Selection principle of charging pile charging cable diameter

The development of electric vehicles has become a global consensus, and charging of electric vehicles is inseparable from charging piles. Charging piles are divided into wall-mounted and standing charging piles, which are commonly installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. Critical infrastructure for electric vehicle charging. Many people do not know how to choose the appropriate charging cable for the charging pile. The selection principle is to choose according to the output voltage and power of the charging pile.

A 4-square or 6-square OMG cable can be used to install a charging pile for a hybrid or household power supply. It is recommended to use a 1*16+1*10mm cable for a 40kW power charging pile.

For example, the charging current of 32AH lead-acid is generally 3.5A, the second group is 7A, the maximum output power is 70V*7A=490W/0.8/220V=2.78A, the maximum input current on 220V is also about 3A, the copper core is The line 1.5 is enough. In addition to the selection of the line diameter of the fixed formula, the distance between the vehicle charging interface and the charging pile needs to be considered during wiring. The longer the distance, the longer the cable is required, and the larger the wire diameter is usually.

All in all, after theoretically selecting a suitable charging cable based on the output power of the charging pile, it is also necessary to check whether the distance is appropriate before purchasing according to the actual situation.
