New Energy Power parts
This power battery housing assembly (Part No.: 2120310-TZ3R0) is constructed with a multi-layer reinforced structure—the outer shell uses high-strength aluminum alloy (6061-T6) with a thickness of 3-5mm, and the inner layer is lined with 2mm thick flame-retardant PP plastic. It achieves a compressive strength of ≥500 MPa and impact resistance of ≥150 kJ/m², effectively withstanding external collisions, extrusion, or falling debris during vehicle operation. The integrated edge reinforcement ribs (height: 15mm, spacing: 50mm) further enhance structural rigidity, preventing deformation that could damage internal battery cells

PRODUCT DESCRIPTION
NEV-Specific Fit & Modular Compatibility
Exclusively engineered for new energy vehicles (BEVs/PHEVs), the housing strictly follows the dimensional specifications of mainstream power battery packs (length: 1800-2200mm, width: 1200-1400mm, height: 150-200mm—adjustable to vehicle models). It features pre-drilled mounting holes (M8 threads, 16-20 positions) that align with NEV chassis brackets, enabling direct modular installation without drilling or welding. The top cover uses a quick-release locking mechanism (12-16 stainless steel latches) compatible with automated assembly lines, and the internal slot design matches standard battery cell modules (e.g., prismatic, cylindrical), ensuring seamless integration with NEV battery systems
Efficient Thermal Management Design
The housing integrates a built-in liquid cooling/heating channel (made of 304 stainless steel, inner diameter: 8mm) arranged in a serpentine pattern at the bottom. It connects to the NEV’s thermal management system, enabling precise temperature control of battery cells (maintaining 15-35°C). The channel’s thermal conductivity is ≥45 W/(m·K), ensuring rapid heat transfer—reducing battery temperature by 8-12°C during fast charging and preventing overheating. Additionally, the housing’s inner wall is coated with a thermal insulation layer (ceramic fiber, thickness: 3mm) to isolate external high/low temperatures (-40°C to 85°C operating range), avoiding battery performance degradation
IP68 Waterproof & Multi-Layer Safety Protection
The assembly meets IP68 waterproof and dustproof standards—all seams (top cover/outer shell, channel interfaces) are sealed with high-temperature-resistant silicone gaskets (compression rate: 35±5%), and the wire entry ports use waterproof connectors (IP6K9K rated). It withstands 1.5m deep water immersion for 30 minutes without leakage, preventing short circuits caused by water ingress. Moreover, the housing is equipped with a pressure relief valve (trigger pressure: 0.15 MPa) to release gas in case of battery thermal runaway, and the outer shell’s surface is treated with an anti-corrosion coating (electrophoretic painting, thickness: 8μm) that resists road salt, acid, and alkali, ensuring a service life of ≥8 years
TECHNICAL SUPPORT
1. Accessories selection consultation
- Provide ** intelligent selection tools ** (such as parts matching query system), input the vehicle model VIN code or engine model to match the corresponding parts number, reducing the selection error rate.
The technical team is available online 7×12 hours to answer technical questions about accessories (such as material compatibility and installation processes).
2. Customized development support
We offer specialized R&D services for special market demands (such as heat dissipation accessories for high-temperature regions in the Middle East and dedicated suspension components for road conditions in Africa), and complete sample delivery within six weeks.
3. Training and Technical materials
Provide remote/on-site training for the customer's after-sales team (such as diagnosis of electrical control accessories and DPF regeneration operation), along with multilingual versions of the "Accessories Installation Manual" and "Troubleshooting Guide".
4. Quality Traceability and Improvement
Through the QR code traceability system (one product, one code), track the production batch of accessories and the source of raw materials, respond quickly to quality complaints and initiate improvement processes.
AFTER-SALES AND LOGISTICS SUPPORT
After-sales service
Quality Assurance Policy
-The warranty period for original factory parts is 12 months (counting from the date of signature for receipt), covering material defects, process issues, and man-made damage.
- Provide "Localized Express repair Service" : Cooperate with third-party repair networks in markets such as Southeast Asia and the Middle East, and deliver emergency parts to designated repair points within 4 hours.
Return and Exchange Process
-The customer is required to submit the test report (such as a third-party appraisal) within the warranty period. After confirmation by Dongfeng, a reissue or refund will be arranged within 5 working days.
Logistics support
Warehouse Layout
-Five major regional accessory centers have been established globally (Southeast Asia, the Middle East, Africa, South America, and Europe) to achieve "next-day delivery" for mainstream accessories (covering customers within the regions).
Emergency Logistics Plan
-Emergency parts can be directly delivered within 48 hours via the "Dongfeng Exclusive Aviation Special Line" (such as engine ECU, brake valves and other key components).
Packaging Optimization
-Use shockproof and moisture-proof packaging (such as honeycomb cartons + pearl cotton), and reinforce fragile parts (such as glass, sensors), keeping the damage rate within 0.5%.
