The MW level containerized battery energy storage system is based on a 40 foot standard container, equipped with two 250 kW energy storage energy conversion systems. It integrates the 1 MWh lithium battery system, battery management system, energy storage monitoring system, air conditioning system, fire protection system, and distribution system into a specially designed box to achieve high integration, large capacity, and mobile energy storage equipment. It has characteristics such as insulation, constant temperature, fire retardant, and wind and sand resistance, Meet various environmental uses.

The MW level containerized battery energy storage system includes a battery system, battery management system, energy conversion system, and control system. As shown in Figure 3, the black part represents 6 battery clusters in parallel in the battery room, the gray part represents the energy conversion system, air conditioning system, and control system, and the purple part represents the air duct.

(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.
