Aluminum Case For EV Lithium Battery Pack
Products Description
The Aluminum Case for EV Lithium Battery Pack is a core component of power battery packs designed specifically for new energy vehicles (passenger cars/commercial vehicles), energy storage power stations, and mobile charging equipment. Its core architecture utilizes an integrated structure of "aerospace-grade aluminum profile integrated molding + multi-cavity heat dissipation structure + high-strength sealing protection" to achieve physical support, efficient heat dissipation, waterproofing and dustproofing, collision protection, and safety isolation for the lithium battery cells. Unlike the "single wrapping" positioning of general-purpose metal shells, its core value lies in solving four major pain points in EV scenarios: "lightweight and strength balance, battery thermal runaway prevention, vibration resistance in complex road conditions, and sealing in extreme environments." It combines the lightweight characteristics of aluminum alloy with the safety redundancy required for lto lithium cells Aluminum shells, making it a core component for achieving improved range, enhanced safety, and extended lifespan in new energy vehicles.
Main Functions
Physical Safety Barrier
Resists external impacts, vibrations, compression, and punctures, protecting the internal structure of the Aluminum shell for lithium polymer battery cell.
Chemical Sealing Container
Prevents electrolyte leakage, isolates external moisture and air, and maintains a stable chemical environment inside the Aluminum shell for lithium ion prismatic cell.
Thermal Management Core
Serves as a critical path for heat conduction within the battery cell, working in conjunction with the cooling system to achieve precise control of the prismatic LFP cells Aluminum shell's operating temperature.
Electrical Insulation Support
The surface-treated cell lithium battery Aluminum shell possesses excellent insulation properties, preventing short circuits between the battery cell's positive and negative terminals and the external structure.
Manufacturing Advantages: A Perfect Blend of Precision and Sustainability
Intelligent Precision Manufacturing Process
We employ advanced intelligent manufacturing systems to achieve end-to-end digital management from design to production. AI-assisted design ensures all key factors are considered during product development, while intelligent production lines ensure every product meets the highest standards. An intelligent quality control system monitors key parameters in real time during manufacturing, ensuring consistent lithium prismatic battery Aluminum shell performance and reliability.
High-Precision CNC Machining Technology
The square aluminum shells are manufactured using high-precision CNC machining technology, ensuring each dimension is accurate to the micron level. Precision milling and stamping processes ensure a smooth, burr-free surface, avoiding surface defects common in traditional machining. This precision machining allows the lithium dry cell battery Aluminum shells to maintain structural integrity over long-term use.
Environmentally Friendly and Sustainable Manufacturing
Our manufacturing processes strictly adhere to environmental standards, employing low-energy, low-emission technologies. All waste is sorted and processed to minimize environmental impact. In material selection, we prioritize the use of recycled aluminum alloys to reduce resource consumption and support the circular economy.
Technical Features: Focusing on the Core Needs of EV Lithium Battery Packs
Lightweight Structure Optimization Technology
Utilizing a "multi-cavity hollow profile + localized reinforcing ribs" design, while maintaining a tensile strength ≥260MPa, Lithium Ion Cell Aluminum Shell reduces weight by 35% compared to traditional structures, achieving an optimal balance between strength and weight, directly improving vehicle range.
01
Multi-cavity Heat Dissipation Technology
The cavity separation design allows for rapid heat conduction from the cells through the cavity walls. Combined with reserved water/air cooling channels, it forms an efficient heat conduction path of "cell-cavity wall-heat dissipation system," with a cell temperature difference ≤5℃, suppressing thermal runaway.
02
High-Strength Welding and Sealing Technology
Fiber laser welding technology achieves weld seams with equal strength to the base material. Combined with fluororubber sealing rings, the sealing rating reaches IP67/IP68, capable of withstanding harsh environments such as water immersion, heavy rain, and dust, ensuring the Aluminum shell for lithium ion phosphate cell's internal dryness and cleanliness.
03
Vehicle-level collision protection technology
The li on cell Aluminum shell structure is optimized through finite element simulation, employing a partitioned design of "energy-absorbing buffer zone + rigid load-bearing zone." During a collision, it can absorb over 80% of the impact energy, preventing cell deformation and meeting vehicle collision safety standards.
04
Modular adaptation technology
Compatible with square ternary lithium and lithium iron phosphate cells, EV Battery Pouch Cell Aluminum Case reserves standardized cell mounting positions, wiring harness channels, and BMS installation interfaces, supporting flexible capacity expansion from 20kWh to 200kWh to adapt to different vehicle model requirements.
