Constructed from high-strength 7075-T6 aluminum via a combination of extrusion and CNC machining, this casing balances lightweight design with exceptional impact resistance and thermal conductivity. The modular structure features internal partitions for cell isolation, integrated liquid-cooling channels, and flame-retardant thermal interface materials (TIMs) to ensure safe, efficient operation.
The casing undergoes a multi-step surface treatment: first, anodizing for corrosion resistance, followed by a ceramic composite coating that enhances fire resistance (UL94 V-0 rating) and electrical insulation. Pressure relief valves and gas diffusion layers prevent thermal runaway propagation, while ultrasonic welding ensures leak-proof seals for liquid-cooled variants. Rigorous testing includes 针刺试验 (GB/T 31485), thermal shock (-40°C to +85°C, 100 cycles), and drop testing (1m onto concrete), meeting global safety standards for lithium-ion batteries.
Battery Safety First: Designed to contain thermal runaway events with flame barriers and gas evacuation channels, reducing the risk of explosions or fires.
Optimized Thermal Management: Liquid-cooling channels (3mm diameter) enable uniform temperature distribution (ΔT < 5°C across cells), improving cycle life by 20%.
Structural Efficiency: Honeycomb core reinforcements increase torsional stiffness by 40% compared to solid aluminum, while weight remains 50% lighter than steel casings.
Electrical Insulation: Dielectric strength of 15kV/mm between internal components, with grounding buses for static discharge protection (ESD: ±15kV air discharge).
Scalable Design: Modular segments allow easy adaptation to different battery chemistries (NMC, LFP, solid-state) and pack sizes (20kWh to 1MWh).
Electric Vehicles: Houses battery packs in EVs, PHEVs, and e-buses, providing crash protection and thermal control during fast charging.
Energy Storage Systems: Used in utility-scale ESUs and residential battery walls, resisting cyclic loading and outdoor environmental factors.
Charging Infrastructure: Encloses power electronics in DC fast chargers (50kW-350kW), managing heat from high-current components and protecting against vandalism.
Unmanned Systems: Lightweight casing for drone and eVTOL batteries, enabling longer flight times through reduced payload weight.
Q: Does the casing comply with UN 38.3 for lithium battery transportation?
A: Yes—all casings used for battery packs meet UN 38.3 requirements for vibration, shock, and temperature cycling during transit.
Q: Can the liquid-cooling channels be customized for specific flow rates?
A: Absolutely—channel geometry (pitch, depth, bend radius) is optimized using computational fluid dynamics (CFD) to meet your target flow rate (0.5L/min to 10L/min).
Q: What is the fire resistance rating of the casing?
A: The ceramic coating achieves a UL94 V-0 rating at 1.5mm thickness, with a peak heat release rate (pHRR) < 500kW/m² as tested per ISO 5660-1.
Q: How is the casing bonded to battery cells?
A: We use high-temperature structural adhesives (service temp: -50°C to +180°C) with shear strength > 25MPa, ensuring reliable mechanical and thermal bonding.
