What are the "low cost and high efficiency" development strategies for automotive wiring harness industries?

According to the Analysis Report of China automotive wiring harness Industry Market Demand and Investment Planning by Prospective Industry Research Institute, the wiring harness in the automobile is an important part of the electrical system, which mainly plays the role of energy transmission and signal transmission. Common specifications of wiring harness wires for traditional diesel locomotives include wires with nominal cross-sectional areas of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0, etc. , each with an allowable load current value, is used for wires of electrical equipment with different powers.

In new energy vehicles, especially pure electric vehicles, besides the 12V circuit system, there is also a circuit system with a voltage exceeding 300V, which is mainly used for the power drive system. In this system, a high-voltage harness is needed to connect the units in each circuit. High-voltage wiring harness is the key component of the high-voltage electrical system of new energy vehicles, and it is an important guarantee for the safe and reliable operation of new energy vehicles.

Traditional cars need an average of 65 sets of wire harnesses, with a total value of about 4800 ~ 5500 yuan. On this basis, in 20 12, the global automobile sales exceeded 60 million, so the market capacity of automotive wiring harness was about 48 billion dollars. In new energy vehicles, the cost of high-voltage wiring harness will increase by 30-50% compared with ordinary automotive wiring harness due to special treatment in terms of bearing capacity, mechanical strength, insulation protection and electromagnetic compatibility, so the cost of new energy automotive wiring harness will increase by 25-40% compared with traditional vehicles. For every 6,543,800 new energy vehicles sold in China, the market capacity of high-voltage wire harness will increase by 2 billion yuan.
