IEC 62893 Technical Standard for Electric Vehicle Charging Cables

With the rapid development and popularity of electric vehicles, the construction of charging facilities has become increasingly important. As an important part of connecting electric vehicles and charging piles, the quality and safety of charging cables are particularly critical. In order to ensure that the safety, reliability and performance of charging cables meet the requirements, the International Electrotechnical Commission (IEC) has formulated a series of standards for electric vehicle charging cables. IEC 62893 is a standard for DC charging cables for electric vehicles released in November 2017. It is applicable to charging modes 1-4. This standard covers the design, manufacturing, testing and use of charging cables and aims to ensure the safety, reliability and interoperability of charging cables during the charging process.

The following are some important contents in the IEC 62893 standard:
Construction and Materials: IEC standards specify requirements for the construction and materials used of charging cables. For example, the conductor material should have good electrical conductivity and durability; the insulation material should be EVI-1 (CC/CP wire only) and EVI-2, which have good insulation performance and high temperature resistance; the sheath layer should be EVM-1 category Polyurethane elastomer material, EVM-2 (cross-linked type) and EVM-3 (cross-linked type); the minimum signal line is 0.5mm².

Rated voltage and current: IEC standards specify the rated voltage and current range of charging cables. The voltage level is 300/500V, 450/750V AC; 1000V DC. The selection of these parameters should be reasonably determined based on the charging needs of electric vehicles and the requirements of charging facilities.

Provide customers with electric vehicle charging cable solutions based on specific needs. To sum up, the IEC 62893 standard provides important guidance for the design, manufacture and use of electric vehicle charging cables, ensuring that the safety, reliability and performance of charging cables comply with international standards. In the field of electric vehicle charging, following IEC standards is a key step to ensure the safe operation of charging facilities and user charging experience.
