Against the backdrop of global advocacy of conservation and environmental protection, new energy vehicles have become an inevitable trend in the development of automobiles around the world. According to the Blue Book of China's Auto Industry released by PricewaterhouseCoopers for the first time on December 8, sales of new energy vehicles in China are far ahead of other markets in the world. With the government's vigorous support for new energy vehicles, the era of new energy vehicles in China has arrived. In 2015, the global sales of new energy vehicles reached 500,000 units, of which 330,000 units were sold in China, three times that of the previous year, far ahead of other markets in the world. Accelerated development, Internet giants and other emerging players are actively pouring into the market, bringing pressure and impact to traditional automakers and dealers. There is no doubt that new energy and intelligent networked vehicles have become the mainstream of the automotive industry's upgrading, and the demand for their applicable wiring harnesses will also increase significantly.

Automotive wiring harness - the nervous system of the car

The automobile wiring harness is the main body of the automobile circuit network and a connecting component belonging to the automobile electrical system. The operating conditions and parameters of the car are intuitively reflected on the on-board computer through the wiring harness, so it has always been called the "blood vessel" of the car. The electronic technology content of automobile wiring harness has gradually become an important indicator for evaluating automobile performance. An automotive wiring harness is usually the final assembly completed on a vehicle model and is an assembly of cables or wires used to carry signals or power in the car. The wires are assembled together with the help of different elements such as cable ties, electrical tape, conduit or a combination of these to form a complete wiring assembly. Automotive wiring harnesses protect wires from vibration better than individual wires.

With the wide application of integrated circuits and various MCUs in automobiles, the number of ECUs (Electronic Control Units, Electronic Control Units) in automobiles is increasing, which makes the automobile wiring system large and complex, and requires more data transmission. It is constantly improving, so the design of automotive wiring harnesses is also becoming more complicated. Various companies have developed design software and CAD tools to design automotive wiring harnesses. Analysts at Technavio, the world's authoritative market research organization, predict that from 2016 to 2019, the automotive wiring harness market in the Asia-Pacific region will grow at a compound annual growth rate of 9.51%. It is estimated that the global automotive wiring harness market will reach USD 59.2 billion in 2019.

The hot new energy vehicle market brings new opportunities for the development of the wiring harness industry

Compared with traditional vehicles, electronic systems of new energy vehicles have more stringent requirements in terms of physical and performance. Taking the automotive connector and wiring harness subdivision industry in the automotive electronics industry as an example, the automotive connector and wiring harness are key components for signal transmission in the automotive electronic system. It integrates the vehicle central control unit, automotive control unit, electrical and electronic execution unit and electric device are organically connected. Generally speaking, the amount of traditional automotive wiring harnesses and connectors is about 200 and 350 respectively, and the value of single-vehicle connectors and wiring harnesses is about 3,000-5,000 yuan. However, with the development of automotive electronics, intelligence, networking, and new energy, the value of bicycle connectors and wiring harnesses will increase to 20,000 yuan, showing that the automotive electronic connectors and wiring harness industry has a broader development space.

In addition, the electronic equipment of new energy vehicles is more complex and requires more comprehensive and powerful wiring harness functions. The requirements for new energy vehicle wiring harnesses and traditional automotive wiring harnesses can be described as "very different". One is that the wiring harness of new energy vehicles works in a high-current and high-voltage environment, which can easily cause the wiring harness to heat up. Therefore, the wiring harness needs to be designed thicker to facilitate heat dissipation. The second is because the motor of new energy vehicles is generally installed in the front of the car, and the battery is generally installed in the rear of the car. For the safety of the car, the wiring harness cannot be placed in the car like a traditional car, but is required to be wired outside the car, so Its mechanical protection is very important, such as moisture-proof, moisture-proof and so on. The third is that because the motors of new energy vehicles use alternating current, the interference is very serious, so the wiring harness is required to shield the interference and have better sealing.

The new requirements for new energy vehicle wiring harnesses will inevitably lead to a technological revolution in the wiring harness processing industry. The wire harness production itself is a labor-intensive industry. With the changes in the labor market today, the cost of labor has become higher and higher, which puts pressure on the production enterprises. But this problem has been alleviated under the use of automation equipment.
