Wiring harness is the carrier of all automotive electrical and electronic systems, which is equivalent to the nerve of the vehicle. Automotive wiring harnesses are mainly divided into high-voltage wiring harnesses for the power part of new energy vehicles and low-voltage wiring harnesses for other parts.
The performance requirements of hV wire harness are different from those of traditional low-voltage wire harness, and the industry pattern of hV wire harness is also different from that of traditional wire harness.
The load on the high voltage wire harness can be as high as 600V, and the performance has the characteristics of high insulation requirements, high temperature resistance and flame resistance.
At present, in the domestic field of high voltage wire harness, Tyco, Ambofu and other traditional foreign giants still have advantages, while Kunshan Huguang and other private enterprises develop rapidly.
In the future, with the optimization of automotive electronic architecture, automotive wiring harness may be greatly simplified, and the low-voltage wiring harness industry is likely to shrink significantly.
For example, Based on the unique automotive electronics architecture and domain division, Tesla reduced the length of the Model 3 wiring harness from 3km of Model S to 1.5km.
According to the disassembly results of overseas research institutions, the length of Model Y wire harness temporarily failed to achieve the previously predicted 700m.
However, the cost and weight caused by excessively long wiring harnesses have always been one of the pain points in the automotive industry, and this pain point is increasingly aggravated with the complexity of automotive electronics.
We believe that with the continuous popularity of OTA and domain concepts, automotive wiring harness simplification is the general trend, and the wiring harness industry will only have high voltage wiring harness as a growth point.
