The wire and cable industry is an industrial basic industry and occupies an extremely important position in my country's national economy. With the adjustment of my country's energy structure, the electric vehicle industry will show explosive growth, which has greatly stimulated the rapid development of the transmission and distribution industry, and the wire and cable industry will usher in the spring of development.

On the basis of ensuring good insulation performance, electric vehicle charging cables should have high heat resistance and aging resistance. At the same time, it should have good low smoke flame retardant properties during the combustion process to ensure that losses and injuries are minimized.

At present, the production base of electric vehicle charging cable products is mainly ANSI/NFPA/NECArticle400 in the United States, European coordination document HD22, etc. The vast majority of China's charging cable products are based on the International Electrotechnical Commission (IEC), two standards of IEC60245 and IEC60227. These two standards are equivalent to national standards GB/T5013 and GB/T5023. The Article400 charging cable standard in the United States was established relatively early, mainly relying on the product standard established by the UL62 flexible cable standard of the American UL company. The insulation materials specified in the standard include polyvinyl chloride (PVC), thermoplastic elastomer (TPE), polypropylene materials such as ethylene (EPR), and the outer skin materials include PVC, chlorinated polyethylene (CPE), TPE, etc. There are many types of materials and the models in the standard. The specific structural parameters are basically consistent with UL cable products. It is relatively broad, and there are no strict restrictions on materials and structures, as long as it can meet the basic performance requirements of the charging cable.

Electric vehicle charging cable products produced and manufactured in Europe are mainly produced in accordance with European standard coordination documents HD22.4 and HD22.12. HD22.4 stipulates that the rated voltage is 450/750V and below, and the ethylene propylene rubber insulation and ethylene-propylene rubber/chloroprene rubber and their equivalent mixture sheathed flexible cables, HD22.12 stipulates that the rated voltage is 450/750V and below. EPR/chloroprene rubber and its equivalent mixture sheath resistant to ethylene-propylene rubber insulation and sheath.

Because the use requirements of electric vehicle charging cables are different from traditional wire and cable, it is difficult for the current wire and cable standards 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.

The industry standards fully refer to the requirements of GB/T25085-2010 and GB/T25087-2010. Ogilvy & Mather has many years of experience in automotive high-pressure products and product-specific environments. When referring to these two standards, reference is also made to GB/T12528-2008 rated 1500V AC rail locomotive standard and CQC-1103~1105 charging line standard. Mainly proposed to improve voltage resistance, insulation volume resistivity, flame retardancy, tear resistance, flexibility, etc.
