What is the material ratio of outdoor energy storage power supply shell?
In the manufacturing process of outdoor energy storage power supply shell, the material ratio is one of the important factors affecting its performance.
The following briefly introduces 4 kinds of commonly used outdoor energy storage power supply shell materials and their matching schemes:
(1) Aluminum alloy material ratio:
Aluminum alloy is usually 6061 or 6063 and other grades, and its ratio mainly includes aluminum, magnesium, silicon and other elements. Among them, the content of silicon and magnesium has an important effect on the mechanical properties and machinability of aluminum alloy. Generally speaking, the silicon content is between 0.4% and 1.0%, and the magnesium content is between 0.4% and 0.9%, and the specific ratio is determined according to the actual application scenario and use requirements.
(2) Stainless steel material ratio:
The ratio of stainless steel is more complex, and the composition and performance of different grades of stainless steel are also different. Take 304 stainless steel as an example, it contains about 8% nickel, 18% chromium and 8% carbon and other elements. At the same time, in order to improve the corrosion resistance and high temperature strength of stainless steel, titanium, nitrogen and other elements may also be added.
(3) Engineering plastic material ratio:
The ratio scheme of engineering plastics depends on the specific application requirements and material performance requirements. Common engineering plastics include polycarbonate (PC), polyamide (PA) and polyformaldehyde (POM). For example, in polycarbonate, glass fiber, mineral or other modifiers are generally added to improve its strength, heat resistance and dimensional stability.
(4) Composite material ratio:
The proportioning scheme of composite materials depends on its performance requirements and application scenarios. In the manufacturing of energy storage power supply shell, commonly used composite materials include carbon fiber reinforced plastic (CFRP) and glass fiber reinforced plastic (GFRP). The content of carbon fiber in carbon fiber reinforced plastics is generally between 25% and 50%, while the content of glass fiber in glass fiber reinforced plastics is usually between 10% and 30%.
In short, in the matching process of outdoor energy storage power supply shell materials, it is necessary to choose the appropriate material and matching scheme according to the actual application scenario and use requirements. A reasonable material ratio can improve the performance, reliability and life of the energy storage power supply, and also reduce the cost.
