OMG EV cable | How many square wires does the charging pile need

 OMG, a new energy charging pile cable head enterprise, compiled this article for you. How many square meters of cables are used for this charging pile.


OMG technicians answered that to understand the charging cable selection, we need to first understand the charging mode and charging current of the charging pile. In general, we can divide the charging methods into four types, the main differences are the use mode and charging speed.


Charging mode 1: charging mode 1 is a combination of single head charging gun + Cable + ordinary CEE plug connected to single-phase mains power


Charging mode 2: the combination mode is single head charging gun + Cable + control box + plug connected to single-phase mains power


Charging mode 3: the combination mode is double head charging gun + Cable + charging pile connected to single-phase power or three-phase power


Charging mode 4, the combination mode is charging gun + Cable + charging pile connected to DC


Their differences are: the difference between charging mode 2 and charging mode 1 is to increase the controller. Compared with charging mode 1, charging mode 2 has complete protection measures, including overvoltage, undervoltage, overcurrent, overtemperature and leakage power-off protection, while charging mode 1 has no protection measures. Compared with charging mode 1 and charging mode 2, charging mode 3 increases the charging current, improves the charging speed, and has a higher demand for charging safety. Charging mode 4 is DC charging gun;





Charging cable selection corresponding to charging mode


Charging mode 1:


In charging mode 1, because ordinary CEE plug is used to connect single-phase mains power, common 10a and 16A currents are used, and the corresponding cables are OMG 3 * 1.5 square cable and omega 3 * 2.5 square cable.




Charging mode 2:


Ordinary CEE plug is used to connect single-phase mains power. OMG 3 * 2.5 + 2 * 0.75 cable is used for rated current of 10A / 16a and omg3 * 4 + 2 * 0.75 cable is used for rated current of 16A / 32A. For safety consideration, 3 * 6 + 2 * 0.75 cable is recommended for 32A current.




For the selection of charging mode 3 cable, we mentioned above that the selection principle of charging cable is to determine the charging mode used and the output current of charging mode to select the corresponding cable. The common output currents of charging mode 3 include 16a, 32a, three-phase 32a, three-phase 63A and three-phase 125A, that is, the corresponding charging cables can be 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 and omg 5 * 35 + 2 * 0.75 cable.




Type selection of charging mode 4 cable. Charging mode 4 is DC charging, which has obvious advantages such as high charging current and fast charging speed, so it has higher requirements for safety and thicker cable diameter. The cable includes main power line, ground wire, auxiliary power line and control line, and has more requirements for cable. When selecting cable, pay attention to product flexibility and bending radius; High and low temperature resistance, oil resistance, acid and alkali resistance, water resistance, wear resistance, cracking resistance and UV resistance; Flame retardant performance; Conductivity, conductor temperature rise; Whether the materials comply with the latest RoHS & reach environmental protection standards will be more guaranteed if the products with product quality recognition are selected.


To sum up the above: for the charging model selection of electric vehicles, in principle, we determine the charging mode and the output current of the charging mode to select the corresponding cable.


It is worth noting that due to the different charging pile cable standards issued by various countries, we must use the corresponding national standard charging pile cable when exporting. If you choose the right charging point cable supplier, it is not difficult to decide. For example, OMG has passed the ISO 9001:2015 and IATF 16949:2016 system certification, in which the electric vehicle charging point cable has obtained the American UL, German TUV, Chinese CQC certification, Dekai certification, IEC certification and en50620 certification, which have included the standard requirements of charging point cables in major countries and markets. Entering OMG, we also see once again the strength of made in China. This is the only joint-stock company in China that only focuses on new energy vehicle cables, and is advancing into the foreign high-end market with the momentum of rapid development.

Description of cable requirements for electric vehicle charging modes

 With the development of science and technology, as a means of transportation for daily travel, cars will continue to change in the future trends. Among them, electric vehicle charging connectors and charging cables have become a trend for the development of electric vehicles. Electric vehicles generally have two charging connection methods, one is the vehicle's built-in matching charging connector, and the other is a common charging pile in public places. Compared with the charging pile that comes with the car's own charger, which charging efficiency is more efficient? First of all, compare the charging connectors of electric vehicles with charging piles: household appliances are all 220V, and the same is true for appliances with charging piles. Because the input power of the power supply is limited, it takes longer for the car to come with its own charger. On the contrary, charging piles in public places use three-phase alternating current, and the input power can reach 380V,...

Learn more about the development history of OMG cable manufacturer

 In modern society, cables play an obvious role in life. In the early 20th century: Simple cables based on copper wires began to be used for charging electric vehicles. However, the cable transmission efficiency and safety of this period were poor, making it difficult to meet the growing charging needs of electric vehicles. In the following decades: cable design was continuously optimized, using highly conductive metals, multi-layer insulation and intelligent control technology to significantly improve performance. Cables during this period had significant improvements in transmission efficiency and safety. International standardization: With the rapid development of global charging infrastructure, a number of international standards and specifications for cable connections have been introduced, laying the foundation for the standardized application of electric vehicle charging cables . These standards regulate the design, manufacturing, testing and use of cables to ensure safety a...
