When charging an electric vehicle, it is inseparable from the car charging cord. As a special component such as the car charging cord, charging the electric vehicle has a crucial purpose. However, with the continuous deepening of the vehicle use scene, the use of charging is also increasing. In order to better complete the charging, the charging process puts forward higher requirements for the car charging cord. What are the requirements for car charging cords for car charging?
For the requirements of the car charging cord, there are factors such as specifications, models, and quality requirements. In terms of the specifications and low resistance value of the car charging cord, the requirements for the cable need to meet the power of the charger. If the power is too low, it is easy to There are situations such as heat generation, spontaneous combustion, etc., so the selection needs to be selected according to the power of the charger. According to the power of the charger for charging the pure electric vehicle, the power of the household slow-charging charger matched with the vehicle is basically 3.5kw to 3.5kw. About 1.6kw, depending on the size of the battery capacity, and taking the power of the charger as an example of about 3.3kw, the current sockets and wires of household appliances can withstand a maximum power of about 3.5KW, according to the size of the copper core wire, 2.5 square millimeters is enough.
2.5 square meters can load about 5.5kw of 16A-25A power. Of course, if the charging distance of the electric vehicle is relatively far, then the requirements for the wire will be higher, which requires the resistance of the wire to be lower, for the size of the electric vehicle charging cable, the charging and discharging process of the electric vehicle, due to the long time, high current intensity, and high frequency of use of the cable, will lead to a larger current passing through; in this case, the following , you can use 4 square wires, 4 square wires can load the current size of 35A-40A, according to the power, it can reach nearly 8kw power.
In general, for the requirements of the car charging cord used for electric vehicle charging, on the basis of ensuring its good insulation performance, the car charging cord should have high heat resistance and aging resistance, and at the same time, the car charging cord should have good low-smoke flame retardant properties when burning.
