How many square meters of wire is needed for the charging station of a 2/3 wheeled vehicle?

How many square meters of wire is needed for the charging station of a 2/3 wheeled vehicle? Ordinary AC charging stations generally have an incoming line of 3.5kW16A for 3 * 4mm, 7kW12A for 3 * 6mm, and other functional products depend on the specific power.

1. Charging stations can be divided into single-phase and three-phase, regardless of whether they are single-phase or single-phase. The first step is to calculate the AC incoming current.
(1) For single-phase charging stations (AC charging stations), I=P/U
(2) For three-phase charging stations (DC charging stations), I=P/(U * 1.732)
After calculating the current in this way, select the cable based on the magnitude of the current.

2. Cable selection can be based on relevant manuals or regulations, such as:
(1) A single-phase charging station is generally 7KW (AC charging station) with I=P/U=7000/220=32A, and a copper core cable of 4 square millimeters should be used.
(2) Three phase charging station (DC station)
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 stations should have neutral and ground wires. So single-phase cables require three core cables, while three-phase cables require five core cables.
Installation of charging stations for hybrid or household power sources can be done using 4 or 6 square cables. For charging stations with a 40kW power output, it is recommended to use 1 * 16+1 * 10mm cables.
