Battery Energy Storage System Cooling Solutions: Liquid Cooling VS Air Cooling
Battery Energy Storage System Cooling Chiller is a device used in battery thermal management. Common cooling methods in battery thermal management include air cooling and liquid cooling. So, do you know the difference between these two cooling methods?
There are two thermal management methods for lithium battery units, air cooling and liquid cooling have their own characteristics. Battery Energy Storage System Cooling Chiller can be highly integrated with the battery pack, easy to install on site, occupies a small area, and there is no need to worry about dust, water vapor condensation and other issues. In the case of thermal runaway precursors, the liquid cooling solution can rely on a large flow of cooling medium to force the battery pack to dissipate heat and realize heat redistribution between battery modules, which can quickly avoid the continuous deterioration of thermal runaway and reduce the risk of runaway. The air cooling system has the characteristics of simple system, low manufacturing cost, and easy installation. It is widely used in scenarios where the battery energy density is low and the charging and discharging speed is slow.
1. Under the same inlet temperature and harsh wind speed and flow rate, the temperature of the liquid-cooled battery pack should be 30-40°C, while the temperature of the air-cooled battery pack should be 37-45°C. Liquid-cooled Battery Energy Storage System has better temperature uniformity.
2. In order to achieve the same average battery temperature, air cooling requires several times higher energy consumption than liquid cooling. Under the same power consumption, the temperature of the battery pack is higher for air cooling than for liquid cooling. Liquid cooling consumes less power.
3. Due to factors such as air specific heat capacity and small convective heat transfer coefficient, the heat transfer efficiency of battery air cooling technology is low, and the heat generated by the battery increases, which will lead to excessively high battery temperature and the risk of thermal runaway; the liquid cooling system can greatly reduce the thermal runaway of the battery risk.
4. The liquid cooling system is easier to ensure that the battery works at a comfortable temperature. Compared with the air cooling system, the battery life will be extended, and the investment in liquid cooling is less in terms of the overall life cycle.
The air cooling system has the advantages of small initial investment, low maintenance cost, and easy maintenance. It is more suitable for small civilian or commercial battery thermal management. However, Battery Energy Storage System Cooling Chiller has gradually become a suitable battery cooling method in large-capacity and high-energy-ratio fields such as large ground power stations.
