Fire-resistant new energy battery casings deliver thermal protection for electric vehicle and energy storage battery systems. Produced in an IATF 16949 certified facility with specialized high-temperature aluminum alloys as the outer shell, each housing achieves UL94 V-0 flame retardant performance. Our engineering team, with 22+ years of experience in automotive component design, develops casings that contain thermal runaway events, safeguard adjacent components, and support passenger safety for EV manufacturers worldwide.
The casings meet international and domestic fire safety standards, including UL94 V-0 rating from the vertical burning test and GB 8624 Class A rating for building material fire performance. When the ignition source is removed, the material self-extinguishes within 10 seconds, with no flaming drips produced during combustion. These verified ratings help business buyers meet regional fire safety requirements for new energy equipment deployment.
The casing maintains structural integrity across a long-term operating temperature range from -40℃ to 150℃, adapting to diverse climate conditions and working scenarios. During battery thermal runaway events, it can withstand short-term exposure to temperatures up to 800℃, restricting fire spread and reducing damage to internal battery modules and surrounding system components.
The product adopts a composite structure design: the outer shell is fabricated from specialized high-temperature aluminum alloy, while the inner protective lining uses glass fiber-reinforced modified polypropylene (PP) or flame-retardant nylon. This combined structure delivers impact resistance of ≥15kJ/m², along with corrosion resistance against battery electrolytes and environmental humidity, supporting stable performance in complex working conditions.
The casing is designed with a precision-machined sealing groove that achieves IP67 and IP68 waterproof and dustproof ratings, preventing dust and liquid intrusion into internal battery components. Reinforced edge structures are added to absorb external impact force, reducing the risk of physical damage to battery modules during transportation, installation and daily operation.

Customized dimensions are available to fit different new energy product designs. For electric vehicle battery packs, the casing length can be adjusted from 500mm to 2000mm based on specific project requirements. The solution also adapts to household energy storage boxes, portable power stations and other new energy devices of varying sizes. Reserved interfaces for wiring and heat dissipation modules are supported to match system integration needs of industrial clients.
The casings are compatible with multiple battery chemistries, including lithium-ion batteries, lithium iron phosphate (LFP) batteries and solid-state batteries. Key application fields cover battery packs for electric vehicles (EV) and hybrid electric vehicles (HEV), grid-scale and household energy storage systems, portable new energy devices such as solar generators, and industrial new energy equipment such as forklift battery enclosures.
All units undergo 100% fire performance testing before delivery to verify consistent flame retardant performance across every batch. Production processes follow IATF 16949 quality management system requirements to stabilize product performance and dimensional accuracy. The products also comply with RoHS and REACH environmental regulations, supporting commercial procurement teams in meeting regional environmental compliance requirements for imported new energy equipment.
