Characteristics of liquid-cooled high-power cables for electric vehicles

China [CN]

Liquid-cooled cables are advanced conductive materials that can reduce the operating temperature of the cable by soaking the conductive material in a coolant. Compared with traditional air-cooled cables, liquid-cooled cables have higher thermal conductivity and can dissipate heat more efficiently, thereby improving the cable's power transmission capabilities.

The working principle of liquid-cooled cables is to immerse conductive materials in a coolant with good thermal conductivity, and through the circulation of the coolant, the heat generated inside the cable is taken away. The coolant can be water, oil or other media with good thermal conductivity, and can be selected according to specific application scenarios.

In order to increase the charging rate and adapt to the use of high-power charging, the current mainstream method of high-power charging cables is to increase the cross-sectional area to increase the load-bearing capacity of the cable, but this will not only make the cable heavier, but also make the cable harder. . Increasing cable cross-section also reduces cable flexibility in today's cold, low-pressure weather. The cable will then become stiff and heavy. At present, the traditional high-current fast charging route has hit the ceiling. How to further improve the performance of the cable while reducing the weight of the cable and making the cable easier to use is an urgent problem to be solved.

The currently available liquid-cooled charging cables can meet the performance requirements of high-current charging, while reducing weight and making them more convenient to use. A liquid-cooled charging cable is actually a charging cable that uses a liquid cooling system to reduce the temperature of the charging cable and charging equipment. The main purpose is to add a liquid cooling circulation system inside the cable to achieve cooling, so that the cable can be charged at a lower temperature without overheating. It is light in weight and has good current-carrying effect. It can achieve fast charging in a short time and meet people's high-power charging needs. Please visit: https://www.omgevcable.com
