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.

The standards for high voltage cables for electric vehicles cover a number of aspects to ensure that the cables can work safely and stably in high voltage and high current environments. Here are some interpretations of the standards for high voltage cables for electric vehicles:
Voltage Requirements: According to the voltage level of electric vehicles, the rated voltage of the whole vehicle is usually DC1000V or AC660 V. The rated voltage of the high-voltage wiring harness shall be slightly higher than the rated voltage of the whole vehicle, so as to ensure that it can work stably under all kinds of working conditions.
Voltage resistance: The cable should be able to withstand high voltage testing to verify its dielectric strength. In the case of the harness and components off, the harness to the car body should be able to withstand a certain voltage and frequency of the test, without breakdown.
Insulation resistance: Insulation resistance is an important indicator of the insulation performance of cables. According to the standard, the insulation resistance of the cable should be greater than a certain value under a specific test voltage to ensure that the cable will not leak or short-circuit when working.
Salt spray requirements: the cable should also pass the salt spray test to verify its corrosion resistance in harsh environments. After a certain period of time in the salt spray test chamber, the cable should be able to work normally without performance degradation or appearance damage.
In addition, the standard for high-voltage cables for electric vehicles also involves the structural design, material selection and manufacturing process of the cable. The conductor cross-section, conductor materials, insulation materials, shielding layer, etc. of the cable need to meet the relevant requirements to ensure the performance and safety of the cable.
Overall, standards for high voltage cables for electric vehicles are key to ensuring that cables can work safely and stably in high voltage and high current environments. These standards not only cover the basic performance requirements of the cables, but also include the testing requirements of the cables under various extreme conditions to ensure that the cables can meet the needs of electric vehicles in actual use.OMG' is certified by the ISO 9001:2015 and IATF 16949:2016 systems, and OMG' in-vehicle High-voltage cable products implement international standards such as ISO6722-1, ISO6722-2, ISO14572, LV216, ISO19642, UL758 (UL3820\UL30088), etc. It also widely produces Chinese standard products mainly based on QC/T1037, and on the basis of which, it also introduces enterprise standards which are higher than the industry standards.

While ensuring the safety of the charging process of electric vehicles, it also greatly improves the charging efficiency. It helps to shorten the charging time and enhance the user's charging experience. At the same time, the oil-cooled charging cable is able to withstand long periods of high-power charging, reducing the risk of cable aging and damage due to overheating, thus extending the service life of the cable and reducing maintenance and replacement costs.
1. Transmission capacity of charging cable: The transmission capacity of charging cable directly affects the charging speed of fast charging. Fast charging usually adopts DC charging mode, which requires high charging power. Therefore, charging cables need to have sufficient conductivity to stably transmit high power. OMG' focuses on providing electric vehicle charging cable solutions, and selects high-quality charging cable materials and appropriate cross-section area of wires according to the actual demand, which can reduce the resistance of the cable, improve the charging efficiency and realise fast charging.
2. Durability of charging cables: During fast charging, charging cables are subject to high currents and frequent plugging and unplugging operations, so their durability is critical. Cables with poor durability are prone to damage or overheating, thus affecting charging effect and safety. In order to improve the durability of charging cables, OMG' puts the use of high-quality materials and structural design into production, increasing the tensile strength and abrasion resistance of the cables, as well as paying attention to the correct operation and maintenance in the process of use.
3. Temperature management: During fast charging, the charging cable and connector may generate a certain amount of heat, which requires effective temperature management. Excessive temperature will affect the conductivity and safety of the charging cable, and even lead to potential safety hazards. Therefore, charging cables should have good heat dissipation performance, and OMG' improves the temperature management capability by optimising the heat dissipation structure and increasing heat dissipation materials. Our liquid-cooled charging cables utilise liquid-cooling technology to incorporate a liquid-cooling circulation system inside the cable, and a structural form that allows the cooling system and charging system to co-exist and function together through a sealed circulation connection inside the charging gun. This allows the cable to maintain a low and constant temperature during the charging process, overcoming the thermal damage caused by heat generation to the charging gun, charging cable and charging pile, thus increasing the DC charging current.
4. Safety considerations: charging cable as an important link in the transmission of electricity, safety is a factor that can not be ignored. OMG's design and manufacture of charging cables, follow the relevant safety standards and norms, cables are in line with the European standard, the American standard, the Japanese standard, the Chinese standard and other standards in the industry, to ensure that the cable's insulation and voltage resistance, to prevent electric shocks and fires and other safety issues occurring.
New energy charging generally has three ways, portable charging, home-style charging and public charging piles, different charging methods are suitable for different scenarios and charging needs. But no matter which charging mode, the pursuit of charging reliability is the top priority. Electric vehicle charging cables are used to connect electric vehicle charging devices with the charging infrastructure, thereby transmitting power to the electric vehicle, and are equipped with a certain number of signal lines, control lines, power supply auxiliary lines, etc. to ensure that the entire charging process is accurately controlled and operated in a safe and error-free manner. Charging cables are generally used in charging stations, parking lots, hotels, neighborhoods, garages and other areas, and portable charging cables can be placed in the car. Charging cable as an important carrier of power transmission, for different charging modes need to choose the appropriate cable to better ensure the efficiency and safety of charging.
Portable charging and home charging generally use alternating current (AC), which is slower to charge, while the majority of public charging piles use direct current (DC), which focuses on the efficiency of charging. As home chargers are usually installed and used by individuals, they have higher safety requirements. Therefore, the cables used in home charging piles undergo strict safety certification and are waterproof, high temperature resistant and fireproof. In addition, the cable length of home chargers is generally longer to accommodate different parking locations. Cables used in public charging piles, on the other hand, require greater durability and stability. Because public charging piles are used more frequently, the cables need to withstand more plugging and unplugging and the influence of the external environment. Therefore, the cables used in public charging piles are made of more wear-resistant, pressure-resistant and corrosion-resistant materials to ensure a long service life and stable charging effect.

In this paper, we will focus on the common insulation materials and their characteristics of high-voltage cables, and analyze the advantages and disadvantages of different types of insulation materials by comparing and contrasting them, and make an in-depth analysis from the perspectives of material properties and applicable scenarios.
First, let's take a look at polyvinyl chloride insulated power cables. As a common insulating material, PVC has good heat resistance and corrosion resistance, and is suitable for power transmission under various environmental conditions. The nominal thickness of its insulation can also effectively prevent current leakage and improve the safety of the cable. However, PVC insulated power cables also have some disadvantages, such as easy deterioration in high temperature environments, and need to be replaced periodically to ensure the stability of power transmission.
Another common insulating material is cross-linked polyethylene. Compared with PVC, cross-linked polyethylene has higher heat and voltage resistance and is suitable for high-voltage power transmission. Its insulating properties are stable, and it is not easy to deteriorate in long-term use, making it an excellent insulating material. However, cross-linked polyethylene is relatively expensive and needs to be selected according to specific scenarios.
When selecting insulation materials for high-voltage cables, various factors need to be considered according to the actual power transmission scenario. The properties and application scenarios of different insulating materials differ significantly, so it is crucial to choose the right insulating material. Only after a full understanding of the advantages and disadvantages of various insulating materials, and according to the specific needs to choose, can ensure the safety and stability of power transmission.
In summary, the selection of insulation materials for high-voltage cables has an important impact on power transmission, and it is crucial to choose the right insulation materials for different scenarios. Only by choosing under a professional, objective and analytical perspective can we ensure the smooth progress of power transmission. We hope that this article can help you better understand the insulation materials of high-voltage cables and provide some reference for the development of the power transmission field.

Firstly, the high-voltage cables of new energy vehicles generally match the voltage level of the battery pack. According to the design of the vehicle's electrical system and voltage requirements, the appropriate voltage level is selected, for example, common high-voltage cable voltage levels are 500V, 800V and so on. Secondly, the rated current of the high-voltage cable should be able to meet the charging and driving requirements of the electric vehicle. According to the power and charging requirements of the vehicle, select the high-voltage cable with sufficiently large rated current capacity to ensure charging efficiency and driving performance. The insulation material of the high-voltage cable should have good insulation and high temperature resistance to prevent current leakage and short-circuit accidents. Commonly used insulating materials include polypropylene, polyethylene and cross-linked polyethylene. According to the use environment and temperature requirements of the vehicle, choose the appropriate insulation material. In addition to this, high-voltage cables are subject to friction, extrusion and environmental climate during use. Therefore, high-voltage cables with good abrasion and weather resistance should be selected to extend their service life and reliability.
When selecting high-voltage cables, it is important to choose the appropriate length of high-voltage cable according to the design and layout of the vehicle and to ensure that the connection method and connectors meet the requirements of the vehicle system. Suitable lengths and connections simplify the installation process and increase the reliability of the cable. It is important to ensure that the cables comply with relevant safety certification standards and regulations, such as national or regional product certifications, International Electrotechnical Commission (IEC) standards, etc. These certifications guarantee the quality and safety performance of high-voltage cables.

EVI-1 and EVI-2: EVI is the name given to halogen-free insulating compounds in the IEC62893 and EN50620 standards. Only EVI-2 can be used to insulate power lines, while EVI-1 and EVI-2 can be used to insulate control/signal lines.The performance requirements of EVI-1 and EVI-2 are different, for example, the standard requirements are: tensile strength of EVI-15N/mm², elongation at break 300%, while the tensile strength of EVI-2 is 8.0N/mm, and the elongation at break 200%. The key difference is that EVI-1 has a requirement for high temperature pressure testing and EVI-2 has a requirement for thermal extension testing. So EVI-1 needs to be a thermoplastic material (TPE) and EVI-2 needs to be a halogen-free cross-linked material (XLPO).
EVM-1 and EVM-2: EVM is the name of halogen-free sheathing compounds for cables in IEC62893 and EN50620 standards.EVM-1 is applied to Z5 of EN50620 and 121 and 123 and 126 of IEC62893, and EVM-2 is applied to Z6 of EN50620 and 122 of IEC62893.The performance requirements of EVM-1 and EVM-2 are different. EVM-2 performance requirements are different, for example, the standard requirements: EVM-1 tensile strength â?¥ 20N/mm �², elongation at break â?¥ 300%, tear resistance â?¥ 40N/mm �²; while EVM-2 tensile strength â?¥ 10N/mm �², elongation at break â?¥ 150%, tear resistance â?¥ 10N/mm �², the aging temperature of the mechanical properties test after aging is different, the most important differences between The key difference is that EVM-1 has the requirement of thermal shock and high temperature pressure test, and EVM-2 has the requirement of thermal extension test. So EVM-1 needs to be a thermoplastic material (TPU) and EVM-2 needs to be a halogen-free cross-linked material.
