Recently, EBST officially launched the upgraded second-generation 505 energy storage axial fan Model A505P.A008. Targeting three core pain points prevalent in the current energy storage cooling industry — uneven air distribution, insufficient protection ratings and low energy efficiency — the product adopts an all-new aerodynamic structural design paired with high-efficiency external rotor motors as its core power unit. It delivers all-round breakthroughs in air volume, static pressure, ingress protection, noise reduction, high-temperature resistance and energy conservation. Tailored for the mid-to-high-end industrial energy storage market, this dedicated cooling solution features high reliability, low power consumption and an extended service life, safeguarding the safe and stable operation of energy storage systems.
Mainstream commercial energy storage axial fans currently on the market suffer from three major drawbacks, which have long restricted the operational safety and increased the O&M cost of energy storage equipment:
Conventional fans feature weak wind gathering capacity and severe airflow diffusion during operation, failing to rapidly dissipate heat generated by lithium battery packs and capacitors. The resultant excessive temperature rise not only shortens the cycle life of batteries, but also triggers potential thermal runaway risks.
Most mainstream industry fans only reach IP54 protection grade. Dust and humid vapor can easily penetrate into fan interiors, causing bearing abrasion, motor insulation degradation and corrosion of metal components, and even leading to circuit short circuits. Such products cannot adapt to complex operating scenarios of energy storage power stations, including desert areas, humid coastal regions and high-altitude zones.
Inefficient conventional fans are plagued by high power consumption, insufficient heat dissipation capacity, loud operating noise and frequent maintenance requirements. Long-term operation boosts power consumption and O&M expenditure of the whole energy storage system. In extreme working conditions, unstable system heat dissipation will further amplify potential safety hazards.
To break the above-mentioned industry bottlenecks, the EBST R&D team has conducted thousands of structural iteration optimizations based on CFD computational fluid dynamics simulation. The brand-new upgraded second-generation energy-storage-dedicated axial fan A505P.A008 is officially launched to fundamentally tackle the long-standing pain points of the energy storage thermal management industry.
The new model A505P.A008 adopts a high-efficiency external rotor motor as its core power unit, positioned for mid-to-high-end industrial energy storage applications. Multiple key performance metrics have achieved leapfrog improvements compared with the first-generation model A505P.A001:
It features an aerodynamic design combining forward-swept blades with blade tip winglets. Forward-swept blades reduce airflow separation, while tip winglets curb tip vortex losses. Comparative fluid simulation cloud diagrams clearly demonstrate scattered airflow generated by the first-gen fan, whereas the second-gen model delivers drastically enhanced wind concentration with directional, concentrated air supply. It rapidly dissipates heat from energy storage equipment, stabilizing the temperature difference of energy storage cells at ≤5°C, eliminating localized high-temperature heat islands and significantly extending the service life of lithium batteries.
The maximum air volume reaches 9055 m³/h, and the air volume at the high-efficiency operating point hits 6810 m³/h, representing a 20% improvement over the first-generation model. The ventilation and heat dissipation efficiency of large-area energy storage cabins is doubled.
Its maximum static pressure is 720 Pa, and the stable operating static pressure range is expanded to 0~350 Pa, a 40% increase compared with the 250 Pa upper limit of the previous generation. The powerful air pressure easily penetrates narrow heat dissipation fins of PCS and intricate pipeline air ducts, enabling the energy storage converter to operate at 110% overload without power derating.
Boasting outstanding high-temperature resistance, the fan can run stably for a long time under an ambient temperature of up to 75°C, making it suitable for the sealed high-temperature operating environment inside energy storage cabins.
The maximum overall operating efficiency of the unit reaches 43.2%, a 7.6% improvement from the 35.6% of the first-generation model, hitting an industry-leading level. It also fully complies with the top energy efficiency class requirements of the EU ERP 2026 regulation. Under identical heat dissipation operating conditions, the unit power consumption is greatly reduced, which can substantially cut electricity costs for energy storage stations during long-term operation with prominent green and low-carbon advantages.
The fan’s protection rating has been fully upgraded from conventional IP54 to IP55. It effectively prevents dust, rainwater and high-humidity vapor from infiltrating the unit, eliminating failures such as bearing abrasion caused by dust accumulation, motor insulation breakdown, metal corrosion and circuit short circuits. It is perfectly applicable to all kinds of outdoor energy storage stations including humid coastal areas, sandy Gobi deserts, and high-altitude regions with drastic temperature fluctuations.
Equipped with newly widened blades and exclusive serrated noise reduction structures, the optimized unit achieves an operating noise level as low as 79 dB, 4 dB lower than the first-generation product. While maintaining powerful heat dissipation performance, it alleviates noise issues within energy storage areas.

This upgraded version features simultaneous improvements to multiple hardware structures: widened blades for higher air output, newly added serrated noise-reducing edges on blades, upgraded integrated motor mounting plates, and revised fluid parameters for rear guide vanes. The full unit structure balances easy assembly and mechanical strength, delivering a markedly lower failure rate and cutting the frequency and cost of subsequent equipment maintenance.
EBST 2nd-generation A505P.A008 axial fan is tailor-made for the energy storage sector with strong adaptability to diverse application scenarios:
1.Primary heat dissipation for energy storage battery cabins Compatible with liquid-cooled and air-cooled energy storage systems. It delivers balanced cooling via forced air convection, precisely controls cell temperature differences, and safeguards safe battery charging and discharging.
2.Precision cooling for PCS boost cabins Designed for narrow, enclosed heat sources including IGBT power modules and dry-type transformers. Its high static pressure generates directional jet cooling through fin gaps, ensuring stable full-load output of power converters.
3.Energy storage projects under extremely harsh conditions Suitable for desert energy storage stations with ambient temperatures exceeding 45°C and plateaus above 3,000 meters above sea level. To counter air volume attenuation caused by thin air, a 20%–30% performance margin is reserved during model selection, delivering consistent cooling capacity without performance degradation.
Meanwhile, a lightweight new model A450P.A002 from the same series is unveiled at this launch event to expand cooling options for medium- and low-power energy storage systems. This model features an air volume of 7405 m³/h, operates stably at ambient temperatures up to 70°C under low static pressure conditions of 0–150 Pa. It enriches EBST’s portfolio of energy storage fans and addresses differentiated cooling requirements of energy storage projects with various capacities.
Moving forward, EBST will continue to ramp up investment in R&D for energy storage heat dissipation technologies. Centered on the cooling demands of diverse scenarios, including long-duration energy storage, residential energy storage, industrial & commercial energy storage, and grid-side energy storage, we will launch more high-efficiency, intelligent, and customized fan products. With robust heat dissipation technologies, we will support the safe, efficient, and low-carbon development of the new power system.
