Description

Technical Field

[0001] The present disclosure relates to a container module.

[0002] This application claims priority from Korean Patent Application No. 10-2023-0119309, filed on September 7, 2023, and Korean Patent Application No. 10-2023-0182298, filed on December 14, 2023, the disclosures of which are incorporated herein by reference. Background Art

[0003] At present, commercially available secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, lithium secondary batteries, etc., and among them, lithium secondary batteries have little or no memory effect, so they have received more attention than nickel-based secondary batteries because they have the advantages of being able to be recharged at any convenient time, having a very low self-discharge rate, and having a high energy density.

[0004] With the recent rise of issues such as power shortages and the need for eco-friendly energy, energy storage systems (ESS) for storing electricity for later use have been gaining increasing attention. For example, one proposed method for controlling power supply is the smart grid system. Electricity usage is not constant and can change at any time. Typically, during the summer, daytime electricity usage increases dramatically due to the use of cooling equipment, while it decreases sharply at night. From the perspective of power consumption, power consumption is not constant and can change frequently. From the perspective of power supply, the amount of power generated can be controlled to a certain extent, but in reality, it is difficult to meet the required power. Therefore, due to the imbalance between power supply and power consumption, oversupply or undersupply can occur. To address this problem, smart grid systems can flexibly store and control power. The concept of a smart grid system is to store electricity during times or areas with power surpluses and to supply this stored power during times and areas with power shortages. One of the basic elements used to build a smart grid system can be an energy storage system for storing electricity. With the recent widespread use of electric vehicles, energy storage systems are being used in facilities that charge electric vehicles, such as charging stations.

[0005] Energy storage systems can include multiple battery containers. The number and placement of battery containers can vary depending on different environments and requirements. To meet these demands, there is a growing demand for battery containers that combine small modules to increase energy density and can be configured in many different shapes and forms.
