Characteristics of AC charging cable for new energy applications

详情

Generally, according to the rated power of charging, it can be divided into 3.5kw and 7kw household charging piles. The rated current of 3.5kw charging piles is *6A, and that of 7kw charging piles is *2A. These two kinds of power charging piles are connected to household **0V single-phase power.

Product application: electric vehicle charging cable of which the AC cable is used for connecting cable of conductive charging interface of electric vehicle with AC rated voltage of *2V. It is suitable for families or public places to use power supply equipment equipped with control pilot circuit to provide AC charging power for electric vehicles. It is a charging cable product commonly used by electric vehicles.

Product features: high temperature resistance, flame resistance, good oil resistance, wear resistance, high mechanical strength, high flexibility, flexibility, easy installation and use. Flame retardant materials usually contain heteroatomic polymer materials, such as those containing bromine and phosphorus, which absorb the free radicals generated by combustion during the test combustion process and hinder the chain reaction. It will not burn and prevent the spread of combustion. High temperature resistance means that the original properties are still maintained under high temperature conditions, such as the Hooke coefficient, material wear resistance, sealing performance, etc., which means that the chemical properties will not change under high temperature conditions, and the physical properties will not change as much as possible. Oil resistance is mainly used to test the ability of materials to resist oil corrosion. For example, the materials are made into standard samples, soaked in oil of undetermined grade for a certain time, and then the volume growth or quality change of the product is calculated. The oil resistance of the product is judged by the test.

As the current carrier connecting the electric vehicle and the charging pile, the safety of the charging cable has always been the concern of the public. It is not only necessary to carry out the information transmission between the two, but also to control the charging. On the basis of ensuring the excellent insulation performance, the circuit features high aging resistance, heat resistance, oil resistance, weather resistance and other properties. Because it is often bent and dragged during use, Therefore, the flexibility and mechanical properties of the cable are also required.
