Charging piles are very common energy supply equipment nowadays, but there are still many people who don't know how many square meters of wires are needed to install charging piles. The thickness of the wiring harness of the charging pile cannot be uniformly discussed. It is mainly determined by the power storage capacity of the charging pile and the voltage that the wiring harness withstands when the power is flowing. Generally speaking, the wires of the charging pile are much thicker than other wires. , Today, follow the editor of evcome to learn how to choose the right cable when installing the charging pile. 1. Charging piles are divided into single-phase and three-phase. Regardless of two-phase or single-phase, the first step is to convert to the AC incoming current. (1) For single-phase charging pile (AC charging pile) I=P/U (2) For three-phase charging pile (DC charging pile) I=P/(U*1.732) After calculating the current in this way, select the cable according to the current . 2. Cable selection can refer to relevant manuals or regulations such as: (1) Single-phase charging piles are generally 7KW (AC charging piles) I=P/U=7000/220=32A and copper core cables of 4 square millimeters should be used. (2) Three-phase charging pile (DC pile) 15KW current 23A cable 4 square millimeters 30KW current 46A cable 10 square millimeters 60KW current 92A cable 25 square millimeters 90KW current 120A cable 35 square millimeters All charging piles should have neutral and ground wires . Therefore, a single-phase three-core cable is required, and a three-phase five-core cable is required. .
