EV Battery High Voltage Wire Harness

Our engineering team can design optimized harness layouts based on the battery module architecture, power requirements, and safety standards, ensuring proper conductor sizing, shielding, insulation, and protection levels for diverse operating environments. During manufacturing, we strictly control bend radius, electrical performance, high-temperature resistance, and vibration durability, guaranteeing long-term reliability and safety throughout the vehicle’s lifecycle.

For connector selection, we support mainstream high-voltage connectors from TE Connectivity and Amphenol, including TE HVP 800, HVP 1100, HV 2100, HC‑STAK, HVCSJI, and Amphenol ePower and HVSL series. Our solutions cover a wide range of current ratings (from tens to several hundred amps) and voltage levels (400 V–1500 V), and we can also accommodate other brands or custom connector types as required, ensuring seamless integration with the vehicle’s electrical system.
