What are the requirements for electric vehicle charging cables?

China [CN]

Product description: Electric vehicles rely on electricity to drive the vehicle, so after using the electric vehicle for a period of time, the battery needs to be charged without electricity. Many consumers are confused about this charging problem, because unlike traditional fuel vehicles, electric vehicles can drive without refueling, but they must be charged for a period of time before driving, which is why consumers don’t know much about electric vehicles. When it comes to electric vehicle charging, we have to mention electric vehicle charging cables. Today I will introduce you to the requirements of electric vehicle charging cables.

Its functional requirements Electric vehicle charging cables are carriers that connect electric vehicles and charging piles, and their basic function is to transmit electrical 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 higher requirements on charging cables (EV cables). Charging cables not only require high-voltage cables (EV HV cables) to have power transmission functions, but also need to transmit the status and information of vehicles and power batteries to charging piles for real-time interaction, control the charging action under necessary conditions, and complete the charging process safely and reliably.

At present, the safety of electric vehicles has become the focus of attention in the industry. During the charging and discharging process of electric vehicles, the safety of cables should be highly valued due to their long service life, high current intensity and high frequency of use. On the basis of ensuring good insulation performance, electric vehicle charging cables should have high heat resistance and aging resistance. At the same time, they should have good low smoke and flame retardant properties during the combustion process to minimize losses and damage.
