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. In addition can also widely produce some customized products. Conductor materials include bare copper, tinned copper and aluminum alloy.
