High-voltage: The popularization of 800V platforms has driven a sharp increase in demand for high-voltage wiring harnesses. The global market size is expected to reach 18 billion US dollars by 2025, with China accounting for 45%. The ultra-high voltage liquid-cooled wiring harness jointly developed by CATL and Aptiv has been adapted to the 1000V platform. The technical challenges include silicone insulating materials, three-layer shielding structure and liquid cooling technology.
Lightweight: Replacing copper wires with aluminum wires can reduce weight by 30%, and carbon fiber sheaths further lower the weight of the wiring harness. Huguang Co., Ltd. has increased the conductivity of aluminum wires to 97% of that of copper through nano-coating technology, solving the problem of aluminum oxidation.
Intelligence: L3+ autonomous driving has given rise to the demand for high-speed wiring harnesses, and in-vehicle Ethernet (10Gbps) has become mainstream. The Ideal L9 adopts an Ethernet backbone network, reducing the length of the wiring harness by 40% and lowering latency by 60%. The concept of intelligent wiring harnesses has emerged, integrating sensors to monitor parameters such as temperature, current, and vibration in real time, enabling predictive maintenance.
