What are the requirements for electric car charging lines?

Electric vehicle charging cable is the carrier connecting electric vehicle and charging pile, and its basic function is to transmit electric energy. However, with the development of charging technology, in order to better complete the charging process, electric vehicles and charging piles should be well communicated, and automatic adjustment should be made when necessary. Therefore, the charging process puts forward higher requirements on the charging cable. The charging line not only has the function of power transmission, but also transmits the state and information of the car and power battery to the charging pile for real-time interaction. Adjust the charging response if necessary to complete the charging process safely and reliably.

Nowadays, the safety factor of electric vehicle has become the focus of the industry. The safety factor of electric vehicle should be attached great importance because of its long charging and discharging time, high current intensity and high cable frequency. On the basis of good insulation performance, electric vehicle charging cable should have high heat resistance and aging resistance. At the same time, it should have good low smoke flame retardant characteristics to minimize the loss and injury.
