Focusing on Energy Storage Systems - Forced Air Cooling Technology VS Liquid Cooling Technology (Part 2)
Previously:
Due to the thermal characteristics of batteries, thermal management has become a critical component in the electrochemical energy storage industry chain. Breaking down the value distribution within the industry chain, the cost of batteries in energy storage systems accounts for approximately 55%, PCS accounts for about 20%, BMS and EMS together make up about 11%, while thermal management constitutes about 2%-4%. Although the proportion of thermal management in terms of value is relatively low, it plays a crucial role in ensuring the continuous and safe operation of energy storage systems.
Currently, there are two main mainstream solutions for thermal management technology in energy storage systems, namely forced air cooling system and liquid cooling system. This article will be divided into two parts to provide a comparative analysis of these two cooling systems in terms of lifespan, temperature control, energy consumption, design complexity, space utilization, noise, production & installation, after-sales, operation and maintenance, and cost.
The Part 2 mainly makes a comparative analysis on 5 aspects of noise, production and installation, after-sales, operation and cost.
In the Part 2, a comprehensive comparative analysis will be conducted across five key areas: noise, production & installation, after-sales service, operation & maintenance, and costs.
Explanation of nouns
Thermal management technology: Including forced air cooling, liquid cooling, heat pipe cooling, and phase-change cooling, with the last two still in the experimental stage.
Forced air cooling: The main components of the air cooling system include air conditioning, air ducts, and module fans. The fans are installed at the front of the module. The module fans dissipate the heat generated by the module's internal cores and carry it out to the prefabricated cabin air duct. The air conditioning system inside the prefabricated cabin dissipates heat through convective heat transfer.
Liquid cooling: Liquid cooling system refers to the use of liquid as a heat-conducting medium, transferring heat directly or indirectly by coming into contact with cooling liquid and heat-generating components. It is a heat dissipation technique that removes the heat generated by the heat-generating components.
Chapter Six: Noise comparison
1. System noise comparison of similar manufacturers
2. Comparison of measured noise
Measured noise data of EnerArk in laboratory: 71.8dB at position 1, 68.1dB at position 2, 67.9dB at position 3 and 69dB at position 4;
Field noise measured data at customer A's project site: Maximum 72.8 dB.
（1）The main noise source of forced air cooling: PCS < 75dB, fan < 60dB, air conditioner < 65dB;
Liquid cooling main noise source: PCS < 75dB, liquid cooling unit < 75dB;
（2）There is no obvious advantage in the noise comparison of liquid-cooled and forced air-cooled products, and the basic noise is less than 75dB.
Chapter Seven: Production & installation comparison
2. Comparison & analysis of forced air cooling VS liquid cooling in production and installation:
Liquid cooling is more complex than the forced air cooling in production and installation, and the overall installation work requires more time than air cooling system.
Chapter Eight: After-sales service comparison
1. Comparison & analysis of fault points for the forced air cooling VS liquid cooling:
2. Comparison & analysis of failure points for the forced air cooling VS liquid cooling:
3. The difference of battery PACK after-sales service:
(1) Regarding the after-sales service of the battery PACK, the workload, the number of tasks, and the difficulty of the steps for forced air cooling differ significantly from the liquid cooling system, with the forced air cooling presenting a clear advantage.
(2) Preliminary estimates indicate that, excluding the battery PACK component, the disassembly and assembly time for air-cooled battery PACK is within 20 minutes, while the time control for disassembly and assembly of liquid-cooled battery PACK is set at 2h+.
Chapter Nine: Operation & maintenance comparison
1. Forced air cooling and liquid cooling system maintenance contents and cycle:
(1) The maintenance workload for the forced air cooling system is relatively low, with a longer maintenance cycle and lower labor costs and travel expenses.
(2) The maintenance workload for the liquid cooling system is higher, with a shorter maintenance cycle. It involves more operational steps and precautions, demanding a higher level of experience and qualifications from the operations and maintenance personnel. Specialized knowledge and skills are required, and at times, collaboration with personnel from the liquid-cooling unit manufacturer may be necessary.
2. Maintenance requirements for forced air cooling and liquid cooling systems include:
(1) The forced air cooling system has relatively low requirements for maintenance equipment,

It is a heat dissipation technique that removes the heat generated by the heat-generating components.
Chapter one: Life span comparison
Taking brand A 100Ah (P1, P2) and brand B 100Ah (P3) as examples, with 0.5C charge and discharge, the battery attenuation curve is shown below:
1. The attenuation curve from P1 to P2 shows that at 25°C, 6500 cycles at 80% EOL were achieved with brand-A cells, while at 45°C, 2500 cycles at 80% EOL were achieved with the same brand A cells. With a temperature increase of 20°C, the cycle life decreased by 4000 cycles.
2. P3 mainly reflects 5000 cycles at 80% EOL at 25°C (brand B cells) and 2000 cycles at 80% EOL at 45°C (brand Bcells). With a temperature increase of 20°C, the cycle life decreased by 3000 cycles.
3.Finally, from P4—comparing the service life of main components, it can be concluded that the service life of key components in the liquid cooling system is shorter. The operating temperature of the cells has a significant impact on their cycle life, and as the battery's operating temperature increases, the number of cycles decreases accordingly.
Chapter 2: Temperature control comparison
Summary:
1. During the operation of the forced air cooling system (EnerArk2.0) , the temperature of the battery is approximately 31-38°C. For the liquid cooling system, referring to the Manufacturer A (30°C), Manufacturer B (30°C), the optimal operating temperature for normal batteries is 30-35°C. It can be seen that in terms of battery operating temperature, the forced air cooling has similar advantages to liquid cooling technology.
2. Liquid cooling system temperature differences: Manufacturer A (<5°C), Manufacturer B (<3°C). The temperature difference for the forced air cooling system (EnerArk <7°C). If there is a significant difference in the working temperature of the battery cells, the consistency of the battery cells will deteriorate. Air cooling can achieve a temperature difference of <4°C (EnerArk2.0 target value) by improving the air duct, then the effects of forced air cooling and liquid cooling on the battery would be the same.
Chapter 3: Energy consumption comparison
Take Envicool with the same cooling capacity of 3kW as an example:
Summary:
1. Comparing the heat exchange capacity, it can be seen that the liquid cooling system has 6 times the heat exchange capacity of the forced air cooling system. This can be understood as the air conditioning working at full cooling capacity for 6 hours, while the liquid cooling unit only needs to operate for 1 hour to achieve the same cooling effect.
2. Under the condition of equal battery temperature, for example, starting work at 20°C, after running under the same conditions for 2 hours, even if the system stops charging and discharging, the forced air cooling system still needs to continue working for refrigeration to ensure that the core temperature tends to the normal value. The time for the liquid cooling system to approach the normal value is 1/6 of that of the air cooling system.
3. Forced air cooling power consumption: air conditioning + electrical cabinet fan; Liqu
