Description

Battery Transfer Apparatus and Energy Storage System Including the Same The present disclosure relates to a battery transfer device and an energy storage system including the same. An Energy Storage System (ESS) is a system capable of storing surplus electricity or electricity produced using renewable energy. By utilizing an Energy Storage System, idle power can be stored during periods of low electricity demand and supplied during periods of high demand, thereby enabling smooth control of power supply and demand. Energy storage systems are formed by stacking multiple battery modules or packs. However, due to the heavy weight of each battery module, handling tasks such as replacement or repair is not easy. Therefore, there is a demand for energy storage systems that facilitate the handling of battery module packs.

FIG. 13 is a perspective view illustrating an example in which a transport device is coupled to the battery transport device shown in FIG. 12. Hereinafter, the present disclosure will be described in detail with reference to the attached drawings. However, this is merely illustrative and the present disclosure is not limited to the specific embodiments described illustratively. FIG. 1 is a schematic diagram of an energy storage system according to one embodiment of the present disclosure. Referring to FIG. 1, an energy storage system (1) according to one embodiment of the present disclosure may include an energy storage device (50) having a loading space (S) in which a plurality of battery modules (10) are accommodated, a battery transfer device (30) for taking out or taking in battery modules (10) from the energy storage device along a first direction, and a transport device (F) for transporting the battery transfer device (30). In describing the present embodiment, the first direction may mean the ±Y-axis direction with respect to FIG. 1, the second direction may mean the ±X-axis direction, and the third direction may mean the ±Z-axis direction. For example, the direction in which the battery module (10) is introduced into the energy storage device (50) may be the +Y-axis direction, and the direction in which the battery module (10) is withdrawn from the energy storage device (50) may be the -Y-axis direction. The energy storage device (50) may include a cabinet (51) having an opening and a door (53) rotatably coupled to the cabinet (51) to close the opening. The cabinet (51) may include a plurality of mounting sections (512) on which battery modules (10) are loaded. The mounting sections (512) may be positioned to partially support the lower portion of each battery module (10), and each battery module (10) may be seated on the mounting section (512) and mounted in the storage space (S). The battery modules (10) may be inserted into the interior of the cabinet (51) along a first direction (Y-axis direction). Accordingly, the mounting sections (512) may also be arranged lengthwise along the first direction. According to one embodiment, the cabinet (51) may further include a partition (513) that divides the internal space into a plurality of storage spaces (S). In this case, a plurality of battery modules (10) accommodated in the storage spaces (S) may be electrically connected to one another. Meanwhile, a plurality of battery modules (10) accommodated in an energy storage device (50) may have a relatively high weight (e.g., 100 kg to 500 kg), making it difficult for a worker to handle them by hand. Accordingly, the energy storage system (1) according to the present embodiment may include a battery transfer device (30) and a transport device (F) for transporting the battery. The transport device (F)
