Vätskekylsystem för Battery Energy Storage Systems (BESS)

Setrab erbjuder en modulär kylardesign för BESS-applikationer. Vårt vätskekylsystem representerar en toppmodern lösning som ger pålitlig, effektiv och kostnadseffektiv termisk hantering för att förbättra prestanda, säkerhet och livslängd för Li-ion batterier, vilket säkerställer den övergripande prestandan för energilagringsprojekt.

Vårt standard produktsortiment erbjuder kylare med varierande kapacitet från 8 kW upp till 60 kW, och vår interna ingenjörsavdelning kan hjälpa till att anpassa en lösning för varje specifik applikation.

De tekniska kraven tas fram i samarbete med kunden och i denna process kan vi erbjuda bland

  • Analys av värmeavledning
  • Analys av tryckfall och temperaturfält i kylmediet med hjälp av CFD
  • Formningssimulering för tillverkningsbarhet
  • Analys av växlande tryck och vibrationer

The integration of liquid cooling system ensures efficient heat dissipation from the Li-ion batteries. This helps maintain optimal operating temperatures, mitigating the risk of thermal runaway and extending the overall lifecycle of the batteries.

Air cooling systems often result in uneven temperature distribution across battery cells. An air to liquid cooling system achieves superior cooling uniformity by leveraging a coolant’s ability to reach and dissipate heat from hotspots. This ensures consistent performance and minimizes the likelihood of hotspots compromising battery safety.

Li-ion batteries, especially in BESS applications, generate significant heat during charging and discharging cycles. Liquid cooling enables a higher heat dissipation capacity compared to Air Cooling System. This capability is crucial for managing peak loads and maintaining the batteries within the optimal temperature range.

The Liquid Cooling System is designed for energy efficiency, as it optimizes the cooling process based on the actual thermal demands of the batteries. By avoiding overcooling and reducing energy consumption, our solution contributes to operational cost savings over the lifecycle of the BESS.

The integration of cooling method in a single, compact design allows for efficient space utilization. This is particularly advantageous in applications where available space is limited, enabling the deployment of larger battery capacities without compromising on cooling efficiency

Our cooling system is designed with adaptability and scalability in mind. It can be customized to accommodate varying battery configurations and be easily scaled to meet the evolving needs of BESS installations. This adaptability ensures compatibility with different Li-ion battery chemistries and form factors.
