Low-voltage wiring harnesses for electric vehicles (EVs) are critical connection systems for low-voltage power and signal transmission in EVs and hybrid vehicles. They typically operate at voltages below 60V and are primarily responsible for the electrical connections between functional modules such as body control, lighting, instrumentation, air conditioning, infotainment, safety, and communication. Composed of wires, connectors, sheaths, and fasteners, they achieve vehicle signal transmission and power distribution through rational wiring design. Compared to traditional gasoline vehicles, EV low-voltage wiring harnesses have higher requirements in terms of system complexity, communication bandwidth, and electromagnetic interference resistance, forming the fundamental electrical network supporting the intelligent and electrified operation of the entire vehicle. In 2024, global sales of EV low-voltage wiring harnesses were approximately 1,265.64 million units, with an average price of approximately US$7.16 per unit and an average gross profit margin of approximately 18%-20%. Upstream companies are mainly suppliers of cables, sheathing materials, connectors, etc., including Prysmian, 3M, Nitto, and TEMolex.

With the rapid development of the electric vehicle industry, the complexity and intelligence level of vehicle electrical systems are constantly increasing. Low-voltage wiring harnesses, as core components connecting various electronic control units (ECUs) and functional modules throughout the vehicle, are playing an increasingly crucial role. Electric vehicle low-voltage wiring harnesses are primarily responsible for transmitting low-voltage electrical energy and signals for body control, lighting, air conditioning, instrumentation, airbags, communication, and infotainment systems, forming the fundamental "nervous system" of the vehicle's intelligent network. Compared to traditional gasoline vehicles, electric vehicles employ a more complex electronic and electrical architecture, adding new functions such as high-voltage systems, intelligent driving, and vehicle networking, posing greater technical challenges to low-voltage wiring harnesses in terms of wiring density, signal transmission speed, and anti-interference performance.

From a technological evolution perspective, electric vehicle low-voltage wiring harnesses are undergoing a technological transformation towards "lightweighting, integration, intelligence, and high reliability." To meet the demands for vehicle lightweighting, industry companies are actively adopting aluminum conductors, composite material wires, and thin-walled insulation materials to reduce weight and cost while ensuring safety. Meanwhile, wiring harness layouts are transitioning towards a centralized E/E architecture, achieving modular and zoned wiring through Zone Controllers, significantly reducing traditional, complex point-to-point connections. The introduction of intelligent technologies has transformed low-voltage wiring harnesses from simple power and signal carriers into intelligent functions such as real-time monitoring, current detection, and temperature sensing, providing data support for the safe operation of the entire vehicle's electrical system. Furthermore, with the application of Ethernet communication in electric vehicles, the transmission capacity and shielding performance of low-voltage wiring harnesses are continuously improving, providing higher bandwidth electrical protection for autonomous driving and intelligent cockpits.

From an industry and market perspective, low-voltage wiring harnesses for electric vehicles are becoming one of the fastest-growing segments in automotive electrical systems. As the penetration rate of electric vehicles continues to rise, the usage and complexity of wiring harnesses are significantly increasing, leading to rapid market expansion. Industry research predicts that the global low-voltage wiring harness market for electric vehicles will maintain steady growth over the next five years; China, as a core market for electric vehicle production and consumption, is becoming the main battleground for the global wiring harness industry upgrade. Internationally renowned wiring harness companies such as Aptiv, Sumitomo Electric Industries, and Yazaki are increasing their investment in the electric vehicle wiring harness field, while domestic companies are actively making breakthroughs in key areas such as materials technology, automated processing, and intelligent testing, accelerating their transformation from OEM manufacturing to independent R&D and system integration. Innovative solutions such as highly flexible wiring harnesses, low-noise communication lines, and optimized shielding designs are constantly emerging, driving the entire industry towards high performance and high added value.

Overall, low-voltage wiring harnesses for electric vehicles are not only the "lifeline" of the vehicle's electrical system but also a key support for the integration of intelligence and electrification. Their technological level directly affects the safety, reliability, and intelligence of the entire vehicle. In the future, with the widespread application of centralized architecture, high-speed communication, and intelligent diagnostics, low-voltage wiring harnesses for electric vehicles will move from "passive transmission" to "active management," realizing the digital and intelligent upgrade of the electrical system. Facing the rapid changes of the electrification era, technological innovation and industrial collaboration in the low-voltage wiring harness industry will become an important engine for promoting the high-quality development of the automotive industry, contributing to the future blueprint of green travel and intelligent transportation.
