What are the requirements for wires and cables for electric vehicle charging?

Electric vehicles rely on electricity to drive vehicles, so after a period of use, the batteries need to be recharged when the battery is empty. When it comes to charging electric vehicles, you have to mention the charging line of electric vehicles. Line requirements are briefly introduced.

Functional requirements The electric vehicle charging cable is the carrier connecting the electric vehicle and the charging pile, and its basic function is to transmit electrical energy. However, with the development of charging technology, to better complete the charging process, there is a need for communication between the electric vehicle and the charging pile, and automatic control when necessary. Therefore, the charging process imposes higher requirements on the charging cable. The charging cable not only needs to have the function of power transmission but also needs to transfer the status and information of the vehicle and power battery to the charging pile for real-time interaction. Under the necessary conditions, the charging Actions are controlled to complete the charging process safely and reliably.

Safety requirements At present, the safety of electric vehicles has become the focus of the industry. In the charging and discharging process of electric vehicles, due to a long time, the current intensity is large, and the frequency of cable used is high, its safety should be highly valued. The electric vehicle charging cable should have high heat resistance and aging resistance based on ensuring good insulation performance. At the same time, it should have good low smoke flame retardant properties during combustion to ensure that losses and injuries are minimized.

The current status of standards for electric vehicle charging cable products is currently based on the United States ANSI/NFPA/NECArticle400, European coordination document HD22, etc., most of China’s charging cable products are based on the IEC60245 and IEC60227 standards issued by the International Electrotechnical Commission (IEC) or The national standards GB/T5013 and GB/T5023 standards adopted for the two standards are the reference.

Because the use requirements of electric vehicle charging cables are different from traditional wire and cable, 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. Comprehensively considering 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, polyurethane materials, etc. are more suitable for charging cables Insulation materials and jacket materials have become the development direction of charging cable products.

OMG's cables are closely related to the safety of electric vehicles. OMG's high-voltage lines and charging lines are one of the core components of new energy vehicle safety systems. The safety of electric vehicles includes three aspects, the safety of power batteries, the safety of electric vehicles, and the safety of charging infrastructure. High-voltage lines and charging lines play an important role in the safety of power batteries and the safety of charging infrastructure.
