‌Customized High-Voltage Harness Solutions

High-voltage harness solutions are critical for ensuring the safety, efficiency, and reliability of ‌new energy vehicles‌ (NEVs), including electric trucks, buses, and commercial fleets. Designed to withstand extreme conditions—such as high temperatures, vibrations, and electromagnetic interference—these harnesses connect essential components like battery packs, motors, and auxiliary systems (e.g., PTC heaters and AC compressors) to optimize vehicle performance and passenger comfort. 

Application Scenarios: Precision Meets Practicality‌

In ‌new energy vehicles‌, high-voltage accessory harnesses are engineered for diverse commercial applications:

• ‌Climate Control Systems‌: Connect PTC heaters and AC compressors to ensure cabin temperature stability, which is vital for driver comfort in extreme weather.
• ‌Auxiliary Power Management‌: Link DC/DC converters and battery thermal management systems to maintain energy efficiency in long-haul electric trucks.
• ‌Charging Infrastructure Integration‌: Enable fast-charging compatibility for depot-based electric buses, reducing downtime.

‌

Core Features: Built for Reliability‌

To meet the rigorous demands of ‌new energy vehicles‌, these harness assemblies prioritize:

• ‌High-Temperature Resistance‌: Silicone-insulated cables withstand 150°C+ environments near powertrains and battery packs.
• ‌Vibration Resilience‌: Reinforced connectors (e.g., AMPSEAL or Deutsch HD series) prevent loosening in rough terrain.
• ‌EMI Shielding‌: Triple-layer braided shielding protects low-voltage control signals from high-current interference.
• ‌Modular Design‌: Plug-and-play architecture simplifies maintenance for fleet operators.

Certifications & Standards: Safety First‌

To align with global NEV regulations, premium harness solutions adhere to:

• ‌ISO 19642‌: Automotive cable standards for mechanical strength and electrical stability.
• ‌RoHS/REACH‌: Hazardous substance-free materials ensure eco-compliance.
• ‌LV214‌: Validates high-voltage connection durability under thermal cycling stress.
