New energy accessories-battery casing
Key words:
Product Description
In new energy vehicles and energy storage systems, the battery housing is not only a protective barrier for the battery pack, but also a key component to ensure its efficient heat dissipation and stable operation. New energy accessories - battery housing (model: 46×128.2mm) provides high-reliability packaging solutions for battery modules with 0.02mm processing accuracy and multiple process composite manufacturing capabilities, helping the new energy industry move towards higher safety standards.
Core advantages: dual guarantees of precision and strength
Micron-level precision control
Through precision processing technology, combined with lathe and bench work, the key mating surfaces of the battery housing (such as sealing grooves and mounting holes) have an accuracy of ±0.01mm, ensuring seamless assembly with the battery module and avoiding sealing failure or uneven heat dissipation caused by dimensional deviation.
High-strength and lightweight design
The shell is made of high-strength aluminum alloy, and the structure is optimized by CNC processing. The lightweight goal of 1.35kg is achieved in a compact size of 46×128.2mm:
- Topological optimization weight reduction: redundant materials are removed through finite element analysis, and the weight is reduced by 25%;
- Thin-wall strengthening process: the wall thickness of the key load-bearing area is 2.5mm, and the compressive strength reaches 300MPa after heat treatment, which can withstand the expansion stress during battery charging and discharging.
Long-lasting protective coating
The surface is treated with hard chrome plating, with a coating thickness of 15-20μm and a hardness of HV 800-1000. It has wear resistance, corrosion resistance and oxidation resistance, which can effectively resist electrolyte leakage or erosion in a humid environment and extend the service life of the battery pack.
Manufacturing process: Multiple processes work together to create high reliability
From blanks to finished products, the manufacturing of battery shells covers three core processes:
- Lathe processing: Use carbide tools to complete the rough processing of the substrate to ensure dimensional consistency;
- CNC milling: Fine milling of sealing surfaces and heat dissipation fins, with a surface roughness of Ra 0.8μm, to improve heat dissipation efficiency;
- Fixer manual trimming: Remove microscopic burrs to ensure that the assembly surface has no scratches or defects
Protect energy with precision and empower the future with quality - new energy accessories-battery shells, provide hard-core protection for every piece of green power.
