New Energy Car Wiring Harness
High-Performance Power & Control Harness for Electric Vehicles
We specialize in delivering a new energy car wiring harness solution engineered for modern electric vehicles, hybrid systems, and battery-powered platforms. Our new energy car wiring harness for sale integrates high-voltage power distribution, low-voltage control circuits, sensor and communication lines, all in a robust, reliable package. In particular, our new energy vehicle power battery wiring harness is designed to interconnect battery packs, BMS modules, and vehicle loads with optimal safety and efficiency.
As a manufacturer with strong customization capabilities, we support tailored harness designs to suit your vehicle architecture, battery configurations, and system integration needs.
Key Features & Advantages
1. Optimized for High-Voltage Battery Systems
Insulation materials such as cross-linked polyethylene (XLPE), fluoropolymer, or high-temperature thermoplastics ensure excellent dielectric strength, thermal stability, and resistance to ozone and corona.
Proper creepage and clearance design, shielding or semi-shielding layers, and grounding paths help suppress electromagnetic interference (EMI) and enhance system robustness.
Pure copper or tinned-copper conductors with low resistance reduce energy loss, boosting overall efficiency in the vehicle’s powertrain.
2. Full Customization & Modular Design
We can configure every aspect of the harness: wire gauge, color coding, branch points, connector types, shielding, length tolerances, labeling, and bundling.
Our harnesses are modular and service-friendly (easy disconnection, maintenance, replacement), suited for system upgrades or repair.
Compatibility with standard automotive connector systems ensures integration flexibility.
3. Stringent Testing & Quality Assurance
100% electrical testing on each harness (continuity, insulation resistance, hipot/dielectric test) before delivery.
Optional environmental and reliability tests: thermal cycling, vibration, salt spray, humidity, mechanical fatigue, etc.
Traceability from raw materials (wire batches, insulation batches, connector lots) through production logs, inspections, and final delivery.
4. Material Certifications & Compliance
All materials can meet RoHS, REACH, and applicable automotive industry standards.
5. Durability & Harsh-Environment Performance
Resistant to chemicals, oil, moisture, UV, and mechanical abrasion
Strain reliefs, protective sleeves, grommets, and clamp points are included to protect against bending, vibration, and chafing.
Typical Applications
Main and sub harnesses in electric vehicles
Battery pack-to-vehicle wiring (BMS, HV bus, distribution)
