New energy vehicle high voltage cable requirements

Green travel is a concept advocated now. Now short-distance public transportation is gradually replaced by new energy vehicles, so the requirements for high-voltage cables of new energy vehicles are higher. The following briefly introduces the requirements for high-voltage cables of new energy vehicles.

1. Voltage: The main difference from commonly used automotive cables is that the frame needs to be designed accordingto the rated voltage of 600 V, while if it is used in commercial vehicles and buses, the rated voltage can reach 1000 V.In comparison, the voltage rating may be higher. The cables used in cars driven by internal combustion engines are now designed to have a rated voltage of 60 V.

2. Temperature: Except for the high-temperature cabin or high-temperature cabin in the vehicle, the temperature of the other commonly used cables can reach 105℃, while the high-voltage cables used in new energy are usually higher than the ordinary values such as 125℃ or 150℃. Different places have different requirements for cables.

3. Working life:The recognized cable standard is 3000h, which is often used in long-term aging tests. There will be special requirements for applications in high-voltage fields, which may exceed 3,000 hours, and the cumulative operating time at the specified temperature may even reach 12,000 hours.

4. Safety signs: High voltage electricity will bring certain risks to users. High-voltage cables must be visually distinguished from ordinary cables, and safety warning signs must be printed on them.

The above content can be distinguished from the signs on the surface, which can provide safety guarantees for users.
