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
