Product Introduction

Aluminum battery boxes cover are core protective components for the packaging of new energy lithium-ion batteries. Made of highly adaptable aluminum alloy through precision stamping and welding processes, they are used in battery pack packaging for new energy vehicles and energy storage. Their core functions include sealing and protection, electrode lead-out, and safe pressure relief. They comply with standards such as IEC 62133 and GB/T 31484, meeting the core requirements of engineering procurement, balancing strength, sealing, and safety to ensure the long-term stable operation of the battery pack.
performance advantages
High Toughness and Corrosion Resistance, Stable Structure
Utilizing high-purity 6061/5052 aluminum alloy, with a tensile strength ≥180MPa and hardness ≥50HB, the product exhibits excellent corrosion and fatigue resistance. It can withstand the erosion of complex automotive and outdoor environments, showing no oxidation or deformation, and is not prone to cracking even after long-term use, ensuring the stable protection of the battery pack structure.
Excellent Sealing, Safe and Controllable
Processed with precision laser welding and vacuum welding technology, the welds are uniform and defect-free, achieving a waterproof rating of IP67/IP68 and an airtightness ≤50Pa/min. The product effectively isolates moisture and dust, and integrates an explosion-proof pressure relief valve to precisely control the safety risks of battery pack overvoltage and overheating.
Precise Fit, High Consistency
Based on a standardized production system, dimensional tolerances are ≤±0.02mm, flatness ≤0.03mm/m, and hole positions are precise. The product can be customized in specifications and surface treatments as needed. The overall batch pass rate is ≥99.8%, adaptable to batch assembly and multi-scenario engineering selection requirements.

Main functions
Sealed Protection: Through precision welding and sealing groove design, the battery pack achieves IP67/IP68 waterproof and dustproof ratings, isolating moisture and dust, preventing battery short circuits and bulging. The product ensures long-term stable operation of the battery pack, meeting engineering safety selection requirements.
Structural Support: The aluminum alloy material boasts excellent mechanical strength, serving as a core structural component of the battery pack. It secures the battery modules, resists mechanical stress, and effectively prevents module displacement and damage, providing stable structural support.
Safe Pressure Relief: An optional explosion-proof pressure relief valve is integrated, allowing for rapid pressure relief in case of overheating or overpressure, preventing explosions and ensuring the safety of personnel and equipment. The product meets new energy battery safety standards, reducing safety risks.
Electrode Lead-Out: Precisely designed electrode lead-out holes accommodate electrode lead-out and fixation, ensuring stable conductivity and good insulation, preventing electrode short circuits. The product ensures normal power supply to the battery pack and meets engineering electrical connection requirements.
Auxiliary heat dissipation: Aluminum alloy has excellent thermal conductivity, which can conduct heat from inside the battery pack to the outside, assisting in heat dissipation, preventing performance degradation, extending battery life, and adapting to the needs of high-voltage, high-capacity battery packs.

Packaging and Transportation
To address the unique characteristics of aluminum battery boxes cover products, we employ a multi-layered packaging approach: inner pearl cotton wrapping, outer cardboard box protection, pallet support, and reinforcement with moisture-proof film and cable ties. This effectively prevents product deformation, scratches, and oxidation during transportation, ensuring product integrity. For shipping, we partner with globally renowned logistics companies, offering sea freight, air freight, and express delivery as needed. We provide full tracking of the logistics process to ensure timely and safe delivery to the customer's designated location, minimizing transportation risks.
