Development Trend Analysis of Chinese Automobile Wiring Harn

Automotive wiring harness is the central nervous system of automobile, the carrier of automobile energy and various signal transports. It organically connects the central control unit with automobile control unit, electrical and electronic execution unit and electrical components to form a complete automobile electrical control system.
According to the statistics of China Automobile Industry Association, in 2006, China's automobile production and sales were 7.2797 million and 7.216 million respectively. After ten years of economic growth, urbanization and improvement of living standards, the demand for automobiles by ordinary families increased substantially. In 2017, the production and sales of automobiles were 29.11 million and 29.12 million. In the past ten years, automobiles were produced and sold in China. Vehicle production and sales have more than tripled.
With the continuous increase of automobile sales, the demand for automobile wiring harness has also increased substantially, and the market capacity of automobile wiring harness has increased rapidly. In the field of traditional automotive electronics, the average value of bicycle harness products is about 2,000 yuan, while some high-end models are higher. China's automobile output in 2017 is 29.01 million vehicles. Based on the price of single-car wiring harness yuan, it is estimated that the annual demand for Chinese automobile electronic wiring harness products will exceed 57.8 billion yuan. With the continuous growth of automobile consumption, it is estimated that China's automobile wiring harness market will reach 66.1 billion yuan in 2019.
From the current development situation, there are three major trends in the automotive wiring harness industry.
—— 1——
Rapid Development of New Energy Vehicles
Will promote the transformation and upgrading of automobile wiring harness
Facing the increasingly serious global energy shortage and environmental pollution problems, countries and regions represented by the United States, Japan, the European Union and China have begun to transform, and have successively upgraded new energy vehicles into national strategies, in order to alleviate energy shortage and reduce the pressure of environmental pollution. In the industry trend of rapid development of new energy vehicles, automobile wiring harness, as an important basic automobile component, is facing an important development opportunity of design and development, technological innovation and performance breakthrough. Compared with traditional fuel vehicles, new energy vehicles have higher requirements on harness transmission capacity, mechanical strength, insulation protection and electromagnetic compatibility.
At present, new energy electric vehicles usually use up to 600V or higher driving voltage, which is much higher than 12V voltage of fuel vehicles. Wire harness is required to have stronger voltage withstanding and sealing, so as to avoid burning accidents caused by short circuit of high voltage lines after collision. In addition, the application of new energy vehicles is AC motors, which have strong electromagnetic interference. The design of new energy vehicle wiring harness must consider electromagnetic interference to ensure the reliability of wiring harness application.
In 2017, China's production and sales of new energy vehicles reached 794,000 and 777,000 respectively, ranking first in the world for three consecutive years, with a total of 1.8 million vehicles, accounting for more than 50% of the global market. The breakthrough growth of new energy vehicles has gradually transformed the domestic automobile wiring harness Market from a low-cost strategic market to a more cost-effective market with higher technology content.
The driving voltage of new energy vehicles is high, so high voltage wire harness is needed to connect the circuit units. High-voltage wiring harness is not only a key component of high-voltage electrical system of new energy vehicles, but also an important guarantee for safe and reliable operation of new energy vehicles. Automobile wiring harness will seek breakthroughs in material, production process and product characteristics to achieve high-pressure development.
Local wiring harness suppliers in our country take the lead in entering the new energy automobile supply system by virtue of their good matching relationship with independent new energy automobile factories. Some high-quality wiring harness enterprises have achieved technological breakthroughs in the field of design and development of high-voltage wiring harness. They have leading R&D strength and huge development potential.

Lightweight of Automobile Wire Harness Products
Become the Key Development Areas in the Future
Under the background of the strengthening of global environmental protection standards, automobile manufacturers are vigorously promoting lightweight production in order to improve the fuel efficiency of automobiles. Body weight reduction will optimize the fuel economy, handling stability and crash safety of automobiles, and effectively improve the quality of automobiles. Affected by this, the lightweight development of automobile wiring harness has also become a key breakthrough area.
At present, with the rapid development of automotive electronics and information technology, the extensive use of electronic equipment makes the electrical wiring in automotive more and more long and complex. The increase of the weight of automotive wiring harness also leads to the increase of vehicle cost and energy consumption. The development goal of lightweight wiring harness is becoming more and more important.
In the aspect of weight reduction of automobile wiring harness products, in addition to using a large number of thin-walled conductors to reduce the cross-section area of the conductor, the use of aluminum as raw material with lower cost and lighter quality than copper has become a hot research direction of lightweight wiring harness.
In the future, once there are mature solutions to the problems of easy oxidation, unstable electrical and mechanical properties of aluminium conductors, lightweight aluminium wire harness is expected to become the key development direction of automobile wire harness.

Domestic Wire Harness Faucet Appearance
Capital Competition in the Future Will Accelerate the Elimination of the Good and the Bad
At present, although there are many domestic automobile wiring harness manufacturers, most of them are small in scale, weak in R&D ability, backward in production equipment, low in quality and single in matching models, mainly for independent brand matching processing. With the overall strength of self-owned brand parts enterprises strengthened, some leading wire harness enterprises which establish brand influence in high-end and high-quality wire harness market began to accelerate the industrial capital distribution, integrate industrial resources, give full play to the synergistic effect of cooperators in technology, customer resources and supporting services, and accelerate the industry survival of the fittest.
In the future, with the development of automobile industry, the requirements of automobile manufacturers for automobile wiring harness products are more stringent and complex. Small-scale and weak-strength wiring harness enterprises will face more severe market environment, while high-quality wiring harness enterprises in China will further expand their market share by virtue of outstanding product quality and stable customer resources. In the future, China's wiring harness industry will face the industrial environment of eliminating the fittest and accelerating the realization of resource integration.
