Functional requirements for charging cables of electric vehicles

China [CN]

In terms of function, the electric vehicle charging cable is the carrier used to transmit electric energy between the electric vehicle and the charging pile. The modern charging technology has higher requirements for the charging process, that is, the information transmission between the electric vehicle and the charging pile is required, and the charging action can be properly controlled.

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, it is necessary to communicate between the electric vehicle and the charging pile, and carry out automatic control when necessary.

Therefore, electric vehicles rely on electricity to drive vehicles. Like the principle of traditional fuel vehicles, they need to be recharged when they find that the electricity is insufficient; The fuel car needs to be refueled because it is not enough. Because electric vehicles are not like traditional fuel vehicles, which can be driven without fuel, but only after a period of charging, which is why consumers do not understand electric vehicles very well. When it comes to charging electric vehicles, they have to provide electric vehicle charging cables.

At present, the safety of electric vehicles has become the focus of the industry. The charging and discharging process of electric vehicles should be highly valued for its long time, high current intensity and high frequency of cable use. On the basis of ensuring good insulation performance, the electric vehicle charging cable shall have high heat resistance and aging resistance, and at the same time, it shall have good low-smoke flame-retardant characteristics during combustion to ensure the minimum loss and damage.

From this point of view, in the two standards of IEC 60245 and IEC 60227, cable insulation materials and sheath materials that can be used in mobile applications are specified. Of course, multiple standard certification is an affirmation of product quality, which makes users more comfortable. It also has certain guarantee for the use time of the car.
