Product Introduction
Aluminum Case for EV Electric Bus LiFePO4 Battery pack is a metal structural component specifically designed for prismatic lithium-ion batteries and battery modules. Its main applications include:
Cell encapsulation
Battery mechanical protection
Heat conduction and dissipation
Battery system structural support
Dust and moisture protection
Battery PACK integration and installation
Compared to traditional steel structural components, aluminum alloy battery housings significantly reduce overall weight while maintaining good structural rigidity, thus becoming one of the mainstream solutions in the new energy vehicle and energy storage industries.
Technical Features: Defensive Engineering for Thermal Runaway and IP68 Protection
| Temperature Runaway Directional Pressure Relief Topology | The lithium power cell Aluminum shell design incorporates pre-defined weak points and flow channels. When thermal runaway occurs in the battery cell, generating high-pressure gas, the shell will undergo directional explosion at a pre-set pressure relief valve location or a specific micro-area, directing the high-temperature gas flow to a safe area under the bus chassis, preventing lateral flame intrusion into the passenger compartment, thus achieving "active passive safety." |
| Multi-Media Isolation Sealing Technology | Addressing the wading depth requirements of buses, the Aluminum shell for lithium polymer battery cell flange surface employs a high-precision milling and sealing groove composite design, combined with laser-welded cover plates, achieving IP68 or even IP69K protection levels for long-term water pressure immersion, eliminating cross-contamination between condensate and electrolyte vapor. |
| EMI Electromagnetic Shielding Continuity | The inherent low impedance characteristics of aluminum alloy make the prismatic LFP cells Aluminum shell a natural Faraday cage. Combined with an equipotential bonding design, it effectively shields the high-voltage electric drive system from electromagnetic interference to the BMS (Battery Management System), ensuring zero error in signal acquisition. |
Application Advantages – From Electric Buses to Mass Validation of Energy Storage Systems
Pure Electric Buses and Coaches
Equipped with 100Ah~300Ah lithium iron phosphate cells, passing GB/T 31485-2015 vibration and extrusion tests. The 3003-H14 lithium prismatic battery Aluminum shell has not shown any corrosion or leakage cases in eight years of actual operation.
Hybrid Commercial Vehicles
Frequent power fluctuations lead to drastic temperature changes in the cells. The fatigue resistance of the 5052 casing effectively suppresses weld cracking caused by thermal cycling.
Grid Energy Storage Systems
Cost-sensitive and requiring long-term maintenance-free operation. The 1060 pure aluminum casing with passivation treatment provides the lowest cost solution under normal temperature charge and discharge conditions.
Heavy-Duty Truck Battery Swapping Packs
The high-strength 6061-T6 casing resists the impact of mechanical alignment during battery swapping and meets IP67 immersion requirements.
