Automotive wiring harnesses are generally divided into two types: main wiring harnesses and small wiring harnesses. With the development of new energy vehicles, automotive wiring harnesses can be divided into two types: low-voltage wiring harnesses and high-voltage wiring harnesses. Traditional fuel vehicles mainly use low-voltage wiring harnesses, and new energy vehicles mainly use high-voltage wiring harnesses.
The rapid development of new energy vehicles will drive the growth of demand for high-voltage wiring harnesses. According to estimates, the global market size of high-voltage wiring harnesses for new energy vehicles will reach 4.69 billion yuan in 2020, a year-on-year increase of 41.4%, accounting for about 3% of the scale of automotive wiring harnesses. In the future, driven by governments and major automakers, the sales share of new energy vehicles will continue to increase, and the market size of high-voltage wiring harnesses will continue to grow rapidly in the next few years.
At present, global automotive
Wiring Harness companies are mainly divided into four echelons. The first echelon is Yazaki and Sumitomo Electric, the second echelon includes Aptiv, Leoni and Lear, the third echelon includes Dekosmier, Kromberg & Schubert, Furukawa Electric, Yura, Kyoshin, Fujikura, and the fourth echelon includes other small wiring harness companies.
At present, the global automotive wiring harness market is mainly occupied by the first three echelons, forming a stable supporting system with major global automobile manufacturers. At the same time, due to the huge development potential of the Chinese wiring harness market, international wiring harness manufacturers mainly deploy the Chinese market through acquisitions, sole proprietorship or joint ventures with local enterprises, and provide supporting services for joint venture car manufacturers and local car manufacturers.
With the increasing localization of automotive parts procurement, some local wiring harness companies have significantly enhanced their overall strength through long-term accumulated product technology and synchronous development experience, and gradually entered the supplier supporting system of international automobile manufacturers with timely and effective services and reliable product quality.
With the increasing richness of automobile functions, the demand for automotive wiring harnesses has also increased significantly, which directly leads to a significant increase in the length and weight of automotive wiring harnesses, resulting in a significant increase in the weight of the car, and the difficulty of wiring harnesses has greatly increased. Therefore, automotive wiring harnesses must be optimized from quality to wiring to meet the booming demand. We believe that automotive wiring harnesses will mainly develop in the following aspects:
One of the development trends of automotive wiring harnesses: lightweight
As an important component of the whole vehicle, automotive wiring harnesses account for about 5% of the weight of the whole vehicle. With the development of lightweight automobiles, lightweight automotive wiring harnesses have become a key development area in the future. At present, there are three main ways to lightweight automotive wiring harnesses. One is to make the insulation layer of the wire thinner; the second is to improve the process to miniaturize the cross-section of the wiring harness; the third is to use lighter materials.
Development trend of automotive wiring harnesses 2: optimization of electronic and electrical architecture design
Lightweighting of automotive wiring harnesses can reduce the weight of the wiring harness to a certain extent, but fundamentally reducing the amount of automotive wiring harnesses is more beneficial for automotive wiring harness optimization. Therefore, the adoption of new electronic and electrical architectures is the key to promoting automotive wiring harness optimization. The new electronic and electrical architecture can simplify the line design, reduce the wiring required to support various vehicle functions, and reduce the weight, which is conducive to automated production and thus reduces costs.
Development trend of automotive wiring harnesses 3: Automation of production processes
Due to the complex structure of automotive wiring, 95% of the wiring harnesses currently need to be produced manually, with low production efficiency. It is a typical labor-intensive industry, and labor costs have become one of the main factors restricting enterprises from expanding production capacity and achieving scale effects. At present, most automotive wiring harness manufacturers are still in the stage of automated production that relies on local advanced equipment to complete some processing links, and intelligent manufacturing has not yet been popularized.
In the future, as automotive wiring harnesses are gradually integrated and production technology continues to advance, intelligent manufacturing is expected to be realized throughout the entire process of automotive
Wiring Harness Design, production, warehousing, logistics, management and service.
Development trend of automotive wiring harnesses 4: Using wireless communication to reduce the amount of wiring harnesses
If wireless communication is used in the process of automotive communication, the amount of automotive wiring harnesses can also be reduced accordingly.
