Safety Protection Measures for Electric Vehicle Charging Cables

Nowadays, society is facing enormous pressure from energy and the environment to continuously seek clean energy to replace traditional fuels and improve the deteriorating situation of transportation emissions. Therefore, the emergence and application of new energy electric vehicles have gradually become the focus and concern of society and automobile manufacturers. The development of projects in the new energy supporting facilities market has become a focus, and with the development of the market, the market demand for electric vehicle charging pile cables has increased.


Of course, when using the charging cable of an electric vehicle charging station, it should be possible to determine whether the charging connector is correctly connected to the charging station cable. Allow the charging station to start the charging process when the charging connector is correctly connected to the battery system of the electric vehicle; When the charging station detects abnormal connection of the electric vehicle battery system, it immediately stops charging and sends a valid message.


The charging station should have charging protection functions: communication abnormal protection, insulation impedance detection protection, emergency shutdown protection, charging current abnormal protection, charging amount abnormal protection, voltage abnormal protection, leakage protection, charging gun over temperature protection, and battery temperature abnormal protection. Reasonable selection of charging cables that meet the specifications of charging stations and charging connectors should be made to effectively charge electric vehicles through user experience.


This is necessary. As the current carrier connecting electric vehicles and charging stations, 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, they also have a good foundation. The high aging resistance, heat resistance, oil resistance, and weather resistance of cables require flexibility and mechanical properties due to frequent bending and dragging during use. The charging station cable can be used indoors or outdoors. When used outdoors, the charging pile cable should meet the erosion of high cold, sunlight, rainwater, and automotive oil, which requires the cable to have suitable UV resistance, ozone resistance, and high and low temperature resistance for the use occasion. Special properties, such as chemical erosion, etc.
