The MW level containerized battery energy storage system has functions such as mobility, strong flexibility, expandability, and disassembly, which have certain practical value from both commercial and technical perspectives. In addition, it has advantages in the military field and environmental adaptability. Its main features include the following:

(1) Modular design: The International Organization for Standardization has standardized dimensions that allow for convenient ocean and road transportation. They can be hung on overhead cranes, ships, trucks, and temporary land.

(2) Durable design: The International Organization for Standardization protects goods during transportation and will provide good protection from weather, transportation, and other environmental factors throughout the lifespan of energy storage systems.

(3) Mobility design: Compared to other energy storage batteries, the advantages of lithium battery energy storage technology lie in its quality and volume, strong mobility, and no geographical limitations.

(4) Flexible basic design: Containers are easily adaptable to any desired choice. This includes the connection of air conditioners, photovoltaics, fans, passage doors, power cables, and other equipment.
