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.
