How to choose the correct type of charging pile cable?

New energy green travel has become a new way of life. An indispensable topic is the issue of car charging. There are charging piles, charging stations, and household charging stations. So, how to choose the correct type of charging pile cable in different situations?

First of all, we need to understand the classification of charging modes, we can divide them into four modes. They are:

Charging mode 1: The combination of single-head charging gun + cable + ordinary CEE plug connected to single-phase mains

Charging mode 2: the combination of single-head charging gun + cable + ICCB controller + plug connected to single-phase mains

Charging mode 3: the combination of double-headed charging gun + cable + charging pile connected to single-phase electricity or three-phase electricity

Charging mode 4: combination of charging gun + cable + DC charging pile

After roughly understanding the four charging modes, you might as well know how to correctly select the cable in the corresponding mode.

In charging mode 1, the CEE plug is used to connect to the single-phase mains. The common currents are 10A and 16A. The corresponding cables can choose OMG 3*1.5 square cable, OMG 3*2.5 square cable;

The difference between charging mode 2 and mode 1 is only one more controller, the rated current 10A/16A chooses OMG 3*2.5+2*0.75 cable, the rated current 16A/32A chooses OMG 3*4.0+2*0.75 cable;

There are five common output currents in charging mode 3: 16A, 32A, three-phase 32A, three-phase 63A, and three-phase 125A, that is, the corresponding charging cables can be selected from OMG 3*4.0+2*0.75 cable, OMG 3*6.0 +2*0.75 cable, OMG 5*6.0+2*0.75 cable, OMG 5*16+2*0.75 cable, OMG 5*35+2*0.75 cable;

Charging mode 4 is DC charging, high current and fast charging speed are its obvious advantages, so the requirements for safety will be higher, the wire diameter of the cable is thicker, and the cable includes the main power cable and the ground wire and auxiliary power cable. , control line. When choosing cables, you need to pay attention to various product properties, such as high temperature resistance, flame retardant properties, etc. It is safer and more secure to choose products with quality certification.

The common output currents of charging mode 4 are 80A, 125A, 200A, 250A, and the corresponding charging cables can be selected from OMG 2*20+25+2*4.0+6*0.75 cable, OMG 2*35+25+ 2*4.0+6*0.75 cable, OMG 2*50+25+2*4.0+6*0.75 cable, OMG 2*80+25+2*4.0+6*0.75 cable.

The above are the corresponding selected cable products in the four modes. Generally speaking, the charging mode is first determined, and the corresponding cable is selected according to the size of the output current in the corresponding mode. The cable selection must be correct. Once the selection is inappropriate or unqualified The cable products are prone to safety accidents such as fire.
