According to our (Global Info Research) latest study, the global EV High Voltage Harness market size was valued at US$ 6223 million in 2025 and is forecast to a readjusted size of US$ 23110 million by 2032 with a CAGR of 20.8% during review period.
EV High Voltage Harness are specialized electrical connection components used in EV high-voltage systems. They are responsible for transmitting high-voltage electrical energy (typically 400V to 800V) between the power battery, motor, electronic control system, and charging system. Made from materials with excellent insulation, high temperature resistance, electromagnetic interference resistance, and flame retardant properties, they feature a robust shielding and protection structure to ensure the safe and stable transmission of high-voltage current. Compared to traditional low-voltage wiring harnesses, high-voltage wiring harnesses have higher requirements in terms of structural design, insulation protection, and safety monitoring, making them a key component for the safe operation of EV power systems. In 2024, global sales of EV high-voltage wiring harnesses were approximately 180.54 million units, with an average price of approximately US$24.58 per unit and an average gross profit margin of approximately 23%-25%. Upstream companies are mainly suppliers of cables, sheathing materials, connectors, etc., including Prysmian, 3M, Nitto, and TEMolex.
With the rapid development of the global new energy vehicle industry, the importance of high-voltage wiring harnesses in electric vehicles (EVs), as a core component of EV electrical systems, is increasingly prominent. High-voltage wiring harnesses not only handle the transmission of high-voltage power between battery packs, drive motors, and power electronic devices, but also directly affect the safety, reliability, and energy efficiency of the entire vehicle. Compared to traditional wiring harnesses, high-voltage harnesses have higher requirements in terms of insulation performance, high-temperature resistance, electromagnetic interference resistance, and flexible design, thus becoming an indispensable key component in new energy vehicles. With continuous technological iteration, lightweight, highly flexible, and modular high-voltage wiring harnesses have become important tools for improving the performance and range of electric vehicles, driving the steady improvement of vehicle intelligence and electrification levels.
From a market perspective, the continued growth in the global EV market has driven the rapid development of the high-voltage wiring harness market. According to industry research data, the global EV high-voltage wiring harness market will maintain steady growth over the next five years, especially in major new energy vehicle markets such as China, Europe, and North America, where demand continues to rise. New energy vehicle manufacturers are setting higher standards for high-voltage wiring harnesses, prompting suppliers to continuously innovate in material research and development, production processes, and quality control. Meanwhile, with the gradual optimization of high-voltage wiring harness costs and the improvement of production automation, the overall efficiency and profit margins of the industry chain have been further enhanced. This trend has not only driven technological upgrades for domestic and foreign companies but also provided solid support for the stable development of the new energy vehicle industry chain.
With increasing policy support and market demand, high-voltage wiring harnesses for electric vehicles will continue to be one of the core driving forces for the upgrading of the new energy vehicle industry, leading the development trend of intelligent mobility and green transportation.
