptible power supply (UPS) that continuously supplies auxiliary control power to the control system even in the event of an external power grid outage. The transformer (134) may be electromagnetic induction hardware that independently steps down or steps up the voltage to drive electrical components. The fire alarm controller (132) may be a fire control panel that processes disaster signals in conjunction with smoke detectors, etc., within the battery module. The heat exchanger (133) may be heat dissipation hardware that releases heat generated from electrical components to the outside through cooling water or air. The electrical block (130) may collectively accommodate electrical components (131, 132, 133, 134, 142) in its internal space to replace the equipment mounting function performed by the common lower support structure (skid). As a modified embodiment of the external site network entry, an external site cable for transmitting and receiving power may be directly entered into the container through a hole perforated in the rear panel or lower panel of the electrical block (130) and directly connected to a transformer (134) or power converter (142).In this way, by concentrating and mounting the high-capacity power converter (142) and control electrical components, which pose a high-voltage risk, inside a separate, independent electrical block (130) housing, a physical firewall effect can be provided to prevent the flame from spreading to expensive electrical components in the event of a battery thermal runaway fire. The container (100) of the present disclosure can achieve simultaneous improvement in mechanical and electrical performance by completing the complex and difficult wiring connection work, which was previously involved when scattered sporadically within a conventional skid, in advance at the factory assembly stage within a single module, thereby drastically reducing labor costs and installation time for electrical work at the site. The container (100) of the present disclosure may include a left chiller and a right chiller provided inside a chiller block (120) to generate and distribute a cooling medium in parallel to a plurality of modules that generate heat during system operation. The chillers may be liquid cooling temperature control devices that generate a coolant through a compressor and a condenser and circulate it through pipes. When the battery block (110) is stacked in a vertical two-layer structure as shown in FIG. 6, the left chiller can be independently connected to the cooling water pipe of the upper two-layer battery block without the additional installation of a separate external hydraulic pump or motor, and the right chiller (122) can be horizontally independently connected to the cooling water pipe of the lower one-layer battery block. The cooling water generated in the chiller block (120) can also be routed in parallel to the heat exchanger (133) inside the adjacent electrical block (130) to simultaneously control the temperature of the power components. By implementing this dual chiller structure and a layer-by-layer individual direct pipe routing method, the phenomenon of water head drop inside the pipes, which was a chronic problem under a multi-layer stacked module structure, can be overcome.Accordingly, the power consumed for pump operation can be drastically reduced, and at the same time, a uniform flow of cooling water is stably supplied to the entire upper and lower battery modules, thereby achieving a thermodynamic performance maximization effect that suppresses the risk of thermal runaway disasters. The container (100) of the present disclosure may include a hierarchical electrical routing sequence structure for collecting power produced from individual modules and safely transmitting it to an external transmission network. The routing sequence may be a power path in which power released from the battery block (110) sequentially passes through the DC power control device (141) and the power converter (142) of the electrical block (130). The battery power can be collected by the busbar inside the electrical block (130) after sequentially passing through the DC power control device (141), the power converter (142), and the fuse, and then directly transmitted to a cable at an external site. In an alternative embodiment, where a skid is present, power passing through the fuse is fed downward along the main power cable and interfaces with a first internal busbar pre-embedded within the common lower support structure, and subsequently passes sequentially through the skid connection and the second internal busbar of another skid of an adjacent container to form a sequence in which it is finally output in parallel to an external network. FIG. 7 is an illustration for exemplarily explaining the connection structure of blocks constituting a modular energy storage system container according to one embodiment of the present disclosure. FIG. 7 schematically illustrates the internal routing path between heterogeneous blocks of the modular energy storage system container (100). The power routing structure (500) and the cooling water piping path (510) can provide a physical trajectory through which current and a high-pressure cooling medium actually flow between the heterogeneous blocks. Referring to FIG. 7, a modular energy storage system container (100) that does not include a common lower support structure (140) is disclosed.Through the structure of FIG. 7, a DC cable-based power routing structure (500), a cooling pipe-based cooling water piping path (510), and a chiller power path (520) can be implemented to interconnect an electric field block (130), a plurality of battery blocks (110), and a chiller block (120) without an intermediate medium. In one embodiment, the modular energy storage system container (100) does not include a common lower support structure (140), so power generated from the electric field block (130) can be directly transferred to other blocks (e.g., battery blocks (110)) through the power routing structure (500). For example, the power routing structure (500) may include a power cable (300). For example, the power routing structure (500) may be connected vertically and / or horizontally from the electric field block (130) to the battery block (110). For example, a power routing structure (500) connected to a battery block (110) can be connected to a DC power control device within the battery block (110) to transfer power to a battery rack through the DC power control device. In one embodiment, the modular energy storage system container (100) does not include a common lower support structure (140), so power generated in the electrical block (130) can be transferred directly to the chiller block (120) through the chiller power path (520). The power transferred through the chiller power path (520) can be used to cool a cooling medium within the chiller block (120). For example, the chiller power path (520) may include a power cable (300). In one embodiment, the modular energy storage system container (100) does not include a common lower support structure (140), so the cooling medium provided in the chiller block (120) can be transferred to other blocks (e.g., battery block (110)) through the cooling water piping path (510). The cooling medium transferred through the cooling water piping path (510) can be used to cool the heat generated within the battery block (110).For example, the cooling water piping path (510) may include a cooling water pipe (200). For example, the cooling water piping path (510) may be connected from the chiller block (120) to the battery block (110) and may be provided between the battery racks included within the battery block (110). For example, it may be connected horizontally from the chiller block (120) to the battery block (110) and may be provided vertically between the battery racks included within the battery block (110). In one embodiment, the chiller block (120) may be designed to independently route the generated cooling water to each layer of the battery block (110) through the cooling water pipe and to provide uniform cooling performance throughout the vertically stacked battery block (110) without the need for a separate additional pump. For example, power and control signals for driving the chiller block (120) are configured to be received in horizontal and vertical directions through a chiller power control unit extending from the electrical block (130) since the common lower support structure (140) is not included. In one embodiment, the chiller block (120) can independently deliver the generated coolant to each layer's battery block (110) through a coolant piping path (510). For example, the left chiller (121) can directly supply coolant to the upper layer block, and the right chiller (122) can directly supply coolant to the lower layer block, thereby ensuring uniform cooling performance without an additional hydraulic pump. The container (100) of the present disclosure can implement fluid circulation routing for controlling temperature by individually distributing a cooling medium in parallel to the heat-generating battery rack area. As illustrated in FIG. 7, fluid circulation routing can be implemented through a cooling water piping path (510) that branches out and extends from the chiller block (120) to the battery block (110) and the electrical block (130), respectively. The cooling water piping path (510) may be in the form of a three-dimensional arrangement of cooling pipes made of high-strength synthetic rubber or metal alloy to withstand high internal liquid pressure and micro-vibrations of the system.Fluid circulation routing can be applied as an independent piping branch structure to each of the battery blocks (110) stacked in two layers as shown in FIG. 7. Without the installation of a separate hydraulic boosting pump or motor, the cooling water piping generated from the left chiller within the chiller block can be directly routed by extending horizontally and rising vertically to the battery blocks located in the upper second layer. In parallel, the cooling water piping generated from the right chiller can be directly routed by extending horizontally to the battery blocks located in the lower first layer. As a modified embodiment, the cooling water piping path (510) output from the chiller block can also be routed horizontally in parallel toward the heat exchanger inside the adjacent electrical block to simultaneously control the heat generation of the electrical components. By applying a hardware structure of independent cooling water piping paths (510) separated by layer (e.g., 1:1 matching), the phenomenon of hydrostatic pressure drop that inevitably occurs when pulling up piping from the bottom to the top in a multi-layer block stacking environment of two or more layers can be blocked. As a result, the system operating power consumed to additionally drive the large-capacity hydraulic pump is drastically reduced, and at the same time, the risk of disaster due to battery thermal runaway can be prevented by stably distributing cooling water of a uniform flow rate without error across the entire upper and lower battery rack areas. In one embodiment, the electrical block (130) may be a module that performs integrated power conversion and control of the entire system. For example, since the electrical block (130) does not include a common lower support structure (140), it may include an AC power device including a power conversion device (142), an auxiliary transformer, a heat exchanger which is a thermal management device that releases heat inside the block to the outside or transfers heat generated in a specific block to a cooling medium to maintain the operating temperature of the components within an optimal range, and an uninterruptible power supply (UPS). For example, the electrical block (130) may also include a system battery management system (SBMS) that monitors the battery status of the entire system and a fire alarm controller for fire detection and control.For example, power output from the electrical block (130) can be directly transmitted to the DC power control device (141) of the battery block (110) through the power routing structure (500) to control the charging and discharging of the battery rack. In one embodiment, the electrical block (130) may be equipped with a dehumidifier to regulate internal humidity for the protection of sensitive electrical devices, and an air intake and exhaust fan to release internal heat to the outside. In one embodiment, routing of piping and power cables may be performed only in the horizontal direction between the battery blocks (110), and may be simultaneously connected in the horizontal and vertical directions from the chiller block (120) and the electrical block (130) to form a shortest path interface. The container (100) of the present disclosure may implement high voltage (hv) electrical routing to transfer large amounts of DC power, which is chemically released or charged from the battery module, to the power control device without loss. High-voltage electrical routing can be implemented by a power routing structure (500) and / or a DC cable that traverses the bottoms of multiple battery blocks and energizes the electrical blocks in a mutually transverse direction. The DC cable may be, for example, a flexible cable made of a highly conductive copper core wire and a flexible insulating sheath capable of safely accommodating a high-voltage high current of up to 350A. With the common lower support structure (140) excluded, the power routing structure (500) may have an energization sequence in which power output from the battery rack is collected by a DC power control device (141) at the bottom of each battery block, then sequentially penetrates horizontally arranged neighboring battery blocks in a transverse direction, and finally enters the power converter side of the electrical block (130). As a modified embodiment, whenever the cable passes through the walls of heterogeneous blocks, a cable gland including a quick connector and a lock nut as a block connecting member may be fastened to the external port area to form a hermetic binding structure that absorbs vibration.The container (100) of the present disclosure may implement auxiliary power distribution for distributing auxiliary driving power and fire control signals for thermal management infrastructure from a centralized block to individual devices. Auxiliary power distribution may be implemented by a chiller power path that supplies auxiliary power and low-voltage power from an electrical block toward an adjacently assembled chiller block (120). The chiller power may be an AC or DC driving voltage supplied to physically rotate and drive the motors of the compressor, condenser, and ventilation exhaust fan mounted inside the chiller block. The chiller power path (520) may be structured such that it is generated from an AC power supply or a step-down transformer housed inside the electrical block and is fed into the chiller block by the shortest horizontal distance through a cable gland and a push-pull type quick connector provided on the side joint wall. As a modified embodiment, the chiller power path (520) may be configured such that not only power lines but also fire communication control cables linked to a fire alarm controller within the electrical block are bundled and routed in parallel, thereby immediately and forcibly shutting off the operation and power of the chiller upon detection of smoke within the battery block. By applying a hardware routing architecture that collectively houses high-voltage electrical components and auxiliary control power devices within an independent electrical block housing and directly connects the chiller power path (520) to an adjacent chiller block, the direct transfer of flames to expensive core electrical components can be prevented in the event of a disaster fire, such as abnormal thermal runaway of the battery. FIG. 8 is an illustration for exemplarily explaining the internal structure and connection relationships of blocks constituting a modular energy storage system container according to an embodiment of the present disclosure. Referring to FIG. 8, a modular energy storage system container (100) including a common lower support structure (140) is disclosed.A schematic diagram illustrating the block-by-block accommodation relationship and control linkage structure of internal hardware components of a modular energy storage system container according to one embodiment of the present disclosure is illustrated in FIG. 8. In one embodiment, when the modular energy storage system container (100) includes a common lower support structure (140), the battery block (110) may include only a battery rack and not a DC power control device within the battery block (110). For example, a DC power control device (141) that controls the power of the battery block (110) may be included in the common lower support structure (140). For example, the battery block (110) may include an exhaust fan and an air intake in addition to the battery rack. In one embodiment, the chiller block (120) may be designed to independently route the generated cooling water to each layer of the battery block (110) through a cooling water pipe and to provide uniform cooling performance throughout the vertically stacked battery blocks (110) without a separate additional pump. For example, power and control signals for driving the chiller block (120) are configured to be transmitted in horizontal and vertical directions through a chiller power control unit extending from the common lower support structure (140) and / or the electrical block (130). In one embodiment, instead of the electrical block (130), the common lower support structure (140) may be a module that performs integrated power conversion and control of the entire system. For example, the common lower support structure (140) may include a power conversion device (142), an auxiliary transformer (134), a heat exchanger (133) which is a thermal management device that releases heat inside the block to the outside or transfers heat generated in a specific block to a cooling medium to maintain the operating temperature of the components within an optimal range, and an AC power device (131) including an uninterruptible power supply (UPS).For example, the common lower support structure (140) may also include a system battery management system (SBMS) for monitoring the battery status of the entire system and a fire alarm controller (132) for fire detection and control. In one embodiment, the common lower support structure (140) may be equipped with a dehumidifier for controlling internal humidity to protect sensitive electrical devices and an air intake and exhaust fan for releasing internal heat to the outside. In one embodiment, the components included in the battery block (110), chiller block (120), and electrical block (130) may differ depending on whether the common lower support structure (140) is included. For example, when the common lower support structure (140) is included, the battery block (110) may not include a DC power control device (141), and the DC power control device (141) may be included in the common lower support structure (140). For example, if a common lower support structure (140) is not included, a DC power control device (141) may be included in the battery block (110) and / or electrical block (130) instead of the common lower support structure (140). In one embodiment, the container (100) may group and manage a plurality of battery blocks (110) in units of PODs (e.g., PODs 1 to 4). For example, each POD is connected to a system battery management system (SBMS) within an electrical block (130) via an independent communication channel, and when a fire is detected or a voltage abnormality occurs in a specific POD, the circuit of that POD can be selectively shut off through a DCPM (141) and a fire alarm controller (132) to maintain the availability of the entire system. As illustrated in FIG. 8, the container (100) may be a modular energy storage system container (100) comprising a plurality of spatially and functionally divided battery blocks (110), chiller blocks (120), electrical blocks (130), and a common lower support structure (140).A modular energy storage system container (100) may be a power generation facility in which multiple standardized modules are assembled on-site. As a modified embodiment, the container (100) may include a common lower support structure (140) located at the lowest base to integrally support the upper blocks (110, 120, 130). Depending on the implementation mode, as another embodiment, the common lower support structure (140) may be excluded, and a direct routing structure may be applied in which the frame is formed only by physical direct connection (e.g., semi-automatic twist lock and C-shaped bracket) between the battery block (110), chiller block (120), and electrical block (130). By implementing a container architecture of functional modules that encompasses both the presence and absence of a lower skid, the horizontal and vertical expansion of the facility can be easily designed to suit the customer's site environment and required capacity. In particular, when the skid is excluded, the utilization of idle space inside the module can be maximized, thereby increasing the energy density of the container to a maximum value per unit area (e.g., 450 kWh / m²) and achieving a performance improvement effect that reduces overall transportation costs. The container (100) of the present disclosure may include a power storage and switching configuration that physically loads DC power from battery cells and directly controls the input and output of said power at the bottom. As illustrated in FIG. 8, the power storage and switching configuration may be a battery block (110) including a plurality of battery rack areas and a DC power control device (141) electrically connected thereto. A battery rack area may be a hardware frame in which a plurality of cells and modules are stacked in series and parallel. The DC power control device (141) may be a high-voltage control panel that monitors the voltage and current status of the battery and cuts off a physical switch when an overcurrent occurs. The present disclosure may include a central control configuration that performs DC-AC conversion of power and comprehensively manages the auxiliary power of the entire system and fire disasters.The central control configuration may consist of a power converter (142), an AC power supply (131) housed within an electrical block (130), a fire alarm controller (132), a heat exchanger (133), and a (auxiliary) transformer (134). In an embodiment where a skid is present, as shown at the bottom of FIG. 8, the power converter (142) and the dehumidifier are housed within a common lower support structure (140), and the remaining control devices (131, 132, 133, 134) may be housed separately within an upper electrical block (130). On the other hand, in an embodiment without a common lower support structure (140), for example, the electrical block (130) may replace the skid to house all electrical control components, including the power converter (142), collectively within a single housing. The container (100) of the present disclosure may have a left chiller (121) and a right chiller (122) inside a chiller block (120), and a chiller piping structure. The chiller may be an independent water-cooled temperature control device that drives a compressor and a condenser to generate liquid cooling water. When a skid is applied, the cooling water may be concentrated inside the lower support structure (140) and then surge upward and be distributed to each block. On the other hand, in an embodiment where the battery block (110) is stacked in two layers without a skid, the cooling piping of the left chiller (121) may be vertically extended upward to the upper (second layer) battery blocks and then directly connected horizontally without the installation of an additional hydraulic boosting pump, and the cooling piping of the right chiller (122) may be horizontally extended to the lower (first layer) battery blocks to form a direct routing structure. As a modified embodiment, some of the chiller piping may also be directly connected in parallel to a heat exchanger (133) inside an electrical block (130). By adopting the configuration of independent left / right chillers (121, 122) and the floor-by-floor split direct connection piping routing method, the phenomenon of water head reduction that inevitably occurs when pulling up piping from the bottom to the top when stacking modules to a height of two floors or more can be overcome.The container (100) of the present disclosure may include a venting structure. The venting structure may include an external air inlet louver attached to the battery block (110), an exhaust fan for exhausting internal heat, and an explosion-proof panel device (106, 107). The explosion-proof panel device used in the present disclosure may collectively refer to any disaster safety assembly for physically detecting abnormal explosion pressure inside the container and safely releasing flames to the outside. The explosion-proof panel device may include the explosion-proof panel described above as a substantial opening and closing means or correspond thereto. FIG. 9 is a drawing for illustrating a member connecting power and cooling water piping included within a modular energy storage system container according to one embodiment of the present disclosure. Referring to FIG. 9, an enlarged exploded view and an assembly view are presented showing a sealed coupling structure based on a quick connector and a cable gland (400) penetrating a block of a modular energy storage system container (100) according to one embodiment of the present disclosure. Referring to FIG. 9, the modular energy storage system container (100) may include a cable gland (400) and a cable (401) to facilitate the installation of a cooling water pipe (200) and a power cable (300). In one embodiment, the cable gland (400) may be a mechanism installed at the entry point of a cable (401) penetrating a block or the outer wall of a common lower support structure (140) to firmly secure the cable and maintain a seal at the penetration site. For example, the cable gland (400) may be formed to include a gasket, a lock nut, and a dedicated connector. In one embodiment, the cable gland (400) may be applied to a main power cable entry point for connection with an external site power grid, or may be used by being coupled to a through hole in a skid connection between containers. In one embodiment, the cable gland (400) may be used to ensure electrical and fluid connection reliability between blocks.For example, a cable gland (400) (e.g., a conduit structure) can be applied to the inlet of a power cable (300) connecting the DC power control device (141) of the battery block (110) and the power conversion device (PCS) of the electrical block (130). Through this, the cable gland (400) can block the intrusion of moisture or dust from the outdoor environment, thereby securing a waterproof and dustproof rating of IP65 or higher, and enabling stable power supply and signal transmission. In one embodiment, the path of the cooling water piping (200) between the chiller block (120) and the battery block (110) can be arranged in parallel with the power cable (300). At this time, the cable gland (400) or busbar bushing may be coupled to a side hole of the block connecting member (101) or common lower support structure (140) through which the cable and piping pass, thereby maintaining the airtightness of the entire system. In one embodiment, to absorb vibrations occurring during the movement of the modular container or fine tolerances during field assembly, the cable gland (400) may be coupled with a flexible cable (401) to form a flexible fastening structure. This may provide a technical effect of reducing errors occurring during assembly and relieving physical stress on the connection part. In one embodiment, the cable gland (400) is applied to the penetration part of the skid connection that interconnects the first common lower support structure and the second common lower support structure, thereby enabling the waterproof performance inside the container to be continuously maintained even during lateral parallel expansion. In one embodiment, the cable (401) refers to a flexible line for transmitting power or control signals and may include a power cable (300) or a flexible cable having a structure in which a central circular conductor (stranded wire) is wrapped with an insulator and a sheath. For example, the cable (401) is suitable for wiring complex paths and can perform the role of absorbing vibration and assembly errors.In one embodiment, the cable gland (400) may be characterized by being applied as follows to ensure the reliability of the electrical and fluid connection between blocks using the cooling water pipe (200) and the power cable (300). For example, the cable gland (400) may be applied to the inlet of the power cable (300) connecting the DC power control device (141) of the battery block (110) and the power conversion device (PCS) of the electrical block (130). Through this, the cable gland (400) can block the intrusion of moisture or dust from the outdoor environment to ensure a waterproof and dustproof rating of IP65 or higher, and enable stable power supply and signal transmission. In one embodiment, the cooling water pipe (200) path between the chiller block (120) and the battery block (110) may be arranged in parallel with the power cable (300). At this time, the cable gland (400) or busbar bushing may be coupled to a side hole of the block connecting member (101) or common lower support structure (140) through which the cable and pipe pass, thereby maintaining the airtightness of the entire system. In one embodiment, to absorb vibrations occurring during the movement of the container or fine tolerances during field assembly, the cable gland (400) may be coupled with a flexible cable (401) to form a flexible fastening structure. This may provide a technical effect of reducing errors occurring during assembly and relieving physical stress on the connection part. In one embodiment, the cable gland (400) is applied to a penetration part of the skid connection that interconnects the first common lower support structure and the second common lower support structure, thereby continuously maintaining the waterproof performance inside the container even during lateral parallel expansion. As shown in the assembly diagram on the right side of FIG. 9, the container (100) may include a cooling water pipe (200) and a power cable (300) that extend to an adjacent block by penetrating a hole in the outer wall of the metal housing.The cooling water piping may be a high-strength pressure-resistant tube for transferring liquid cooling water generated in the chiller block to the battery rack, and the power cable may be a wire based on a highly conductive copper (cu) core wire capable of accommodating, for example, a high voltage (hv) of up to 350A. In an embodiment where a common lower support structure (skid) is excluded, the power cable (300) and the cooling water piping (200) may be directly engaged in horizontal and vertical directions through the joint surface between the battery block and the electrical block stacked vertically or horizontally to form a direct direct routing structure. In an embodiment where a lower skid is present, the power cable (300) may be bent vertically downward and connected to a first internal busbar inside the common lower support structure, or arranged to connect neighboring skids in parallel in the horizontal direction via a flexible busbar of the skid connection part. The container (100) of the present disclosure may include a gap sealing and airtight structure to prevent the cable and piping areas passing through the thick metal housing from being contaminated by external harsh environmental factors (e.g., moisture, dust, salt). As shown in the left exploded view of FIG. 9, the airtight structure may be a cable gland (400) assembly that wraps around the outer surface of the cable (401) and is fastened by being forcibly compressed into a hole in the outer wall of the block. The cable gland (400) may be an assembly of multiple bushing components that prevent mechanical tearing damage to the wire sheath and hydrodynamically seal the gap. For example, the cable gland (400) may include a threaded lock-nut assembly, a gasket that physically expands by the tightening torque of the lock-nut to fill the gap, and a waterproof ring.A sealing mechanism may be applied in which a silicone or rubber gasket (220B) and a waterproof ring (230A) are inserted into the connection portion of a cooling water pipe (female) (200A) and a cooling water pipe (male) (200B) having a male-female coupling structure, and a lock nut (female) (210A) and a lock nut (male) (210B) made of polyamide (pa6) are rotatably fastened and compressed around the outer portion. In another embodiment, the connection portion of a power cable (female) (300A) and a power cable (male) (300B) may also be compressed and fixed by a lock nut (female) (310A) and a lock nut (male) (310B) in the same manner, and the externally exposed area may be additionally protected by a corrugated synthetic resin conduit tube cover.
