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 need to communicate and automatically control when necessary. Therefore, the charging process puts forward higher requirements for the charging cable. The charging cable not only needs to have the function of power transmission, but also needs to transfer the status and information of the vehicle and power battery to the charging pile for real-time interaction, and control the charging action under necessary conditions, so as to complete the charging process safely and reliably.
Safety requirements for electric vehicle charging cable:At present, the safety of electric vehicles has become the focus of the industry. In the charging and discharging process of electric vehicles, due to long time, high current intensity and high frequency of cable use, its safety should be highly valued. On the basis of ensuring good insulation performance, electric vehicle charging cable shall have high heat resistance and aging resistance. At the same time, it shall have good low smoke and flame retardant characteristics during combustion, so as to minimize loss and injury.
Basic technical requirements for electric vehicle charging cable:Most charging cable products in the market are produced based on these two standards, but with the further development of charging cable technology and the improvement of application requirements, there are great differences in the technical requirements of charging cables between the two standards.
The electric vehicle charging cable needs to be moved frequently in the process of use. It belongs to a mobile flexible cable, which needs to have considerable flexibility. Therefore, the insulating material and sheath material used also need to have good flexibility. Due to the interactivity of charging technology, the charging cable not only transmits energy from the connected distribution network to the electric vehicle, but also has the functions of transmitting vehicle information (such as charging current control, vehicle voltage information, insulation monitoring, etc.) and charging action control. It is a kind of comprehensive cable with both energy transmission and information transmission.
