What is new energy vehicle wiring harness? What are the categories of new energy vehicle wiring harnesses?

New energy vehicle wiring harness refers to the system composed of wires connecting various electrical and electronic devices of new energy vehicles. It is an important part of the new energy vehicle electrical system, and its role is to effectively organize and manage the signal transmission, energy conversion and control instruction transmission between various electrical devices. The design and manufacture of wiring harnesses for new energy vehicles need to fully consider the specificity and complexity of the electrical system of new energy vehicles to ensure the safe, stable and efficient operation of new energy vehicles. In this paper, we will introduce the definition, categories and importance of new energy vehicle wiring harness in detail. First, the definition of new energy vehicle wiring harness new energy vehicle wiring harness is connected to a variety of new energy vehicle electrical and electronic equipment wires composed of systems, including the main power harness, power battery harness, body electrical harness, charging harness. The wiring harness not only carries the function of transmitting various signals and energy, but also needs to withstand a variety of mechanical, thermal, chemical and electromagnetic environmental influences, so the wiring harness must have high reliability, high safety and high durability and other characteristics. The quality and performance of wiring harness manufacturing is directly related to the reliability and stability of the electrical system of new energy vehicles, and has a crucial impact on the performance and life of new energy vehicles. Second, the new energy vehicle wiring harness category 1. main power harness main power harness is an important part of the new energy vehicle electrical system, mainly carrying the power battery pack and the motor between the high-voltage DC power transmission task. The main power harness is mainly composed of wires, insulating materials, connectors, protective sleeves and so on. Its performance is not only related to the range of new energy vehicles, but also related to the safety and reliability of the entire vehicle.2. Power Battery HarnessPower Battery Harness is a wire system that connects the individual batteries inside the power battery pack. It is mainly composed of high-voltage wires, insulating materials, connectors, protective sleeves and so on. Power battery wiring harness is a key component in the electrical system of new energy vehicles, responsible for the transmission of high-voltage DC power, must have high reliability and high safety.3. Body electrical wiring harness Body electrical wiring harness is a system composed of wires connecting the body electrical equipment.
