Product Introduction
Unlike typical small consumer electronics casings, the Aluminum Case for Powerwall Lithium battery Pack features significant system-level characteristics. Its design aims to address stress issues caused by cell expansion and achieve high-density energy integration within a limited space.
Modular Stacking Design: The product features a precise stacking interface structure. Whether wall-mounted or floor-standing, multi-unit rack-mounted, the top and bottom of the aluminum casing are designed with interlocking positioning slots and load-bearing bosses. This design allows multiple battery modules to be stacked stably like building blocks, transferring the weight of the upper layers directly to the ground through the casing structure, preventing compression of the internal cells.
Ultimate Space Utilization with Square Geometry: The square aluminum casing offers the highest volume utilization rate for the arrangement characteristics of lithium iron phosphate (LFP) or ternary lithium battery cells. The internal space is divided into independent cell compartments and high-voltage electrical compartments, achieving physical isolation and preventing electrolyte leakage from corroding the low-voltage control circuitry.
Manufacturing Advantages: CNC Precision Machining and Control of Large-Size Components
Large Precision CNC Machining Center
For Aluminum shell for Prismatic and cylindrical battery cases exceeding 1 meter or even 2 meters in length, we are equipped with a large-stroke five-axis machining center. This ensures precise control over the flatness and position of mounting holes, sealing grooves, and heat dissipation surfaces. In particular, the machining precision of the sealing grooves directly determines the achievement of IP65/IP67 waterproof ratings.
Welding and Stress-Relief Annealing
For structures requiring welding and splicing, we use imported automated welding robots (TIG/MIG) to ensure aesthetically pleasing welds free of porosity. Post-weld stress-relief annealing eliminates residual welding stress and prevents dimensional deformation during subsequent processing or use.
High-Precision Bending Process
The bending angle of the side panels is crucial. We utilize CNC bending machines in conjunction with high-precision molds to ensure consistent bending radius angles and precise springback control, guaranteeing a seamless fit between the side panels and the frame for Lithium Ion Cell Aluminum Shell.
Comprehensive Cleaning and Packaging
Energy storage batteries require extremely high cleanliness. After production, the Aluminum shell for single cell lithium ion battery undergoes multi-stage pure water cleaning and drying to thoroughly remove cutting fluid, aluminum shavings, and oil. Packaging uses anti-static and scratch-resistant materials to ensure the product delivered to the customer is spotless.
