In the traditional distributed automotive electronic and electrical architecture, the information transmission and control of the sensors and various electronic and electrical systems in the vehicle are completed by the distributed automotive electronic controller (ECU). The increasing number of Electronic Control Units (ECUs) in vehicles increases the difficulty of wiring power and data distribution. Domain controllers and the centralized architecture within the domain came into being.
As the main carrier of power output on electric vehicles, high-voltage wiring harness is one of the key components for vehicle performance and safety. The high-voltage wiring harness in the car is mainly used to provide high-voltage and strong power supply for new energy vehicles. It is a high-safety component in new energy vehicles. It has the characteristics of high voltage/high current and large number of large diameter wires. Compared with in-vehicle high-voltage power transmission, it has higher requirements on the electrical performance, shielding performance, mechanical performance and durability of the wiring harness.
