The new energy charging pile cable is a very common energy supply equipment, but there are still many people who don't know how many square meters of wires are needed to install the charging pile. The thickness of the wiring harness of the charging pile cannot be uniform, which is mainly determined by the power storage capacity of the charging pile and the voltage withstood when the wiring harness circulates power. Generally speaking, new energy charging pile cables are much thicker than other wires. Today, let us learn how to choose a suitable new energy charging pile cable when installing a charging pile. 1. Charging piles are divided into single-phase and three-phase. Whether it is two-phase or single-phase, it must first be converted into AC incoming line current. (1) Single-phase charging pile (AC charging pile) I=P/U. I=P/(U*1.732) Three-phase charging pile (DC charging pile) After calculating the current, select the cable according to the current. 2. The cable selection can refer to the relevant manuals or procedures as follows: (1) The single-phase charging pile is generally 7KW (AC charging pile) I=P/U=7000/220=32A and a copper core cable of 4 square millimeters should be used. (2) Three-phase charging pile (DC pile) 15KW current 23A cable 4 square millimeters. 10 square millimeters of 30KW current 46A cable. 92A cable 60KW current 25 square millimeters. 90KW current 120A cable 35 square millimeters. All charging piles should have a neutral wire and a ground wire. So single-phase three-core cable, three-phase five-core cable. .
