As a general standard, vehicle batteries must not use metal inner packaging.
The inner packaging must completely enclose each battery or cell as they cannot come into contact with other equipment or any other conductive material. The interior is protected by filling materials with flame retardant, heat insulation and anti-leakage functions. There should not be any leakage due to changes in temperature, humidity or pressure, the surface should be clean and no harmful or hazardous substances should be allowed to adhere.
The inner packaging containing the car battery may be placed in a container made of the following materials that qualify as dangerous goods packaging: wooden, plywood, paper or solid plastic boxes
The protective materials and protection methods used in the outer packaging box should also be compatible with the performance of the power battery, meet the needs of the overall performance of packaging and transportation, and be able to withstand the impact and vibration during transportation to ensure the safety of the power battery and outer packaging during transportation,In such cases, plastic sleeve boxes, plastic pallet boxes, plastic pallets, wooden boxes, and metal turnover boxes are the preferred materials.
For prismatic batteries, the best packaging design should be able to protect the surface of the battery from damage, while also considering how to prevent the battery from moving and being damaged during transportation and storage.
A common prismatic battery packaging design is to use a plastic or metal casing to protect the surface of the battery, and use a lining material to support the battery and prevent it from moving and being damaged during transportation and storage. In addition, some prismatic battery packaging designs include special slots or slots to ensure that the battery is properly aligned and locked during installation. The best prismatic battery packaging design should take into account multiple factors such as battery shape, size, weight, flammability and safety standards, and be able to meet various safety standards and regulations.
In addition to the square battery packaging design mentioned above, there are some other possible packaging designs, such as:
- Use a hard plastic or metal casing filled with shock-proof material to protect the battery’s surface and internal components;
- Use flexible packaging materials, such as polyimide (PI) film, to reduce the weight of the battery and provide a certain degree of waterproofing and dustproofing;
- Use reusable packaging designs, such as removable plastic shells and lining materials, to reduce waste;
- Use recyclable packaging materials such as cardboard or plastic to reduce environmental impact.
Excellent electric vehicle battery packaging design should take into account multiple factors such as battery characteristics, life cycle, cost and environmental impact, and be able to meet various safety standards and regulations.
