In energy storage systems (ESS), safety and performance are often discussed in terms of cell chemistry, energy density, or control algorithms. Yet, the foundation of a reliable ESS lies equally in manufacturing precision and quality assurance — especially in thermal management. For Air Cooling ESS (air-cooled energy storage systems), every stage of production — from sheet metal fabrication and assembly to airflow calibration and high-temperature endurance tests — directly influences system lifespan and operational safety.
A robust Air Cooling ESS begins with a structured and tightly controlled production flow. The standard workflow can be summarized as follows:
The cabinet and internal structural parts of Air Cooling ESS are primarily composed of galvanized steel or aluminum alloy plates. Using CNC laser cutting, bending, and stamping ensures dimensional precision and mechanical strength. This stage includes:
CNC laser cutting for high-precision component outlines and ventilation apertures.
Automated bending and forming to maintain consistent angles and panel tolerances.
Surface treatment such as electrostatic powder coating, anti-corrosion spraying, or galvanization to enhance durability.
Proper structural integrity in this stage ensures optimal air channels and mechanical protection for electronic components.
After sheet metal parts are prepared, assembly begins. This involves installation of fans, ducts, control boards, insulation panels, sensors, and wiring harnesses. Modular assembly is often applied:
Cabinet skeleton assembly, ensuring mechanical alignment.
Air duct and cooling module installation, guided by thermal simulation data.
Electrical integration, including busbar and control unit wiring.
Preliminary functional testing, verifying fan rotation, temperature sensor feedback, and BMS communication.
Before shipment, each Air Cooling ESS unit undergoes comprehensive system testing, including performance verification, temperature rise tests, vibration resistance, and insulation checks. This multi-level validation guarantees stable operation across varying environmental conditions.
Fans and air ducts form the core of thermal management in an Air Cooling ESS. Their performance directly affects temperature uniformity, component lifespan, and acoustic comfort.
Fan selection must balance airflow volume, static pressure, noise level, and energy efficiency:
Airflow capacity: Sufficient to maintain uniform temperature distribution across modules.
Static pressure rating: Ensures consistent cooling even with filters and duct resistance.
Noise control: Use of low-vibration bearings and optimized blade geometry reduces acoustic impact in commercial or indoor installations.
Reliability and redundancy: Dual-fan or N+1 configurations prevent single-point failure.
All selected fans typically comply with IEC and ISO mechanical reliability standards, with lifetime ratings exceeding 50,000 hours under continuous operation.
The air duct structure determines the efficiency of heat removal. Computational Fluid Dynamics (CFD) simulation is used in design to ensure airflow balance. Critical parameters include:
Duct geometry optimization to minimize flow resistance and turbulence.
Flow equalization structures to ensure even cooling of battery modules.
Anti-vibration and sealing measures to prevent air leakage or structural fatigue.
High-quality ducts are fabricated with tight dimensional tolerances (±0.3 mm) and undergo fit verification before integration.
The inlet and outlet design of an Air Cooling ESS cabinet dictates the efficiency of thermal exchange.
Manufacturing accuracy of inlet and outlet structures ensures airflow uniformity. Deviation in alignment or aperture size can lead to hot zones within the ESS. Advanced machining centers are employed to achieve:
Hole diameter tolerance within ±0.1 mm.
Edge smoothness for laminar airflow.
Consistent positioning relative to module arrays.
During development, CFD simulation validates the airflow pattern and temperature gradient inside the ESS. Engineers simulate real operational conditions — ambient temperature, internal heat generation, and fan speed — to refine airflow design. Parameters analyzed include:
Velocity vector fields and flow uniformity.
Temperature gradients between modules.
Hotspot risk assessment under full load operation.
Post-production, physical airflow tests using anemometers and thermographic imaging confirm simulation accuracy. This data feedback loop ensures design-to-production consistency.
Electrical reliability is a crucial safety aspect in every Air Cooling ESS unit. Comprehensive insulation and dielectric testing is conducted to ensure safe operation over years of service.
High-voltage insulation testers evaluate insulation resistance between live circuits and enclosure grounding. Standard requirements often exceed 10 MΩ at 1000 VDC.
Each system undergoes a withstand voltage test, applying elevated AC voltage (typically 2500V) to detect insulation breakdown or leakage current.
Ground resistance and leakage current are measured to confirm protective grounding integrity. Automated safety analyzers log all test data for traceability.
All testing follows IEC 62933, IEC 62477, and GB/T 3859 guidelines for energy storage power converters and electrical safety.
This rigorous testing process ensures that every Air Cooling ESS can safely handle both high current and ambient fluctuations without risk of electric shock or failure.
Aging and thermal endurance tests replicate real-world long-term stress to validate reliability.
The assembled Air Cooling ESS operates under controlled conditions for extended hours (usually 72–120 hours). This allows engineers to identify early component failures or unstable connections before delivery.
Systems are placed in climate chambers cycling between -20°C to +60°C, simulating environmental variations. Sensors monitor:
Temperature rise under full load.
Fan RPM stability.
BMS thermal response.
Key parameters (current draw, voltage stability, fan performance) are recorded to verify the ESS’s capacity to maintain continuous cooling performance even under thermal stress.
These aging tests help ensure that Air Cooling ESS units from Dagong Huiyao Intelligent Technology Luoyang Co., Ltd. maintain stable performance through years of service.
Since Air Cooling ESS are often installed outdoors or in semi-exposed environments, Ingress Protection (IP) ratings are essential quality benchmarks.
Cabinet seams, air filters, fan housings, and cable inlets use rubber gaskets and sealing rings to block moisture and particulate ingress. Air filters are rated to block particles above 10 μm.
Certified third-party labs perform:
Water spray and immersion tests for IPX4–IPX5 ratings.
Dust chamber tests simulating windborne dust exposure for IP5X–IP6X.
Typical high-quality Air Cooling ESS achieves IP54 or IP55, balancing sufficient airflow with robust environmental resistance.
Dagong Huiyao’s ESS products undergo full-cycle IP validation to ensure protection in diverse deployment conditions — from arid deserts to humid coastal areas.
Quality consistency is achieved through systematic management and traceability.
Dagong Huiyao operates under ISO 9001 and ISO 14001 frameworks, integrating quality and environmental management in all production lines.
Raw materials (sheet metal, fans, wiring, sensors) undergo dimensional, visual, and electrical checks before entering production. Nonconforming materials are rejected to prevent downstream issues.
Throughout assembly, multiple checkpoints ensure process integrity:
Torque verification for screws and busbars.
Optical inspection of wiring connections.
Real-time temperature monitoring during test runs.
Before shipment, final inspection verifies mechanical structure, insulation strength, airflow uniformity, labeling, and packaging. Test results are archived digitally for after-sales traceability.
This multi-layered system ensures that each Air Cooling ESS delivered meets stringent performance and safety requirements.
