What is new energy harness? What are the domestic and international manufacturers of new energy wiring harness?

I. What is new energy wiring harness? New energy wiring harness is a special wiring harness system used in new energy vehicles such as electric vehicles, hybrid vehicles, etc. It is a circuit system composed of a variety of electronic components, wires, cables, connectors and other components. New energy vehicle wiring harness is characterized by high reliability, high durability and high protection, and is an important part of the electrical system of new energy vehicles. With the popularization of new energy vehicles, new energy vehicle wiring harness has gradually become a hot topic in the automotive industry. Here we will introduce the concept of new energy wiring harness, classification, characteristics and applications and other related content. First, the concept of new energy wiring harness new energy wiring harness refers to the wiring harness system applied to new energy vehicles. Harness refers to a collection of connectors and cables, usually refers to a part of the vehicle electrical system, consisting of wires, cables and connectors, connecting the vehicle's various electrical devices, such as engines, lights, instruments, audio, etc.. Second, the classification of new energy wiring harness according to the different types and uses of new energy vehicles, new energy wiring harness can be divided into two types of high-voltage wiring harness and low-voltage wiring harness.1. High-voltage harness high-voltage harness refers to high-voltage wiring harnesses applied to new energy vehicles such as electric vehicles, hybrid vehicles. High-voltage wiring harness is a cable system that connects high-voltage components such as battery packs, electric motors, and electronic control systems, and usually refers to wiring harnesses with a voltage greater than 60V. High-voltage wiring harness is the core part of the electrical system of new energy vehicles, and plays a crucial role in the performance and safety of new energy vehicles.2. Low-voltage wiring harnessLow-voltage wiring harness refers to low-voltage wiring harnesses applied to new energy vehicles, and usually refers to wiring harnesses with a voltage of less than 60V. Low-voltage wiring harnesses include wiring harnesses required for various electrical devices such as in-vehicle entertainment system, in-vehicle lighting system, air conditioning system, airbag system, brake system, and so on. Low-voltage wiring harness is mainly responsible for the interconnection between the electrical equipment in the car. Third, the composition of the wiring harness of new energy vehicles: 1. Wires: the wires in the wiring harness of new energy vehicles are usually made of copper or aluminum, and the wires have different diameters and lengths to adapt to different current and voltage requirements. 2. Fiber optics: fiber optics are another important component in the wiring harness of new energy vehicles. They can transmit large amounts of data, including audio, video, and other digital information.3. Connectors: Connectors are devices that link wires and devices together in a wiring harness. They can be customized according to different needs, for example, they can be made of metal or plastic and can withstand high currents and high temperatures.4. Protective Sleeving: Protective sleeving is the outer layer of protection for the wiring harness of a new energy vehicle, which prevents the wiring harness from being damaged. The protective sleeve is usually made of polyester, polyurethane and polypropylene, and can withstand high temperature, acid and alkali and other adverse environments. New energy vehicle wiring harness has a very important position in the field of new energy vehicles. With the continuous expansion of the new energy vehicle market, new energy vehicle wiring harnesses will also face higher requirements. This includes improving the reliability of the wiring harness, reducing weight and improving the efficiency of the wiring harness, etc.
