What is the industry standard for metal battery box ?

Industry standards and policies and regulations have put forward specific requirements for the manufacturing and use of metal battery boxes, mainly reflected in the following aspects:

 Packaging and transportation requirements
According to the packaging requirements of UN codes (such as 3090, 3091, 3480, and 3481), the packaging must meet the Level II performance level, using sturdy outer packaging, protective shells, or pallets to prevent damage and danger during transportation.

 Material and structural requirements
The manufacturing of metal battery boxes must comply with specific material standards, such as aluminum alloys (such as EN AW 5053) and die-casting molding processes, to ensure their structural strength and durability. At the same time, the battery box needs to have insulation performance to prevent short circuits and electrolyte leakage.

 Safety and Performance Standards
The newly introduced industry standards, such as the "Safety Requirements for Power Batteries for Electric Vehicles" GB 38031-2025, have put forward higher requirements for the performance of battery packs, emphasizing the safety, explosion resistance, and energy density improvement of batteries, and promoting the development of battery packs towards a safer and more efficient direction.

 Regulations and Compliance
The manufacturing and use of metal battery boxes must comply with transportation industry standards (such as JT/T 617.4-2018) and international transportation regulations (such as 49 CFR § 173.185) to ensure compliance during transportation and use.

 Environmental Protection and Recycling Requirements
The recycling and disposal of waste power batteries must comply with relevant standards (such as the Industry Standard for Material Management (WB)) to ensure the rational utilization of metal resources and environmental safety.
