Kilowatt standard for AC cables for electric vehicles
China [CN] Charging pile is now a common power supplement equipment, but there are still a lot of people do not know how many square wires are needed to install charging pile. After all, the wiring thickness of the charging pile can not be unified, mainly by the charging pile's electrical storage capacity and the voltage that the wiring harness is subjected to when the power is circulating.
Take 7kw charging pile 100 meters with large cable as an example: Among them, the single-phase charging pile is generally 7KW(AC charging pile)I=P/U=7000/220=32A A copper core cable of 4 square millimeters should be used. The following describes the differences between single-phase and three-phase power cable standards.
Specific specifications reference: 7kw charging pile 100 meters with 4 square mm copper core cable can be used; Charging pile cable related manuals/regulations: Single-phase charging pile is generally 7KW (AC pile) l=P/U=7000/220=32A A copper core cable of 4 square millimeters should be used.
