As the name implies, the electric vehicle charging cable is used to connect the charging gun and the charging infrastructure to transmit power to the electric vehicle, and is equipped with a certain number of signal lines, control lines, power auxiliary lines, etc. to ensure accurate control of the entire charging process and safe operation. . As a special component such as a charging cable, charging an electric vehicle has a vital purpose. However, as the vehicle usage scene continues to deepen, there are more and more uses for charging. In order to better Complete charging, therefore, the charging process puts higher demands on the charging cable So what are the requirements for electric vehicle charging on the wire?
The requirements for charging wires include specifications, models, quality and other factors. In terms of the specifications and low resistance of the wires, the requirements for the wires need to meet the power of the charger. If the power is too low, it is easy to generate heat. Spontaneous combustion and other situations, so the choice needs to be made according to the power of the charger. According to the power of the pure electric vehicle charger, the power of the household slow charging charger matched with the car is basically around 3.5kw to 1.6kw. The capacity of the battery depends on the size of the battery. Taking the power of the charger at about 3.3kw as an example, the sockets and wires of household appliances can withstand a maximum power of about 3.5KW, according to the size of the copper core wire in the national standard. See, 2.5 square millimeters is enough. 2.5 square meters can load a power of 16A-25A about 5.5kw. Of course, if the charging distance is relatively long, the requirements for the wire will be higher, which requires the resistance of the wire to be lower. , in terms of the size of the charging line of an electric vehicle, the charging and discharging process of an electric vehicle, due to the long time, high current intensity, and high frequency of use of the cable, will lead to a greater current passing through; in this case, A 4-square wire can be used, and a 4-square wire can carry a current of 35A-40A. According to the power, it can reach a power of about 8kw. Generally speaking, for the requirements of charging wires for electric vehicles, on the basis of ensuring that they have good insulation performance, they should have high heat resistance and aging resistance. At the same time, they should have good insulation performance when burning Low smoke flame retardant properties.
