Containerized Energy Storage System

SCU integrates the Standardized Battery Modules, the Battery Management System (BMS), the Power Conversion System (PCS) and Energy Management System (EMS) to build a large containerized battery energy storage system. The 20ft container features a 614 kWh 250kW power storage system, which can be built almost anywhere due to the prefabricated design, therefore, much time and money involved in the process will be saved. The control system of voltage and frequency regulation can help meet the emergency demand for power supply. With module integrated design for fast installation and easy maintenance, the internal protection mechanisms will ensure a safe and sound operation of battery system; our battery system can meet different energy storage demand across a variety of scenarios through flexible combination. They would still work well under such bad conditions as low temperatures and high altitudes.

PCS Power Storage Converter

Bidirectional AC / DC converter can convert DC into AC and AC into DC. Additionally, it can also convert AC into DC to charge battery and convert DC into AC to provide power to loads or back feed the grid.

Battery Modules

The battery system is composed of safe, efficient and long-lasting lithium iron phosphate cells that are connected in series, many of which are further connected in series to form a battery bank.

Battery Manage System (BMS)

The battery manage system can effectively protect the battery against over-charge, over-discharge and overcurrent. Meanwhile, the balanced management of the cells can ensure a safe, reliable and efficient operation of the whole system.

Monitoring System

The system monitors the status of each battery cell and records the historical performance of those cells.

Air-Conditioning System

A 12-KW air-conditioning system is equipped to maintain an optimal temperature for prolonging the service life of battery system.
The battery system complies with the standard of IP54 rating.

Application

• To meet industrial and commercial demand management, peak shaving
• To serve as backup power
• To conduct peak shaving during high power demand periods and valley filling during off-peak hours
• To store power and regulate voltage peak and frequency
• To form a microgrid system

System Topology

Safe and Reliable

• High quality LFP battery cells
• An air-conditioning battery system is in place to ensure optimal temperature for operation of the battery.
• The battery module is equipped with an automatic fire alarm system and in case a fire breaks out, the system would generate an alarm signal.
• The battery system can be equipped with a webcam as required.
• The IP54-class protection helps the energy storage system operate normally under severe conditions.
• Serially designed PCS and battery pack eliminates circulating current to protect the battery system.
• The battery is supported by BMS, PMS and PCS system.

Efficient and Convenient

• Thanks to containerized structure, the battery system is easy for installation and maintenance.
• Stock available for quick delivery
• Remote monitoring of battery’s current, voltage, temperature, SOC, device status.

Lower Cost

• Grid-connected and off-grid power supply
• Peak shaving and valley filling of power consumption
• Harmonic suppression is available in the system to promote a more balanced 3-phase power
• Longer service life, less failures and lower cost of maintenance.
• Wind and solar energy is used to help cut the cost of electricity.
