SMC has excellent lightweight effect, low price, good corrosion resistance and good insulation. It is a popular lightweight alternative material for battery pack shell. SMC composite materials are used in BAIC C30, C33, GAC a3x, A51, Geely Dihao ev450, futuristic K50, GAC new energy GAC motor ge3 530, Changan second generation escape EV battery pack shell.
At present, the battery pack shell is transitioning from a pure metal box to a metal-composite hybrid box, and the combination of dissimilar materials is the main form. The biggest advantages of the composite structure formed by dissimilar materials are good fatigue resistance, corrosion resistance and lightweight, especially in terms of lightweight. The main types of connections between different materials are glued, mechanically and hybridly.
From the perspective of the materials and structures used in the battery pack box at home and abroad, in the selection of materials: if metal is selected as the box material, the manufacturing process is not a one-time molding, and subsequent welding and reinforcement steps are required, which increases the quality of the battery pack; When choosing composite materials, it is necessary to balance the manufacturing cost, stiffness and fatigue durability of the battery pack case. At present, the battery pack box is mainly based on the aluminum alloy lower box and the SMC composite upper cover, and the mixed material box structure will be the main development trend.
