New Energy Power parts Multi in one chassis distribution box assembly 3771110-KT6A1

Engineered exclusively for target new energy vehicle models, this assembly features a precision-machined chassis mounting frame tailored to the original vehicle’s undercarriage layout. Using 3D laser scanning of the factory chassis, it matches every mounting hole, bracket position, and wiring harness interface with a tolerance of ±0.08mm—ensuring no modifications to the NEV’s existing structure. The unit’s compact dimensions (optimized for chassis space constraints) avoid interference with suspension components, exhaust systems, or battery packs. Its pre-configured wiring connectors align perfectly with the vehicle’s OEM harnesses, enabling plug-and-play installation without cutting or splicing wires. This precise fit guarantees stable mechanical fixation and reliable electrical connections, reducing the risk of vibration-induced damage or power interruptions

Built to meet strict international NEV safety standards (IEC 60664, ISO 6469), this assembly incorporates a comprehensive safety architecture. The outer enclosure boasts an IP68 waterproof/dustproof rating (surpassing basic IP67 standards) and is constructed with flame-retardant aluminum alloy (UL94 V-0 rating), resisting water immersion (1m depth for 30 minutes) and preventing fire spread in extreme cases. Internally, it features dual overcurrent protection (high-speed fuses + solid-state circuit breakers) that triggers in 0.02 seconds to shield expensive components like inverters or batteries from short circuits. It also includes insulation monitoring (IMD) functionality that continuously checks for ground faults, alerting the VCU to potential hazards—critical for HV systems in NEVs. Additionally, temperature sensors embedded in the unit prevent overheating by triggering cooling system adjustments, ensuring safe operation in -40°C to 90°C environments

Crafted with NEV chassis harsh conditions in mind, the assembly uses premium materials for long-term reliability. The main enclosure is made of 6061 aluminum alloy with a hard anodized coating (10μm thickness), providing exceptional corrosion resistance (withstanding 500 hours of salt spray testing) and impact resistance (able to absorb 20J of energy without deformation). Internal busbars are constructed from high-conductivity copper (99.9% purity) with silver plating, minimizing electrical resistance (≤0.008Ω) for efficient power transmission and preventing oxidation. The assembly undergoes automated manufacturing processes: CNC machining for the enclosure ensures dimensional accuracy, while robotic welding for busbar connections guarantees consistent joint strength. Each unit also undergoes a 100% vibration test (5–2000Hz, 10g acceleration) and electrical performance verification (insulation resistance ≥100MΩ at 1000V DC), ensuring it endures years of road use without failure

Designed for hassle-free deployment and upkeep, this assembly simplifies NEV maintenance workflows. It comes with pre-assembled mounting brackets, torque-marked bolts, and a color-coded wiring diagram—allowing technicians to complete installation in 25 minutes or less (50% faster than multi-component setups) without specialized tools. The enclosure features a tool-less quick-release cover with a transparent inspection window, enabling visual checks of fuses and connectors without disassembly. For maintenance, the modular internal design allows individual components (e.g., fuses, sensors) to be replaced independently, reducing repair costs by 40% compared to integrated units. It also includes a diagnostic port compatible with standard NEV scan tools, enabling real-time fault detection and troubleshooting. Backed by a 48-month warranty against manufacturing defects, this assembly minimizes downtime and total cost of ownership for NEV fleets and owners
