Low-voltage Wiring Industry

Scheme Background

Industry Pain Point

Low-voltage platform wiring harnesses face four major issues in process, EMC, durability and supply chain, bringing hidden safety and after-sales risks.

Transmission Process

High voltage & large current cause severe heat generation; traditional crimping suffers high rates of cold solder joints and detachment.

EM Interference

Severe electromagnetic interference on 800V platforms leads to easy shielding failure.

Working Condition Durability

Harness reliability degrades drastically under temperature cycling and vehicle vibration.

Supply Chain Matching

Inconsistent manufacturing standards across multiple suppliers result in poor compatibility and prominent hidden risks.

For new energy passenger and commercial vehicles equipped with 400V/800V high-voltage platforms and under high-power fast-charging operating conditions, we rely on our core capabilities in R&D and manufacturing of high-voltage wiring harnesses as well as precision ultrasonic welding to deliver integrated high-voltage connection solutions for complete vehicles. These solutions address core technical challenges of automotive-grade high-voltage connections and ensure safe and stable operation of vehicle-wide high-voltage systems.

Solution

Core Idea
