Safety protection measures for electric vehicle charging cables

China [CN]

Today, society is facing tremendous pressure from energy and the environment, and is constantly looking for clean energy to replace traditional fuels to improve the current situation of worsening traffic emissions. Therefore, the emergence and application of new energy electric vehicles have gradually become the focus of society and automobile manufacturers. As well as the development of the new energy supporting facilities market industry, the market demand for electric vehicle charging pile cables has increased with the development of the market.

Of course, when using the electric vehicle charging pile charging cable, it should be able to determine whether the charging connector and the charging pile cable are connected correctly. When the charging connector is correctly connected to the battery system of the electric vehicle, the charging pile is allowed to start the charging process; when the charging pile detects that the battery system of the electric vehicle is abnormally connected, it immediately stops charging and sends effective information.

The charging pile should have charging protection functions: communication abnormality protection, insulation impedance detection protection, emergency shutdown protection, charging current abnormality protection, charging amount abnormality protection, voltage abnormality protection, leakage protection, charging gun overtemperature protection, battery temperature abnormality protection. The charging cable that meets the specifications of the charging pile and charging connector should be reasonably selected to effectively charge the electric vehicle in the user experience.

This is a must. As the current carrier connecting electric vehicles and charging piles, charging cables not only need to transmit information between the two, but also need to control charging. On the basis of ensuring excellent insulation performance, there is also a relatively good foundation. The cable has high aging resistance, heat resistance, oil resistance, weather resistance, etc. Due to frequent bending and dragging during use, the cable is also required to have flexibility and mechanical properties.
