Custom New Energy Harness

As a trusted new energy wiring harness supplier, we present our custom new energy harness solution designed for electric vehicles, energy storage systems, charging stations, and related new energy equipment. This wiring harness system supports both high-voltage power transmission and low-voltage control/signal lines, offering a one-stop, fully tailored solution to meet diverse project requirements.

New Energy Wiring Harness Key Features & Benefits

High Voltage & Safety Design

Utilizes high-grade insulation materials (e.g. XLPE, TPE, fluoropolymer) to withstand elevated temperatures and voltage stress

Meets or exceeds required dielectric strength with robust insulation thickness and rigorous voltage-withstand testing

Incorporates creepage/clearance design, shielding, and grounding paths to ensure electromagnetic compatibility (EMC) and system safety

Tailored Customization

Fully custom wiring layout based on your schematics: wire lengths, branch points, connectors, wire gauges, shielding, bundle structure, color coding, labeling

Wide compatibility with mainstream connector types (e.g. Deutsch, TE, Amphenol, IP-rated, waterproof plugs)

Support for variant versions (e.g. different lengths, branch count, power ratings) with repeatability

Quality Assurance & Testing

Every harness is 100% tested with continuity, insulation resistance, and dielectric / high-voltage (hipot) tests

Optional environmental reliability tests (thermal cycling, vibration, salt spray, humidity) per customer requirements

Full traceability on wire batches, components, production logs

Regulatory & Material Compliance

Non-toxic materials for safe operation

Design for Manufacturability & Serviceability

Modular segments and service loops for easy maintenance or replacement

Clear and permanent labeling of each branch and end for installation convenience

Strain relief, protective sleeves, tubing, clamps to protect wires from abrasion and stress

Typical Applications

Main wiring harness and sub-harnesses for electric vehicles

Battery pack interconnect harnesses (BMS to modules)

High-voltage to motor / inverter / charger harnesses

Energy storage system wiring between modules, racks, converters

Charging station internal harnesses

Photovoltaic / solar power system wiring bundles

Various control, sensor, and communication wiring in new energy equipment

Because we specialize in new energy wiring harness development, we understand the challenges in durability, safety, and system integration in these environments.
