What is the High-voltage Harness of New Energy Vehicles?

The automobile harness can be divided into a low-voltage harness and a high-voltage harness as a whole. Low-voltage wiring harness is mainly used for traditional fuel vehicles, high-voltage wiring harness is mainly used for new energy vehicles. High-voltage harnesses can be configured for internal and external wire harness connections of electric vehicles according to different voltage levels.  It is mainly used to distribute the internal harness signal of the power distribution box, transmit electric energy with high efficiency and quality, shield external signal interference, etc. High voltage harness is the neural network of the high voltage systems of new energy vehicles, which is very important. Today, let's talk about what is the high-voltage harness of new energy vehicles.

Composition of high-voltage harness

The high-voltage harness of new energy vehicles is mainly composed of connectors, terminals, wires, covers, and other parts. High voltage harnesses of new energy vehicles can be configured for the connection of internal and external harnesses of an electric vehicle according to different voltage levels. It is mainly used for the signal distribution of the internal harness of the power distribution box to transmit electric energy with high efficiency and quality and shield the external signal interference. Because the high-voltage harness in the vehicle has the characteristics of large voltage/current and a large number of large diameter wires, the design of the harness faces the challenges of wiring, safety, shielding, weight, and cost.

Development of automobile wire harness

With the increasing abundance of automobile functions, the demand for automobile wire harnesses has also increased significantly, which directly leads to a significant increase in the length and weight of automobile wire harnesses, leading to a significant increase in the weight of automobiles. The difficulty of wire harness routing has been greatly improved. Therefore, it is necessary to optimize automobile wire harnesses from quality to wiring to meet the booming demand. We believe that automobile wire harnesses will mainly develop in the following aspects:

First: The lightweight of automobile harness market is the main tone of future development.

Second: the FPC scheme is widely adopted in mainstream electric vehicle models. FPC has become a trend to replace traditional wire harnesses.

Third: Automation. The structure of automobile wiring is complex. At present, 95% of wire harnesses need to be produced manually, with low production efficiency. It is a typical labor-intensive industry. Human cost has become one of the main factors restricting enterprises to expand production capacity and achieve scale effects. At present, most automobile wire harness manufacturers are still at the stage of automatic production that relies on local advanced equipment to complete some processing links, and intelligent manufacturing has not yet been popularized and developed. In the future, with the gradual integration of automobile wire harnesses and the continuous progress of production technology, intelligent manufacturing is expected to run through the whole process of automobile wire harness design, production, warehousing, logistics, management, and service.
