With the development of new energy vehicle technology, the requirements for automotive electrical appliances are becoming increasingly high, and as one of the core components of automotive electrical appliances, the requirements for automotive wiring harnesses are also increasing. The layout of automotive wiring harnesses has a significant impact on the reliability and stability of new energy vehicles. Therefore, how to scientifically, reasonably, safely, aesthetically pleasing, and easy to maintain and install wiring harnesses for new energy vehicles is a key focus. The article focuses on the layout of wiring harnesses for new energy vehicles, clarifying the design principles for high-voltage and low-voltage wiring harnesses, and providing reference for the layout of wiring harnesses for new energy vehicles.

Automotive wiring harness is an important component that connects electronic and electrical equipment such as car power supply, actuators, and sensors, and is also considered the "nervous system" of the car.

If there is no car wiring harness, the car circuit will also disappear, resulting in the inability to achieve all electrical functions of the car. The current trend of electrification, intelligence, and networking in automobiles has greatly promoted the development of automotive wiring harnesses, while the requirements for automotive wiring harnesses are becoming increasingly high. In recent years, new energy vehicles have flourished, and their dependence on automotive wiring harnesses has increased. Therefore, stricter requirements have been put forward for the layout of automotive wiring harnesses.

Automotive wiring harness is an important component of new energy vehicle electrical parts, and its performance has a crucial impact on the reliability and stability of new energy vehicles. Therefore, it is necessary to scientifically design the layout of automotive wiring harness to further improve its reliability. In this article, taking new energy vehicles as an example, the principles of wiring harness layout for new energy vehicles are introduced, providing some reference and assistance for the subsequent wiring harness layout of new energy vehicles.
