1. Global high-voltage harness market expands rapidly, exceeding 150 billion yuan in 2025 Driven by booming new energy vehicles, energy storage systems and ultra-fast charging facilities, demand for high-voltage harnesses (above 300V) rises exponentially. In new energy vehicles, the value of high-voltage harnesses per car ranges from 2000 to 5000 yuan, 3 to 5 times that of traditional fuel vehicles. The global market size is projected to hit 156 billion yuan in 2025, with an annual compound growth rate over 25%. Enterprise developments: Aptiv invests 1 billion US dollars to expand high-voltage harness factories in Asia, mainly supplying BYD, NIO and other automakers. Leoni launches new liquid-cooled high-voltage harnesses compatible with 1000V/500A ultra-fast charging systems.
