Standard types of charging cables for domestic or commercial electric vehicles

Nowadays, the electric vehicle field is trying to reduce the charging time and improve the charging efficiency. This is a physics lesson that applies the knowledge learned to the real world. It can improve people's new views on electric vehicles and have a higher understanding of the charging field.


Charging pile can be divided into single-phase and three-phase. Regardless of two-phase or single-phase, the current of AC incoming line shall be converted first, such as:

For single-phase charging pile (AC charging pile) I=P/U ;

For three-phase charging pile (DC charging pile), I=P/(U * 1.732) ;

After the current is calculated in this way, select the cable according to the current size.

Relevant manuals or procedures can be selected by cables, such as:


The single-phase charging pile is generally 7KW (AC charging pile), I=P/U=7000/220=32A, and 4 mm2 copper core cable shall be used;


Three phase charging pile (DC pile):

15KW current 23A cable 4mm2

30KW current 46A cable 10mm2

60KW current 92A cable 25mm2

90KW current 120A cable 35mm2


All charging posts shall have zero line and ground wire. Therefore, the single-phase cable shall have three cores, and the three-phase cable shall have five cores. Of course, consult professional automobile manufacturing cables for specific specifications and models, and see more series of standards.

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...
