Safety performance requirements for new energy charging pile cables

Author: EVCOME-EV Chargers Manufacturers

With the huge pressure on energy and environment in today's society, people are constantly seeking clean energy to replace traditional fuels in order to improve the deteriorating traffic emission situation. Therefore, the emergence and application of new energy electric vehicles has gradually become the focus of governments and automobile manufacturers. The development and construction of new energy electric vehicles and power distribution facilities is a key project for national development, and the market demand for new energy charging pile cables has greatly increased. The new energy charging pile should be able to judge whether the charging connector and the charging pile cable are connected correctly. When the charging connector is correctly connected to the electric vehicle battery system, the charging pile allows the charging process to start; when the charging pile finds that it is abnormally connected to the electric vehicle battery system, it immediately stops charging and sends an alarm message. Charging piles should have charging protection functions: abnormal communication protection, insulation resistance inspection protection, emergency shutdown protection, abnormal charging current protection, abnormal charging protection, abnormal voltage protection, leakage protection, charging gun over-temperature protection, and abnormal battery temperature protection. Correspondingly, the charging cable, as the current carrier connecting the electric vehicle and the charging pile, not only needs the information transmission between the two, but also needs to control the charging. On the basis of ensuring excellent insulation performance, it has high aging resistance, heat resistance, oil resistance and weather resistance. The flexibility and mechanical properties of the cable are also required since the cable is often bent and dragged during use. The 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 of UV resistance, ozone resistance, high and low temperature resistance and chemical corrosion. evcome selects new energy charging pile cables.
