With the development of productive forces, the product structure is becoming more and more complex, and commodities are generally sold to users through the circulation field. At this time, it is difficult for users to judge the quality of products based on their capabilities and experience. To reassure users, producers adopted countermeasures to provide guarantees for commodities.

According to the "Standardization Law of the People's Republic of China", "Implementation Regulations of the Standardization Law of the People's Republic of China" and the "Regulations on the Administration of Enterprise Product Standards" by the General Administration of Quality Supervision, Inspection and Quarantine, if the products produced by the enterprise do not have national standards, industry standards or local standards, the enterprise products should be formulated Standards are used as the basis for production and trade; for existing national standards, industry standards, or local standards, enterprises are encouraged to formulate enterprise product standards that are stricter than national standards, industry standards, or local standards.

The formulation of enterprise product standards is the quality assurance made by the enterprise to the public (consumers); it is also a constraint on the enterprise. The enterprise product standard is formulated and published by the enterprise and is responsible for the content and implementation consequences of the product standard.

1. The main international new energy cable standards:

Charging cable standard:

Standards for high-voltage lines used inside cars：

OMG is an advanced enterprise integrating R&D, production, sales and service. It is a powerful enterprise in the alternative energy industry of new energy electric vehicles. Since 2009, it has expanded a lot of resources for independent research and development of new energy electric vehicle replacement products. OMG specializes in the field of new energy vehicles. After repeated accumulation and research, OMG has professionally served the first-line customer groups, car companies, battery companies, connector harness companies, charging pile companies and energy storage equipment companies. Actively participated in the compilation of Guangdong local standards for high-voltage lines and charging lines "Electric Vehicle Charging Cable" GB/T; "Electric Vehicle AC 1.5kv High-voltage Flexible Cable".

2. Advantages and disadvantages of charging cable standards

⑴GB/T 33594

advantage:

①. The performance of insulating sheath material and the finished product is relatively complete, and the reliability is high.

②. The material is more selective.

③. In line with the national conditions of the Chinese market.

Disadvantages:

①. The high-temperature resistance of the material and the entire cable can be considered to be improved.

⑵EN 50620:

advantage:

①. The complete performance index of insulation and sheath materials.

②. All products are halogen-free, in line with the concept of new energy green and environmental protection.

Disadvantages:

①. The combination of insulation and sheath material is single, with less selectivity.

②. There is no optional DC charging cable in the product.

③. Lack of scratch resistance, extrusion resistance, damp heat, high and low-temperature cycles, and other tests.

⑶UL 62:

advantage:

①. A wide range of materials, PVC, TPE, CPE, etc. can be used.

②. Focus on environmental resistance, electrical performance, combustion, etc., such as 90-degree long-term insulation resistance, relative capacitance, and stability factor, VW-1 test, etc.

Disadvantages:

①. The specifications and specifications in the standard are confusing.

②. Lack of tests to evaluate the actual use of cables, such as rocking test, liquid resistance test, high and low-temperature cycle, damp heat test, tear-resistance test, etc.

Since domestic standards cannot meet some special requirements of customers, we have established enterprise standards. Enterprise standards will be higher than national standards in some aspects to meet customers' high requirements for products.

OMG's internal control standards are high, and product design and production are implemented only for safety. OMG safety standards are based on national standards and more stringent corporate standards.
