Recently, the energy storage industry has been competing on battery cell capacity. However, a veteran in the Chinese telecommunications industry has incorporated computer room heat dissipation technology into the battery storage container. Let's take a look.
The cooling of communication base stations and the cooling of energy storage containers are essentially the same battle. Engineer Huijue pointed at the liquid-cooled energy storage cabinet being tested in the Fengxian factory and said.
As an enterprise that has been deeply engaged in communication equipment for over 20 years, Huijue has long mastered the liquid cooling technology for base stations to perfection. When their peers were blowing fans at batteries vigorously, they directly transplanted the "thermal conductive filler + microchannel liquid cooling" technology from the communication field to the energy storage scenario - the temperature difference of the battery cells was directly reduced to ≤2℃, a reduction of more than 30% compared to the industry average.
Even more impressive is the prefabricated cabin design. The on-site assembly of traditional energy storage containers often takes several weeks. The 40-foot battery storage container from Huijue is integrated with BMS, liquid cooling pipes and fire protection systems upon leaving the factory. It can be used immediately after being lifted and powered on on site, shortening the construction period by 50%.
Heat absorption by thermal conductive filler: High thermal conductivity phase change materials are pre-embedded at the bottom of the battery compartment, which instantly absorb the heat from the battery cells. After a power outage, the temperature rise of the box does not exceed 5℃ within 6 hours.
Dual-circulation liquid cooling pipeline: The refrigerant circulates in a closed pipeline, combined with an intelligent temperature control algorithm. The heat dissipation efficiency is 20% higher than that of traditional air cooling - equivalent to adding 15% more battery cells to the same volume.
Dust-proof and rain-proof design: Top deflector plate + five-blade axial flow fan, still effectively dissipates heat in rainy days, completely saying goodbye to the "power guzzler" mode of air conditioning cooling
The actual measurement data speaks for itself: A wind farm project in Northern Europe shows that the attenuation rate of Huijue liquid-cooled energy storage containers is less than 1.5% in an environment of -40℃, and the system efficiency is over 92%, directly outperforming local competitors.
In early 2024, 100 Huijue 1MWh/1C liquid-cooled containers were dispatched to Northern Europe. What surprised the client the most were his three abilities:
Anti-freezing: In extremely cold conditions of -40℃, the lead-acid battery will break down long ago due to a sudden drop in capacity
Anti-spread: Dual temperature control of liquid cooling pipes and phase change materials, zero spread of single cell failure
Anti-dry burning: The intelligent fire protection system is linked with hydrogen exhaust devices, with a protection level starting from IP45
"Communication equipment requires stable operation for 7x24 hours. We directly replicated the same safety standards to the energy storage cabinet." " The product director of Huijue pointed to the NTC independent detachable module inside the cabinet door and said, "The battery cell can be plugged and unplugged within a hundred seconds, reducing the downtime due to faults by 80%."
A certain automobile factory in Jiangsu Province did the math:
Electricity bill savings: Peak shaving and valley filling strategy + efficient heat dissipation, monthly electricity bill reduced by 30% directly;
Operation and maintenance revolution: Remote monitoring system alerts for faults, and worker training time is compressed from two weeks to three days.
Lifespan bonus: Temperature difference control extends the lifespan of battery cells, reducing the need to replace the battery pack once every five years.
The cost reduction magic of prefabricated cabins: Integrated design reduces installation costs by 30% and increases operation and maintenance response speed by 50% - The remote diagnosis experience in the communication industry is now being monetized crazily in battery storage container.
When the industry was obsessed with kilampere-hour battery cells, Huijue proved with its communication genes that heat dissipation efficiency is the hidden track for Battery storage containers.
Liquid cooling technology reduces energy consumption by 20%, prefabricated cabins shorten construction periods by 50%, and intelligent operation and maintenance reduce downtime by 80% - these "communication black technologies" hidden behind the parameter table are reshaping the economic model of energy storage.
Just as a Nordic customer commented: "Chinese people always turn 'impossible' into a standard procedure." From Fengxian, Shanghai to the Norwegian fjords, this miraculous attack of liquid cooling technology has only just begun
