Development Trend of New Energy Power Vehicle Wiring Harness

According to data, the earliest automotive wiring harness can be traced back to the early 20th century. At that time, the wires of automobile electrical systems were all handmade, and there were no unified specifications and standards. This situation not only increases manufacturing costs, but also limits the development of automotive electrical systems. In order to solve this problem, automobile manufacturers began to explore a more efficient and standardized form of cable organization, and automobile wiring harnesses came into being.

The automobile wiring harness is the main body of the automobile circuit and has no wires. The electronic control system in modern cars is closely related to the wiring harness. The human body is used to realize the functions of ECU, sensors and actuators. The ECU is equivalent to the human brain. Sensors are equivalent to sensory organs, and actuators are equivalent to movement organs. Obviously, without nerves and blood vessels, the mind and various organs cannot function properly. With the continuous improvement of automobile safety, comfort and environmental protection requirements, the number of circuits and power consumption in automobiles has increased significantly, making how to arrange a large number of wire harnesses more effectively and rationally in a limited space has become a difficult problem in automobile manufacturing. This paper briefly introduces the current status and development trends of automotive wiring harness lightweighting, modularization and in-vehicle communication technology.

With the continuous development of science and technology, future development will be more lightweight and modular. The continuous development of automobile wiring harnesses and vehicle-mounted communication systems will be more widely used in automobiles. With the development of new network communications, automobiles will be more intelligent and data-driven. Transmission is more reliable, and the requirements for wires will continue to increase.
