5. Lightweight is the main tone of future automotive wiring harness development

As an important part of the vehicle, the automotive wiring harness accounts for 2% of the total vehicle weight, and continues to expand with the increase of automotive electronic equipment. The lightweight of the wiring harness is more and more important to reduce the energy consumption of a single vehicle. The weight of copper wires in automotive wiring harnesses accounts for 75%, which is the main lightweight direction.

The lightweight of automotive wiring harness mainly includes material lightweight, structural lightweight and layout optimization. 1) Material optimization, the conductive properties of aluminum wires are close to copper, and the weight is lighter, and they are more and more used in power lines and signal lines; 2) Structure optimization, the signal lines use ultra-thin copper wires to ensure current conduction. At the same time, it can reduce the weight of the wiring harness by 50%; 3) Layout optimization, the top auto parts supplier Bosch and the first-class OEM BMW have put forward the prospect of the domain control architecture and power distribution architecture, and the new energy vehicle leader Tesla On the Model3 (parameters | pictures), the mass production of the domain control architecture and the power distribution architecture has been realized.
