5MWh BESS in 40ft container is modular, non-walk-in container is designed for rapid deployment, minimizing both installation and maintenance costs, for utility-scale and commercial & industrial (C&I) applications.
The common 5MWh BESS design is a two-hour energy storage system with a 5.016 MWh capacity. It consists of 12 Battery Racks connected in parallel, integrating a battery management system (BMS), liquid-cooling system, fire suppression system, and environmental control system.
Each rack comprises 52 battery packs connected in series, along with a high-voltage control box. Each battery pack contains 52 lithium iron phosphate (LFP) 314 Ah cells with a voltage of 3.2 V arranged in series. providing high energy density, wide operating temperature range, long lifespan, lightweight construction, and enhanced safety
The battery also includes liquid cooling plates, aluminum serial bars, end plates, an outer shell, a current collection system, and a slave battery module unit.
The system has a size of 6,058 mm x 2,438 mm x 2,896 and its weight ranges from 38,000 kg and 42,000 kg. It operates within temperatures ranging from -30 C to 50 C and supports elevations up to 3,000 meters.
The battery should has a lifecycle of 6000 to 8000 cycles. It relies on liquid cooling and is IP67-rated. Its roundtrip efficiency at begin of life (BOL) is 88%.
