Efficient Cooling System Design for 5MWh BESS Containers:
Discover the critical role of efficient cooling system design in 5MWh Battery Energy Storage System (BESS) containers. Learn how different liquid cooling unit selections impact
The 5MWh liquid-cooling energy storage system comprises cells, BMS, a 20'GP container, thermal management system, firefighting system, bus unit, power distribution unit, wiring harness, and more. And, the container offers a protective capability and serves as a transportable workspace for equipment operation.
The system also features a DC voltage range of 1,081.6 V to 1,497.6 V. From ESS News China-based rolling stock manufacturer CRRC has launched a 5 MWh battery storage system that uses liquid cooling for thermal management.
The liquid-cooling system in the CPS Power Block 5-MWh container uses a multi-level system control. “It utilizes cooling pipes and pumps that circulate the coolant across every battery module to evenly control the temperature,” he said.
This year, most storage integration manufacturers have launched 20-foot, 5MWh BESS container products. However, each integrator's thermal design varies, particularly in the choice of liquid cooling units, which come in different cooling capacities: 45kW, 50kW, and 60kW.
