High Voltage Cables For New Energy Vehicles

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.

The selection of high-voltage cables for new energy vehicles should take into account factors such as the cable's conductivity, heat resistance, ability to withstand environmental impacts, and safety standards. The following are some specific recommendations:

1. Selection according to the temperature rise curve and conductor characteristics:
- It is necessary to refer to the current-voltage values and consider the rated voltage and peak current.
- Combine with the ambient temperature and the maximum permissible temperature of the insulator to select the appropriate cable cross-section area.

2. Apply the calculation formula:
- Use the formula to calculate the required conductor cross-sectional area to ensure that the temperature rise of the cable does not exceed the permissible range at the rated current.

3. Consider the characteristics of the application occasions of the cable:
- High-voltage cables are used to connect the charging port with the battery, inside the battery, the battery with the engine and other components, so it is necessary to consider the conditions of small wiring space, high current and high voltage, high and low temperature environment.

4. Meet environmental and safety requirements:
- Choose cables that meet environmental and safety standards such as low-smoke halogen-free flame retardant to adapt to the harsh conditions such as salt spray, electromagnetic fields, oil and chemicals that may be encountered in the car driving environment.

5. Refer to commonly used standards:
- Understand and follow the common standards for high voltage cables for new energy vehicles to ensure that the performance of the cables meets industry requirements.

In summary, when selecting high-voltage cables for new energy vehicles, attention should be paid to the performance parameters of the cables to ensure that they can adapt to the complex in-vehicle environment and a variety of working conditions, while complying with the relevant safety and environmental standards.OMG', as an excellent international company, has been deeply engaged in the field of electric vehicle cables for decades and has an experienced team.
