Eight common material standards for car charging pile cables

China [CN]

As we all know, the core of the current development of new energy electric vehicles in the world is the problem of charging piles and charging cables. As a new industrial chain planning, the trillion-dollar market of "new infrastructure" charging piles is coming.

Today, charging piles are written into the government work report for the first time. We must strengthen the construction of new infrastructure (i.e. "new infrastructure"), develop a new generation of information networks, expand 5G applications, build charging piles, promote new energy vehicles, stimulate new consumer demand, and help industrial upgrading.

The following is an introduction to the characteristics of new infrastructure material standards:

Oil resistance: When gasoline is 23℃, 20h, the maximum outer diameter change rate is less than 15%; when it is diesel at 23℃, 20h, the maximum outer diameter change rate is less than 15%; when it is engine oil at 23℃, 20h, the maximum outer diameter change rate is less than 15%. In terms of oil resistance, the outer diameter change rate is between 15%-40% due to temperature and duration.

Water and acid and alkali resistance: the mechanical property change rate after immersion at 80°C for 168H, acid and alkali at 23°C for 186H is less than 30%

Tear and crack resistance: According to the test report, the value is greater than 15N/MM-40N/MM.

Bending resistance, can go back and forth tens of thousands of times, 2.5kv core wire withstand voltage.

According to market data statistics, the ratio of electric vehicles to charging piles in various regions is far from reaching the required value. In the future development of new energy infrastructure, it is necessary to keep up with the pace of the global new industrial chain and continue to move forward. In the development of core charging piles and charging cables, continue to explore new core technologies. For more information, please check the relevant dynamics:
