Containerized energy storage systems (CESS) are advanced, modular solutions designed to store and manage large-scale energy efficiently. These systems are typically housed in standard shipping containers, such as 20-foot or 40-foot ISO containers, making them scalable, portable, and easy to integrate into various energy applications.
Battery Modules:
Usually lithium-ion batteries (e.g., LFP or NMC chemistries).
Alternative technologies like flow batteries or sodium-based systems are also possible.
Battery Management System (BMS):
Monitors and manages battery performance, temperature, and safety.
Inverters and Power Conversion Systems:
Converts electricity between AC and DC as needed.
Thermal Management:
Includes cooling, heating, and ventilation systems to maintain optimal temperature for battery operation.
Energy Management System (EMS):
Software that monitors and optimizes energy flow, scheduling, and usage.
Safety Features:
Fire suppression systems, overcurrent protection, and environmental sealing to ensure safety and reliability.
The capacity range of container energy storage systems is mainly concentrated between 500 kilowatt-hours (kWh) and 1000 kilowatt-hours (kWh), but there are also some larger capacity products with capacities up to 3MWh to 6MWh. The specific capacity can be modularized according to requirements.
The container energy storage system has the characteristics of simplifying infrastructure construction costs, short construction cycle, high modularity, easy transportation and installation, etc., and can be applied to power stations such as firepower, wind energy, solar energy, or islands, communities, schools, scientific research institutions, factories, large load centers and other applications.
The energy storage system needs to be connected to the power network, so there needs to be a reliable power supply. At the same time, it is necessary to ensure that the distance between the power access point and the energy storage system is moderate to reduce transmission losses.
Container energy storage system has certain requirements for environmental conditions. For example, good ventilation and heat dissipation conditions, fire prevention, waterproof and other safety measures.
When installing a container energy storage system, comply with relevant safety regulations and standards to ensure device safety and reliability. And the container energy storage system needs to be repaired and maintained regularly. In addition, the installation of containerized energy storage system first needs to consider the site situation, and the containerized energy storage system needs enough space to accommodate the energy storage equipment. The site should have a smooth and stable foundation, and be able to meet the space required for the installation, maintenance, and operation of the equipment.
Typical Use Cases:
Utility-Scale Energy Storage: Supporting renewable energy penetration and grid stability.
Microgrids: Enhancing energy independence and reliability in remote or islanded areas.
Commercial Facilities: Reducing energy costs and increasing operational resilience.
