Empowering the Future of Clean Energy: Maximize BESS Performance with Advanced Thermal Management
BESS Thermal Mangement for Safe and efficient energy storage
Energy storage is essential for modernizing U.S. infrastructure. It improves grid reliability, lowers energy costs, and maximizes the use of renewable resources like solar and wind. Battery Energy Storage Systems (BESS) play a pivotal role by storing excess energy and dispatching it during peak demand. However, as BESS technologies evolve to handle higher power densities and faster charge/discharge cycles, effective thermal management becomes crucial. Without proper cooling, systems risk thermal runaway, reduced performance, and shorter lifespans.
Thermal Challenges in Battery Energy Storage Systems
Thermal management is more than an engineering task; it is the foundation for safe, reliable, and efficient energy storage. The unique requirements of BESS present several critical thermal challenges.
Heat Generation During Charging and Discharging
BESS operations involve rapid energy flows that generate significant heat. If not managed effectively, this heat reduces efficiency, accelerates battery degradation, and shortens system lifespan. For more on managing heat in BESS systems, see this study on thermal management techniques.
Risk of Thermal Runaway
While lithium-ion batteries offer unmatched energy density, they are vulnerable to thermal runaway. This dangerous chain reaction, where heat builds uncontrollably, can result in catastrophic failures like fires or explosions. Preventing thermal runaway is critical for safety and operational integrity. Learn more about the risks of thermal runaway in lithium-ion batteries in this review.
Thermal Cycling Stress
Frequent charge and discharge cycles lead to constant temperature fluctuations. These fluctuations create mechanical stress on battery components, which accelerates wear, increases repair costs, and raises the risk of unplanned downtime.
Environmental Impacts
BESS installations must function in diverse environments, ranging from freezing cold to extreme heat. Thermal management solutions must adapt to these conditions to ensure consistent performance and safety, regardless of the weather.
ACT’s Proactive Approach to BESS Thermal Management

Environmental Control Units & Chillers
For indirect cooling of secondary BESS components, our rugged Tekgard® ECUs provide precise temperature control, maintaining stable air temperatures even below ambient levels. Scalable from 1 to 12 tons (3.5–42.2 kW), these systems can be customized to meet specific requirements and are built to withstand harsh environments, ensuring reliable and efficient cooling in the toughest conditions. Within this series, the Vaphtek™ model distinguishes itself by offering dual operational modes: standard vapor compression and a Pumped Two-Phase (P2P) eco-mode. This P2P mode, when ambient temperatures permit, efficiently rejects waste heat to the air without compressor usage, minimizing energy consumption.
Similar to our ECUs, Tekgard® Chillers utilize vapor compression to cool a liquid, which is then used for direct cooling of primary BESS components. Typically housed outside the BESS enclosure, these chillers reject waste heat to the ambient air and can be ruggedized and scaled as needed for optimal performance and efficiency.
Two-Phase Cooling Solutions
Optimize your Battery Energy Storage System (BESS) cooling with ACT’s advanced two-phase solutions. Our Pumped Two-Phase (P2P) and Loop Thermosyphon technologies ensure superior heat transfer, precise temperature control, and enhanced battery lifespan.
P2P systems maintain isothermal conditions across battery modules, reducing degradation and maintenance while using a safer dielectric fluid instead of water-based alternatives. Loop Thermosyphons provide a passive, pump-free cooling solution for reliable, low-maintenance operation.
Designed for high performance, safety, and efficiency, ACT’s scalable two-phase solutions enable rapid design cycles while meeting the rigorous thermal demands of the BESS industry.
