Lithium-ion Electric Car Battery Pack Shell

Lithium-ion electric car battery pack shell plays an important role in the battery system. It has multiple functions such as protection, support, heat dissipation, corrosion resistance and appearance, providing reliable guarantee for the safe operation and stability of the battery.

Lithium-ion electric car battery pack shell is usually made of aluminum alloy material. The composition and performance of aluminum alloy can be adjusted and optimized according to different application requirements, so it is widely used in industrial manufacturing.
Characteristics of aluminum:

Lightweight: Aluminum is a lightweight metal with a density of approximately 2.7 g/cm³, which is lighter than traditional materials such as steel.

Good electrical and thermal conductivity: Aluminum has good electrical and thermal conductivity and can effectively conduct current and heat, making it suitable for applications that require heat dissipation and electrical conductivity.

Ease of processing: Aluminum alloy has good plasticity and processability, and can be made into products of various shapes and sizes through die-casting, stamping, extrusion and other processing processes.

Corrosion resistance: Aluminum alloy has certain corrosion resistance, but compared with pure aluminum, the corrosion resistance of aluminum alloy is slightly lower, and surface treatment or alloy adjustment is required to improve its corrosion resistance.

Recyclability: Aluminum is a recyclable material with good sustainability and environmental protection, helping to reduce resource consumption and environmental pollution.

Material selection: Excellent aluminum materials are the basis for producing high-level aluminum battery cases. Purchase high-quality aluminum alloy materials suitable for casing manufacturing from aluminum alloy suppliers.

Cutting: Cut the aluminum alloy plate according to the design size of the shell to ensure that the plate size is accurate.

Stamping: Send the cut aluminum plate into the stamping equipment. According to the design drawings and process requirements of the shell, the aluminum plate is shaped and shaped through the stamping die.

Ultrasonic cleaning and drying : After stamping is completed, the shell parts are sent to ultrasonic cleaning equipment for cleaning. Ultrasonic cleaning can effectively remove oil stains, metal shavings and other impurities on the surface of the casing to ensure that the surface of the casing is clean. After cleaning, the shell pieces are placed in an oven for drying to remove moisture and prevent oxidation.

Inspection: Conduct quality inspection on the dried shell parts.

Packaging and shipment: After completing the quality inspection, the qualified shells are classified, counted and packaged. Appropriate packaging materials and methods are usually used to protect the casing from damage and are marked with clear product information. In the end, the packaged shell is packed and shipped, ready to be shipped to the customer.

Technical advantages: Lithium-ion electric car battery pack shell production technology is becoming increasingly mature, using advanced processing equipment and techniques, such as stamping, cutting, ultrasonic cleaning, etc., to achieve high-precision and high-efficiency production. In addition, aluminum materials have good plasticity and are suitable for processing needs of various complex shapes and sizes.
