The development trend of new energy vehicle wiring harness

1. Low-voltage wiring harness to enhance the level of automation to improve gross margins automotive low-voltage wiring harness models vary greatly in their own characteristics, 70% man-made resulting in lower gross margins and production efficiency, the future direction of development is to seek customization in the standardization of the part, as well as cable pre-processing and pre-installation process, and constantly improve the level of automation to improve efficiency and gross margins. The industry, such as Laini, assembly line tried to work station and wire board at the same time to improve efficiency. Second, such as Kunshan Hukuang, in the incoming material into the warehouse, parts out of the warehouse on the line, small line pre-assembly and other links to try to automate the production, improve production efficiency has made good progress. 2. high-voltage wiring harness scale to the wiring harness plant to focus on the lightweight attempts to high-voltage wiring harness manufacturers are many and varied, wiring harness plants and parts manufacturers are involved in small batch production, the future direction of development is the effect of scale to the wiring harness plant to concentrate on the Trend, for the gross profit and quality of the product is to enhance. Harness lightweight is also a major car factory in the direction of trying, the main weight of the harness lies in the copper cable, how to rationally select the cable application and the application of aluminum wire is one of the topics of lightweight in the future.3. High-voltage connector systematic development to enhance the competitiveness of foreign vendors, only the Tyco electronics high-voltage connector R & D investment early, the product has become a system, but localization is still in progress, the price is more expensive; Domestic manufacturers in the new energy vehicle development in the early stages of the use of other industries high-voltage high-current connectors used in automotive, quickly seized the market to take advantage of the opportunity to do the next step is to gradually make the new energy automotive high-voltage connectors into a complete product line, from small current to high-current, from the single pin to the multi-pin, from right-angles to 90-degree connection, a variety of product lines to do completely, on the one hand, to enhance their competitiveness, on the other hand, to strengthen the bonding with vehicle manufacturers. High-voltage silicone rubber cable development to make up for the technology and capacity gaps high-pressure silicone rubber cable is the direction of the development of new energy vehicles, on the one hand, due to the convenience of the wiring of the car body, on the other hand, due to the safety performance of the high temperature resistance, foreign manufacturers in China are not production lines, automotive silicone wire are imported, long lead times, expensive, domestic manufacturers are stepping up the development to make up for the technology and production capacity gaps, foreign manufacturers are also in the process of developing a new product line. Capacity gaps, foreign manufacturers are also in the action of localization, the subsequent competition will be more intense.
