For charging piles with a power of 7kW, when using a 220V power supply for power supply, you need to choose a suitable wire. Normally, it is recommended to use a 6 square copper core wire.
First of all, we need to understand the current demand of the charging station. The working current of the charging pile varies depending on the model and configuration, generally speaking, the current of the charging pile is around 30A. Considering the large power of the charging pile, in order to ensure the normal operation of the charging pile and avoid safety problems, theoretically 4 square copper core wires can be used, and if conditions permit, it is recommended to use 6 square copper core wires.
Secondly, we need to consider the load-bearing capacity of the wire. The wire carrying capacity is related to the specification and material of the wire. The carrying capacity of the 4 square copper core wire is about 45A, which can theoretically meet the current demand of the charging pile. However, considering the long charging time and excessive current, it is recommended to use a 6 square wire to be safer and more secure.
Finally, there are other factors to consider, such as power distance, outlet location, etc. If the power supply is far away or the location of the outlet is complicated, it may affect the use of the wire. When choosing a wire, you need to consider it comprehensively according to the actual situation.
In short, for the 7kw charging pile 220V, it is recommended to use 6 square copper core wires to meet the power demand. At the same time, choose wire products with reliable quality and meet safety standards, and consider other factors to ensure the normal operation of the charging pile and the safety of electricity.
