Description

Cover for energy storage apparatus and energy storage apparatus including the same The present invention relates to a cover for an energy storage device and an energy storage device including the same. Recently, as issues such as power shortages and eco-friendly energy have come to the forefront, Energy Storage Systems (ESS) for storing generated electricity are receiving more attention. For example, the Smart Grid System is being proposed as one of the measures to regulate power supply and demand. The amount of electricity consumed by consumers is not always constant and can fluctuate frequently. Typically, using such an ESS facilitates the establishment of a power management system like the Smart Grid System, making it easy to regulate power supply and demand in specific regions or cities. Furthermore, as the commercialization of electric vehicles accelerates, such ESS can also be applied to electric charging stations capable of charging electric vehicles. While ESS can be configured in various forms, it is typically configured to include one or more battery containers. A container refers to a configuration designed to store goods internally, and generally refers to a marine container that can be transported by sea as well as by land. In particular, marine containers can have large sizes, such as 20-foot or 40-foot containers. It can be argued that the term 'container' is used because the battery containers included in an ESS have large sizes, similar to these marine containers. A battery container may contain multiple batteries connected in series and/or parallel. Here, the multiple batteries may be stacked and stored using a separate fixed structure, such as a rack frame. In order to increase the energy density of battery containers, it is required to minimize empty space inside the battery containers, and to achieve this, a method is required to more easily install separate fixed structures, such as rack frames, inside the battery containers.
