Requirements for high voltage cables of new energy vehicles

Green travel is an idea advocated now. Now, the short-distance public transport mode is gradually replaced by new energy vehicles, and the requirements for high-voltage cables of new energy vehicles are higher. Let's briefly introduce the requirements for high-voltage cables of new energy vehicles.

1. Voltage: the main difference from common automobile cables is that the frame needs to be designed according to the rated voltage of 600 v. if it is applied in commercial vehicles and buses, the rated voltage can reach 1000 V. In comparison, the voltage limit may be higher. The cable used in cars driven by internal combustion engines is designed to have a rated voltage of 60 v.

2. Temperature: except for the high-temperature ones in the cabin or high-temperature cabin, the allowable temperature of other frequently used cables in the vehicle has reached 105 ℃, while that of new energy is higher

The pressure cable is usually higher than the normal value, such as 125 ℃ or 150 ℃. Different places have different requirements for cables.

3. Working life

The accepted cable standard is 3000h, which is often used in long-term aging tests. In the application of high-voltage field, there will be special requirements, which may exceed 3000 h, and the cumulative operating time at the specified temperature may even reach 12000 H.

4. Safety signs:

High voltage electricity will bring certain risks to users. High voltage cables should be visually distinguished from ordinary cables, and safety warning signs should be printed at the same time.

The above contents can be distinguished from the signs on the surface, so as to ensure the safety of users.
