How It Works

A liquid-cooled energy storage container packages battery clusters, power distribution, thermal management and fire protection into one factory-built 20-ft high-cube unit. Liquid cooling circulates coolant past the cells to hold them in their optimal temperature band, which is what allows 5 MWh of LiFePO4 to be packed into a standard container while preserving cycle life. A three-level BMS and dual perfluorohexanone-plus-water fire suppression keep the battery safe across a -20 to 50 °C operating range.

Structure & Composition

Inside the container, twelve 1P416S battery clusters line the two side walls, each cluster made of four 1P104S packs and one high-voltage box. A 60 kW liquid chiller circulates coolant through the clusters, an air-cooled power-distribution and combiner cabinet feeds the auxiliaries, and a perfluorohexanone plus water fire system protects the whole unit. The container uses a steel–rock-wool–steel sandwich construction for more than one hour of fire resistance and IP54 sealing.

Selection Guide

  • Choose 2.5 MW / 5 MWh per 20-ft unit for grid-side and utility storage; parallel units to scale capacity.
  • Select the half-populated 1.25 MW / 2.5 MWh unit for lighter-load C&I peak-shaving applications.
  • Specify IP55 and higher corrosion ratings (C5-H) for coastal or harsh industrial sites.

Frequently Asked Questions

Q

Why liquid cooling?

It holds cell temperature uniform, supports higher energy density and prolongs cycle life — the reason 5 MWh fits a standard 20-ft container.

Q

How much energy does one unit hold?

A single 20-ft unit is 2.5 MW / 5 MWh (5016 kWh at 1331.2 Vdc); the half-populated variant holds 2.5 MWh.

Q

What fire protection is inside?

Combined detectors in each PACK trigger perfluorohexanone at PACK/cluster level, with a water-flooding system as the final containment layer.

Q

What cells are used?

0.5P LiFePO4 cells of 3.2 V / 314 Ah, chosen for thermal stability and long cycle life.
