EVCOME EV charging stations for better life---Top EV charging stations manufacturers & suppliers in China.
The production and application of new energy vehicles have great advantages in terms of environment and noise. Electric vehicle charging pile cables also came into being, which immediately brought various questions. So let's briefly introduce electric vehicle charging pile cables. 1. What is a charging pile cable? Therefore, electric vehicle charging pile cables are used to connect charging guns and charging infrastructure to transmit electric vehicles, and are equipped with a certain number of signal lines. control line. Power supply auxiliary line, etc., to ensure accurate control of the entire charging process. Safe and correct operation. Second, the development status of charging pile cables. Since 2018, the trend of the new energy vehicle market has shown a good start. In January, sales of new energy passenger vehicles reached 31,638 units, a year-on-year increase of 483%. From the perspective of sales data, the market situation is very good; from the perspective of industrial layout, China's auto investment in 2017 exceeded 450 billion, and the layout and investment in 2018 far exceeded last year; Policies are conducive to the development of new energy vehicles. From the perspective of market, capital, policy and other dimensions, the development of new energy vehicles has entered a white-hot stage. The development momentum of new energy vehicles is so fast, we can imagine that charging pile cables should also be well developed as auxiliary products. But things may not be as smooth as we think. It is understood that the regulations of the charging pile industry are that the products of gun companies or cable companies should provide at least a two-year warranty period, and all products that have problems during the warranty period should be replaced free of charge. Under the terms of this transaction, the automaker. operator. Even the technical department of a pile company can easily investigate the quality of various products in the supply chain, because if there is a problem, they will replace it for free anyway. Manufacturers of charging guns and cables, which are the most frequently used charging piles, take a lot of risk. It is said that although the charging pile market looks like a gold mine, many large wire and cable factories have not fully participated, because the entire supply chain of charging piles has entered the stage of price war of blood and blood. Many cable manufacturers may not have tried the sweetness of sugar cane. 3. The scope of application of EV charging pile cables. The EV charging pile cable can be used indoors or outdoors. When used outdoors, the charging pile cable should meet the erosion of high cold, sunlight, rain and automobile oil, which requires the cable to have special properties such as UV resistance, ozone resistance, high and low temperature resistance, and chemical corrosion resistance. During use, the charging pile cable EV will be frequently stretched, bent or crushed by electric vehicles, which also requires the charging pile cable to meet special mechanical performance requirements, such as bending, bending, and vehicle rolling tests. Fourth, the use characteristics of EV cables. 1. During the charging process, the cable has the characteristics of high pressure resistance, high temperature resistance, electromagnetic interference resistance, stable signal transmission, bending resistance of more than 10,000 times, wear resistance of more than 5,000 times, oil resistance, water resistance, acid and alkali resistance, UV resistance and other characteristics. 2. The concentricity is good, up to more than 80%, so that the cable's high-voltage resistance performance is stable and reliable. 3. The product is small, and the bend is 4D, which is convenient for use between wiring in narrow spaces. The product has high flexibility and is very convenient to use on-board wiring. 4. The rated temperature of the product is 125°C, which is a great technological progress and improvement for the one-time molded soft insulating material, and is very important for ensuring the flexibility of the cable and improving the current-carrying capacity of the cable. .
