Electric car charging cable overview
The electric car charging cable is the carrier connecting the electric vehicle and the charging pile, and its basic function is to transmit electric energy. However, with the development of charging technology, in order to better complete the charging process, it is necessary to do a good job of communication between the electric vehicle and the charging pile, and to do automatic adjustment when necessary. Therefore, the charging process places higher demands on the charging cable. The electric car charging cable not only has the function of power transmission, but also transmits the status and information of the vehicle and the power battery to the charging pile for real-time interaction. When necessary, adjust the charging response to complete the charging process safely and reliably.
In today's society, the safety factor of electric vehicles has become the focus of the industry. Due to the long time, high current intensity and high frequency of cable use, the charging and discharging process of electric vehicles should be highly valued. electric car charging cable should have high heat resistance and aging resistance on the basis of ensuring good insulation performance. to the minimum.
Electric car charging cable specification standard
At present, the production and manufacture of electric car charging cable products are generally based on the American ANSI/NFPA/NECArticle400, the European Harmonization Document HD22, etc. The vast majority of electric car charging cable products in China are based on the IEC60245 and IEC60227 specifications issued by the International Electrotechnical Commission (IEC) or the national specifications GB/T5013 and GB/T5023, which are equivalent to these two specifications. The Article400 charging cable specification in the United States was formulated earlier in the same period, and the key relies on the product specification established by the UL62 flexible cable specification of the UL company in the United States. The insulating materials specified in the specification include polyvinyl chloride (PVC), thermoplastic elastomer (TPE), polypropylene Ethylene (EPR) and other materials, sheath materials include PVC, chlorinated polyethylene (CPE), TPE and other materials. There are many kinds of materials and models in the specification, and the main parameters of the specific structure are basically the same as those of UL cable products. Performance needs can be. The electric car charging cable products produced and manufactured in Europe are mainly manufactured in accordance with the European Norm Harmonization Documents HD22.4 and HD22.12. HD22.4 specifies ethylene-propylene rubber insulated and ethylene-propylene rubber/neoprene rubber and its equivalent mixture sheathed flexible cables with rated voltages up to and including 450/750V. HD22.12 specifies heat-resistant ethylene-propylene rubber insulated and ethylene-propylene rubber/neoprene rubber and its equivalent mixture sheathed flexible cables with rated voltages up to and including 450/750V.
Electric car charging cable manufacturer recommendation
Since the use requirements of electric car charging cable are different from those of traditional wires and cables, the current wire and cable standards are difficult to cover all the use requirements of charging cables. Therefore, it is necessary to formulate independent charging cable product standards to promote the healthy development of the industry. Taking into account the mechanical performance requirements, electrical performance requirements, safety, environmental protection and service life requirements of charging cables, new low-smoke halogen-free flame retardant materials, polyester elastomers, and polyurethane materials are more suitable for electric car charging cable. Insulation materials and sheath materials have become the development direction of charging cable products.
