Containerized Energy Storage System

2500kW 5.016MWh Containerized Energy Storage System

High-Power Energy Storage for Large-Scale Applications

2500kW/5.016MWh liquid-cooled containerized energy storage systems are suitable for large industrial parks, data centers, and other sites with high and continuous power demand. Each 20-foot ESS container provides 5.016MWh of battery capacity and 2500kW of rated power, with up to two hours of full-power discharge. Their high energy density allows large amounts of electricity to be stored within a compact footprint for load shifting, peak shaving, renewable energy integration, and grid support.

Components

Battery System:
The ESS containers use 5.016MWh LFP battery systems designed for high-capacity energy storage. They operate at a nominal DC voltage of 1331.2V, within a range of 1164.8–1497.6V, and support a maximum DC current of 1440A at a 0.5C charge and discharge rate. Under specified conditions, the batteries provide at least 8000 cycles at 90% depth of discharge, with 70% capacity remaining.
Power Conversion System (PCS):
The 2.5MW bidirectional PCS controls charging and discharging with efficiency of at least 95%. Its four-quadrant capability provides flexible power control and allows the battery systems to work with solar PV, wind power, and diesel generators.
Thermal Management System:
Water cooling maintains an even temperature across the battery cells, with differences kept within 3°C. Intelligent control also cuts auxiliary energy use by 30% and keeps the ESS containers operating reliably from -30°C to 55°C.
Intelligent Management System:
AI-based predictive maintenance continuously checks battery health and provides fault warnings with accuracy above 99%. Operators can review operating data from mobile or PC platforms through the cloud management system. The ESS containers also meet IEC 62619 and GB/T 36276 requirements for battery safety and grid-connected energy storage.
