Lightweight Technology of Battery Pack Shell

-
New energy vehicles can effectively improve their cruising range by reducing the quality of the battery system without changing the total energy of the battery system, and reducing the mass of electric vehicles by 10% can increase the driving range by 5.5%. The weight of the battery system accounts for a large proportion of the total weight of new energy vehicles. Compared with traditional fuel vehicles, the core three-electric system (battery, motor, electronic control) and intelligent equipment of electric vehicles.
hydraulic press for SMC composite battery pack shell
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.

Hydraulic Press Machine Speed Slow How To Solve

-
图片
  If your  hydraulic press machine  speed gets slowly,following are methods to solve it. 1. Air in the hydraulic cylinder When the hydraulic press machine pressing speed gets slowly, we should first consider that air in the hydraulic cylinder, interrupt the corresponding exhaust operation through the exhaust equipment of the machine, and check whether there is air in the movement direction of the piston rod. If so, it may be If the sealing ring is defective, the sealing ring should be changed in time. 2.  Check whether the hydraulic pump is operating normally When the hydraulic press machine moves slowly and the hydraulic pump runs irregularly, and sometimes it may be blocked or slightly seized, it means that there is a problem with the hydraulic pump and the hydraulic pump should be repaired or changed in time. 3. Check the operation of the piston When the hydraulic cylinder of a hydraulic press machine with a buffer device is intermittently started in reverse, the piston will be temp

Hydraulic press offers several benefits when it comes to manufacturing components for AI servers forming: AI server forming ○ Precision and Consistency Hydraulic press allows for precise and consistent shaping of metal components used in AI servers. This is essential for ensuring that the parts fit together correctly and function optimally within the server system. ○ Complex Shapes Hydraulic press enables the creation of complex and intricate metal parts that may be required in the construction of AI servers. This is particularly important as servers often contain components with non-standard shapes to accommodate various functionalities and space constraints. ○ Material Strength The process of hydraulic press can enhance the strength and durability of metal components used in AI servers. This is crucial for ensuring the reliability and longevity of the server hardware, especially in high-demand computing environments.
