What are the requirements for electric car charging lines?

The electric vehicle charging cable serves as a bridge between the electric vehicle and the charging pile, primarily transmitting electrical energy. However, as charging technology advances, there is a growing need for effective communication between electric vehicles and charging piles, requiring the charging cable to adapt accordingly. In addition to power transmission, the charging cable must now facilitate real-time interaction between the car, power battery, and charging pile, conveying their status and information. This allows for necessary adjustments in the charging process to ensure safety and reliability. As a result, the charging cable has evolved beyond its initial function of power transmission and plays a crucial role in facilitating efficient and secure charging.

In recent times, the electric vehicle industry has been focusing more on enhancing the safety aspect of the vehicles. This safety concern is prioritized due to the extended period required for charging and discharging the vehicle, along with the high intensity of current and cable frequency. The electric vehicle charging cable must possess excellent insulation properties, besides high heat resistance and aging resistance, to ensure its safety standards. In addition, it should exhibit good quality of low smoke and flame retardation to minimize the extent of injury or loss, if any untoward incident occurs.
