Description

TECHNICAL FIELD The present disclosure relates to a container module. The present application claims priority to Korean Patent Application No. 10-2023-0119310 filed on September 7, 2023, Korean Patent Application No. 10-2023-0182382 filed on December 14, 2023 and Korean Patent Application No. 10-2024-0035929 filed on March 14, 2024 in the Republic of Korea, the disclosures of which are incorporated herein by reference. BACKGROUND Currently, commercially available secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, lithium secondary batteries and the like, and among them, lithium secondary batteries have little or no memory effect, and thus they are gaining more attention than nickel-based secondary batteries for their advantages that recharging can be done whenever it is convenient, the self-discharge rate is very low and the energy density is high. Recently, with the emerging issues such as a lack of power or eco-friendly energy, Energy Storage Systems (ESS) used to store power for later use are gaining more attention. For example, one of proposed methods for controlling power supply is smart grid systems. The power usage is not constant and can change at any time. Typically, the power usage sharply increases in the summer daytime due to the use of cooling devices and sharply decreases in the nighttime. From the perspective of power consumption, power consumption is not constant and may frequently change, but from the perspective of power supply, the amount of power produced can be controlled to some extent, but in reality, it is difficult to meet the amount of power required. Accordingly, power oversupply or power shortage may occur due to the inequality in power supply and power consumption, and to solve this problem, the smart grid systems may flexibly store and control power. The concept of smart grid systems is that power is stored in times or regions in which surplus power occurs and the stored power is supplied in times and regions in which power shortage occurs. One of the essential elements for building the smart grid systems may be energy storage systems for storing power. More recently, with the widespread use of electric vehicles, energy storage systems may be used in facilities for charging the electric vehicles, for example, charging stations. The energy storage system may include a plurality of battery containers. The number of battery containers and their placement may vary depending on different environments and requirements. To meet the requirements, there is a growing need for a battery container made up of a combination of small modules to improve energy density. Additionally, there is a growing need for a battery container that is easy to install and assembly to improve assembly efficiency and change to many different shapes and forms. SUMMARY Technical Problem An object of the present disclosure is to solve these and other problems. Another object of the present disclosure is to provide a container module with improved assembly efficiency. Still another object of the present disclosure is to provide a container module of simple structure. Yet another object of the present disclosure is to provide a container module of smaller size. Further still another object of the present disclosure is to provide a container module that is easy to install a battery pack. Technical Solution To achieve the above-described objects, a container module according to an embodiment of the present disclosure includes a case configured to provide an internal space; a column located inside the case and extended in a top-bottom direction; a bracket including a vertical portion coupled to the column and a horizontal portion extended from the vertical portion; a battery pack located on the horizontal portion; and a support located below the bracket, and configured to support a lower surface of the horizontal portion. Additionally, the horizontal portion may include a first part extended from the vertical portion; and a second part extended from the first part, and coming into contact with the battery pack, and the support may support the second part. Additionally, the support may include a horizontal support portion configured to support the lower surface of the horizontal portion; and a vertical support portion coupled to the column. Additionally, the support may further include a truss part obliquely connecting the horizontal support portion to the vertical support portion. Additionally, the support may further include a connection portion connecting the horizontal support portion to the vertical support portion in a curved way. Additionally, the vertical support portion may be extended in the top-bottom direction, the horizontal support portion may be extended toward the column, and the vertical support portion and the horizontal support portion may be connected to form a corner. Additionally, the horizontal support portion and the horizontal portion may be
