Liquid-cooled charging cables play an important role in Supercharging systems

As of the end of June, China's new energy vehicle ownership amounted to 16.2 million vehicles. Among them, 12.594 million pure electric vehicles, accounting for 77.8% of the total number of new energy vehicles, the overall trend of steady growth. With the popularization of new energy vehicles, the market also feedback related problems need to be solved. For example, the car's range is not enough, charging efficiency and safety to be mentioned, etc., the major car companies and new energy technology research and development enterprises also put forward solutions. At present, supercharging can help new energy vehicles to solve the charging problem, the principle is to increase the current of the charging pile and improve the voltage platform of the whole vehicle. This for charging transmission carrier charging cable is undoubtedly also need to make upgrading.

Conventional charging cable can not guarantee the safety and stability of the high voltage and high current charging process, it is necessary to increase the wire diameter and insulation thickness of the cable, but it will cause the cable is too thick, hard, bulky situation, not convenient for the user's practical use. And the cable cooling efficiency can not keep up with, will also cause the charging port heat accumulation, buried car spontaneous combustion hidden danger. Therefore, liquid-cooled charging cables have become the best choice for super charging piles due to their efficient heat dissipation performance and light weight. The advantages of liquid-cooled charging cable are introduced below:

1. Improve charging efficiency: Liquid-cooled charging cables utilize liquid-cooling technology to efficiently dissipate the heat generated in the cable through the internal circulation of coolant. Compared to traditional air cooling, liquid-cooled charging cables are able to lower the temperature of the cable more quickly and improve charging efficiency. Efficient charging process means shorter charging time, providing users with a more convenient charging experience.

2. Enhanced safety: In a supercharging system, the charging cable bears the important task of transmitting high currents. The high current will cause the cable to heat up, which may lead to potential safety hazards if it cannot dissipate the heat in time. Liquid-cooled charging cable can effectively reduce the temperature of the cable through the circulation of coolant, reducing safety risks. At the same time, liquid-cooled charging cables are also equipped with safety features such as overload protection and short-circuit protection to ensure the safety and reliability of the charging process.

3. Extending cable life: High current and high temperature are one of the main causes of cable aging and damage. Liquid-cooled charging cables effectively reduce the temperature of the cable through timely heat dissipation, which reduces the degree of heat applied to the cable, thus prolonging the life of the cable. The long life of the cable reduces the frequency of replacement and maintenance, and lowers the cost of use.

4. Light weight: Liquid-cooled charging cables, through cooling technology, do not require additional wire diameter cross-section and insulation thickness to assist current transmission. The high heat dissipation efficiency of the liquid-cooled charging cable ensures the normal operation of high power current, but also reduces the wire diameter size, making the cable more lightweight. It will not burden the user's daily process of plugging and unplugging the charging gun cable, optimizing the charging experience.

OMG' high power DC charging cable is a solution to increase DC charging current by utilizing liquid-cooling technology to keep the cable at a lower constant temperature during charging by cooling down the cable to overcome the heat damage caused by heat generation to the charging gun, charging cable, and charging pile. The principle is to add a liquid-cooled circulation system inside the cable, through the sealed circulation connection inside the charging gun, so that the cooling system and charging system coexist and work together in a structural form, to realize the car battery full in a short period of time or rapid replenishment of power. OMG' liquid-cooled charging cables have been certified by the European standard IEC62893, and have industry guarantee in terms of quality. OMG' is committed to providing customized technical solutions for new energy charging applications for global customers in response to their specific needs. With the continuous advancement of technology, liquid-cooled charging cables will be an indispensable part of the supercharging system in the future, providing users with a faster, safer and more reliable charging experience.
