What material is used for outdoor energy storage power supply shell?

The material selection of outdoor energy storage power supply shell needs to take into account performance, cost and manufacturability.

Here are some commonly used materials:

(1) Aluminum alloy:
Because of its lightweight, good processability and low cost, aluminum alloy has become the preferred material for energy storage power supply shell. In addition, aluminum alloy also has excellent electromagnetic shielding performance, which can protect the energy storage power from electromagnetic interference. However, aluminum alloys may not have the same strength and corrosion resistance as stainless steel.

(2) Stainless steel:
Stainless steel has high strength, corrosion resistance and good aesthetics, making it an advantage in the manufacture of energy storage power supply enclosures. However, the cost of stainless steel is higher and the weight is larger, which may not be suitable for application scenarios with strict requirements on cost and weight.

(3) Engineering plastics:
Engineering plastics have the advantages of light weight, good insulation, easy processing and low cost. In the manufacturing of energy storage power supply shell, engineering plastics are often used to manufacture battery covers, battery brackets, cable connectors and other components. Some engineering plastics also have excellent corrosion resistance and high strength, which can adapt to the erosion of various environmental factors.

(4) Composite materials:
Composite materials are composed of two or more kinds of materials and have excellent comprehensive properties. In the manufacturing of energy storage power supply shell, composite materials can be used to manufacture large brackets, guides and other components, which can meet complex structural design and higher strength requirements. Common composite materials include glass fiber reinforced plastics (GFRP), carbon fiber reinforced plastics (CFRP) and metal matrix composites.

(5) Other materials: can be used for the manufacture of energy storage power supply shell, such as titanium alloy, high molecular weight polymer, etc.

Material selection needs to consider the following factors: mechanical properties of the material, chemical stability, electromagnetic shielding performance, cost and manufacturability.

According to the actual application scenario and use environment, choosing the most suitable material can improve the performance, reliability and life of outdoor energy storage power supply, but also reduce the cost.
