Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, specifically to an energy storage container. Background Technology

[0002] With the development of the energy storage industry, traditional energy storage boxes usually choose containers as the carrier of energy storage units. However, energy storage systems are complex, and the internal layout space of international standard-sized containers is limited. International standard-sized containers cannot meet the layout requirements of energy storage units, resulting in inconvenience for road, rail and sea transportation.

[0003] Currently, in existing technologies, the battery rack of an energy storage container is designed independently from the container, and the battery rack is connected to the container. For example, Chinese patent CN108807782A discloses a battery rack including a base, a support frame, and a tray. The support frame is fixed on the base and includes a vertical column fixed on the base and horizontal beams fixed end-to-end on both ends of the column. The support frame also includes a load-bearing beam disposed on the column along the tray pushing direction. The column, horizontal beam, and load-bearing beam form at least one battery placement area. The tray is detachably fixed to the upper surface of the load-bearing beam. The tray includes a base plate and rollers. The rollers are disposed on the side surface of the base plate near the load-bearing beam. The tray rolls against the upper surface of the load-bearing beam through the rollers to push the tray into a predetermined position on the battery rack. The battery module and / or high-voltage box are fixed to the other side surface of the base plate. However, this type of battery rack is installed as a whole inside the container, which occupies the internal space of the container, thus affecting the battery placement space and consequently affecting the energy density of the energy storage container.
