The requirements of electric vehicle charging for cables are mainly reflected in the following aspects:
First of all, the cable needs to have a high degree of safety performance, which is the basis for ensuring that the charging process does not occur short circuit, fire and other dangerous situations. Therefore, the cable should have high temperature resistance, flame retardant and other characteristics to ensure that it can remain stable and safe under a long period of high load work. Secondly, the cable needs to be able to withstand high voltage because electric vehicles require high voltage to charge. This means that the insulation of the cable should be good enough to prevent leakage and avoid safety accidents.
In addition, since electric vehicle charging cables require frequent unplugging and plugging operations, the cables also need to have high abrasion resistance. This ensures that the cable will not deteriorate in the harness and the core will not fall off after a long period of use, thus maintaining its good performance. The size of the cable is also an important factor to consider. The size of cables used for EV charging varies depending on the model and charging power, and choosing the right cable specification can ensure charging efficiency and safety. Generally speaking, vehicles with higher charging power need to choose thicker cables.
Finally, the cables also need to have the function of power transmission and communication transmission in order to interconnect between charging piles and electric vehicles, between electric vehicles and the power grid, and between charging devices. This requires the cable to have stable transmission performance to ensure a smooth charging process.

For electric vehicle high-voltage cables, obtaining E-Mark certification means that their quality and performance have reached the recognized standards of the European market. Through a rigorous testing and auditing process, the certification body will conduct a comprehensive assessment of the electrical, mechanical and environmental performance of high-voltage cables, which helps to increase consumer trust in the product. At the same time, E-Mark certified high voltage cables are also required to meet certain environmental requirements, such as the use of materials that comply with environmental standards such as RoHS 2.0 and REACH. In addition, E-Mark certification also helps to enhance the image and competitiveness of the enterprise, but also a reflection of the product quality management system of the enterprise, which helps to improve the management level and operational efficiency of the enterprise, and can attract more customers and partners.
The specific process of E-Mark certification usually includes the steps of certification application, data preparation, product testing, submission audit, factory inspection and certificate issuance. During the application process, companies need to prepare relevant technical data and samples, and prepare the certification data according to the requirements of the issuing country. The samples to be tested will be sent to the designated laboratory for formal testing, and the test report will then be submitted to the Ministry of Transportation of the issuing country for audit. The first application also needs to undergo a factory inspection to ensure that the production process and product quality comply with the standards. After the audit, the European national transportation department will officially issue the E-Mark certificate.

It aims to ensure the safety performance of electrical appliances and to protect the rights and safety of consumers.
Rechargeable cables are electrical appliances that must be certified by PSE if they are to be sold on the Japanese market. According to Japan's Electrical Appliance and Material Safety Law, charging cables are categorized as â??Specified Electrical Appliancesâ?? and are required to obtain the diamond-shaped PSE mark before they can be manufactured or imported.The PSE certification standard specifies the electrical safety performance of charging cables in detail, including the requirements for voltage withstand and insulation to ensure that they can effectively isolate the power supply in the event of electrical faults or other abnormal conditions, reducing the probability of safety accidents. abnormal conditions can effectively isolate the power supply and reduce the probability of safety accidents.
In addition, the PSE certification standard focuses on product reliability and durability. The standard requires that charging cables can maintain good safety performance and are not prone to failure or damage during their normal service life. For the certification of charging cables, the PSE standard requires that the insulation of the cable be resistant to abrasion and high temperature to ensure that users are not exposed to safety threats during use. Japan PSE certified charging cables are usually made of high-quality materials, such as high-strength insulating outer layer, stretch-resistant cores, and stable connectors, to ensure that the power transmitted during charging is stable, while avoiding safety hazards such as leakage and overheating. The PSE certification standard also focuses on the environmental performance of the products. The standard requires charging cables to use environmentally friendly materials in the production process, free of hazardous substances, and can effectively save energy, reflecting the importance of sustainable development and environmental protection.

The insulating material of high-voltage cables has a decisive influence on the safety and efficiency of power transmission. The following is an analysis of two common insulation materials:
1. Polyvinyl chloride (PVC) insulated power cables:
 Advantages: Good heat and corrosion resistance, suitable for a wide range of environments. The nominal thickness prevents current leakage and improves safety.
 Disadvantages: Easy to deteriorate under high temperature environment, may need to be replaced periodically.
2. Cross-linked polyethylene (XLPE):
 Advantages: Higher heat resistance and voltage resistance, suitable for high voltage power transmission. Stable insulating properties, not easy to age in long-term use.
 Disadvantages: Higher cost compared to PVC.
The following factors need to be considered when selecting insulation materials:
Environmental conditions of power transmission: e.g. temperature, humidity, chemical corrosion, etc.
Operating voltage of the cable: different insulation materials are suitable for different voltage levels.
Economic cost: including material cost, installation cost and maintenance cost.
Long-term performance: including the aging rate and durability of the material.
Choosing the right insulation material is essential to ensure the safety and reliability of power transmission. Therefore, it is important to make a professional selection based on a full understanding of the material properties, taking into account the specific application scenarios and needs.
Electric vehicles need fast and safe charging to meet users' needs. Firstly, from a practical point of view, fast charging can greatly shorten the waiting time of vehicle owners and enhance the experience of use. For example, on long-distance trips, if the charging time is too long, it will not only affect people's travel plans, but also may trigger users' range anxiety. Secondly, safe charging is the basic need of every car owner. After all, frequent charging accidents will greatly reduce people's confidence in EVs and negatively affect their market prospects. Currently, the market achieves high-efficiency charging of trams through liquid-cooled charging technology:
1. Heat dissipation principle:
