Differences between EV high voltage cables and EV charging cables
Since the voltage of the high-voltage cable is enough to pose a threat to the human body, the relevant standards stipulate that the color should be orange, which acts as a reminder and warning; but there is generally no requirement for the color of the charging cable.
The environment inside the car is complex. In order to ensure the safety of the car, the high-voltage cable is generally required to meet the wear resistance requirements; while the charging pile cable is often dragged for charging, and generally needs to meet the anti-rolling requirements of the mobile cable.
The ISO organization is responsible for formulating international standards for electric vehicle high-voltage lines; the IEC organization is responsible for the international standards for cable charging.
The high-voltage line of the electric vehicle must be able to withstand various liquids that may be exposed to the vehicle, including oil and water; the charging cable must be able to withstand various liquids in the living environment outside the vehicle.
The charging pile cable has higher requirements for impact resistance and UV resistance due to long-term exposure to the outdoors.
The internal wiring space of the car is small, and the high-voltage cable is fixedly laid. The static bending of each point must be small to be bent and coiled. The charging cable is a mobile laying, and the dynamic bending radius is also required.
In order to facilitate the laying of high-voltage lines of electric vehicles, high-voltage cables are mostly single-core; charging cables are usually multi-core integrated cables, including signal lines, control lines, power auxiliary lines, etc., to ensure accurate control and safety of the entire charging process. run.
The higher the heat resistance of the electric vehicle high-voltage line, the better, the higher the heat resistance, the greater the current carrying capacity, so at least it is required to be able to withstand a high temperature of 125 degrees, and some silicone materials can even reach 180-200 degrees; the charging line is resistant to high temperature The requirements are not so high, the temperature resistance is too high, and it is easy to burn the user.
The structures and materials of the two are also different. High-voltage cables are generally composed of conductors, insulation, shielding, and sheathing, and can have a shielding structure to shield electromagnetic interference; EV charging cables are generally composed of conductors, insulation, fillers, tapes, and sheaths.
