The difference between air-cooled energy storage lithium batteries and liquid-cooled energy storage lithium batteries

Air-cooled lithium batteries and liquid-cooled lithium batteries are becoming more and more popular as energy storage systems. What is the difference between them? Let's talk about the main differences today

Heat dissipation method

‌1 Air-cooling takes away heat through air flow, and depends on ambient temperature and air circulation efficiency, and the heat dissipation effect is easily disturbed by external factors. ‌

2 Liquid cooling ‌Dispersing heat through liquid circulation and directs to the heat source, with a thermal conductivity efficiency of 25 times that of air, and is more accurate in temperature control, which can quickly conduct heat and reduce the risk of thermal runaway.

Applicable scenarios

‌1 Air cooling is suitable for medium and low power scenarios (such as industrial refrigeration, communication base stations) and environments with relatively stable temperatures. ‌

‌2 Liquid cooling‌ is more suitable for high energy density, fast charging and discharging scenarios (such as large-scale energy storage projects), and is more stable in high temperature, high humidity or high altitude environments.

Cost and power consumption

‌1 Air cooling‌Initial investment and maintenance costs are low, but operating power consumption is usually lower than liquid cooling. ‌

‌2 Liquid cooling‌ has high initial investment, and the coolant needs to be tested regularly, but the operating power consumption is high.

Therefore, it is usually recommended that household energy storage systems or small industrial and commercial energy storage systems be air-cooled
