Performance requirements for high-voltage cables in the environment inside electric vehicles

With the rapid development and popularization of electric vehicles, high-voltage cables, as an important part of electric vehicles, play a key role in the in-vehicle application environment. This paper will introduce the importance and characteristics of high voltage cables for electric vehicles in the in-vehicle application environment.

1. Application in high-temperature environment: electric vehicle high-voltage cables face the challenge of high-temperature environment in the vehicle. Due to the high power charging and driving process of electric vehicles generates a large amount of heat, high voltage cables need to work properly in a high temperature environment. Therefore, high-voltage cables need to have good high-temperature resistance in the vehicle application environment, and can withstand high-temperature conditions for a long time without damage.

2. Anti-electromagnetic interference capability: Inside the car, there are various electronic devices and systems, such as car navigation and audio systems. These devices will produce electromagnetic interference, which affects the normal work of the high-voltage cable. Therefore, the electric vehicle high-voltage cable needs to have good anti-electromagnetic interference ability, can effectively shield the external interference signal, to ensure the stability and reliability of signal transmission.

3. Waterproof and dustproof performance: the vehicle environment is humid and dusty and other factors, which puts forward requirements for the safety and reliability of high-voltage cables. High-voltage cables need to have good waterproof and dustproof performance, can effectively prevent moisture and dust from entering the cable inside, to avoid causing short circuits, leakage and other safety issues.

4. Abrasion resistance: In the vehicle application environment, high-voltage cables may be subject to friction, extrusion and other external forces, so they need to have good abrasion resistance. The outer sheath material of the high voltage cable should have high abrasion resistance, which can effectively protect the conductor and insulation layer inside the cable and extend the service life of the cable.

To summarize, under various harsh in-vehicle conditions, high-voltage cables have to ensure that their mechanical properties are stable in order to work properly and ensure the safety and reliability of electric vehicles.OMG' has been deeply engaged in the field of electric vehicle cables for decades, and in the process of cable design and production, we take into account the temperature range, waterproof performance, corrosion resistance, insulation, voltage resistance, abrasion resistance, and bending performance, etc., so as to ensure that the high-voltage cables can work properly in various complex environments and provide efficient and safe energy transmission for electric vehicles. Moreover, OMG' in-vehicle high-voltage cables have passed a number of performance tests and comply with international standards such as ISO6722-1, ISO6722-2, ISO14572, LV216, ISO19642, UL758 (UL3820UL30088), and domestic standards based on QC/T1037, which are applicable to the actual situation in various regions.
