Description

Container module

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

[0002] This application claims priority to Korean Patent Application No. 10-2023-0190454, filed December 22, 2023, and Korean Patent Application No. 10-2024-0189543, filed December 18, 2024, the entire contents of which are incorporated herein by reference.

[0003] Currently commercialized secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, and lithium secondary batteries. Among these, lithium secondary batteries are receiving attention for their advantages of being able to charge and discharge freely, having a very low self-discharge rate, and having a high energy density, as they have almost no memory effect compared to nickel-based secondary batteries.

[0004] Recently, with the rise of issues such as power shortages and eco-friendly energy, energy storage systems (ESS) for storing generated power are attracting increasing attention. For example, smart grid systems have been proposed as a solution to regulate power supply and demand. The amount of power consumed by consumers is not always constant and can fluctuate frequently. A prime example is the sharp increase in power usage during summer afternoons due to the use of air conditioning, followed by a sharp decrease at night. While power consumption can fluctuate and fluctuate frequently, it is realistically difficult to match this demand, even with some degree of power production adjustment, to supply power. Therefore, this imbalance between power supply and consumption can lead to power oversupply or undersupply. Smart grid systems can flexibly store and regulate power to address these issues. A smart grid system stores power in times or areas of surplus and supplies it to times or areas of power shortage. One of the key components for building these smart grid systems is the energy storage system for power storage. Furthermore, with the recent commercialization of electric vehicles, energy storage systems can also be utilized in facilities for charging electric vehicles, such as charging stations.

[0005] Such energy storage systems may include multiple battery containers. The number and arrangement of battery containers may vary depending on various environments and requirements. To address these requirements, there is a growing need to configure battery containers as a combination of small modules to improve energy density and to enable expansion into various configurations.
