Liquid-cooled battery energy storage systems provide better protection against thermal runaway than air-cooled systems. “If you have a thermal runaway of a cell, you’ve got this massive heat sink for the energy be sucked away into. The liquid is an extra layer of protection,” Bradshaw says.
Overview of a variety of liquid-cooled TEC-Based techniques and their integration into battery thermal management. Compared to using solely liquid cooling, the suggested approach achieved around 20 °C lower in the 40 V test. Battery cell temperatures remained below 40 °C due to liquid cooling circulation.
The implications of technology choice are particularly stark when comparing traditional air-cooled energy storage systems and liquid-cooled alternatives, such as the PowerTitan series of products made by Sungrow Power Supply Company. Among the most immediately obvious differences between the two storage technologies is container size.
Luo et al. achieved the ideal operating temperature of lithium-ion batteries by integrating thermoelectric cooling with water and air cooling systems. A hydraulic-thermal-electric multiphysics model was developed to evaluate the system's thermal performance.
Due to their high thermal conductivity and specific heat, liquid cooling systems are particularly effective for large battery packs and high discharge rates [101, 102]. These systems utilise fluids such as water or oil to effectively manage heat.
Edina, an on-site power generation solutions provider, today (26th April) announce the launch of its battery energy storage system (BESS) solution integrating liquid-cooling system technology, which reduces energy consumption by 30 per cent compared to air-cooled systems.
